  • Positioning element under another

    - by Cedar Jensen
    I am not an expert web-dev so please bear with me here. I would like to display a banner style header for a page with the top part taken up by an image that is 275x116 and then a horizontal menu bar (styled using ul items) appearing at 70% from the top of the banner. How would I set this up so that the banner appears underneath my navigation? Currently, a portion of the left side of my menu bar sits underneath the image but I'd like it to be the opposite so the menu bar is above the image, some thing like this: ============= <start of header> =========== -------- | img | | | | Horizontal menu | | -------- ============= <end of header> =========== My css: #header { background-color: green; border: 0; margin: 0; padding: 0; overflow: hidden; width: 100%; height: 120px; } #logo { background: green url(images/logo.png) no-repeat scroll 0 0; margin: 0px 0px; border: 1px solid white; left: 20px; top: 20px; width: 275px; height: 116px; position: absolute; z-index: -1000; } .container { border:1px solid grey; margin-left:auto; margin-right:auto; width:960px; } My Html: <body> <div id="header"> <div id="logo"> </div> <div class="container" id="primaryNavbar"> <ul> <li><a href="#">Home</a></li> <li><a href="#">Books</a></li> <li><a href="#">Shows</a></li> <li><a href="#">Movies</a></li> </ul> <div class="clear">&nbsp;</div> </div> <!-- end of container --> </div> <!-- end of header --> </body> I thought that setting the position to "absolute" for the logo element and adding in a very low z-index would achieve this but that isn't the case here. Any suggestions?

  • Ajax doesn't trigger a change-event on a webkit based browser

    - by user319464
    I have adapted a Jquery plugin to for-fill my needs to send GET requests to servers as a way of "pinging" them. I've also added some javascript code to add some fancy features like: depending on the changed value in a that the Jquery plugin changes, it changes the Icon accordingly. To make it all work essentially, I made so that when Ajax gets a "complete" event, it forces a "onChange" event to the span, triggering the javascript validation function to change the status icons. Here is the code of my slightly modified jQuery Plugin: /** * ping for jQuery * * Adapted by Carroarmato0 (to actually work instead of randomly "pinging" nowhere instead of faking * * @auth Jessica * @link http://www.skiyo.cn/demo/jquery.ping/ * */ (function($) { $.fn.ping = function(options) { var opts = $.extend({}, $.fn.ping.defaults, options); return this.each(function() { var ping, requestTime, responseTime ; var target = $(this); var server = target.html(); target.html('<img src="img/loading.gif" alt="loading" />'); function ping() { $.ajax({url: 'http://' + server, type: 'GET', dataType: 'html', timeout: 30000, beforeSend : function() { requestTime = new Date().getTime(); }, complete : function() { responseTime = new Date().getTime(); ping = Math.abs(requestTime - responseTime); if (ping > 2000) { target.text('niet bereikbaar'); } else { target.text(ping + opts.unit); } target.change(); } }); } ping(); opts.interval != 0 && setInterval(ping,opts.interval * 1000); }); }; $.fn.ping.defaults = { interval: 3, unit: 'ms' }; })(jQuery); target.change(); is the code that triggers the "onchange" event in the span: echo " <td class=\"center\"><span id=\"ping$pingNb\" onChange=\"checkServerIcon(this)\" >" .$server['IP'] . "</span></td>"; In Firefox this works, checkServerIcon(this) gets executed and passes the span object to the function. function checkServerIcon(object) { var delayText = object.innerHTML; var delay = delayText.substring(0, delayText.length - 2); if ( isInteger(delay) ) { object.parentNode.previousSibling.parentNode.getElementsByTagName('img')[0].src = 'img/servers/enable_server.png'; } else { if (delay == "bezig.") { object.parentNode.previousSibling.parentNode.getElementsByTagName('img')[0].src = 'img/servers/search_server.png'; } else { object.parentNode.previousSibling.parentNode.getElementsByTagName('img')[0].src = 'img/servers/desable_server.png'; } } } My guess would be that there's something different in WebKit browsers in the way object.parentNode.previousSibling.parentNode. .... works...

  • How to Pass a JS Variable to a PHP Variable

    - by dmullins
    Hello: I am working on a web application that currently provides a list of documents in a MySql database. Each document in the list has an onclick event that is suppose to open the specific document, however I am unable to do this. My list gets popluated using Ajax. Here is the code excerpt (JS): function stateChanged() { if (xmlhttp.readyState==4) { //All documents// document.getElementById("screenRef").innerHTML="<font id='maintxt'; name='title'; onclick='fileopen()'; color='#666666';>" + xmlhttp.responseText + "</font>"; } } } The onclick=fileopen event above triggers the next code excerpt, which downloads the file (JS): function stateChanged() { if (xmlhttp.readyState==4) { //Open file var elemIF = document.createElement("iframe"); elemIF.src = url; elemIF.style.display = "none"; document.body.appendChild(elemIF); } } } Lastly, the openfile onclick event triggers the following php code to find the file for downloading (php): $con = mysql_connect("localhost", "root", "password"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("Documents", $con); $query = mysql_query("SELECT name, type, size, content FROM upload WHERE name = NEED JS VARIABLE HERE"); $row = mysql_fetch_array($query); header ("Content-type: ". $row['type']); header ("Content-length: ". $row['size']); header ("Content-Disposition: attachement; filename=". $row['name']); echo $row['content']; This code works well, for downloading a file. If I omit the WHERE portion of the Sql query, the onclick event will download the first file. Somehow, I need to get the screenRef element text and change it into a variable that my php file can read. Does anyone know how to do this? Also, without any page refreshes. I really appreciate everyone's feedback and thank you in advance. DFM

  • jQuery, get datas in AJAX (done) then, display them as star (error)

    - by Tristan
    Hello, In my website, there are 2 steps : I get values from another domain with AJAX, it's numbers 100% working Then, i want to display those numbers in stars with this plugin (http://stackoverflow.com/questions/1987524/turn-a-number-into-star-rating-display-using-jquery-and-css) The error : the stars plugin does not work for the value i recieve from my ajax request, but it's working for my values for my domain which are not JS manipulated you can see a demo here http://www.esl.eu/fr/test/test_atome/?killcache=true PS: the data in ajax are provided in JSON-P so i wrote a parser which look like this: jQuery.ajax({ type: "get", dataType: "jsonp", url: "http://www.foo.com/", data: {demandeur: "monkey" }, cache: true, success: function(data, textStatus, XMLHttpRequest){ var obj = null, length = data.length; for (var i = 0; i < length; i++) { widget = "<p>AVERAGES<p>"; widget += "<p><span class='stars'>"; widget += data[i].services; widget += "</span></p>"; widget += "<p><span class='stars'>"; widget += data[i].qualite; widget += "</span></p>"; jQuery('#gotserv').html(widget); } } }); }); Then i have the star plugin after this function : $.fn.stars = function() { $(this).each(function() { // Get the value var val = parseFloat($(this).html()); // Make sure that the value is in 0 - 5 range val = val 5 ? 5 : (val < 0 ? 0 : val); // Calculate physical size var size = 16 * val; // Create stars holder var stars = $(''); // Adjust yellow stars' width stars.find('span').width(size); // Replace the numerical value with stars $(this).replaceWith(stars); }); I hope you understand, i don't know if i'm clear Thank you

  • HttpClient response handler always returns closed stream

    - by Alex Ciminian
    I'm new to Java development so please bear with me. Also, I hope I'm not the champion of tl;dr :). I'm using HttpClient to make requests over Http (duh!) and I'd gotten it to work for a simple servlet that receives an URL as a query string parameter. I realized that my code could use some refactoring, so I decided to make my own HttpResponseHandler, to clean up the code, make it reusable and improve exception handling. I currently have something like this: public class HttpResponseHandler implements ResponseHandler<InputStream>{ public InputStream handleResponse(HttpResponse response) throws ClientProtocolException, IOException { int statusCode = response.getStatusLine().getStatusCode(); InputStream in = null; if (statusCode != HttpStatus.SC_OK) { throw new HttpResponseException(statusCode, null); } else { HttpEntity entity = response.getEntity(); if (entity != null) { in = entity.getContent(); // This works // for (int i;(i = in.read()) >= 0;) System.out.print((char)i); } } return in; } } And in the method where I make the actual request: HttpClient httpclient = new DefaultHttpClient(); HttpGet httpget = new HttpGet(target); ResponseHandler<InputStream> httpResponseHandler = new HttpResponseHandler(); try { InputStream in = httpclient.execute(httpget, httpResponseHandler); // This doesn't work // for (int i;(i = in.read()) >= 0;) System.out.print((char)i); return in; } catch (HttpResponseException e) { throw new HttpResponseException(e.getStatusCode(), null); } The problem is that the input stream returned from the handler is closed. I don't have any idea why, but I've checked it with the prints in my code (and no, I haven't used them both at the same time :). While the first print works, the other one gives a closed stream error. I need InputStreams, because all my other methods expect an InputStream and not a String. Also, I want to be able to retrieve images (or maybe other types of files), not just text files. I can work around this pretty easily by giving up on the response handler (I have a working implementation that doesn't use it), but I'm pretty curious about the following: Why does it do what it does? How do I open the stream, if something closes it? What's the right way to do this, anyway :)? I've checked the docs and I couldn't find anything useful regarding this issue. To save you a bit of Googling, here's the Javadoc and here's the HttpClient tutorial (Section 1.1.8 - Response handlers). Thanks, Alex

  • CakePHP HABTM: Editing one item casuses HABTM row to get recreated, destroys extra data

    - by leo-the-manic
    I'm having trouble with my HABTM relationship in CakePHP. I have two models like so: Department HABTM Location. One large company has many buildings, and each building provides a limited number of services. Each building also has its own webpage, so in addition to the HABTM relationship itself, each HABTM row also has a url field where the user can visit to find additional information about the service they're interested and how it operates at the building they're interested in. I've set up the models like so: <?php class Location extends AppModel { var $name = 'Location'; var $hasAndBelongsToMany = array( 'Department' => array( 'with' => 'DepartmentsLocation', 'unique' => true ) ); } ?> <?php class Department extends AppModel { var $name = 'Department'; var $hasAndBelongsToMany = array( 'Location' => array( 'with' => 'DepartmentsLocation', 'unique' => true ) ); } ?> <?php class DepartmentsLocation extends AppModel { var $name = 'DepartmentsLocation'; var $belongsTo = array( 'Department', 'Location' ); // I'm pretty sure this method is unrelated. It's not being called when this error // occurs. Its purpose is to prevent having two HABTM rows with the same location // and department. function beforeSave() { // kill any existing rows with same associations $this->log(__FILE__ . ": killing existing HABTM rows", LOG_DEBUG); $result = $this->find('all', array("conditions" => array("location_id" => $this->data['DepartmentsLocation']['location_id'], "department_id" => $this->data['DepartmentsLocation']['department_id']))); foreach($result as $row) { $this->delete($row['DepartmentsLocation']['id']); } return true; } } ?> The controllers are completely uninteresting. The problem: If I edit the name of a Location, all of the DepartmentsLocations that were linked to that Location are re-created with empty URLs. Since the models specify that unique is true, this also causes all of the newer rows to overwrite the older rows, which essentially destroys all of the URLs. I would like to know two things: Can I stop this? If so, how? And, on a less technical and more whiney note: Why does this even happen? It seems bizarre to me that editing a field through Cake should cause so much trouble, when I can easily go through phpMyAdmin, edit the Location name there, and get exactly the result I would expect. Why does CakePHP touch the HABTM data when I'm just editing a field on a row? It's not even a foreign key!

  • jquery How to refresh pages when resize happens?

    - by Maju
    I have some indicator displays settings which float above a menu. Problem is when someone resizes the 'indicators stays on the same place', the page needs to 'refreshed to position correctly'. How to have a page refresh by itself when it detects the page is being resized? or is there any better way to do it? jQuery function findPosY(b) { var a = 0; if (b.offsetParent) { while (1) { a += b.offsetTop; if (!b.offsetParent) { break } b = b.offsetParent } } else { if (b.y) { a += b.y } } return a } function findPosX(b) { var a = 0; if (b.offsetParent) { while (1) { a += b.offsetLeft; if (!b.offsetParent) { break } b = b.offsetParent } } else { if (b.x) { a += b.x } } return a } function setNotifications() { $("#shortcut_notifications span").each(function () { if ($(this).attr("rel") != "") { target = $(this).attr("rel"); if ($("#" + target).length > 0) { var a = findPosY(document.getElementById(target)); var b = findPosX(document.getElementById(target)); $(this).css("top", a - 31 + "px");//-24 $(this).css("left", b + 83 + "px")//+60 } } }); $("#shortcut_notifications").css("display", "block") } CSS #shortcut_notifications { display:none; } .notification { color:#fff; font-weight:700; text-shadow:1px 0 0 #333; background:transparent url(../images/bg_notification.png) no-repeat center; position: absolute;/*absolute*/ width:37px;/*37*/ height:37px; display:block; text-align:center; padding-top:17px; color:#ffffff; } #nav li { display:block; float:right; padding:19px 21px; text-align: left; position:relative; height:24px; font-size:16px; } HTML <li class="settings"><a class="settings" href="#">Settings</a> <ul> <li><a href="#">Game Settings</a></li> <li><a href="#">Transactions </a></li> </ul> </li>

  • Need to optimize this PHP script for "recent posts". Fatal error when post count is high...

    - by Scott B
    The code below is resulting in an error on a site in which there are ~ 1500 posts. It performs fine when post count is nominal, however, this heavy load is exposing the weakness of the code and I'd like to optimize it. Interestingly, when I disable this menu and instead use the "Recent Posts" widget, the posts are drawn fine. So I'd probably do good to borrow from that code if I knew where to find it, or better yet, If I could call the widget directly in my theme, passing it a post count variable. Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 16384 bytes) in /home1/est/public_html/mysite/wp-includes/post.php on line 3462 The code is below. Its purpose is to list "recent posts". global $post; $cat=get_cat_ID('myMenu'); $cathidePost=get_cat_ID('hidePost'); $myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$cathidePost",'showposts' => $count-of-posts)); $myrecentposts2 = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$cathidePost",'showposts' => -1)); $myrecentpostscount = count($myrecentposts2); if ($myrecentpostscount > 0) { ?> <div class="recentPosts"><h4><?php if ($myHeading !=="") { echo $myHeading; } else { echo "Recent Posts";} ?></h4><ul> <?php $current_page_recent = get_post( $current_page ); foreach($myrecentposts as $idxrecent=>$post) { if($post->ID == $current_page_recent->ID) { $home_menu_recent = ' class="current_page_item'; } else { $home_menu_recent = ' class="page_item'; } $myclassrecent = ($idxrecent == count($myrecentposts) - 1 ? $home_menu_recent.' last"' : $home_menu_recent.'"'); ?> <li<?php echo $myclassrecent ?>><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li> <?php } ; if (($myrecentpostscount > $count-of-posts) && $count-of-posts > -1){ ?><li><a href="<?php bloginfo('url'); ?>/recent">View All Posts</a></li><?php } ?></ul></div>

  • Joomla - Force File Download / CSV Export

    - by lautaro.dragan
    I'm in need of help... this is my first time asking a question in SO, so please be kind :) I'm trying to force-download a file from php, so when the user hits a certain button, he gets a file download. The file is a csv (email, username) of all registered users. I decided to add this button to the admin users screen, as you can see in this screenshot. So I added the following code to the addToolbar function in administrator/components/com_users/views/users/view.html.php: JToolBarHelper::custom('users.export', 'export.png', 'export_f2.png', 'Exportar', false); This button is mapped to the following function in the com_users\controller\users.php controller: public function exportAllUsers() { ob_end_clean(); $app = JFactory::getApplication(); header("Content-type: text/csv"); header("Content-Disposition: attachment; filename=ideary_users.csv"); header("Pragma: no-cache"); header("Expires: 0"); echo "email,name\n"; $model = $this->getModel("Users"); $users = $model->getAllUsers(); foreach ($users as $user) { echo $user->email . ", " . ucwords(trim($user->name)) . "\r\n"; } $app->close(); } Now, this is actually working perfectly fine. The issue here is that after I download a file, if I hit any button in the admin that causes a POST, instead of it performing the action it should, it just downloads the file over again! For example: I hit the "Export" button "users.csv" downloads Then, I hit the "search" button "users.csv" downloads... what the hell? I'm guessing that when I hit the export button, a JS gets called and sets a form's action attribute to an URL... and expects a response or something, and then other button's are prevented from re-setting the form's action attribute. I can't think of any real solution for this, but I'd rather avoid hacks if possible. So, what would be the standard, elegant solution that joomla offers in this case?

  • iPhone - database reading method and memory leaks

    Hi, in my application, a RSS reader, I get memory leaks that I can't fix because I can't understand from where they come from. Here is the code pointed out by Instruments. -(void) readArticlesFromDatabase { [self setDatabaseInfo]; sqlite3 *database; articles = [[NSMutableArray alloc] init]; if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) { const char *sqlStatement = "select * from articles"; if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) { while(sqlite3_step(compiledStatement) == SQLITE_ROW) { NSString *aName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 1)]; NSString *aDate = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)]; NSString *aUrl = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 3)]; NSString *aCategory = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 4)]; NSString *aAuthor = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 5)]; NSString *aSummary = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 6)]; NSMutableString *aContent = [NSMutableString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 7)]; NSString *aNbrComments = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 8)]; NSString *aCommentsLink = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 9)]; NSString *aPermalink = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 11)]; [aContent replaceCharactersInRange: [aContent rangeOfString: @"http://www.mywebsite.com/img/action-on.gif"] withString: @"hellocoton-action-on.gif"]; [aContent replaceCharactersInRange: [aContent rangeOfString: @"hhttp://www.mywebsite.com/img/action-on-h.gif"] withString: @"hellocoton-action-on-h.gif"]; [aContent replaceCharactersInRange: [aContent rangeOfString: @"hthttp://www.mywebsite.com/img/hellocoton.gif"] withString: @"hellocoton-hellocoton.gif"]; NSString *imageURLBrut = [self parseArticleForImages:aContent]; NSString *imageURLCache = [imageURLBrut stringByReplacingOccurrencesOfString:@":" withString:@"_"]; imageURLCache = [imageURLCache stringByReplacingOccurrencesOfString:@"/" withString:@"_"]; imageURLCache = [imageURLCache stringByReplacingOccurrencesOfString:@" " withString:@"_"]; NSString *uniquePath = [tmp stringByAppendingPathComponent: imageURLCache]; if([[NSFileManager defaultManager] fileExistsAtPath: uniquePath]) { imageURLCache = [@"../tmp/" stringByAppendingString: imageURLCache]; [aContent replaceCharactersInRange: [aContent rangeOfString: imageURLBrut ] withString: imageURLCache]; } Article *article = [[Article alloc] initWithName:aName date:aDate url:aUrl category:aCategory author:aAuthor summary:aSummary content:aContent commentsNbr:aNbrComments commentsLink:aCommentsLink commentsRSS:@"" enclosure:aPermalink enclosure2:@"" enclosure3:@""]; [articles addObject:article]; article = nil; [article release]; } } sqlite3_finalize(compiledStatement); } sqlite3_close(database); } ` I have a lot of "Article" leaked and NSString matching with these using : [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, X)]; I tried a lot of different code I always have these leaks. Anyone has got an idea to help me?

  • What happens when several Java servlet apps running on the same port ?

    - by Frank
    Something strange happened to my servlets and I think I've figured out why, yet I'm more confused. I used Netbean6.7 to develop a Paypal IPN (Instant Payment Notification) message servlet, it listens on port 8080 by default for Paypal IPN messages. I used some sample Java code from it's web site, but when it ran, only about 1 in 10 messages came through, and they looked correct, but why 1 in 10 ? Not 100% or none ? So I asked some questions here and got some advices, one in particular points me to Google's App Engine, so I downloaded it and ran the demo guestbook while my IPN servlet is still running on Netbeans, the strange thing happened, after I entered "appengine-java-sdk-1.3.2\bin\dev_appserver.cmd appengine-java-sdk-1.3.2\demos\guestbook\war" from the command prompt, I went to the following url on my browser "http://localhost:8080/", I thought I would see the Google demo guestbook page, NO, what I saw was another servlet I developed 2 years ago : "Web Academy", online course registration app. How can that happen ? I never started it, and I haven't touch that project for years. I guess because it's also listening on port 8080, so now I understand why the IPN messages only came through 1 in 10 times, because another servlet was also listening on that port and could have got the messages intended for IPN, or some how those two servlets' processes mixed up and therefore couldn't respond to Paypal properly, and failed. In order to verify some of my guesses, I turn off Netbeans, and ran the Google guestbook again at the prompt, this time on my browser http://localhost:8080/ points to the demo guestbook page. My Urls look like this : [A] Paypal IPN : http://localhost:8080/PayPal_App/PayPal_Servlet [B] Web Academy : http://localhost:8080/ So now, my questions are : <1> Why the "Web Academy" servlet was auto started when I ran the Paypal servlet ? <2> If I change the IPN listening port to 8083, would that mean I can run both of them on my PC at the same time without affecting each other ? <3> But I still don't understand, [A] and [B] look different, if a page for [A] is refreshed, it should show the Paypal content, and another page looking at [B] should show the Web Academy content, and that's exactly what happens when I started Netbeans to run the Paypal servlet, both pages show their respective content correctly side by side without interfering with each other, how come the IPN messages couldn't get through 100% of the time ? <4> In Netbeans how to assign 8080 to servlet [A] and assign port 8083 to servlet [B] ? <5> How to turn off auto start of Web Academy by Netbeans ?

  • One click to trigger several search forms?

    - by Christian
    Hello, I have 1 main search form with a submit button and several secondary search forms with submit buttons. What I would like to do is when I enter text and click on the submit button of the main search form, the same text gets copied in all of the secondary search forms and all the submit buttons of the secondary search forms get automatically hit. The HTML code for the mains earch form is shown below: <form action="query.php" method="get"> Search: <input type="text" name="item" size="30"> <input type="submit" value="send"> </form> One of the several secondary search forms is shown below: <FORM action="http://www.dpbolvw.net/interactive" method="GET" target="_blank"> <div style="float: left; padding: 0 3px 0 0;"> <INPUT type="text" name="src" size="9" value="<?php $input = $_GET['item']; echo $input;?>" style="width: 110px; height: 22px;margin:0; padding: 0; font-size:140%;"> </div> <div style="float: left; padding: 0 3px 0 0;"> <input type="image" name="submit" value="GO" src="http://images.guitarcenter.com/Content/GC/banner/go.gif" alt="Search" style="font-size:140%"> /div> <input type="hidden" name="aid" value="1234"/> <input type="hidden" name="pid" value="1234"/> <input type="hidden" name="url" value="http://www.guitarcenter.com/Search/Default.aspx"/> </form> Notice the php code that I put in the "value" field of the secondary search form: <?php $input = $_GET['item']; echo $input;?> This automatically copies the text that I entered in the main search form into the secondary search form. I thus figured out how to do that. The problem is to "simulate" an "Enter" keystroke or a click on the "GO" button with the mouse on the secondary search form when the user hits the Enter key or hits the "SEND" button with the mouse on the main search form. Thank you for your insight!

  • Perl: Edit hyperlinks in nested tags that aren't on seperate lines

    - by user305801
    I have an interesting problem. I wrote the following perl script to recursively loop through a directory and in all html files for img/script/a tags do the following: Convert the entire url to lowercase Replace spaces and %20 with underscores The script works great except when an image tag in wrapped with an anchor tag. Is there a way to modify the current script to also be able to manipulate the links for nested tags that are not on separate lines? Basically if I have <a href="..."><img src="..."></a> the script will only change the link in the anchor tag but skip the img tag. #!/usr/bin/perl use File::Find; $input="/var/www/tecnew/"; sub process { if (-T and m/.+\.(htm|html)/i) { #print "htm/html: $_\n"; open(FILE,"+<$_") or die "couldn't open file $!\n"; $out = ''; while(<FILE>) { $cur_line = $_; if($cur_line =~ m/<a.*>/i) { print "cur_line (unaltered) $cur_line\n"; $cur_line =~ /(^.* href=\")(.+?)(\".*$)/i; $beg = $1; $link = html_clean($2); $end = $3; $cur_line = $beg.$link.$end; print "cur_line (altered) $cur_line\n"; } if($cur_line =~ m/(<img.*>|<script.*>)/i) { print "cur_line (unaltered) $cur_line\n"; $cur_line =~ /(^.* src=\")(.+?)(\".*$)/i; $beg = $1; $link = html_clean($2); $end = $3; $cur_line = $beg.$link.$end; print "cur_line (altered) $cur_line\n"; } $out .= $cur_line; } seek(FILE, 0, 0) or die "can't seek to start of file: $!"; print FILE $out or die "can't print to file: $1"; truncate(FILE, tell(FILE)) or die "can't truncate file: $!"; close(FILE) or die "can't close file: $!"; } } find(\&process, $input); sub html_clean { my($input_string) = @_; $input_string = lc($input_string); $input_string =~ s/%20|\s/_/g; return $input_string; }

  • Losing reference to $_post variable?

    In the code below, the echo at the top returns true, but the echo at the bottom returns nothing.

  • Different positions in ViewPager

    - by Kalai Selvan.G
    In my Application am using ViewPager to swipe the images,which comes through webservice as URL. Everything goes smoothly,the problem is while swiping myself getting the position as collapsed one.. Swipe left-right: positions are 1,2,3,4,5,etc.. if i stops swiping at 5th pos and started to Swipe from right-left: positions are 2,1...why this happens? I need to catch the position of the imageURL to find out the ID of the specific image and so i need to download and set it as wallpaper.. Normally while we swipe from right-left,the positions should decrease like 4,3,2,1. Also in debugger mode i got some start position,end position,last position with different values.. Any Clue about ViewPager. Here is my code: public class ImagePagerActivity extends BaseActivity { private ViewPager pager; private DisplayImageOptions options; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.ac_image_pager); Bundle bundle = getIntent().getExtras(); String[] imageUrls = bundle.getStringArray(Extra.IMAGES); int pagerPosition = bundle.getInt(Extra.IMAGE_POSITION, 0); options = new DisplayImageOptions.Builder() .showImageForEmptyUrl(R.drawable.image_for_empty_url) .cacheOnDisc() .decodingType(DecodingType.MEMORY_SAVING) .build(); pager = (ViewPager) findViewById(R.id.pager); pager.setAdapter(new ImagePagerAdapter(imageUrls)); pager.setCurrentItem(pagerPosition); } private class ImagePagerAdapter extends PagerAdapter { private String[] images; private LayoutInflater inflater; ImagePagerAdapter(String[] images) { this.images = images; inflater = getLayoutInflater(); } @Override public void destroyItem(View container, int position, Object object) { ((ViewPager) container).removeView((View) object); } @Override public void finishUpdate(View container) { } @Override public int getCount() { return images.length; } @Override public Object instantiateItem(View view, int position) { final FrameLayout imageLayout = (FrameLayout) inflater.inflate(R.layout.item_pager_image, null); final ImageView imageView = (ImageView) imageLayout.findViewById(R.id.image); final ProgressBar spinner = (ProgressBar) imageLayout.findViewById(R.id.loading); imageLoader.displayImage(images[position], imageView, options, new ImageLoadingListener() { public void onLoadingStarted() { spinner.setVisibility(View.VISIBLE); } public void onLoadingFailed() { spinner.setVisibility(View.GONE); imageView.setImageResource(android.R.drawable.ic_delete); } public void onLoadingComplete() { spinner.setVisibility(View.GONE); } }); ((ViewPager) view).addView(imageLayout, 0); return imageLayout; } @Override public boolean isViewFromObject(View view, Object object) { return view.equals(object); } @Override public void restoreState(Parcelable state, ClassLoader loader) { } @Override public Parcelable saveState() { return null; } @Override public void startUpdate(View container) { } } }

  • IE8 rendering of local-files is wrong

    - by Eric
    It appears that IE8 is not rendering properly a local file: Consider this simple webpage: http://sayang.free.fr/ie8render.html (html code below) extracted from a w3c tutorial on opacity. Save it locally and display it again: the local file has no opacity! That's very annoying, especially when one wants to design complex pages on prototypes placed in local files. Do you have a solution to that ? <html> <head> <title>IE8 Local File</title> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> <meta http-equiv="pragma" content="no-cache" /> <meta http-equiv="cache-control" content="no-cache" /> <meta http-equiv="expires" content="-1" /> <style type="text/css"> div.background { width: 500px; height: 250px; background: url(http://www.w3schools.com/css/klematis.jpg) repeat; border: 2px solid black; } div.transbox { width: 400px; height: 180px; margin: 30px 50px; background-color: #ffffff; border: 1px solid black; /* for IE */ filter:alpha(opacity=60); /* CSS3 standard */ opacity:0.6; } div.transbox p { margin: 30px 40px; font-weight: bold; color: #000000; } </style> </head> <body> <h2>Save this file locally and open it to see the difference</h2> <div class="background"> <div class="transbox"> <p>This is some text that is placed in the transparent box.

  • Menu floating to the right on IE and to the left in FF

    - by the_drow
    I am working on a website that has a menu which behaves correctly on FF but not on IE (as usuall). On IE it floats to the right while it should float to the left, however if float is set to none it behaves almost correctly, attaching the onto the top of the container. Here's the css: #navigation_wrap { background: url(../images/ltr/nav_bg.png); height: 34px; width: 954px; } .btn_login { float: right; margin: 4px 4px 0 0; } .navigation { float: left; } .navigation ul { list-style: none; margin: 8px 0 0 15px; } .navigation ul li { border-right: 1px solid white; float: left; padding: 0 12px 0 12px; } .navigation ul li.last { border: none; } .navigation ul li a { color: white; font-size: 14px; text-decoration: none; } .navigation ul li a:hover { text-decoration: underline; } .navigation ul li a.active { font-weight: bold; } And here's the html: <div id="navigation_wrap"> <div class="navigation"> <ul> <li><a class="active" href="default.asp">Home Page</a></li> <li><a class="" href="faq.asp">FAQ</a></li><li><a class="" href="articles.asp">Articles</a></li> <li><a class="" href="products.asp">Packages &amp; Pricing</a></li> <li><a class="" href="gp.asp?gpid=15">test1</a></li> <li><a class=" last" href="gp.asp?gpid=17">test asher</a></li> </ul> </div> <div class="btn_login"> ... </div> </div> I hope anyone would have an idea.

  • Which MarkDown (WMD) javascript editor should I use?

    - by Edan Maor
    Background I'm working on an application which requires user-entered content, and I've decided to use a StackOverflow-style MarkDown editor. After researching this topic for the last few days, I realize there are numerous forks of the base WMD editor, some with a few basic enhancements and some with serious differences from the StackOverflow one. Since this will be the heart of the application, I'd like to start with the best code base I can. I'd be happy if anyone can recommend which one of the many solutions out there best fits my needs. Below is requirements, plus what I've managed to find already. I'm hoping this question will help me decide which version to go with, and maybe help me discover a port out there that's an even better fit for my needs. The requirements for my project Live Preview Multiple editors on the same page (not know how many in advance, since the user can dynamically add another editing box). Ability to extend with extra buttons (I'd like a button to upload a picture, instead of just adding an img url). Ability to dynamically show/hide the edit box (and only see the preview box). Not an absolute must, but I'd prefer to stick as close to StackOverflow's look and feel, since it's well known. Don't know if this matters, but the backend is written in Django. Editors I've looked at Here are a few of the code bases I've looked at, with thoughts. Obviously, I might be missing another solution out there. The derobins version. From what I can tell, this is the official StackOverflow version. Seems like it doesn't support multiple editors on one page. JQuery.MarkEdit. Looks very good, but is pretty different from the StackOverflow version. MooWMD. Looks like the winner right now, but I'm a little concerned since it looks less active/hackable than MarkEdit. The wmd-new version. Not sure, looks like an old codebase without much use. The SocialSite branch. Seems like it's not for public use.

  • How can I tell groovy/grails not to try to "re-encode" binary data? (Revised title)

    - by ?????
    I have a groovy/grails application that needs to serve images It works fine on my dev box, the image is returned properly. Here's the start of the returned JPEG, as seen by od -cx 0000000 377 330 377 340 \0 020 J F I F \0 001 001 001 001 , d8ff e0ff 1000 464a 4649 0100 0101 2c01 but on the production box, there's some garbage in front, and the d8ff e0ff before the 1000 is missing 0000000 ? ** ** ? ** ** ? ** ** ? ** ** \0 020 J F bfef efbd bdbf bfef efbd bdbf 1000 464a 0000020 I F \0 001 001 001 \0 H \0 H \0 \0 ? ** ** ? 4649 0100 0101 4800 4800 0000 bfef efbd It's the exact same code. I just moved the .war over and run it on a different machine. (Isn't Java supposed to be write once, run everywhere?) Any ideas? An "encoding" problem? The code is sent to the response like this: response.contentType = "image/jpeg"; response.outputStream << out; Here's the code that locates the image on an internal application server and re-serves the image. I've pared down the code a bit to remove the error handling, etc, to make it easier to read. def show = { def address = "http://internal.application.server:9899/img?photoid=${params.id}" def out = new ByteArrayOutputStream() out << new URL(address).openStream() response.contentLength = out.size(); // XXX If you don't do this hack, "head" requests won't work! if (request.method == 'HEAD') { render( text : "", contentType : "image/jpeg" ); } else { response.contentType = "image/jpeg"; response.outputStream << out; } } Update: I tried setting the CharacterEncoding response.setCharacterEncoding("ISO-8859-1"); if (request.method == 'HEAD') { render( text : "", contentType : "image/jpeg" ); } else { response.contentType = "image/jpeg;charset=ISO-8859-1"; response.outputStream << out; } but it made no difference in the output. On my production machine, the binary bytes in the image are re-encoded/escaped as if they were UTF-8 (see Michael's explanation below). It works fine on my development machine.
