  • Detect mouseover and show tooltip text for dots on an HTML Canvas

    - by carl asquith
    Ive recently created a "map" although not very sophisticated (im working on it) it has the basic function and is generally heading in the right direction. If you look at it you can see a tiny red dots and on those tiny red dots i want to mouseover it and see text basically but ive had a bit of trouble getting the code right. http://hummingbird2.x10.mx/website%20creation/mainpage.htm This is all the code so far. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Oynx Warrior</title> <link rel="stylesheet" type="text/css" href="mystyle.css" /> </head> <body> <h1>Oynx Warrior</h1> <canvas id="myCanvas" width="500" height="500" style="border:1px solid #c3c3c3;"> Your browser does not support the canvas element. </canvas> <script type="text/javascript"> var c=document.getElementById("myCanvas"); var cxt=c.getContext("2d"); cxt.fillStyle="#red"; cxt.beginPath(); cxt.arc(50,50,1,0,Math.PI*2,true); cxt.closePath(); cxt.fill(); </script> </body> </html>

  • How can I use CssResources in UiBinder a generated Cell?

    - by confile
    I want to generate a Cell for a CellWidget with the UiBinder (UiRenderer). What I did to generate the cell is in MyCell.java: public class MyCell implements AbstractCell<MyDto> { public interface Resources extends ClientBundle { @Source({Css.DEFAULT_CSS }) Css css(); } public interface Css extends CssResource { String DEFAULT_CSS = "test/MyStyle.css"; String test(); } interface MyUiRenderer extends UiRenderer { void render(SafeHtmlBuilder sb, String name, SafeStyles styles); } private static MyUiRenderer renderer = GWT.create(MyUiRenderer.class); Resources resources = GWT.create(Resources.class); @Override public void render(SafeHtmlBuilder safeHtmlBuilder, MyDto model) { SafeStyles style = SafeStylesUtils.fromTrustedString(resources.css().test().toString()); renderer.render(safeHtmlBuilder, model.getName(), style); } } My MyCell.ui.xml file looks like this: <!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent"> <ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'> <ui:with field="name" type="java.lang.String" /> <ui:with field='styles' type='com.google.gwt.safecss.shared.SafeStyles'/> <div style="{styles}"><ui:text from="{name}" /></div> </ui:UiBinder> MyStyle.css: .test { background-color: red; font-size: 20px; display: flex; ... } When I run my code I get the following error: [DEBUG] [mobile] - Rebinding test.client.app.MyCell.MyUiRenderer [DEBUG] [mobile] - Invoking generator com.google.gwt.uibinder.rebind.UiBinderGenerator [ERROR] [mobile] - java.lang.String required, but {styles} returns com.google.gwt.safecss.shared.SafeStyles: <div style='{styles}'> (:9) [ERROR] [mobile] - Deferred binding failed for 'test.client.app.MyCell.MyUiRenderer'; expect subsequent failures [ERROR] [mobile] - (GWT.java:72) 2014-06-08 17:15:05,214 [FATAL] Uncaught Exception: Then I tried to this: in my UiBinder but it does not work.

  • Google Maps + PODSCMS

    - by Sharath
    Hi, I have a column called 'location' in a POD which I have created. I was looking to write a input helper where I display a Google Map and the user clicks on a location, and I capture that into this column. This is what I am trying to do <div class="form pick <?php echo $location; ?>"> <script src="http://maps.google.com/maps?file=api&v=1&key=<key_here>" type="text/javascript"></script> <div id="map" style="width:500; height:500"> <script type="text/javascript"> map=new GMap(document.getElementById("map")); map.centerAndZoom(new GPoint(77.595062,13.043359),6); map.setUIToDefault(); </script> </div> </div> But I am getting a number of errors from google maps API. Any idea how i can get this helper in there?

  • Youtube Javascript API play(); not working.. what am I doing wrong?

    - by odpogn
    Hello, I'm playing around with YouTubes Javascript API. I've set up a test page on my local enviornment, but the play function is not working. The video loads, and I can press play on the yt video screen, but my link "play" isn't working. Can someone tell me what I'm doing wrong?? I've been following this: http://code.google.com/apis/youtube/js_api_reference.html <html> <head> <script type="text/javascript" src="public/javascripts/swfobject.js"></script> </head> <body> <div id="ytapiplayer"> You will need Flash 8 or better to view this content. </div> <script type="text/javascript"> var params = { allowScriptAccess: "always" }; var atts = { id: "myytplayer" }; swfobject.embedSWF("http://www.youtube.com/v/OQSNhk5ICTI&enablejsapi=1&playerapiid=ytplayer", "ytapiplayer", "425", "365", "8", null, null, params, atts); function onYouTubePlayerReady(playerId) { ytplayer = document.getElementById("myytplayer"); } function play() { if (ytplayer) { ytplayer.playVideo(); } } </script> <a href="javascript:void(0);" onclick="play();">Play</a> </body> </html>

  • Why is my long polling code for a notification system not updating in real time? PHP MYSQL

    - by tjones
    I am making a notification system similar to the red notification on facebook. It should update the number of messages sent to a user in real time. When the message MYSQL table is updated, it should instantly notify the user, but it does not. There does not seem to be an error inserting into MYSQL because on page refresh the notifications update just fine. I am essentially using code from this video tutorial: http://www.screenr.com/SNH (which updates in realtime if a data.txt file is changed, but it is not written for MYSQL like I am trying to do) Is there something wrong with the below code: **Javascript** <script type="text/javascript"> $(document).ready(function(){ var timestamp = null; function waitForMsg(){ $.ajax({ type: "GET", url: "getData.php", data: "userid=" + userid, async: true, cache: false, success: function(data){ var json = eval('(' + data + ')'); if (json['msg'] != "") { $('.notification').fadeIn().html(json['msg']); } setTimeout('waitForMsg()',30000); }, error: function(XMLHttpRequest, textStatus, errorThrown){ setTimeout('waitForMsg()',30000); } }); } waitForMsg(); </script> <body> <div class="notification"></div> **PHP*** <?php if ($_SERVER['REQUEST_METHOD'] == 'GET' ) { $userid = $_GET['userid']; include("config.php"); $sql="SELECT MAX(time) FROM notification WHERE userid='$userid'"; $result = mysql_query($sql); $row = mysql_fetch_assoc($result); $currentmodif = $row['MAX(time)']; $s="SELECT MAX(lasttimeread) FROM notificationsRead WHERE submittedby='$userid'"; $r = mysql_query($s); $rows = mysql_fetch_assoc($r); $lasttimeread = $rows['MAX(lasttimeread)']; while ($currentmodif <= $lasttimeread) { usleep(10000); clearstatcache(); $currentmodif = $row['MAX(time)']; } $response = array(); $response['msg'] = You have new messages; echo json_encode($response); } ?>

  • Process data BEFORE a 301 Redirect?

    - by Jesse
    So, I've been working on a PHP link shortener (I know, just what the world needs). Basically when the page loads, php determines where it needs to go and sends a 301 Header to redirect the browser, like so... Header( "HTTP/1.1 301 Moved Permanently" ); header("Location: http://newsite.com"; Now, I'm trying to add some tracking to my redirects and insert some custom analytics data into a MySQL table before the redirect happen. It works perfectly if I don't specify the a redirect type and just use: header("Location: http://newsite.com"; But, of course as soon as you add in the 301 header, nothing else gets processed. Actually, on the first request, it sends the data to MySQL, but on any subsequent requests there's no communication with the database. I assume it's a browser caching issue, once it's seen the 301 it decides they're no reason to parse anything on future requests. But, does anyone know if there's any way to get around this? I'd really like to keep it as a 301 for SEO purposes (I believe if you don't specify it sends a 404 by default?). I thought about using .htaccess to prepend a file to the page that will do the MySQL work, but with the 301, wouldn't that just get ignored as well? Anyway, I'm not sure if there's any solution other than using a different type of redirect, but I'm ready to give up just yet. So, any suggestions would be much appreciated. Thanks!

  • button onclick not working

    - by nsw1475
    I have a javascript where I need to hide (and eventually show) some text by clicking a button. However, when I click the button, it does not call the function specified in the onclick parameter, and so nothing happens. Here is my source code: <script type="text/javascript"> $(document).ready(function(){ var tip = 1; $(".tip1").hide(); $(".tip2").hide(); switch (tip) { case 1: $(".tip1").show(); break; case 2: $(".tip2").show(); break; } function nextTip() { $(".tip1").hide(); return; } }); </script> <br/> <div id='bg_container' style='background-image: url("<?=$PICS?>trackingpage_middle.jpg")' > <img style='z-index:-1;' width='737px' src='<?=$PICS?>trackingpage_top.jpg'> <div id='main_container' > <form> <input type="button" onClick="nextTip()" value = "Next Tip" /> </form> <div class="tip1"> ... and so on.

  • Problem setting dynamic UITableViewCell height

    - by HiveHicks
    I've got a UITableView with two dynamic rows. Each of the rows is a subclass of UITableViewCell and is loaded from nib. As my rows contain dynamic content, I use layoutSubviews to reposition all subviews: - (void)layoutSubviews { [super layoutSubviews]; CGFloat initialHeight = titleLabel.bounds.size.height; CGSize constraintSize = CGSizeMake(titleLabel.bounds.size.width, MAXFLOAT); CGSize size = [titleLabel.text sizeWithFont:titleLabel.font constrainedToSize:constraintSize]; CGFloat delta = size.height - initialHeight; CGRect titleFrame = titleLabel.frame; titleFrame.size.height += delta; titleLabel.frame = titleFrame; locationLabel.frame = CGRectOffset(locationLabel.frame, 0, delta); dayLabel.frame = CGRectOffset(dayLabel.frame, 0, delta); timeLabel.frame = CGRectOffset(timeLabel.frame, 0, delta); } The problem is that I can't find a way to determine the height in table view delegate's tableView:heightForRowAtIndexPath: method. The trick is that I load cell from nib, so just after it's loaded titleLabel.bounds.size.width is 300 px (as in nib), not taking into account type of the device (iPhone/iPad) and current orientation, so it seems impossible to calculate the height without conditional checks for orientation and device type. Any ideas?

  • Drupal 6: creating different profiles to list at custom page adding page and selecting as many as i

    - by artmania
    Hi friends, I'm a newbie drupal... I'm working on my first Drupal project. I need to make an events page for some conferences. I create event content type, and creating fields like date-place-title-etc with CCK. There are also speakers, can be up to 20. each speaker has photo-namesurname-position. same speaker can be added to more than 1 event. So it is silly to create 60 fields (photo-name-position) for 20 speakers at event adding page. and expecting admin to fill all for an event adding action. there must be a way to create speakers additionally, and listing them at event adding page with checkboxes. and admin just select the speakers from the list, can be 1 or 20 speaker. how can create such thing? in what type should I create these speakers, so i can list them in event adding page for admin to select as many as he wants. Appreciate helps so much!! thanks a lot!

  • Use CSS3 nth-child to alternate the float of images within DIV tags...

    - by Aaron Rodgers
    Basically, what I'm trying to create is a page of div tags, each has an image inside them and I'm trying to use CSS3's nth-child to alternate the float of that specific image. But for the life of me, I can't get the nth-child to locate those images. Here is my code so far... CSS .featureBlock img:nth-of-type(even) { float: left; } .featureBlock img:nth-of-type(odd) { float: right; } This is the HTML of one of those div tags.... <div class="featureBlock"> <h1>Multisize Players</h1> <div class="featureHelpBlock"><a href="#">More help with this</a></div> <img src="http://office2.vzaar.com/images/features/ft_multisize_players.png"> <span class="featureContent"><p>A variety of player sizes is important as we recognise the fact that no two videos or websites are ever the same and you will want something that suits your site&#8217;s look.

  • javascript not firing when asp.net user control loads

    - by Jawahar
    I am trying to fire a Javascript call when an ASP.net user control to an aspx page. The Web site allows users to add user controls to a page (similar to adding a widget etc to a page like google widgets). But when the control is added the javascript does not fire, only if the page is refreshed will it fire the javascript. IF the next time the website is accessd and the controlis still there the javascript fires too. Do I need to use the RegisterClientScript method to register the call (setAutoTimer()) on the control load or OnPreRender event. In the User control I have this at the start of the ascx file: <script language="javascript" type="text/javascript"> $(document).ready(function () { if ($("#alarmList").length) { setAutoTimer(); getData(); } }); function setAutoTimer() { setInterval(getData, 10000); } function getData() { $.ajax({ type: "POST", url: "Service.asmx/getListData data: "{'inverterid': '" + "1'}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { AjaxSucceeded(msg); }, error: AjaxFailed }); } function AjaxSucceeded(result) { $("#alarmList").empty(); $("#alarmsListTemplate").tmpl(result.d) .appendTo("#alarmList"); } function AjaxFailed(result) { alert(result.status + ' ' + result.statusText); } </script>

  • How can I theme custom form(drupal 6.x)

    - by Andrew
    DRUPAL 6.X I have this custom form constructor inside my custom module which is invoke through ajax request. I’m attempting to theme this form with the template file reside in my theme directory. For that matter, I’ve registered my theme inside template.php file which reside in my theme folder. Here’s how this file looks – function my_theme() { return array( 'searchdb' => array( 'arguments' => array('form' => NULL), 'template' => 'searchform', ) ); } And the following is the excerpt of module code – function test_menu() { $my_form['searchdb'] = array( 'title' => 'Search db', 'page callback' => 'get_form', 'page arguments' => array(0), 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, ); return $my_form; } function get_form($formtype){ switch($formtype){ case 'searchdb' : echo drupal_get_form('searchdb'); break; } } function searchdb(){ $form['customer_name'] = array( '#type' => 'textfield', '#title' => t('Customer Name'), '#size' => 50, '#attributes' => array('class' => 'name-textbox'), ); return $form; } As you can imagine, this is not working at all. Just to test if my theme is even registered, I’ve also tested with theme function but, it’s not called. I've checked template file name and form-id(through the outputted html source) and everything seems ok. I would be glad if anyone could point me to the right direction.

  • XML parsing problem

    - by Albinoswordfish
    I'm having this strange XML parsing problem. I have this XML string I'm trying to parse <?xml version="1.0"?> <response status="success"> <lot>32342</lot> </response> I'm using XPath with Java in order to do this. I'm using the Xpath expression "/response/@status" to find the text "success". However whenever I evaluate this expression I get an empty string. However I am able to successfully parse this string using "/response/@type" <?xml version="1.0"?> <response type="success"> <lot>32342</lot> </response> So why would simply changing the name of the attribute change the return string to nothing? is = new InputSource(testWOcreateStrGood); xPathexpressionSuccess = xPath.compile("/response/@status"); responseStr = xPathexpressionSuccess.evaluate(is); reponseStr is the string I posted earlier with the "status" attribute

When I print out the values in that vector for the second one, it has the move in it from the first one along with the move from the second one. Can anyone tell me why it seems to be assigning by reference and not value? Are vector assignments copied by value or by reference in Google's Go language? package main import "fmt" import "container/vector" type Move struct { x0, y0, x1, y1 int } type PegPuzzle struct { movesAlreadyDone * vector.Vector; } func (p *PegPuzzle) InitPegPuzzle(){ p.movesAlreadyDone = vector.New(0); } func NewChildPegPuzzle(parent *PegPuzzle) *PegPuzzle{ retVal := new(PegPuzzle); retVal.movesAlreadyDone = parent.movesAlreadyDone; return retVal } func (p *PegPuzzle) doMove(move Move){ p.movesAlreadyDone.Push(move); } func (p *PegPuzzle) printPuzzleInfo(){ fmt.Printf("-----------START----------------------\n"); fmt.Printf("moves already done: %v\n", p.movesAlreadyDone); fmt.Printf("------------END-----------------------\n"); } func main() { p := new(PegPuzzle); cp1 := new(PegPuzzle); cp2 := new(PegPuzzle); p.InitPegPuzzle(); cp1 = NewChildPegPuzzle(p); cp1.doMove(Move{1,1,2,3}); cp1.printPuzzleInfo(); cp2 = NewChildPegPuzzle(p); cp2.doMove(Move{3,2,5,1}); cp2.printPuzzleInfo(); } Any help will be greatly appreciated. Thanks!

  • photo upload with codeigniter

    I know there are many tutorials online, but I could not make them work :( maybe something particularly wrong with my system :/ My Controller localpath is: /localhost/rl/applications/backend/controller/ Controller: function do_upload() { $config['upload_path'] = './uploads/'; $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = '100'; $config['max_width'] = '1024'; $config['max_height'] = '768'; $this->load->library('upload', $config); if ( ! $this->upload->do_upload()) { $error = array('error' => $this->upload->display_errors()); $this->load->view('add_image', $error); } else { $data = array('upload_data' => $this->upload->data()); $data['id'] = $this->input->post['id_work']; $this->load->view('add_image', $data); } } My View localpath is: /localhost/rl/applications/backend/view/ View: echo form_open_multipart('do_upload'); <ul class="frm"> <li><label>File: *</label><input type="file" name="userfile" class="frmlmnt" size="50" /></li> <li><label></label><input type="submit" class="btn" value="Upload" /></li> </ul> </form> Maybe I do something wrong with path

  • Return multiple IDs from a function and use the result in a query

    - by NewK
    I have this function that returns me all children of a tree node: CREATE OR REPLACE FUNCTION fn_category_get_childs_v2(id_pai integer) RETURNS integer[] AS $BODY$ DECLARE ids_filhos integer array; BEGIN SELECT array ( SELECT category_id FROM category WHERE category_id IN ( (WITH RECURSIVE parent AS ( SELECT category_id , parent_id from category WHERE category_id = id_pai UNION ALL SELECT t.category_id , t.parent_id FROM parent INNER JOIN category t ON parent.category_id = t.parent_id ) SELECT category_id FROM parent WHERE category_id <> id_pai ) ) ) into ids_filhos; return ids_filhos; END; and I would like to use it in a select statement like this: select * from teste1_elements where category_id in (select * from fn_category_get_childs_v2(12)) I've also tried this way with the same result: select * from teste1_elements where category_id=any(select * from fn_category_get_childs_v2(12))) But I get the following error: ERROR: operator does not exist: integer = integer[] LINE 1: select * from teste1_elements where category_id in (select *... ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. The function returns an integer array, is that the problem? SELECT * from fn_category_get_childs_v2(12) retrieves the following array (integer[]): '{30,32,34,20,19,18,17,16,15,14}'
