  • Java split giving opposite order of arabic characters

    - by MuhammadA
    I am splitting the following string using \\| in java (android) using the IntelliJ 12 IDE. Everything is fine except the last part, somehow the split picks them up in the opposite order : As you can see the real positioning 34,35,36 is correct and according to the string, but when it gets picked out into split part no 5 its in the wrong order, 36,35,34 ... Any way I can get them to be in the right order? My Code: public ArrayList<Book> getBooksFromDatFile(Context context, String fileName) { ArrayList<Book> books = new ArrayList<Book>(); try { // load csv from assets InputStream is = context.getAssets().open(fileName); try { BufferedReader reader = new BufferedReader(new InputStreamReader(is)); String line; while ((line = reader.readLine()) != null) { String[] RowData = line.split("\\|"); books.add(new Book(RowData[0], RowData[1], RowData[2], RowData[3], RowData[4], RowData[5])); } } catch (IOException ex) { Log.e(TAG, "Error parsing csv file!"); } finally { try { is.close(); } catch (IOException e) { Log.e(TAG, "Error closing input stream!"); } } } catch (IOException ex) { Log.e(TAG, "Error reading .dat file from assets!"); } return books; }

  • Accessing XML file using JavaScript And ASP.net |VB code

    - by Bubba
    Am trying to read in data from an xml file but using javascript which is embedded into my asp.net|vb code. I am new to asp.net but coming from a programming background. so I declared the xml objects for the appropriate browsers, as well as the name of the local xml to read data from, I then start by appending the create the table tag and then append it to the div tag in hack5.aspx I declare the variable that will represent/ hold the xml returned data object. I then run a for loop , before creating a row tag and then appending it to the div tag in hack5.aspx I then create the a row tag and then appending it to the div tag in hack5.aspx | then create a TextNode which is passed to variable, then create a td and append to div . then lastly append the textnode to td this format is the same for creating another 13 td tags that are to hold the data. The main problem is when I run the script - I see nothing display on my screen . no errors are shown, but with your sample code runs smoothly. So the first file hack5.aspx is as follows: <%@ Page Language="VB" AutoEventWireup="false" CodeFile="hack5.aspx.vb" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Diplaying MessageBox from ASP.NET</title> </head> <body> <form id="form1" runat="server"> <div id="showtime" > </div> </form> </body> </html> The next file hack5.aspx.vb is as follows: Partial Class _Default Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim scriptString as String = "<script language=JavaScript> if (window.XMLHttpRequest) " scriptString += " { " scriptString += " xhttp=new XMLHttpRequest();

  • I can't upload mp3 files using Codeigniter

    - by Drew
    There are lots of suggested fixes for this but none of them work for me. I have tried making the upload class (using the following methods: http://codeigniter.com/forums/viewthread/148605/ and http://codeigniter.com/forums/viewthread/125441/). When i try to upload an mp3 i get the error message "The filetype you are attempting to upload is not allowed". Below is my code for my model and my form (i've got a very skinny controller).

  • how to get the value from a CSS class object in javascript

    - by amit
    I have to select an <a> element from the given class of objects. when i click on the anchor tag in the showcase_URL class, i want the jquery function to get the value from <a> tag. How can this be done? I cannot make this an id as I am running a while loop to construct all the elements in php. there would be multiple objects of this class. there is no definite selector through which I can get the value of the anchor tag. Help would be much appreciated. echo '<div id="content">'; echo '<div class="showcase_data">'; echo '<div class="showcase_HEAD">'.$row->title.'</div>'; echo '<div class="showcase_TYPE">'.$row->type.'</div>'; echo '<div class="showcase_date">&nbsp;&nbsp;'.$row->date.'</div>'; echo '<div class="showcase_THUMB" style="float: left;" ></div>'; echo '<div class="showcase_TEXT">'.$row->details.'</div><br/>'; echo '<div class="showcase_URL"><a class="purl" value='.$row->num.'href="'.$row->url.'">PROJECT URL</a></div>'; echo '</div>'; echo '</div>';

  • How can I distinguish between overlapping segments of text using HTML?

    - by Siracuse
    Easy question, it is valid to have overlapping spans in html? Example: <span id="1">This is <span id="2"> some text </span> some other text </span> ^ ^ End1 End2 Edit: I see now that the spans closing tag would be ambiguous about which one it is closing, and that first </span> would close span id = 2, not 1 like I intended. My problem is, I have a block of text which I'm trying to highlight based on what the mouse hovers over. This block of text is composed of sections, some of which "overlap" eachother. I'm trying to use some jQuery and HTML to present this document so when I hover over the sections, the appropriate one will be highlighted. So, in my example above, the first span is meant to be ended with the first span close tag, and the second span is meant to be ended to with the second span close tag. This is because of the semantics of my document, these are two overlapping segments. I want it so when I hover to the left, it will only highlight up to span id = 1 and the first span close, if I hover between the two "overlapping" spans, it will highlight both of them, and if I hover to the right, it will highlight from span id=2 to the last span close. However, I'm starting to think this isn't possible. Is there any way I can distinguish segments of text in HTML that allows overlapping? So my jQuery script that highlights when I hover over different spans will highlight the correct portions. Should I alternate between div's and spans? Would that disambiguate what I'm closing then and allow me the do the proper highlighting with my jQuery hover script? I'm wondering about more than 2 segments overlapping now. Sigh, I wish I could just be explicate about what I'm closing.

  • How should I progressively enhance this content with JavaScript?

    - by Sean Dunwoody
    The background to this problem is that I'm doing a computing project which involves Some drop down boxes for input, and a text input where the user can input a date. I've used YUI to enhance the form, so the calendar input uses the YUI calendar widget and the drop down list is converted into a horizontal list of inputs where the user only has to click once to select any input as opposed to two clicks with the drop down box (hope that makes sense, not sure how to explain it clearly) The problem is, that in the design section of my project I stated that I would follow the progressive enhancement principles. I am struggling however to ensure that users without JavaScript are able to view the drop down box / text input on said page. This is not because I do not necessarily know how, but the two methods I've tried seem unsatisfactory. Method 1 - I tried using YUI to hide the text box and drop down list, this seemed like the ideal solution however there was quite a noticeable lag when loading the page (especially for the first time), the text box and drop down list where visibile for at least a second. I included the script for this just before the end of the body tag, is there any way that I can run it onload with YUI? Would that help? Method 2 - Use the noscript tag . . . however I am loathed to do this as while it would be a simple solution, I have read various bad things about the noscript tag. Is there a way of making mehtod one work? Or is there a better way of doing this that I am yet to encounter?

  • Use Struct as a Ptr/class? Need a fix .NET

    - by acidzombie24
    I wrote a bunch of code and i would like to fix it the fastest way possible. I'll describe my problem in a easier way. I have apples and oranges, they are both Point and in the list apples, oranges. I create a PictureBox and draw the apple/oranges on screen and move them around and update the Point via Tag. The problem now is since its a struct the tag is a copy so the original elements in the list are not update. So, how do i update them? I consider using Point? But those seem to be readonly. So the only solution i can think of is Clear the list, iterate through all the controls then check the picturebox property to check if the image is a apple or orange then add it to a list I really only thought of this solution typing this question, but my main question is, is there a better way? Is there some List<Ptr<Point>> class i can use so when i update the apples or oranges through the tag the element in the list will update as a class would?

  • Problems uploading different file types in codeigniter

    Below is my script that i'm using to upload different files. All the solutions I've found deal only with multiple image uploads. I am totally stumped for a solution on this.

  • Why am I getting "Message sent to deallocated object" in Objective-C?

    - by Dave C
    I have several buttons on my app that are being created dynamically. They are all pointed at the button click event when pressed. When the button pressed method is called, the sender's tag (int value) is parsed into the controller's house ID. It works with one of the buttons — the first one created, to be specific — but the others throw the following error: -[CFNumber intValue]: message sent to deallocated instance 0xc4bb0ff0 I am not releasing these buttons anywhere in my code. I haven't set them to autorelease or anything like that. I'm just wondering why they are doing this on the click. The button click event: - (IBAction) ButtonClick: (id) sender { HouseholdViewController *controller = [[HouseholdViewController alloc] initWithNibName:@"HouseholdViewController" bundle:nil]; controller.delegate = self; controller.HouseID = [(NSInteger)[(UIButton *)sender tag] intValue]; //this line throws an error controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Where I am creating the buttons: UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(MyLongInScreenCoords, MyLatInScreenCoords, 50, 50); UIImage *buttonImageNormal = [UIImage imageNamed:@"blue_pin.png"]; UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:50 topCapHeight:50]; [button setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal]; [self.view addSubview:button]; button.tag = [NSNumber numberWithInt:[[words objectAtIndex: i] intValue]]; ButtonPoints[CurrentHouseCount][0] = button; ButtonPoints[CurrentHouseCount][1] = [NSValue valueWithCGPoint:CGPointMake(MyActualLat, MyActualLong)]; [button addTarget:self action:@selector(ButtonClick:) forControlEvents:UIControlEventTouchUpInside]; CurrentHouseCount++;

  • commitAnimations is not resizing my UIImageView subview

    - by AaronG
    I have created a UIView as a subview and to that subview I have added a UIImageView as a subview. UIView *viewCreated; UIButton *buttonCreated; UIImageView *imageViewCreated; CGRect myFrame = CGRectMake(0, 0, 1024, 1024); viewCreated = [[UIView alloc] initWithFrame:myFrame]; [viewCreated setTag:intTag]; viewCreated.backgroundColor = [UIColor redColor]; [self.view addSubview:viewCreated]; [self randomize]; UIImage *d1Image = [UIImage imageNamed:[NSString stringWithFormat:@"image%d.png", randomNumber]]; imageViewCreated = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f,0.0f,1024.0f, 1024.0f)]; [imageViewCreated setImage:[UIImage imageNamed:[NSString stringWithFormat:@"image%d.png", randomNumber]]]; [viewCreated addSubview:imageViewCreated]; //[imageViewCreated release]; return [viewCreated autorelease]; But when this code executes only the first subview is animated and resized. The UiimageView moves 200 pixels to the left but does not get resized. NSLog(@"sender tag %i",[sender tag]); UIView *currentView = [self.view viewWithTag:[sender tag]]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.5]; currentView.frame = CGRectMake(-200, 0,40, 102); [UIView commitAnimations]; I am pretty sure am I not creating the subviews correctly programmatically, because when I do it in Interface Builder it works as expected. Do I have to do something specific to actually attach the behavior of the second subview to the first subview?

  • JQuery get attr value from ajax loaded page

    In my index.php I've a ajax pager that load a content page (paginator.php). index.php <script type='text/javascript' src='js/jquery-1.11.1.min.js'></script> <script type='text/javascript' src='js/paginator.js'></script> <script type='text/javascript' src='js/functions.js'></script> <!-- Add fancyBox --> <script type="text/javascript" src="js/jquery.fancybox.pack.js?v=2.1.5"></script> <html> <div id="content"></div> paginator.js $(function() { var pageurl = 'paginator.php'; //Initialise the table at the first run $( '#content' ).load( pageurl, { pag: 1 }, function() { //animation(); }); //Page navigation click $( document ).on( 'click', 'li.goto', function() { //Get the id of clicked li var pageNum = $( this ).attr( 'id' ); $( '#content' ).load( pageurl, { pag: pageNum }, function() { //animation(); }); }); }); /* END */ paginator.php <ul><li>..etc </ul> ... ... <a id='test' vid='123'>get the id</a> <a id='test2' url='somepage.php'>open fancybox</a> I would like to take a variable of the loaded page (paginator.php) in this way but unfortunately I can not. functions.js $(function() { $('#test' ).click(function(e) { var id = $('#test').attr('vid'); alert ("vid is " + vid); }); }); /* END */ In this case popup not appear. I tried with add fancybox in my functions.js. Dialog box appear but the url attr is not taken. var url = $('#test2').attr('url'); $('#test').fancybox({ 'href' : url, 'width' : 100, 'height' : 100, 'autoScale' : false, 'transitionIn' : 'none', 'transitionOut' : 'none', 'type' : 'iframe', 'fitToView' : true, 'autoSize' : false }); In other scenarios, without having the page loaded, I can do it, but in this case the behavior is different. How could I do this? thanks EDIT my goal is to open a dialog (fancybox) taking a variable from the loaded page EDIT2 I tried in this way paginator.php <a id="test" vid="1234">click me</a> paginator.js //Initialise the table at the first run $( '#content' ).load( pageurl, { pag: 1 }, function() { hide_anim(); popup(); }); //Page navigation click $( document ).on( 'click', 'li.goto', function() { //Get the id of clicked li var pageNum = $( this ).attr( 'id' ); $( '#content' ).load( pageurl, { pag: pageNum }, function() { hide_anim(); popup(); }); }) function.js function popup() { $('#test' ).click(function(e) { e.preventDefault(); var vid = $('#test').attr('vid'); alert ("vid is " + vid); }); } But popup not appear...

  • SQL placeholder in WHERE IN issue, inserted strings fail.

    - by Alastair Pitts
    As part of my jobs, I need to writes SQL queries to connect to our PI database. To generate a query, I need to pass an array of tags (essentially primary keys), but these have to be inserted as strings. As this will be a modular query and used for multiple tags, a placeholder is being used. The query relies upon the use of the WHERE IN statement, which is where the placeholder is, like below: SELECT SUM(value * 5/1000) as "Hourly Flow [kL]" from piarchive..pitotal WHERE tag IN (?) AND time between ? and ? and timestep = '1d' and calcbasis = 'Eventweighted' and value <> '' The issue is the format in which the tags are to be passed in as. If I add them directly into the query (for testing), they go in the format (these are example numbers): '000000012','00000032','005050236','4560236' and the query looks like: SELECT SUM(value * 5/1000) as "Hourly Flow [kL]" from piarchive..pitotal WHERE tag IN ('000000012','00000032','005050236','4560236') AND time between ? and ? and timestep = '1d' and calcbasis = 'Eventweighted' and value <> '' which works. If I try and add the same tags into the placeholder, the query fails. If I only add 1 tag, with no quotes (using the placeholder), the query works. Why is this happening? Is there anyway around it?

  • Converted PowerBuilder to ASP.Net browsing Errors

    - by user493325
    I had a powerbuilder application which i converted to web application in the format of ASP.Net (aspx) files. after deploying and publishing the converted web application (copy it and add ASP.Net and network Service AND IUser permissions to enable users to access it) in IIS V6.0 over Windows server 2003 and The ASP.Net version is 2.0 The error messages I get when I browse default.aspx web page are as the following:- Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

  • XSLT creating a table with varying amount of columns

    - by H4mm3rHead
    Hi, I have a RSS feed i need to display in a table (its clothes from a webshop system). The images in the RSS vary in width and height and I want to make a table that shows them all. First off i would be happy just to show all of the items in 3 columns, but further down the road i need to be able to specify through a parameter the amount of columns in my table. I run into a problem showing the tr tag, and making it right, this is my Code so far: <xsl:template match="item"> <xsl:choose> <xsl:when test="position() mod 3 = 0 or position()=1"> <tr> <td> <xsl:value-of select="title"/> </td> </tr> </xsl:when> <xsl:otherwise> <td> <xsl:value-of select="title"/> </td> </xsl:otherwise> </xsl:choose> </xsl:template> In RSS all "item" tags are on the same level in the xml, and thus far i need only the title shows. Thr problem seems to be that i need to specify the start tag as well as the end tag of the tr element, and cant get all 3 elements into it, anyone know how to do this?

  • JSP: How can I still get the code on my error page to run, even if I can't display it?

    - by Josh Hinman
    I've defined an error-page in my web.xml: <error-page> <exception-type>java.lang.Exception</exception-type> <location>/error.jsp</location> </error-page> In that error page, I have a custom tag that I created. The tag handler for this tag e-mails me the stacktrace of whatever error occurred. For the most part this works great. Where it doesn't work great is if the output has already begun being sent to the client at the time the error occurs. In that case, we get this: SEVERE: Exception Processing ErrorPage[exceptionType=java.lang.Exception, location=/error.jsp] java.lang.IllegalStateException I believe this error happens because we can't redirect a request to the error page after output has already started. The work-around I've used is to increase the buffer size on particularly large JSP pages. But I'm trying to write a generic error handler that I can apply to existing applications, and I'm not sure it's feasible to go through hundreds of JSP pages making sure their buffers are big enough. Is there a way to still allow my stack trace e-mail code to execute in this case, even if I can't actually display the error page to the client?

  • PHP returning part of the code document

    - by The.Anti.9
    I have a PHP page that does a couple of different things depending on what action is set to in the GET data. Depending, it is supposed to return some JSON, but instead of doing anything it is supposed to it returns the bottom half of the code document itself, starting in the middle of the line. Heres the snippit from where it starts: ... } elseif ($_GET['action'] == 'addtop') { if (!isset($_GET['pname']) || !isset($_GET['url']) || !isset($_GET['artist']) || !isset($_GET['album']) || !isset($_GET['file'])) { die('Error: Incomplete data!'); } if (!file_exists($_GET['pname'].".txt")) { die('Error: No such playlist!'); } $plist = json_decode(file_get_contents($_GET['pname'].".txt"), true); $fh = fopen($_GET['pname'].".txt", 'w') or die('Could not open playlist!'); array_push($plist, array("artist" => $_GET['artist'], "album" => $_GET['album'], "file" => $_GET['file'], "url" => $_GET['url'])); fwrite($fh,json_encode($plist)); } elseif ($_GET['action'] == 'delfromp') { ... And here is what I get when I go to the page: $_GET['artist'], "album" = $_GET['album'], "file" = $_GET['file'], "url" = $_GET['url'])); fwrite($fh,json_encode($plist)); } elseif ($_GET['action'] == 'delfromp') { if (!isset($_GET['pname']) || !isset($_GET['id'])) { die('Error: Incomplete data!'); } if (!file_exists($_GET['pname'].".txt")) { die('Error: No such playlist!'); } $plist = json_decode(file_get_contents($_GET['pname'].".txt"), true); $fh = fopen($_GET['pname'].".txt", 'w') or die('Could not open playlist!'); unset($plist[$_GET['id']]); $plist = array_values($plist); fwrite($fh,json_encode($plist)); } elseif ($_GET['action'] == 'readp') { if (!file_exists($_GET['pname'].".txt")) { die('Error: No such playlist!'); } $plist = json_decode(file_get_contents($_GET['pname'].".txt"), true); $arr = array("entries" = $plist); $json = json_encode($arr); echo $json; } elseif ($_GET['action'] == 'getps') { $plists = array(); if ($handle = opendir('Playlists')) { while (false !== ($playlist = readdir($handle))) { if ($playlist != "." && $playlist != "..") { array_push($plists, substr($playlist, 0, strripos($playlist, '.')-1)); } } } else { die('Error: Can\'T open playlists!'); } $arr = array("entries"=$plists); $json = json_encode($arr); echo $json; } else { die('Error: No such action!'); } ? It starts in the middle of the array_push(... line. I really can't think of what it is doing. Theres no echos anywhere around it. Any ideas?

  • tastypie posting and full example

    - by Justin M
    Is there a full tastypie django example site and setup available for download? I have been wrestling with wrapping my head around it all day. I have the following code. Basically, I have a POST form that is handled with ajax. When I click "submit" on my form and the ajax request runs, the call returns "POST http://192.168.1.110:8000/api/private/client_basic_info/ 404 (NOT FOUND)" I have the URL configured alright, I think. I can access http://192.168.1.110:8000/api/private/client_basic_info/?format=json just fine. Am I missing some settings or making some fundamental errors in my methods?

I want to try updating the entry now. Would that just be appending the pk to the ajax url? For example /api/private/client_basic_info/21/? When I submit that form I get a 501 NOT IMPLEMENTED message. What exactly haven't I implemented? I am subclassing ModelResource, which should have all the ORM-related functions implemented according to the docs.

  • Replacing content with jquery.

    - by BillZ
    I am loading a movie into a overlay. My problem is that when I close the div overlay the movie continues to play. I do not control the code on the move side it is imported via a script tag which then opens in a iframe. I am able to remove the content of the of the div and then the movie stops playing. Then of course when the user opens the div again the movie is gone. My current thinking was that I could simply replace the script tag with one just like it but the outcome of that is that there is nothing there. I have been using jquery. Thanks -- script -- $(document).ready(function() { $("#closeModal2").click(function() { $("#movieContainer").html("<script src='http://www.accelacast.com/programs/launch.js'/>"); }); }); -- html -- <div id="movieContainer"> <script id="movieTag" language='JavaScript' src='http://www.accelacast.com/programs/launch.js'/> </div> On a side note. I tried replacing the src attribute of the script tag with no luck. I was able to replace the src of a image though. Is it not possible to effect the src attribute of script? Thanks

  • Android - Loop Through strings.xml file

Let's say that I have the following format: <!-- FIRST SECTION --> <string name="change_password">Change Password</string> <string name="change_server">Change URL</string> <string name="default_password">password</string> <string name="default_server">http://xxx:8080</string> <string name="default_username">testPhoneAccount</string> <!-- SECOND SECTION --> <string name="debug_settings_category">Debug Settings</string> <string name="reload_data_every_startup_pref">reload_data_every_startup</string> <string name="reload_data_on_first_startup_pref">reload_data_on_first_startup</string> Now let's say I have this: private HashMap<String,Integer> hashmapStringValues = new HashMap<String, Integer>(); Is there a way to iterate only in the second section of my xml file? Maybe wrap the section with a tag like <section2> and then iterate through it? public void initHashMap(){ for (int i=0;i< ???? ;i++) //Here I need to loop only in the second section of my xml file { String nameOfTag = ? // Here I get the name of the tag int value = R.string.nameOfTag // Here I get the associated value of the tag this.hashmapStringValues.put(nameOfTag,value); } }

  • Javascript ended event when video playback ends on android

    - by Tjofras
    I have been trying to create a web page that will redirect the user after he has watched a video (or if he aborted the playback). I've got this working on the iphone but can't really figure out how it works on the android. On the Iphone i have found two ways of doing this. using the tag to embed the quicktime plugin and then adding a event listener with javascript to listen to the 'qt_ended' event. This does obviously not work on android because there is no quicktime plugin. The second thing i tried was using the html5 -tag and listening to the 'ended' event, again this worked on the iphone but to my surprise not on android. In this case i got the video playing on the android phone but no redirect occurred after the video had reached the end. So my guess is that the android browser does not fully support the video-tag and that it does not fire the event. So at this time i don't really know how to proceed. I'm guessing i could do something similar to the quicktime embed solution but using a plugin available on android. But i cant find any information on what plugins is available on the android and if they support some kind of 'ended'-event.

  • Downloading javascript Without Blocking

    - by doug
    The context: My question relates to improving web-page loading performance, and in particular the effect that javascript has on page-loading (resources/elements below the script are blocked from downloading/rendering). This problem is usually avoided/mitigated by placing the scripts at the bottom (eg, just before the tag). The code i am looking at is for web analytics. Placing it at the bottom reduces its accuracy; and because this script has no effect on the page's content, ie, it's not re-writing any part of the page--i want to move it inside the head. Just how to do that without ruining page-loading performance is the crux. From my research, i've found six techniques (w/ support among all or most of the major browsers) for downloading scripts so that they don't block down-page content from loading/rendering: (i) XHR + eval(); (ii) XHR + 'inject'; (iii) download the HTML-wrapped script as in iFrame; (iv) setting the script tag's 'async' flag to 'TRUE' (HTML 5 only); (v) setting the script tag's 'defer' attribute; and (vi) 'Script DOM Element'. It's the last of these i don't understand. The javascript to implement the pattern (vi) is: (function() { var q1 = document.createElement('script'); q1.src = 'http://www.my_site.com/q1.js' document.documentElement.firstChild.appendChild(q1) })(); Seems simple enough: inside this anonymous function, a script element is created, its 'src' element is set to it's location, then the script element is added to the DOM. But while each line is clear, it's still not clear to me how exactly this pattern allows script loading without blocking down-page elements/resources from rendering/loading?

  • UIButton only responds in a small area

    - by Tom Irving
    I'm trying to add a UIButton to a UIView, but am having some trouble with getting it to respond to touches. I have a method which returns UIButtons after I provide it with a tag: - (UIButton*)niceSizeButtonWithTag:(int)tag { UIButton * aButton = [UIButton buttonWithType:UIButtonTypeCustom]; [aButton setTag:tag]; [aButton addTarget:self action:@selector(buttonWasTapped:) forControlEvents:UIControlEventTouchUpInside]; CGRect newFrame = aButton.frame; newFrame.size.width = 44; newFrame.size.height = 44; [aButton setFrame:newFrame]; return aButton; } As you can see I'm creating a new button and increasing the size. I use this in the following way: UIButton * anotherButton = [self niceSizeButtonWithTag:1]; [anotherButton setImage:[UIImage imageNamed:@"image" withExtension:@"png"] forState:UIControlStateNormal]; [anotherButton setCenter:CGPointMake(middleOfView)]; [aView addSubview:anotherButton]; I create a lot of buttons like this, hence the reason for the method. The buttons are always created and added to the subview perfectly. I can see the image and they're in the correct position. The problem is that they only respond to touches in a tiny strip. In this attached image, The yellow shows the whole frame of the button, The red shows the area that will respond to touches. The grey shows a section of the view the button is added to. If anyone could shed some light on why this is happening, it would be really useful.
