  • jQuery 1.4.2 and IE6: change event not firing first time using keyboard

    - by macca1
    I've done a good amount of research on this and found a bunch of reported problems and solutions but the general consensus seems that all change problems in IE6 were fixed in jQuery 1.4.2. I'm having an issue where a change event is not firing in jQuery 1.4.2, but it did fire successfully in jQuery 1.3.2. This is in IE6. I'm about to submit a bug for this, but for my sanity I wanted to post it here first to see if there's something dumb I'm missing. I don't understand why this is working this way... <HTML> <HEAD> <TITLE>jQuery 1.4.2 Problem </TITLE> <script src="jquery-1.4.2.min.js" type="text/javascript"></script> <script> $(document).ready( function() { $("#firstBox").change(function() { alert("CHANGE"); }); // ONLOAD of document autofocus into the first element... $("form").find(":input:visible:first").focus() }); </script> </HEAD> <BODY> <form> <select id="firstBox"> <option value="" selected="selected">--</option> <option value="1">One</option> <option value="2">Two</option> </select> <br><br> <input size="10" id="secondBox"> </form> </BODY> </HTML> Simple enough, right? Onload of the page, give the first element focus. Onchange of the first element, alert. If you use the mouse, it works as expected. The page loads, the focus is in the drop down, you change the option, you get the alert. The problem is if you use the keyboard. The page loads, the focus is in the drop down, you press the down arrow. The option changes. Tab off the field, no alert. Weird. To make it even weirder, if you tab back into the field and change it again (all using the keyboard), the change event DOES fire after tab out this time. Any ideas?

  • iPhone Development: Use POST to submit a form

    I've got the following html form: <form method="post" action="http://shk.ecomd.de/up.php" enctype="multipart/form-data"> <input type="hidden" name="id" value="12345" /> <input type="file" name="pic" /> <input type="submit" /> </form> And the following iPhone SDK Submit method: - (void)sendfile { UIImage *tempImage = [UIImage imageNamed:@"image.jpg"]; NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setHTTPMethod:@"POST"]; [request setURL:[NSURL URLWithString:@"http://url..../form.php"]]; NSString *boundary = @"------------0xKhTmLbOuNdArY"; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; NSMutableData *body = [NSMutableData data]; [body appendData:[[NSString stringWithFormat:@"\r\n%@\r\n",boundary] dataUsingEncoding:NSASCIIStringEncoding]]; [body appendData:[@"Content-Disposition: form-data; name=\"id\"\r\n\r\n" dataUsingEncoding:NSASCIIStringEncoding]]; [body appendData:[@"12345" dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"\r\n%@\r\n",boundary] dataUsingEncoding:NSASCIIStringEncoding]]; [body appendData:[@"Content-Disposition: form-data; name=\"pic\"; filename=\"photo.png\"\r\n" dataUsingEncoding:NSASCIIStringEncoding]]; [body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSASCIIStringEncoding]]; [body appendData:[NSData dataWithData:UIImageJPEGRepresentation(tempImage, 90)]]; [body appendData:[[NSString stringWithFormat:@"\r\n%@",boundary] dataUsingEncoding:NSASCIIStringEncoding]]; // setting the body of the post to the reqeust [request setHTTPBody:body]; NSError *error; NSURLResponse *response; NSData* result = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSString* aStr = [[[NSString alloc] initWithData:result encoding:NSASCIIStringEncoding] autorelease]; NSLog(@"Result: %@", aStr); [request release]; } This does not work, but I have no clue why.

  • Is it poor practice to build an SQL query using WHERE 1=1 AND ...

    - by Rob
    I'm writing a script that builds an SQL query by concatenating the string and adding conditions to the WHERE clause as needed. Would it be better practice to use WHERE 1=1 so that the first condition is satisfied and the script can just concatenate an AND x = 'y' to the query, or should I write the extra code to check if a clause has been added and if not, add the AND ? Confusing question, I know. Let me know if I need to be more clear. Rob

  • Getting anchor text from a webpage using xpath within YQL

    - by Matt
    SELECT content FROM html WHERE url="http://en.wikipedia.org/wiki/List_of_United_States_National_Parks_by_state" AND xpath="//a/text()" does not work, whereas SELECT * FROM html WHERE url="http://en.wikipedia.org/wiki/List_of_United_States_National_Parks_by_state" AND xpath="//a/text()" does. SELECT content FROM html WHERE url="http://en.wikipedia.org/wiki/List_of_United_States_National_Parks_by_state" AND xpath="//a" also works, it seems YQL has a bug, or am I missing something?

  • Popup browser incompability

    - by Cornelis
    I have a popup with drop down menus on it. I've scaled it down and simplified it for test purposes, but it still doesn't work the way I want/it should. <!DOCTYPE html> <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script> <script type="text/javascript"> jQuery(document).ready(function(){ jQuery('.trigger').click(function(){ var picker = jQuery('.popup'); jQuery('<div></div>').css({ height: screen.height, width: screen.width, position: 'absolute', 'z-index': -1, top: picker.offset().top*-1, left: picker.offset().left*-1, border: '1px solid red' }).click(function(){ picker.trigger('focusout'); jQuery(this).hide(); }).prependTo(picker); picker.css('visibility', 'visible'); }); jQuery('.popup').live("focusout", function() { jQuery('.popup').fadeTo(500, 0.0, function() { jQuery('.popup').css('visibility', 'hidden'); jQuery('.popup').css('opacity', '1.0'); }); }); }); </script> </head> <body> <p> <input type=text class=trigger /> <div id=popup-div class=popup style="visibility: hidden; border: 1px solid red"> <select> <option>option1</option> </select> <p>Popup text</p> </div> </p> </body> When you click on the input field, a 'popup' appears, if you click outside the red border it fades away. If you click on the select option it shouldn't dissappear! However on this point, Chrome doesn't work the same as IE/FF/Opera/Safari, and makes the div dissappear. (Using Chrome 4.0.295.0) Does anybody knows a work-around for Chrome? Calling event.stopPropagation() on select elements did not work so far

  • What benefits are there to storing Javascript in external files vs in the <head>?

    - by RenderIn
    I have an Ajax-enabled CRUD application. If I display a record from my database it shows that record's values for each column, including its primary key. For the Ajax actions tied to buttons on the page I am able to set up their calls by printing the ID directly into their onclick functions when rendering the HTML server-side. For example, to save changes to the record I may have a button as follows, with '123' being the primary key of the record. <button type="button" onclick="saveRecord('123')">Save</button> Sometimes I have pages with Javascript generating HTML and Javascript. In some of these cases the primary key is not naturally available at that place in the code. In these cases I took a shortcut and generate buttons like so, taking the primary key from a place it happens to be displayed on screen for visual consumption: ... <td>Primary Key: </td> <td><span id="PRIM_KEY">123</span></td> ... <button type="button" onclick="saveRecord(jQuery('#PRIM_KEY').text())">DoSomething</button> This definitely works, but it seems wrong to drive database queries based on the value of text whose purpose was user consumption rather than method consumption. I could solve this by adding a series of additional parameters to various methods to usher the primary key along until it is eventually needed, but that also seems clunky. The most natural way for me to solve this problem would be to simply situate all the Javascript which currently lives in external files, in the <head> of the page. In that way I could generate custom Javascript methods without having to pass around as many parameters. Other than readability, I'm struggling to see what benefit there is to storing Javascript externally. It seems like it makes the already weak marriage between HTML/DOM and Javascript all the more distant. I've seen some people suggest that I leave the Javascript external, but do set various "custom" variables on the page itself, for example, in PHP: <script type="text/javascript"> var primaryKey = <?php print $primaryKey; ?>; </script> <script type="text/javascript" src="my-external-js-file-depending-on-primaryKey-being-set.js"></script> How is this any better than just putting all the Javascript on the page in the first place? There HTML and Javascript are still strongly dependent on each other.

  • Adjust OSX System Audio Volume in Python

    - by Benson
    I would like to adjust the system audio volume in OSX from a python script. This question about implementing keyboard shortcuts tells me how to do it in applescript, but I'd really like to do it from my python script without using os.system, popen, etc. Ideally I'd like to ramp up the volume slowly with some python code like this: set_volume(0) for i in range(50): set_volume(i*2) time.sleep(1)

  • REST/JSON: Should I include a newline after the JSON string?

    - by Mark Harrison
    If I'm returning ["foo"] from a RESTful web query, Which of these is more proper? Will pedantic REST parsing die on the newline? ["foo"]\n (with newline, Content-Length=8) ["foo"] (no newline, Content-Length=7) For easy regression testing I like the form with the newline, but I want to make sure I won't be breaking any application frameworks that might have a more strict view of the REST format.

  • Future proof Tweeting with PHP

    - by YsoL8
    Hello I'm looking to implement a system for tweeting directly from my site backend, which is written in PHP 5. I have a script from the internet that I can adapt, but I'm concerned that when Twitter switches to Oauth only, I'll be out in the cold. Basically, I'm hoping someone can point me toward a script/tutorial that will let me do the following: access twitter via the Oauth system Post Tweets and receive error codes Let me define an application/site name (I'm a bit fuzzy on whether Twitter allows this) Ideally I need all 3 points explained in detail. Thanks

  • Actionscript base class in Flex AIR app

    - by Alan
    I'm trying to build a Flex AIR app using Flex Builder 3, which I'm just getting started with. In Flash CS4, there's a text field in the authoring environment where you can specify a class that will become the "base" class - your class inherits from Sprite and then "becomes" the Stage at runtime. Is there a a way to do the same thing with Flex/AIR? Failing that, can anyone explain how to create and use an external class? Originally I had this in TestApp.mxml: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script source="TestApp.as"/> </mx:WindowedApplication> And this in TestApp.as: package { public class TestApp { public function TestApp() { trace('Hello World'); } } } That gives the error "packages cannot be nested", so I tried taking out the package statement: public class TestApp { public function TestApp() { trace('Hello World'); } } That gives an error "classes cannot be nested", so I finally gave up and tried to take out the class altogether, figuring I'd try to start with a bunch of functions instead: function init() { trace('Hello World'); } But that gives the error "A file found in a source-path must have an externally visible definition. If a definition in the file is meant to be externally visible, please put the definition in a package". I can't win! When I put my class in a package, it says I can't do that because it would be nested. When I don't, it says it needs to be in a package so it can be seen. Does anyone know how to fix this? If I can't do the custom-class-as-base-class thing, is there a way I could just have it like: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script source="TestApp.as"/> <mx:Script> var app = new TestApp(); </mx:Script> </mx:WindowedApplication> At the moment I can't import the class definition at all, so even that won't work. Thanks in advance!

  • How can i convert this to a factory/abstract factory?

    - by Amitd
    I'm using MigraDoc to create a pdf document. I have business entities similar to the those used in MigraDoc. public class Page{ public List<PageContent> Content { get; set; } } public abstract class PageContent { public int Width { get; set; } public int Height { get; set; } public Margin Margin { get; set; } } public class Paragraph : PageContent{ public string Text { get; set; } } public class Table : PageContent{ public int Rows { get; set; } public int Columns { get; set; } //.... more } In my business logic, there are rendering classes for each type public interface IPdfRenderer<T> { T Render(MigraDoc.DocumentObjectModel.Section s); } class ParagraphRenderer : IPdfRenderer<MigraDoc.DocumentObjectModel.Paragraph> { BusinessEntities.PDF.Paragraph paragraph; public ParagraphRenderer(BusinessEntities.PDF.Paragraph p) { paragraph = p; } public MigraDoc.DocumentObjectModel.Paragraph Render(MigraDoc.DocumentObjectModel.Section s) { var paragraph = s.AddParagraph(); // add text from paragraph etc return paragraph; } } public class TableRenderer : IPdfRenderer<MigraDoc.DocumentObjectModel.Tables.Table> { BusinessEntities.PDF.Table table; public TableRenderer(BusinessEntities.PDF.Table t) { table =t; } public MigraDoc.DocumentObjectModel.Tables.Table Render(Section obj) { var table = obj.AddTable(); //fill table based on table } } I want to create a PDF page as : var document = new Document(); var section = document.AddSection();// section is a page in pdf var page = GetPage(1); // get a page from business classes foreach (var content in page.Content) { //var renderer = createRenderer(content); // // get Renderer based on Business type ?? // renderer.Render(section) } For createRenderer() i can use switch case/dictionary and return type. How can i get/create the renderer generically based on type ? How can I use factory or abstract factory here? Or which design pattern better suits this problem?
