• Jquery ajax and php die()

  - by BizMark

  Hi, I have an IE problem. I am using the jquery ajax method to call a php script. The php script just calls die(). In firefox, the error message is displayed, but in IE the success message is displayed without any data. I would prefer the error function to be called. Is there any way to fix this? I'm guessing my javascript code needs change somehow. Thanks! <?php die() ?> $.ajax({ url: "phps/php.php?id="+the_id, dataType: "json", error: function(){ alert('error'); }, success: function(data){ alert("SUCCESS"); } });

• Backbone.js: How to utilize router.navigate to manipulate browser history?

  - by Xavier_Ex

  I am writing something like a registration process containing several steps, and I want to make it a single-page like system so after some studying Backbone.js is my choice. Every time the user completes the current step they will click on a NEXT button I create and I use the router.navigate method to update the url, as well as loading the content of the next page and doing some fancy transition with javascript. Result is, URL is updated which the page is not refreshed, giving a smooth user experience. However, when the user clicks on the back button of the browser, the URL gets updated to that of a previous step, but the content stays the same. My question is through what way I can capture such an event and currently load the content of the previous step and present that to the user? Or even better, can I rely on browser cache to load that previously loaded page? EDIT: in particular, I'm trying something like mentioned in this article.

• Retain Site Background and Switch Pages?

  - by yar

  I was about to redo a Rails site today using AJAX so that the background could remain in place. Then I thought, "that would be exactly like using frames," and then I thought about SEO consequences and I dropped the idea entirely and took a look around the Web. It turns out that few sites -- except for Google itself, which has the link bar at the top -- are doing this. It doesn't look impossible to do, but it's not exactly easy. Aside from Ajaxing, you have to think about updating the query-string and having SEO-friendly links (that actually don't work, but rather make background requests via Javascript). Will any of the new technologies -- HTML5, perhaps -- solve this problem and allow us to have a Web with background colors (and other static elements) that do not disappear momentarily between page refreshes? On the other hand, why are few devs doing this with current technologies? Is it just not a big deal, too complicated to implement, or....?

• Difference between SRC and HREF

  - by Vijey

  The SRC and HREF attributes are used to include some external entities like an image, a CSS file, a html file, any other web page or a javascript file. Is there a clear differentiation between SRC and HREF? where/when to use SRC or HREF? I think they can't be used interchangeably. I'm giving below few examples where these attributes are used: To refer a CSS file: href="cssfile.css" inside the link tag To refer a js file: src="myscript.js" inside the script tag To refer an image file: src="mypic.jpg" inside an image tag To refer another webpage: href="http://www.webpage.com" inside an anchor tag

• Using jquery to disable function untill all selects are changed

  - by richbyte

  I am using a javascript function (F) (jquery )which uses 3 select values selected by the user to calculates a value - R(result) R is a number ranging from (1 through 9), (11) and (22); I need 2 extra steps one before the calculation and one after. a. Before calculation takes place: Make sure all three select values are changed before function(F) takes place. If not prompt the user with a notice ( create dom element/ I am using jquery) b. After the value R is calculated show an element corresponding to the result e.g. if R is 1 show an element ( a predetermined "link" element corresponding to each result value) thanks a lot.

• Metro style apps with Html and C#

  - by labroo

  According to this slide http://geekswithblogs.net/images/geekswithblogs_net/technetbytes/windows-8-platform-tools.jpg Does it mean I have to use XAML view with C# if I want to develop a metro styled application? Can I use a HTML/JS/CSS - C# combination with event handlers and all? Something like ASP.NET Webforms/MVC . I know it is not the same client server architecture, but since metro styled apps support HTML/JS, I was wondering. I can use Win-JS. But can I rather write C# than Javascript, and use HTML rather than XAML?(I dont know XAML and I like C#) All the C# samples I found online use XAML.

• ASP.NET MVC vs. Jquery/AJAX (Where to draw the dividing line?)

  - by punkouter

  I am learning MVC and I understand the basics now. It is very good for CRUD pages and has built in HTTP methods to post/get edits/updates. That is nice. This is all very testable by just creating a new controller and testing it. But I was thinking about other web page scenerios when using MVC. What about a page that has 2 listboxes that you add/remove users with. (A button will move the user from one listbox to another) This would be done using Jquery/Javascript... But then what happens to testing? How do you test adding/removing users from a listbox like that example? It seems to me the more jquery you use the less testable the page becomes right? When you get beyond basic forms being filled out then you need to use something more than the standard MVC pages. What is the correct philosophy on this on when am I not understanding ?

• Can the Browser 'Forward' Button be Set from HTML?

  - by John C

  Example: At the bottom of the StackOver Questions page are a bunch of page numbers (1,2,3...), enclosed in a set of prev and next buttons. Clicking next repeatedly will bring me to, say page 5, at which point I will have: The page's prev button will be set to 'http://stackoverflow.com/questions?page=4' The Back button on my Browser will have the same value. The page's next button will be set to 'http://stackoverflow.com/questions?page=6' The Forward button on my Browser - won't be set to anything. Obviously, if I hit the Back button on the Browser, then Forward will have a value, pointing to the URL for page 5 - but not otherwise. Is there any way, from HTML (plus Javascript), to set the value of the Browser's Forward button? Or is this one of those things that HTML is simply forbidden to do?

• How can I keep up to date on the latest web development standards?

  - by Structure

  First off, I know that this question begs the other question - should the latest web development standards be followed and further will they remain relevant? That aside, I am focused on GUI development, usability, etc. Front-end web development that utilizes XHTML, CSS, JavaScript, etc. I know there are many gurus and thought leaders out there but with my projects I simply do not always have time to follow them all and keep up with the latest development standards. However, this is obviously very important. So how can I keep myself up to date on the latest web development standards while maintaining productivity? Are there any specific groups or organizations to monitor for this? Best practices that one might follow?

• Possibly simple PHP/MYSQL issue with retrieving and showing data

  - by envoys

  I have been racking my brains over this for a while now. Here is the data i have in the sql data base as an example: ID | TYPE | DATA 1 | TXT | TEST 2 | PHP | php 3 | JS | JAVASCRIPT That is just an example, there are multiple listing for TXT, PHP and JS throughout the table. What I want to do is retrive all the data and display it all into separate drop down/select boxes. Meaning, select box one would list all data with type TXT, select box two would list all data with type PHP and select box 3 would list all data with type JS. The only way I have came about doing this is doing individual sql queries for each different type. I know there is a way to do it all in 1 query and then display it the way I want to but I just can't seem to figure out how and I know its going to drive me nuts when someone helps and I see just how they did it. Thanks for the input.

• JQuery (1.4.2)/Firefox (3.6.3) - .before and .after not working on div

  - by user355561

  I am trying to have a title bar appear when the user clicks on a box. It works perfectly in I.E. 8.0 but not at all in firefox 3.6.3. HTML [code] @import url('style.css'); blah blah blah save changes [/code] Javascript [code] $(document).ready(function(){ $("#edit2").live('click',function(){ if($("#menu").length == 0){ $("#edit2").before(''); } if($("#menu2").length == 0){ $("#edit2").after(''); } this.contentEditable = true; this.focus(); }); $("#edit2").live('blur',function(){ $("#menu").remove(); //$("#menu2").remove(); this.contentEditable = false; }); }); [/code] Could anyone suggest why it's not working? I have managed to use similar code to add/remove new table rows in both browser but I just can't see why this doesn't also work.

• Can I preload multiple video resources to load in the same HTML5 <video> element?

  - by Sergio1132

  I'm working out details on a web application which involves the sequential loading of a long series of (very short) video clips, one after the other, with occasional input from the user establishing new directions for which video clips to load. I would like to be able to have the browser preload the video clips five at a time. However, the way that we currently have the site working is by means of a single video element which is having its src attribute continually updated through JavaScript. So, my question is, is there a straightforward way I can get the browser to preload multiple video clips even though I am ultimately loading them all (one at a time) into the same video element? This is my first question here, so let me know if I could have phrased that better...

• How do I overflow text to the left in a table?

  - by remack

  I have a table with fixed layout. On overflow, the contents of cells should clip from the left instead of the right. That is, if the width of the TD is less than the width of the text, the cell below should display "67890" instead of "12345". This needs to work in IE7+ at minimum. Is there a way to do this in css without any JavaScript? <table style="table-layout:fixed"> <tr> <TD> 12334567890 </TD> </tr> </table>

• How can I capitalize the first letter of an input ?

  - by Safirio

  I'm currently trying to capitalize the very first letter from an input. Here's what I tryed : fieldset input { text-transform:capitalize; } But it doesn't work the way I want, as every word is capitalized. I also tryed this : fieldset input:first-letter { text-transform:uppercase; } But it seems <input /> doesn't work at all with first-letter... Anyway, do you have any idea of how to achieve this without javascript (or as little as possible) ?

• hook to save action in eclipse plugin

  - by 4485670

  I want to create a Google Closure Compiler plugin for eclipse. I already have a popup menu entry to compile a Javascript file to its minified version. But it would be more than helpful if every time you save a *.js that minified version would be generated automatically. I read/heard about natures and builders, extension points and IResourceChangeListener. But I did not manage to figure out what I should use and especially how to get it to work. Is there a working example of a plugin that does "the same kind of thing" so I can work from that or a tutorial to write such? With the answer below I searched for projects that use the IResourceChangeListener and came up with this code: manifest: http://codepaste.net/3yahwe plugin.xml: http://codepaste.net/qek3rw activator: http://codepaste.net/s7xowm DummyStartup: http://codepaste.net/rkub82 MinifiedJavascriptUpdater: http://codepaste.net/koweuh There in the MinifiedJavascriptUpdater.java which holds the code for the IResourceChangeListener the "resourceChanged" function is never reached.

• Need to add specific characters to regular expression

I know the pro's and cons of using javascript to validate email addresses - i have to do it this way. thanks.

• Have anyone ever create/manipulate a table application from the ground up/scratch?

  - by Darwin

  Have anyone ever create/manipulate a table application from the ground up/scratch? I want to create a table using flash AS 3. I like to have the features like to the MS Studio Web Developer option. The options are create a table, merge cells, split cell, resize columns, delete cell, delete row, delete column etc... I think this is going to be very complicated thing to do. I think the only way to do it is to build it from the ground up because I don’t think Flash has the library/component for it. I was able to create rows and columns by creating the # of rectangles listed it from the left to the right and move the next coordinate for the next row. Now the most challenging this is to manipulate it. This is the must have feature on my website and we don’t want use Javascript to create table on the server side to create the table.

• Perform tasks with delay, without delaying web response (ASP.NET)

  - by Tomas Lycken

  I'm working on a feature that needs to send two text messages with a 30 second delay, and it is crucial that both text messages are sent. Currently, this feature is built with ajax requests, that are sent with a 30 second javascript delay, but since this requires the user to have his browser open and left on the same page for at least 30 seconds, it is not a method I like. Instead, I have tried to solve this with threading. This is what I've done: Public Shared Sub Larma() Dim thread As New System.Threading.Thread(AddressOf Larma_Thread) thread.Start() End Sub Private Shared Sub Larma_Thread() StartaLarm() Thread.Sleep(1000 * 30) StoppaLarm() End Sub A web handler calls Larma(), and StartaLarm() and StoppaLarm() are the methods that send the first and second text messages respectively. However, I only get the first text message delivered - the second is never sent. Am I doing something wrong here? I have no deep understanding of how threading works in ASP.NET, so please let me know how to accomplish this.
