• Easiest way to create twitter-like status update widget

  - by culov

  I want a widget that allows users to add a request if that request hasnt already been added, or vote for a request if it has already been added. when a user adds a request, i want it to immediately appear as the first element of the list, like what would happen to your timeline if you made new tweet. ive tried to look for a jquery plugin that offers this functionality, but i was unsuccessful (maybe i couldnt think of the right terms to search for??). i dont have enough faith in my js skills to write this from scratch, so id rather find a template to start with. Thanks.

• Searching for a semantic syntax highlighter in Javascript

  - by Boldewyn

  OK, I know, there are literally dozens of already available syntax highlighters out there. But I want one specifically, that implements line numbers through <ol/> lists. And that reduces the number of possible candidates to one, Lighter.js. Unfortunately, that is MooTools based, and since I decided some time ago to use jQuery, I don't want to embed yet another library just for syntax highlighting. The SyntaxHighlighter does something similar, but uses tables for the line numbering, and I don't want to hack it, if there is an already available tool, too.

• Free Online tools for testing mysql queries - having features like PhPMyAdmin

  - by Sandeepan Nath

  Can anybody tell me any "free online hosted database servers" (don't know if that is the correct term) where we can do query testing and all those things that we can do on tools like PhpMyAdmin? does something like that exist? Like we have http://jsfiddle.net/ for testing js codes. I checked http://sqlzoo.net/ but this is very much limited and there are some predefined tables in some given examples on which we can alter things. That's all. It does not allow me to do a lots of other things like creating tables etc. A nice resource - PhpMyAdmin's demo site . Use the latest stable version here. You have full control over the MySQL server, however you should not change root, debian-sys-maint or pma user password or limit their permissions. If you do so, demo can not be accessed until privileges are restored, so you just break things for you and other users.

• Problem With HTML5 Application Cache Whitelist - Won't Ignore Items

  - by Ryan Donnelly

  I'm trying to use HTML5 Application Cache to speed some things up on an iPhone webapp. It works great for storing images, css and JS, but the problem is that it also tries to store the HTML. I haven't been able to get it to ignore the html and stop storing it in the cache. From what I've read, I have to "whitelist" the files and directories that I want to load no matter what. I've tried listing the files I want cached explicitly, and I've tried adding a series of things under the "NETWORK:" heading. I've tried * / /* http://mysite.com http://mysite.com/ http://mysite.com/* None of them seem to work. Is there any way to ignore HTML files by MIME-Type or anything? Any advice would be appreciated. Ryan P.S. Of course, my site is not mysite.com..I just used that for simplicity.

• ASP.NET MVC 2 relative paths for scripts and styles

  - by Tomaszewski

  Hi, having this really silly problem in ASP.NET MVC 2 with .NET 4. I need to test other pages using localhost, but sometimes I need to show the page to some else on another computer and so need to path out to my machine. In doing so, I need to use relative paths for my and tags. When I test through VS, I use relative path: <script src="../../Scripts/somejavascript.js"></script> <link href="../../Styles/somestyle.css" /> However, when I publish to local IIS, I'm having all sorts of problems beacuse the Scripts and Styles folder are at the same directory level, but it seems like I have to path out differently. For example, in the scenario above the styles will be picked up but the JavaScript won't be. Any ideas on how best to path out, relatively using MVC 2?

• Sending most correct mimetype

  - by Roland Franssen

  Hi all, I have a list of extension to mimetype in a INI file. However some extensions have multiple mimetypes, for example; midi[] = "application/x-midi" midi[] = "audio/midi" midi[] = "audio/x-mid" midi[] = "audio/x-midi" midi[] = "music/crescendo" midi[] = "x-music/x-midi" 6 (possible) mimetypes for 1 extension. Whats common practice to determine the correct mimetype? (e.g. i need to set a HTTP content-type header). I know its not ideal; determining mimetypes based on extension.. but i need consistent (cross-server) results (e.g. fileinfo extension in PHP is making terrible guesses*). * Some fileinfo results for example; js - text/plain css - text/c-h

• Javascript - how to change elements content inside a page when using iframes, using dom, not jquery

  - by Erez

  Hello all, I have this iframe and as u can see it call a js function with the onload trigger. <iframe name="top" id="top" width="99%" height="20%" src="top.htm" frameborder="0" scrolling="no" onload="log_in()"></iframe> What i need to do is to effect the element inside "top.htm" (change innerHTML and stuff like that) from that function. But the problem is that the funnction does not recognize the elements of the "top.htm" page, only the ones in index.htm (the page with the iframes). p.s. i have to use DOM and i have to use iframes. Any one knows how to do that? 10x :-)

• Preserve onchange for a dropdown list when setting the value with Javascript.

  - by Zac Altman

  I have a dropdown list with a piece of code that is run when the value is changed: <select name="SList" onchange="javascript:setTimeout('__doPostBack(\'SList\',\'\')', 0)" id="SList"> Everything works fine when manually done. As an option is selected, the onchange code is called. The problem begins when I try to change the selected value using a piece of Javscript. I want to be able to automatically change the selected option using JS, whilst still having the onchange code called, exactly as if done manually. I try calling this: form.SList.value = "33"; The right option is selected, but the onchange code does not get called. So then I try doing this: form.SList.value = "33"; javascript:setTimeout('__doPostBack(\'SList\',\'\')', 0); The right value is not selected and nothing happens. FYI, the code is done in ASP.NET and Javascript. What can I run to change the selected option whilst still calling the onchange code?

• How can I detect if the browser has encountered a JavaScript error ... in JavaScript?

  - by RichH

  For automated testing reasons I want to detect if the browser has encountered JavaScript errors for a page. The type of things that would cause the red numbers in the bottom right in Firebug or yellow warning icon in the Internet Explorer status bar. These JS errors could come from any one of a large numbers of scripts. How in JavaScript can I detect these browser errors? Cross browser solutions prefered, but hey, I'll take anything! As a bonus it would also be great to know the script that caused the error.

• Doing ajax with Jquery.

  - by user272899

  I have been loading content with ajax and all works fine. Here is my code $(document).ready(function() { //Load a-z.php //Timestamp resolves IE caching issue var tsTimeStamp= new Date().getTime(); $.post('../../includes/categories/a-z.php', {action: "post", time: tsTimeStamp}, function(data){ $('#moviescontainer').html(data).slideDown('slow'); }); return true; }); My data inside a-z.php requires Javascript for it's content and when I load a-z.php onto my page the javascript doesn't work. I am quessing that I need to link the relevant files to a-z.php and then load it via ajax. Doesn't this kind of defeat the object of ajax?? That means that I will be loading the js files on the main page and then loading them again when I ajax a-z.php I hope I made some sense.

• DurandalJS vs AngularJS?

  - by Zach

  I'm looking for a JS framework to build an SPA and found DurandalJS and AngularJS. Can anyone compare these two frameworks? I did find many articles that compares AngularJS and KnockoutJS, and they say AngularJS is more than data binding, so I think DurandalJS may be the one to compare. I did a little research on AngularJS, it is good but one thing is bad: the $ prefix does not work when minified, although there is an ugly workaround. And someone said Twitter Bootstrap does not work well with it (I didn't check). For DurandalJS, I still cannot find the samples (http://durandaljs.com/documentation/Understanding-the-Samples/), so it's hard to say. PS: are they working well with TypeScript? Best regards, Zach

• Do you know any code sharing sites?

  - by jasondavis

  I am always looking to organize and make my resource bookmarks better and easiar to access when I need them. 1 thing I really like is code sharing sites, they let you enter in code and then give you a special link to give a friend or a user on this site even to show then code, This is a very useful tool I believe. So below is my list of code sharing sites, there is 4 on the list and they all have unique features. Some have syntax highlighting for multiple languages, some allow you to save your code as private and only share with the people you give the link to, and some even run the run and output any possible errors. Do you know of any sites like this? if you know of any sites like this for programming code please post it here. http://pastie.org/ http://codepad.org/ http://pastebin.me/ http://jsbin.com/ allows you to auto-insert a javascript library like jquery and test live js code

• Flash not interacting with Javascripts in browser inside my app

  - by Shivaprasad

  Hi , I have an application which embeds a xulrunner based browser. I have to load some flash content in it which talks to some javascripts to update the browser title. The flash content works fine when launched from Firefox but not inside my app. I tried a sample html file which has some javascripts and they work fine. It even works when I have the flash content on a server. It is only when I try to run js through flash present on my local machine that I see this problem. I guess it must have something to do with some security settings in xulrunner. Could somebody help me figure out what the problem might be? Thanks jbsp72

• Simplest possible table entry editing / addition / deletion web toolkit (for use with php)

  - by Dave

  Hi, i'm building a website in php and i have tables presented that i need to allow the user to: 1. add new entry (only one at a time, which should appear as a new modal overlay) 2. delete multiple selected entries from 3. edit an existing entry (only one at one time, in a view similar to 1.) 4. re-arrange entries up and down. One by one is fine. Multiple / Grouping rearrangements are not not needed what jquery / js / anything toolkit would be the SIMPLEST to work with? (of course, i should be able to work with it in php). I did try hacking away at: http://www.ericmmartin.com/projects/simplemodal/ but had a terrible time trying to get it to work on editing some existing data (had problem passing data to it).

• Passing Querystring style parameters into Javascript file

  - by Mike Mengell

  Hi, Not sure if this is possible or even if I should do it, but I think it's quite interesting. I have a javascript file which I'm referencing in a flat HTML page. I'd like to pass in a parameter or two via the path to the script. Like this; <script src="/scripts/myJavascriptFile.js?config1=true" type="text/javascript"></script> Not really sure if it can work but it would make my solution a little easier for others to take my script and implement (arguable). Cheers, Mike

• JavaScript: window.opener.location.href question

  - by vastbeyond

  I need to make a little JS app to scroll automatically through a list of URLs. I've chosen to have the functionality in a pop-up, for various reasons. The syntax to change the opening window's URL is: window.opener.location.href = "http://www.example.com"; This works fine with one URL, but if two statements are called, only one is executed. I experimented with an alert statement between two of the above statements, and the alert event made the second statement function properly: window.opener.location.href = "http://www.example1.com"; alert("hello world"); window.opener.location.href = "http://www.example2.com"; Question is: does anyone know how to get the first and second window.opener statements to work, without the intervening alert();? Also, how can I add a pause between the two statements, so that the second executes a couple of seconds after the first? Thanks so much!
