So for example: <ul id="home"> <li id="navtab"> <a id="home-link" onclick="doHome();">HOME</a> </li> </ul> And the anchors ...

Hi all! jQuery.ready() allows us to wait for the construction of the webpage. Recently it has been added support to wait until CSS files are loaded. I would like to know if that feature can be used for downloaded content, because I fetch content via $.ajax() that holds CSS references and I would like to retrieve the content of the CSS...

Hi, I'm putting together a C# winforms application, and it would be good to be able to have the ability for someone to click on a webpage link that automatically maximizes my c# application and passes some data to it. Pretty much like I see some webpages have a song link that automatically opens iTunes, and then in iTunes it searches f...
A nasty gotcha in javascript is forgetting to call new on a function meant to be instantiated, leading to this being bound to a different object (usually the global) instead of a fresh one. One workaround I read about is to check for it explicitly in the function-constructor using the following idiom: function SomeConstructor(x, y, ...)...
I have a web page where I want to display hotel reviews from the yelp.com API for a number of hotels.

Meebo's new 'bar' service puts a floating bar with links and chat functions at the bottom of any given webpage with just a dash of Javascript and HTML. I'd like to build something like it, but I'm flummoxed as to how they got around the same origin issues. It looks like they're injecting an iframe and some script tags, but how they acco...

I'm using JavaScript with the jQuery library to manipulate image thumbnails contained in a unordered list. When the image is loaded it does one thing, when an error occurs it does something else. I'm using jQuery load() and error() methods as events. After these events I check the image DOM element for the .complete to make sure the imag...
I am trying to include the js and css in my code behind in my master pages and user controls in Page_Load event. But apparently, js breaks since Page_Load of user controls loads BEFORE Page_Load of a master page. I include my jquery libs used across the site in my master pages, but scripts used in user control are included in user cont...
So I don't actually mean browser caching of an Ajax request using the GET method, but storing large queries (any number, likely double-digits, of 40 - 300kb queries) in the the browser's memory. What are the unseen benefits, risks associated with this? var response = JSON.parse(xhr.responseText); Cache.push(response); // Store parsed J...
What are the exact circumstances for which a return statement in Javascript can return a value other than this when a constructor is invoked using the new keyword? Example: function Foo () { return something; } var foo = new Foo (); If I'm not mistaken, if something is a non-function primitive, this will be returned. Otherwise som...
