The Pushlets team has added Ajax to their HTTP-based publish/subscribe framework. You can check out an example here. In the code they have functions for the various events: function leave() { doRequest(‘/pushlet/pushlet.srv?p_event=leave&p_id=’ + sessionID ); } and then the typical XHR to access the pushlet server side: function doRequest(url) { // Create XMLHttpRequest object and Read the rest…

In the “cool JavaScript snippets” department, we delve into the Prototype library for a nice function which tries to fire and forget through a set of operations.

“JavaScript doesn’t seem very OO”. I hear that a lot. How far from the truth it is though. A lot of us are just trained to think that OO == CLASS BASED OO, which has won out in a lot of popular OO languages of late. JavaScript is fully OO, and arguably more so than Read the rest…

A lot of people are not aware of Douglas Crawford’s JavaScript Minifier which does what it says on the box: JSMin is a filter which removes comments and unnecessary whitespace from JavaScript files.
