Get the jQuery Version
Many JavaScript frameworks provide a version property on their main object, providing a quick bit of important information about the framework. The main jQuery object doesn't provide this property, however, so developers need to do a bit more work to get that version information. Here's how to get the jQuery version number for a given jQuery script!
The jQuery JavaScript
The jQuery version lives within jQuery.fn:
var v = jQuery.fn.jquery;
/*
You may also use:
var v = jQuery().jquery; // "1.4.2"
*/
The jquery property of the jQuery.fn object provides the version number as a string. Not as easy as .version access, but provides the jQuery version nonetheless!
