A Plugin to help determine the version of jQuery.

Code:

 function jQueryVersion()
{
    var ver = (new jQuery()).jquery;
    // if there are two .'s it is a bug fix release
    if(ver.match(/\./g).length == 2)
    {
        return {
            "version" : ver,
            "major" : ver.substr(0, ver.indexOf(".")),
            "minor" : ver.substr(ver.indexOf(".") + 1, ver.lastIndexOf(".") - ver.indexOf(".") - 1),
            "revision" : ver.substr(ver.lastIndexOf(".") + 1)
        }
    }
    // otherwise it is an initial release
    else
    {
        return {
            "version" : ver,
            "major" : ver.substr(0, ver.indexOf(".")),
            "minor" : ver.substr(ver.indexOf(".") + 1),
            "revision" : 0
        }
    }
}

Usage example:

 jQuery.fn.myplugin = function()
{
    var version = jQueryVersion();
    if(parseInt(version.minor) < 1)
    {
        alert("jQuery version 1.1 or higher is required for myplugin");
        return this;
    }
}
