(Actually, using the very latest versions of everything isn't always wanted, especially in large companies where browsers are older.)

 emanuele tried a variant:

Code: [Select]

loadJquery("2.0.3", function ($) {
	// Here it goes my code that works only with version 2.0.3
});

function loadJquery(ver, callback)
{
	var url = 'http://ajax.googleapis.com/ajax/libs/jquery/' + ver + '/jquery.min.js',
		script = document.createElement("script");
	script.type = "text/javascript";
	script.src = url;

	if (typeof(jQuery) == "undefined")
	{
		appendjQuery(script, callback);
	}
	else
	{
		compareJQueryVersion(jQuery.fn.jquery, ver, function (result) {
			switch(result) {
				case false:
				case 1:
					callback(jQuery);
					break;
				case 2:
					appendjQuery(script, callback);
			}
		});
	}
};

function appendjQuery(script, callback)
{
	var head = document.getElementsByTagName("head")[0],
		done = false;

	script.onload = script.onreadystatechange = function() {
		if (!done && (!this.readyState || this.readyState == "loaded" || this.readyState == "complete"))
		{
			done = true;
			callback(jQuery.noConflict());
			script.onload = script.onreadystatechange = null;
			head.removeChild(script);
		};
	};
	head.appendChild(script);
}

function compareJQueryVersion(v1, v2, callback)
{
	var v1parts = v1.split('.');
	var v2parts = v2.split('.');

	for (var i = 0; i < v1parts.length; ++i)
	{
		if (v2parts.length == i)
		{
			//v1 + " is larger"
			callback(1);
			return;
		}

		if (v1parts[i] == v2parts[i])
		{
			continue;
		}
		else if (v1parts[i] > v2parts[i])
		{
			//v1 + " is larger";
			callback(1);
			return;
		}
		else
		{
			//v2 + " is larger";
			callback(2);
			return;
		}
	}

	if (v1parts.length != v2parts.length)
	{
		//v2 + " is larger";
		callback(2);
		return;
	}
	callback(false);

	return;
}
