How to determine and print jQuery version?
JavascriptJqueryJavascript Problem Overview
Is there a jQuery function that returns the version of jQuery that is currently loaded?
Javascript Solutions
Solution 1 - Javascript
You can use this:
$.fn.jquery
//or if you're using .noConflict():
jQuery.fn.jquery
It's updated automatically when jQuery is built, defined here: http://github.com/jquery/jquery/blob/master/src/core.js#L174
Make sure to use $.fn.property for properties that don't depend on an object, no reason to create an unneeded jquery object with $().property unless you intend to use it :)
Solution 2 - Javascript
alert( $.fn.jquery )
Solution 3 - Javascript
I'm not sure how many versions of jQuery this exists in, but a jQuery object has a jquery property that stores the version.
alert( $().jquery );
Will alert 1.4.2 if you're using that version.
Solution 4 - Javascript
$().jquery;
This will return a string containing the jQuery version
Solution 5 - Javascript
$().jquery; // yields the string "1.4.2", for example

Solution 6 - Javascript
try
alert($().jquery)
Solution 7 - Javascript
Alert is good, but if you want to actually print the jquery version...
<script>
document.write($.fn.jquery);
</script>
