How to multiple version of jQuery?
Yes. You can use multiple versions of jQuery on the same page. To avoid any kind of conflict, use the jQuery.noConflict() method.
<script>var $jq = jQuery.noConflict(true);</script>
<script>
$(document).ready(function(){
$("button").click(function(){
alert($().jquery);
alert($jq().jquery);
});
});
</script>
While executing code, $.noConflict() method to give control of the $ variable back to whichever library first implemented it.
Browser View
<html>
<head>
<title>Multiple Version</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script>var $jq = jQuery.noConflict(true);</script>
<script>
$(document).ready(function(){
$("button").click(function(){
alert($().jquery); // This prints v3.3.1
alert($jq().jquery); // This prints v1.4.2
});
});
</script>
</head>
<body>
<button>Check Multiple version</button>
</body>
</html>
jQuery.noConflict() method
jQuery.noConflict() method allows you to use multiple frameworks , while using jQuery. The noConflict() method releases the hold on the $ shortcut identifier, so that other scripts can use it. In jQuery's case, $ is just an alias for jQuery, so all functionality is available without using $. In case of multiple versions of jQuery are loaded (which is not recommended), calling $.noConflict(true) from the second version will return the globally scoped jQuery variables to those of the first version.
