What is jQuery.noConflict?

Answer 1

The noConflict() method releases the hold on the $ shortcut identifier, so that other scripts can use it.
You can of course still use jQuery, simply by writing the full name instead of the shortcut:

$.noConflict();
jQuery(document).ready(function(){
    jQuery("button").click(function(){
        jQuery("p").text("jQuery is still working!");
    });
});

You can also create your own shortcut very easily. The noConflict() method returns a reference to jQuery, that you can save in a variable, for later use. Here is an example:

var jq = $.noConflict();
jq(document).ready(function(){
    jq("button").click(function(){
        jq("p").text("jQuery is still working!");
    });
});
