How to avoid conflict between JQuery and Prototype

If a page has both JQuery and Prototype then I got conflict. There is a option to disable $ sign for JQuery so there is no conflict but, I have to use keyword JQuery instead of $.

I wonder if there is any option for Prototype to solve this conflict. Is there any way to use both libraries without compromising their benefit or short keyword?

As far as I know, it is not a good idea to use multiple JS library for same page; but it may be helpful for sometimes.

How can you avoid the in jQuery from clashing with the same name used by some other JS library?

Thus, if you are using another JavaScript library that uses the $ variable, you can run into conflicts with jQuery. In order to avoid these conflicts, you need to put jQuery in no-conflict mode immediately after it is loaded onto the page and before you attempt to use jQuery in your page.

Can I use both JavaScript and jQuery together?

jQuery is a JavaScript library, so it operates on top of JavaScript. It cannot exist on its own, so you can't use one over the other. You can use just JavaScript or JavaScript and jQuery. jQuery was introduced to make development with JavaScript easier.

Why do we use the no conflict () method in jQuery?

noConflict() method to give control of the $ variable back to whichever library first implemented it. This helps us to make sure that jQuery doesn't conflict with the $ object of other libraries. // Import other Library // Import jQuery Library $. noConflict(); // Code that uses other library's $ can follow here.

What is jQuery no conflict?

The noConflict() method releases jQuery's control of the $ variable. This method can also be used to specify a new custom name for the jQuery variable. Tip: This method is useful when other JavaScript libraries use the $ for their functions.

Use the noConflict method for jQuery and assign it to a new (short) variable. Use the new variable wherever you would have used the $ for jQuery.

var $j = jQuery.noConflict();

$j(function() {
    $j('#selector').each( .... );
});

or, if you don't need to mix Prototype/jQuery you can wrap all of your jQuery code in an anonymous function.

(function($) {
    // $ sign here is a parameter, which is set to jQuery 

    $(function() {
        $('#selector').each( .... );
    });
})(jQuery);
