Not sure how to use jQuery noconflict function

I've been working on this site for the past two weeks and everything has been running smooth until now. I have conflicting javascripts and all though I know what method to use to solve the problem (jquery noconflict), I have no idea how to use it!

In my case, I have:

• a drop menu which uses the prototype js and a custom js
• and a contact form which uses a few jquery files for validation and error notification

The case is classic, they work fine separately but not together. Ive read a gang of websites and most point to the solution of using:

<script>

  jQuery.noConflict();

  // Use jQuery via jQuery(...)
  jQuery(document).ready(function(){
    jQuery("div").hide();
  });

  // Use Prototype with $(...), etc.
  $('someid').hide();

</script>

Im new to javascript, so I dont know what to do with this snippet.

This is my header:

    <script src="js/prototype.js"></script>
    <script src="js/drop-o-matic.js"></script>
    <script>

  jQuery.noConflict();

  // Use jQuery via jQuery(...)
  jQuery(document).ready(function(){
    jQuery("div").hide();
  });

  // Use Prototype with $(...), etc.
  $('someid').hide();

    </script> 

    <!--[if lt IE 9]>

 <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
 <![endif]-->

    <!-- <script src="http://code.jquery.com/jquery-latest.js"></script>
 <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.4/jquery-ui.min.js"></script>
 <script src="js/jquery.jigowatt.js"></script> -->


    <script>
    document.createElement("article");  
    document.createElement("footer");  
    document.createElement("header");  
    document.createElement("hgroup");  
    document.createElement("nav");
    document.createElement("aside");
    document.createElement("section");
    document.createElement("menu");
    document.createElement("hgroup");
 </script> 

I only have the prototype & drop-o-matic js in effect and the js files for the form is commented (just after IE comment).

The prototype & drop-o-matic are for a html5 nav (has no id's, just

        <nav>
            <ul>
                <li><a href="index.php" class="home">Home</a></li>
                ...
                ...

            </ul>
        </nav>

What should I do to make the scripts work together?

Thanks for the help.

First of all, you are calling jQuery.noConflict() before you even include the jQuery library! That definitely will not work. You must include jQuery script tag before calling noConflict...

<script src="js/prototype.js"></script>
<script src="js/drop-o-matic.js"></script>
<script src="http://code.jquery.com/jquery-latest.js"></script><!-- IMPORTANT -->
<script>
  jQuery.noConflict();
</script>

You can also give jQuery your own alias if you'd like...

var $j = jQuery.noConflict();

$j(document).ready(function() {
  $j("div").hide();
});

For more information, please read the API documentation regarding Using jQuery with Other Libraries

One good thing you can try with jQuery is use:

$jq = jQuery.noConflict();

and then instead of using $ or jQuery right your code with

$jq("document").ready(function(){

// rest of your jQuery code inside;

});
