TypeError: 'undefined' is not a function (evaluating '$(document)')

Question

Wordpress uses jQuery in noConflict mode by default. You need to reference it using jQuery as the variable name, not $, e.g. use

jQuery(document);

instead of

$(document);

You can easily wrap this up in a self executing function so that $ refers to jQuery again (and avoids polluting the global namespace as well), e.g.

(function ($) {
   $(document);
}(jQuery));

Use jQuery's noConflict. It did wonders for me

var example=jQuery.noConflict();
example(function(){
example('div#rift_connect').click(function(){
    example('span#resultado').text("Hello, dude!");
    });
});

That is, assuming you included jQuery on your HTML

<script language="javascript" type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>

Use this:

var $ =jQuery.noConflict();

Try this snippet:

jQuery(function($) {
  // Your code.
})

It worked for me, maybe it will help you too.
