VistasUsing JQuery in Drupal 7
I'm writing my own Drupal 7 module, and like to use JQuery in it.
$('#field').toggle();
But I'm getting this error:
TypeError: Property '$' of object [object DOMWindow] is not a function
It seems that JQuery is not loaded. Otherwise $ should be defined.
Though I actually include it in the header:
<script type="text/javascript" src="http://rockfinder.de/misc/jquery.js?v=1.4.4"></script>
Do I have to do anything else to activate JQuery in Drupal? Is $ being overwritten by Drupal?
That's the website: http://rockfinder.orgapage.de

From the Drupal 7 upgrade guide:
Javascript should be made compatible with other libraries than jQuery by adding a small wrapper around your existing code:
(function ($) { // Original JavaScript code. })(jQuery);The $ global will no longer refer to the jquery object. However, with this construction, the local variable $ will refer to jquery, allowing your code to access jQuery through $ anyway, while the code will not conflict with other libraries that use the $ global.
You can also just use the 'jQuery' variable instead of the $ variable in your code.

According to Firebug, your jQuery file is being loaded:
But the $ is being overwritten by something else:
What you should do is encapsulate the use of the $ variable with a function that invokes itself using the jQuery object as it's first actual argument:
(function ($) {
// in this function, you can use the $ which refers to the jQuery object
}(jQuery));

Chances are your script is not initialized this way, you'll have to use Drupal.behaviors.YOURTHEMENAME
(function ($) {
Drupal.behaviors.YOURTHEMENAME = {
attach: function(context, settings) {
/*Add your js code here*/
alert('Code');
}
};
})(jQuery);
