Is it possible to access the jQuery lib from an iframe, when it's included in the parent window only? I have a parent window which loads (sometimes hundreds) of iframes. In each iframe I want to execute some jQuery functions. I can only get this working if I define the lib in each iframe, using : 

```
<script src="/jquery.min.js" type="text/javascript"></script>

```

However, I would prefer, for faster loading, that I include the above script tag only in the parent window, then from each child/iframe access the parent's library to execute a function that affects the iframe.

Thanks for the response. Here is what I have in the child frame : 

```
&lt;script>
var $ = parent.jQuery;

$(this, document).ready(function(){
    var step = 0.2;
    $('body', document).css('MozTransform','scale(0.2)');
});

&lt;/script>

```

And what I'd expect is that once the child's doc is "ready" it would shrink itself down to 20%. Except its not working. Is it possible, or should I try add the child's code to the parent doc and assign ids to each frame, then loop through them.

Using 
 $( document ).ready(function(){
 $('body').css('MozTransform','scale('

results in the parent window scaling down. I'm wanting to scale down the iframe.
