How do I acces iframe with Jquery

I have Google in an iframe. I want to have some control over the input so I tried:

  $('#iframeID').contents().find('input').keydown(开发者_StackOverflow中文版function () {

     $(".SomeDiv").hide();

 });

Why isn't this working?

This is why you can't do this.

It's hard to answer the question without the underlying code, but have a look at this forum thread. At the bottom is a jQuery example, in which the same problem as you have is solved with jQuery.

You cannot access the iframe content which is in a different domain than its parent unless you map the domain which mostly is not allowed in all the browsers due to security reasons.
