I need to run JavaScript code in iframe. But script with id \"us\" loaded after creating iframe. How to run this javascript in iframe?
Since you're not addressing the questions in the comments to better clarify what you are trying to do... I shall assume you are trying to access content IN your iframe FROM your parent page. Since the other answer should work fine if trying to run it from within the iframe.
On the parent page try something like:
$(function() {
$("#preview").load(function ()
$("#preview").contents().find(".test").click(function() {alert(true);});
});
});
*This assumes both parent and iframe are on the same domain.
