jQuery has a method, called .contents(), that when used on an iframe
element returns the document of the iframe.
// Get a reference to the iframe document
var iframeDoc = $('#inviteFrame').contents().get(0);
Now you can bind an event to it, get the dimensions, get styles of various elements, etc:
// Get width of iframe document
$(iframeDoc).width();
// Get height of iframe document
$(iframeDoc).height();
// Bind event to iframe document
$(iframeDoc).bind('click', function( event ) {
// do something
});
// Get the style of an element in the iframe
$('div', iframeDoc).css('backgroundColor');
