The contentWindow property returns the Window object of an HTMLIFrameElement. You can use this Window object to access the iframe's document and its internal DOM. This attribute is read-only, but its properties can be manipulated like the global Window object.
HTMLIFrameElement.contentWindow
Value
A Window object.
Examples
var x = document.getElementsByTagName("iframe")[0].contentWindow; //x = window.frames[0]; x.document.getElementsByTagName("body")[0].style.backgroundColor = "blue"; // this would turn the 1st iframe in document blue.
