It will be much easier to put a JS function in the page that's loaded into the iframe and then from the parent page you can call that function.

You can put a JS function in the page that shows up in the iframe and then call that function from the parent.

JavaScript

$("#iframe1")[0].contentWindow.functionInPage();

and then in that page you have easy access to all the controls.

what should i put inside the function that being's declared inside the child page(the page that shows up in iframe, i want to access specific controls of that page from parent page, so should i have the function in child page access that controls, then use it from parent page ?

Yes. Child page already knows about all controls so it will be easier to do what you need to from it's point of view.
