Searching within an iFrame for an element using the getElementById method

Hey, I'm working with an iframe and trying to reference a CSS element that is located on the source page. Here's the iframe code:

<iframe id="CPHNavBar_TBDC081D1008_frameSticky" src="/stickyserviceavailabilitycheck"></iframe>

I want to select this CSS element when on the source page:

document.getElementById("ContentPlaceHolder1_C001_btnSMBAddressCheckYes");

Is it possible to reference the CSS element from the page hosted within the iframe?

Answer №1

Thanks to the concept of the Same Origin Policy, when it comes to web pages that don't have the same domain name and port number, one page is restricted from altering the Document Object Model (DOM) or executing JavaScript on another page. This restriction is commonly attempted through the use of the <iframe> element. The Same Origin Policy also impacts XMLHttpRequest.
