IFrame button click event

Question

I\'m trying to attach an eventlistener to the \"click\" event of a button on a page in an IFrame. The page in the iframe belongs to the same domain as the parent window.

Answer 1

window.frames is an array-like object, so its elements can be accessed by indexes only.

You should loop through them, and check their id, e.g.:

var frame; for(i = 0; i < frames.length; i++) {
    frame = frames[i];
    if (frame.id === 'iframe_id') {
         frame.document
              .getElementById("button_id")
              .addEventListener("click",functionToRun,false);
    }
}
