IFrame button click event

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.

window.frames["iframe_Id"].document.getElementById("button_id").addEventListener("click",functionToRun,false);

The above sample is not working for me. It could just be a a syntax error in my actual code but I wanted to see if this is the general idea.

Note: I found plenty of examples on adding the click event to the entire Iframe but I'm not sure it works the same for buttons within the Iframe.

Using jQuery:

$("#iframe_Id").contents("#button_id").click(functionToRun);

Or without jQuery:

document.getElementById("iframe_Id").contentWindow.document.getElementById("button_id").addEventListener("click", functionToRun, false);

This will only work if the iframe meets the same origin policy.

window.frames["iframe_Id"].contentWindow.document.getElementById("button_id").addEventListener("click",functionToRun,false);

                              ^

The contentWindow property.

From the DOM iframe element, scripts can get access to the window object of the included HTML page via the contentWindow property.

Have you tried executing the event in the "capturing" vs. "bubbling" phase?

document.getElementById("iframe_Id")
 .document.addEventListener("click", functionToRun, true);

Note the true instead of false as the final parameter.

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);
    }
}
