How to capture click on iframe using javascript [duplicate]

Question

How to capture click on iframe using javascript.

I'm using this code:

document.getElementsByClassName('pin').contentWindow.document.body.onclick = 
function() {
  alert("iframe clicked");
}

But it is not able to capture any click of the iframe. I can only use javascript. I'm getting this error "SecurityError: Blocked a frame with origin"

getElementsByClassName returns a NodeList which doesn't have a contentWindow property. Either try document.getElementsByClassName('pin')[0] or walk on the list. — haim770

-1

var i = 0; 
//i represents the exact node since obtaining node by class name gives array of nodes.
var iframe = document.getElementsByClassName('pin')[i].contentWindow;

or

var iframe = document.getElementById("iframe_id").contentWindow;

iframe.document.body.onmousedown = 
function() {
  alert("iframe clicked");
}
