How to detect a click event on a cross domain iframe
var myConfObj = {
iframeMouseOver : false
}
window.addEventListener('blur',function(){
if(myConfObj.iframeMouseOver){
console.log('Wow! Iframe Click!');
}
});
document.getElementById('YOUR_CONTAINER_ID').addEventListener('mouseover',function(){
myConfObj.iframeMouseOver = true;
});
document.getElementById('YOUR_CONTAINER_ID').addEventListener('mouseout',function(){
myConfObj.iframeMouseOver = false;
});

Hi,
Solve the problem in this way for mobile and desktop.

$(document).ready(function()
 {
	window.addEventListener('blur',function(){		
	    if (document.activeElement instanceof HTMLIFrameElement) {
                //Click in Iframe.
	    	tagueoFocusForm("campo captcha no robot");
	    }
	});	
});

window.addEventListener('blur',function(){
if (document.activeElement instanceof HTMLIFrameElement)
some code}

This content.js code is not working for firefox though it is working for chrome. The web page is consisted of multiple iframes. Any suggestion.

For me, adding a 0 second timeout to @Pretorians suggestion made it work in Firefox. The problem seems to be that, at the time Firefox fires the blur event, it has not yet updated the document.activeElement, so it evaluates to false.

	window.addEventListener('blur',function(){	
            window.setTimeout(function () {	
	        if (document.activeElement instanceof HTMLIFrameElement) {
	    	    console.log("iframe click");
	        }
             }, 0);
	});

As alucidwolf, I am looking for a way to access a button inside the iFrame and trigger a click event when that button is clicked inside the iFrame that is on another domain.

Has anyone had success taking it this far?

Michael

Wow nice trick 👍

This solution is not working for FF v62, because when you click on iframe and redirecting to a new window/tab, blur event in not thrown. Unfortunately I didn't fund any workaround yet.

Here is how I track iframe click for FF/Chrome:

function () {
    const state = {};

    (function (setup) {
        if (typeof window.addEventListener !== 'undefined') {
            window.addEventListener('load', setup, false);
        } else if (typeof document.addEventListener !== 'undefined') {
            document.addEventListener('load', setup, false);
        } else if (typeof window.attachEvent !== 'undefined') {
            window.attachEvent('onload', setup);
        } else {
            if (typeof window.onload === 'function') {
                const oldonload = onload;
                window.onload = function () {
                    oldonload();
                    setup();
                };
            } else {
                window.onload = setup;
            }
        }
    })(function () {
        state.isOverIFrame = false;
        state.firstBlur = false;
        state.hasFocusAcquired = false;

        findIFramesAndBindListeners();

        document.body.addEventListener('click', onClick);

        if (typeof window.attachEvent !== 'undefined') {
            top.attachEvent('onblur', function () {
                state.firstBlur = true;
                state.hasFocusAcquired = false;
                onIFrameClick()
            });
            top.attachEvent('onfocus', function () {
                state.hasFocusAcquired = true;
                console.log('attachEvent.focus');
            });
        } else if (typeof window.addEventListener !== 'undefined') {
            top.addEventListener('blur', function () {
                state.firstBlur = true;
                state.hasFocusAcquired = false;
                onIFrameClick();
            }, false);
            top.addEventListener('focus', function () {
                state.hasFocusAcquired = true;
                console.log('addEventListener.focus');
            });
        }

        setInterval(findIFramesAndBindListeners, 500);
    });

    function isFF() {
        return navigator.userAgent.search(/firefox/i) !== -1;
    }

    function isActiveElementChanged() {
        const prevActiveTag = document.activeElement.tagName.toUpperCase();
        document.activeElement.blur();
        const currActiveTag = document.activeElement.tagName.toUpperCase();
        return !prevActiveTag.includes('BODY') && currActiveTag.includes('BODY');
    }

    function onMouseOut() {
        if (!state.firstBlur && isFF() && isActiveElementChanged()) {
            console.log('firefox first click');
            onClick();
        } else {
            document.activeElement.blur();
            top.focus();
        }
        state.isOverIFrame = false;
        console.log(`onMouseOut`);
    }

    function onMouseOver() {
        state.isOverIFrame = true;
        console.log(`onMouseOver`);
    }

    function onIFrameClick() {
        console.log(`onIFrameClick`);
        if (state.isOverIFrame) {
            onClick();
        }
    }

    function onClick() {
        console.log(`onClick`);
    }

    function findIFramesAndBindListeners() {
        return Array.from(document.getElementsByTagName('iframe'))
            .forEach(function (element) {
                element.onmouseover = onMouseOver;
                element.onmouseout = onMouseOut;
            });
    }
}

What if I have 4 iframes. I cant figure out how to separate them, when I click on one of them the function executes for all of them. My function is it zooms in the iframe when clicked but when i click 1 all of them get zoomed

ANN0Y1NGHACKER, here's how I targeted a specific iframe for a google captcha:

var frames = Array.from(document.getElementsByTagName('iframe'));
var recaptchaWindow;

frames.forEach(function(x){
if (x.src.includes('google.com/recaptcha/api2/bframe') ){
recaptchaWindow = x.parentNode.parentNode;
};
});

JQuery version

        var iframeMouseOver = false;
	$("YOUR_CONTAINER_ID")
		.off("mouseover.iframe").on("mouseover.iframe", function() {
			iframeMouseOver = true;
		})
		.off("mouseout.iframe").on("mouseout.iframe", function() {
			iframeMouseOver = false;
		});

	$(window).off("blur.iframe").on("blur.iframe", function() {
		if(iframeMouseOver){
			$j("#os_top").click();
		}
	});

Thanks for this.

When we have cross-domain iframe, this will stop triggering the click on the iframe it self.
Any idea how to trigger both the parent blur event and the iframe click event?

@azu-kodix

If page has multiple iframes then event will only fire the first time, unless you return focus to the page. Hmm..

As far as I can test this seems to work in Chrome and Firefox, but not in Safari. Anyone else got a workaround to get this working in Safari?

Also I would like to mention that if you add window.focus(); the user then don't have to click outside the iFrame themselves before it can register again a 'click' on the iFrame.

window.addEventListener('blur', function () {
    window.setTimeout(function () {
        if (document.activeElement == document.querySelector('your_iframe_selector')) {
            //handle click
            window.focus();
        }
    }, 0);
});

Correction! It does work in (desktop) Safari. I needed to clear the browser history and after that my 'HTML/CSS/JS iframe click wizardry' did what it was supposed to do.
