Detect Click into Iframe using JavaScript

I understand that it is not possible to tell what the user is doing inside an iframe if it is cross domain. What I would like to do is track if the user clicked at all in the iframe. I imagine a scenario where there is an invisible div on top of the iframe and the the div will just then pass the click event to the iframe.

Is something like this possible? If it is, then how would I go about it? The iframes are ads, so I have no control over the tags that are used.

As found there : Detect Click into Iframe using JavaScript

=> We can use iframeTracker-jquery :

$('.carousel-inner .item').each(function(e) {
    var item = this;
    var iFrame = $(item).find('iframe');
    if (iFrame.length > 0) {
        iFrame.iframeTracker({
            blurCallback: function(){
                // Do something when iFrame is clicked (like firing an XHR request)
                onItemClick.bind(item)(); // calling regular click with right context
                console.log('IFrameClick => OK');
            }
        });
        console.log('IFrameTrackingRegistred => OK');
    }
})

You can do this to bubble events to parent document:

$('iframe').load(function() {
    var eventlist = 'click dblclick \
                    blur focus focusin focusout \
                    keydown keypress keyup \
                    mousedown mouseenter mouseleave mousemove mouseover mouseout mouseup mousemove \
                    touchstart touchend touchcancel touchleave touchmove';

    var iframe = $('iframe').contents().find('html');

    // Bubble events to parent
    iframe.on(eventlist, function(event) {
        $('html').trigger(event);
    });
});

Just extend the eventlist for more events.

The following code will show you if the user click/hover or move out of the iframe:-

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Detect IFrame Clicks</title>
<script type="text/javascript">
    $(document).ready(function() {
        var isOverIFrame = false;

        function processMouseOut() {
            log("IFrame mouse >> OUT << detected.");
            isOverIFrame = false;
            top.focus();
        }

        function processMouseOver() {
            log("IFrame mouse >> OVER << detected.");
            isOverIFrame = true;
        }

        function processIFrameClick() {
            if(isOverIFrame) {
                // replace with your function
                log("IFrame >> CLICK << detected. ");
            }
        }

        function log(message) {
            var console = document.getElementById("console");
            var text = console.value;
            text = text + message + "\n";
            console.value = text;
        }

        function attachOnloadEvent(func, obj) {
            if(typeof window.addEventListener != 'undefined') {
                window.addEventListener('load', func, false);
            } else if (typeof document.addEventListener != 'undefined') {
                document.addEventListener('load', func, false);
            } else if (typeof window.attachEvent != 'undefined') {
                window.attachEvent('onload', func);
            } else {
                if (typeof window.onload == 'function') {
                    var oldonload = onload;
                    window.onload = function() {
                        oldonload();
                        func();
                    };
                } else {
                    window.onload = func;
                }
            }
        }

        function init() {
            var element = document.getElementsByTagName("iframe");
            for (var i=0; i<element.length; i++) {
                element[i].onmouseover = processMouseOver;
                element[i].onmouseout = processMouseOut;
            }
            if (typeof window.attachEvent != 'undefined') {
                top.attachEvent('onblur', processIFrameClick);
            }
            else if (typeof window.addEventListener != 'undefined') {
                top.addEventListener('blur', processIFrameClick, false);
            }
        }

        attachOnloadEvent(init);
    });
</script>
</head>
<body>
<iframe src="www.google.com" width="100%" height="1300px"></iframe>
<br></br>
<br></br>
<form name="form" id="form" action=""><textarea name="console"
id="console" style="width: 100%; height: 300px;" cols="" rows=""></textarea>
<button name="clear" id="clear" type="reset">Clear</button>
</form>
</body>
</html>

You need to replace the src in the iframe with your own link. Hope this'll help. Regards, Mo.

This definitely works if the iframe is from the same domain as your parent site. I have not tested it for cross-domain sites.

$(window.frames['YouriFrameId']).click(function(event){  /* do something here  */ });
$(window.frames['YouriFrameId']).mousedown(function(event){ /* do something here */ });
$(window.frames['YouriFrameId']).mouseup(function(event){ /* do something here */ });

Without jQuery you could try something like this, but again I have not tried this.

window.frames['YouriFrameId'].onmousedown = function() { do something here }

You can even filter your results:

$(window.frames['YouriFrameId']).mousedown(function(event){   
  var eventId = $(event.target).attr('id');      
  if (eventId == 'the-id-you-want') {
   //  do something
  }
});

Based in the answer of Paul Draper, I created a solution that work continuously when you have Iframes that open other tab in the browser. When you return the page continue to be active to detect the click over the framework, this is a very common situation:

          focus();
        $(window).blur(() => {
           let frame = document.activeElement;
           if (document.activeElement.tagName == "IFRAME") {
             // Do you action.. here  frame has the iframe clicked
              let frameid = frame.getAttribute('id')
              let frameurl = (frame.getAttribute('src'));
           }            
        });

        document.addEventListener("visibilitychange", function () {
            if (document.hidden) {

            } else {
                focus();
            }
        });

The Code is simple, the blur event detect the lost of focus when the iframe is clicked, and test if the active element is the iframe (if you have several iframe you can know who was selected) this situation is frequently when you have publicity frames.

The second event trigger a focus method when you return to the page. it is used the visibility change event.

see http://jsfiddle.net/Lcy797h2/ for my long winded solution that doesn't work reliably in IE

        $(window).on('blur',function(e) {    
            if($(this).data('mouseIn') != 'yes')return;
            $('iframe').filter(function(){
                return $(this).data('mouseIn') == 'yes';
            }).trigger('iframeclick');    
        });

        $(window).mouseenter(function(){
            $(this).data('mouseIn', 'yes');
        }).mouseleave(function(){
            $(this).data('mouseIn', 'no');
        });

        $('iframe').mouseenter(function(){
            $(this).data('mouseIn', 'yes');
            $(window).data('mouseIn', 'yes');
        }).mouseleave(function(){
            $(this).data('mouseIn', null);
        });

        $('iframe').on('iframeclick', function(){
            console.log('Clicked inside iframe');
            $('#result').text('Clicked inside iframe'); 
        });
        $(window).on('click', function(){
            console.log('Clicked inside window');
            $('#result').text('Clicked inside window'); 
        }).blur(function(){
            console.log('window blur');
        });

        $('<input type="text" style="position:absolute;opacity:0;height:0px;width:0px;"/>').appendTo(document.body).blur(function(){
                $(window).trigger('blur');
            }).focus();
