javascript jquery events mouse

Solution 1

This will work:

 $('#myIFrame').load(function(){
     //then set up some access points
     var contents = $(this).contents(); // contents of the iframe
     $(contents).find("body").on('mouseup', function(event) { 
         alert('test'); 
     });
 });

Solution 2

If you just want a plain vanilla Javascript way, you can use the following:

var iframe = document.getElementById('myIFrame');
iframe.contentDocument.body.addEventListener('mouseup', Handler);

function Handler() {
    alert('works');
}

Solution 3

iframe.contentWindow

const iframe = document.getElementById('iframeId');
iframe.contentWindow.body.addEventListener('click',() => console.log('click));

Mind the cross-origin policy

Event bubbling will be allowed only if frames have the same origin. Unless you will get next error (Chrome):

Blocked a frame with origin "http://example.com" from accessing a cross-origin frame

Solution 4

Try this working on chrome, just tested

As per my knowledge, Iframe must be from same domain.

<!DOCTYPE html>
<html>
<head>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
    <title> - jsFiddle demo</title>
    <script type='text/javascript' src='//code.jquery.com/jquery-1.8.3.js'></script>

    <script type='text/javascript'>
        $(window).load(function () {            
            var $frame = $("#myIFrame");
            $frame.contents().bind("mouseup", function (e) {
                alert('inside');
            });
        });
    </script>
</head>
<body>
    <iframe id="myIFrame" src="/WebForm4.aspx" style="position:absolute; width:500px; height:500px;left:0px; top:50px"></iframe>
</body>
</html>

Solution 5

$($("#iframeid").contents()[0], window).find('body').bind("mouseup", function(e) {
    alert("works");
});

Try this. Works in jsfiddle. Enjoy.

I'm tryin to add event listener to mouseup inside iframe object:

$("#myIFrame").contents().find("body").bind("mouseup", function() {
    //e.preventDefault(); //doesn't make difference
    alert('inside');
});

This doesn't work. Any ideas?

it wont work on jsfiddle, because it mark that script as CDATA. Try this on your local machine.

Sometimes contentDocument does not exist, so try contentWindow in stead of it. Example: w3schools.com/jsref/…

Yes, in Chrome 79, this code worked for me only when changing it to iframe.contentWindow.document.addEventListener('mouseup', Handler);

Thanks 👌 Your approach works perfectly, but I add to use 'contentDocument' instead of 'contentWindow'. iframe.contentDocument.body.addEventListener('click', () => console.log('click'));

Then how we can approach for cross domain origin.
