addEventListener to iFrame

问题

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?

回答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'); 
     });
 });

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');
}

回答3:

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

Try this. Works in jsfiddle. Enjoy.

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>
