Use the jQuery contents() method
If you try to detect or capture a click event inside an iframe simply using jQuery click() method it will not work, because iframe embed a web page within another web page. However, you can still do it on the same domain utilizing the jQuery contents() and load() method.
The following example will display an alert message whenever you click inside the iframe.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Detect Click into iFrame</title>
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<style>
body{
padding: 30px;
}
iframe{
width: 100%;
height: 200px;
border: 2px solid #ccc;
}
</style>
<script>
$(document).ready(function(){
$("iframe").load(function(){
$(this).contents().on("mousedown, mouseup, click", function(){
alert("Click detected inside iframe.");
});
});
});
</script>
</head>
<body>
<iframe src="/examples/html/table-layout.php"></iframe>
</body>
</html>
