I have a HTML which contains a window.on("load") function. and placing that html in Tinymce 5. But its not rendering window.on("load") function. Following is my code
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<h1>Some content</h1>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(window).on("load",function() {
alert(1)
});
</script>
</body>
</html>
try something like this
<script>
const load = () => {
console.log("load event detected!");
}
window.onload = load;
</script>
Please check out this question. Probably you have faced the same problem. TinyMCE does not allow <script> elements by default due to security concerns (such as XSS attacks). But if you are sure you need them, the extended_valid_elements config option should help.
