I need to develop a page that shows how the method adopNode () works, from what I read it basically removes a node from an external page and loads it into the current document. This is my code, but the H1 tag element is not loaded into the current page:
<html>
<body>
<!-- Carrega página com um elemento de tag H1 -->
<iframe src="ex2.html" style="height:380px;width:520px;"></iframe>
<button onclick="myFunction()">Try it</button>
<script>
function myFunction() {
var frame = document.getElementsByTagName("IFRAME")[0];
var h = frame.contentWindow.document.getElementsByTagName("H1")[0];
var x = document.adoptNode(h);
document.body.appendChild(x);
}
</script>
</body>
</html>
