Sometimes you may have to load the scripts or content inside
and iframe. This will be helpful especially if you are loading an ad or video
on a web page and do not want to slow down the whole web page. Given below is
an example on how to load content inside an iframe asynchronously.
<iframe id="myiframe" height="300" width="700"></iframe>
<script>
window.setTimeout(setIframeContent,1000);
function
setIframeContent() {
//set content or script
var html = '<body><div>my content</div><scr' + 'ipt>alert("test")</' + 'script></body>';
//get reference to iframe and load the content to iframe
var iframe =
document.getElementById("myiframe");
iframe.contentWindow.document.open();
iframe.contentWindow.document.write(html);
iframe.contentWindow.document.close();
}
</script>
