Embed javascript code in iframe

Embed javascript code in iframe

I need to embed this script in iframe. But if i embed it then output shown
is blank.
But without iframe it's giving proper output.
My script code :
<script type="text/javascript"
src="//akhilesh.worketc.com/v3.0/js/WebForms.js">
</script>
<script type="text/javascript">
RenderWebForm({"TemplateID":2,"Domain":"akhilesh.worketc.com","UseCustomCSS":false,"LoadingMes
sage":"Please wait"});
