Hi,

You just need to have something like this 

SyntaxEditor Code Snippet

"<script>
$( document ).ready(function() {
  alert('Hello " + Input + " World!')
});
</script>"

This if you are using expressions. On RunJavascript Action is the same thing. If you have the JS in the webblock advance property you need to use the expression or the action to call the action there.

Regards,

Marcelo
