Executing Scripts inserted with InnerHTML
Inserting Script Tags on Page Load
I have noticed that when using .innerHTML to add script elements like
<script type="text/javascript" src="source.js"></script>
or
<script type="text/javascript"> // embedded code here </script>
The scripts do not execute. They seem inactive or "dead". Is there a way to manually initiate their execution?
To properly add JavaScript to your HTML document, you should place the script inside the head tag like this:
var head = document.getElementsByTagName("head")[0];
var newScript = document.createElement('script');
newScript.type = 'text/javascript';
newScript.src = 'http://www.somedomain.com/somescript.js';
head.appendChild(newScript);
(This is a common practice, and the code snippet was sourced from: )
As a side note: If you are using jQuery, be cautious with appending scripts using the following method:
<script>
[....]
$( "head" ).append( "<script src='myScript.js'></script>" );
[....]
</script>
It's important to note that this approach does not work as intended because the JavaScript parser will stop parsing when it encounters the first </script> tag.
