<script src = "..."> </script> via .innerHTML add

Question

JavaScript dynamically adds script tag with SRC ATTRIBUTE via innerHTML

For example:

var banner = '<script src="http://example.com/script.js"><\/script>'; document.getElementById("examplediv").innerHTML = banner; 

I see a script tag in a DIV with id = "examplediv", but script.js is not loading.

The variable banner can contain different data (HTML code), and I cannot use document.createElement ('script') ;, setAttribute, etc.

Without any libraries like jQuery.

How can I load a script file and execute its contents?

PS Excuse me for my English.
