How to Safely Include Dynamic Scripts with Uncertain Src Content?

Including Dynamic Scripts with Uncertain Src Content

Question:

How can I dynamically add a script tag with an unrestrained src that may contain document.write calls?

Explanation:

In scripts with uncontrolled src attributes, the content may include document.write calls, which can interfere with traditional script tag loading.

Solution:

To circumvent this issue, create a new script element manually:

var my_awesome_script = document.createElement('script');
my_awesome_script.setAttribute('src','http://example.com/site.js');

Append the newly created script element to the head of the document:

document.head.appendChild(my_awesome_script);

This method ensures that the script is loaded asynchronously without interfering with the document flow.
