How to load third-party javascript tag asynchronously which has [removed]

Question

We give out a piece of javascript tags such as which site owners put on their site like http://exa

Answer 1

How about instead of loading the script by appending a script element, you load the contents of the script URL with an AJAX call and then use eval() to run it in the global scope? Here's an example and I did test it to verify that it works:

Hello World

And here are the contents I had in the test.js file:

document.write("This is a test...");
alert("...This is a test alert...");
console.log("...And a console message.");

I made the AJAX request for the script synchronous so that it would be loaded exactly as if it were a regular embedded script tag. If you run it asynchronously, and the script uses document.write after the page has been fully rendered, it clears the DOM and then writes to it... Kind of annoying actually. Lemme know if this works for you. :)
