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

You can support script injection the correct way by intercepting calls to document.write in this way:

document.writeText = document.write;

document.write = function(parameter) {
    if (!parameter) return; 
    var scriptPattern = /

Obviously this can be condensed down a bit further, but the variable names are included for clarity.
