Use JavaScript to prevent a later `[removed]` tag from being evaluated?

This is a bit of an oddball use case, but I have my reasons:

Given your specific requirements set, this is actually quite simple and should work completely cross-browser. It does require however, that first.js immediately precedes second.js without anything between them except white space.

First, let's assume that the HTML looks like this:

  
    
    
    
    
    
  
  
    
Lorem ipsum dolor sit amet ...
    Run Func()
  

I've removed the setTimeout because that can cause func() to run before start.js runs causing a "loadSecond is not defined" error. Instead, I've provided an anchor to be clicked on to run func().

Second, let's assume that second.js looks like this:

document.body.appendChild(document.createTextNode("second.js has run. "));
if (window.meaningOfLife !== 42) {throw new Error();}

Here, I've just added a line to append some text to the document body, so that it is easier to see when second.js actually runs.

Then the solution for first.js is this:

function loadSecond()
{
    var runSecond = document.createElement("script");
    runSecond.setAttribute("src", "second.js"); 
    document.body.appendChild(runSecond);
}

document.write("
