Question

I know that I can run an external Javascript file from within HTML with the following syntax:

<script type="text/javascript"
src="http://somesite.com/location/of/javascript.js">
</script>

This will result in http://somesite.com/location/of/javascript.js being run the moment the browser reads that line of the HTML.

But is there a way I can run an external Javascript file from within Javascript? Something like:

if (x == 1)
{
 run this! -> http://somesite.com/location/of/javascript.js;
}

Obviously that’s not valid code. But I can’t find any example of what might be the right way to do this (if it exists), because all the help text I find with Google searches tell me how to run Javascript from within HTML

I know that I can include a Javascript file and then call functions within it. However, in this situation, I do not have any control over http://somesite.com/location/of/javascript.js, and it is designed to execute the moment it is called. I can’t change how it works, so I need to figure out how to call it at the right time in the right way.

Is there a way I can get it to be called and executed immediately depending on a conditional statement?

Yes, in Pure Javascript you can Load javascript dynamically

var s = document.createElement("script");
s.src = "test.js";
document.body.appendChild(s);
