I'm trying to figure out if this is even possible and if it is how? I want to dynamically add JS code to a page onload. The object is already created and I want to update the object in the updated code.
primary file contains:
var aa = {};    
aa.test ='orig';
var key = '111';
var stbi = document.createElement('script');
		 switch(key) {
		 case '111': 
		 	  stbi.src = "one.js";
			  break;
		  case '222':
		  	  stbi.src = "two.js";
			  break;
		  default:
		  	stbi.src = "three.js";
		  }

		  stbi.onload = function() {
		  document.head.appendChild(this);
		  }

Open in new window

and the test JS file (one.js) to be dynamically included contains:
aa.test = 'script one';
console.log('---->'+aa.test);

Open in new window

how would I accomplish this?

A quick one :
var script  = document.createElement("script");
script.src = "/path/to/one.js"; // path to your file
document.head.appendChild(script);

Open in new window


the same with jQuery :
$.getScript("/path/to/one.js");

Open in new window

you need to have the script tag too

<script>
aa.test = 'script one';
console.log('---->'+aa.test);
</script>
