how to add a js condition

Hi

I want to write a condition in JS that will result in adding an external js.开发者_如何学C

For example if the condition is x > 2 and it is true then i want it to load a different external js file but if its false then load another js file.

How can i write it?

Thanks

  var fileref=document.createElement('script')
  fileref.setAttribute("type","text/javascript")
  if (x > 2){
     fileref.setAttribute("src", "/js/file1.js")
 }else{
     fileref.setAttribute("src", "/js/file2.js")
 }
 document.body.appendChild(fileref);

you can write:

if(conditon)
   $('body').append("<script src='whatever'><" + "/script>");
