Faster Lookup code

Faster Lookup code

Perhaps more JS than jQuery but looking for a faster option than a long if else statement code. Perhaps easier to manage.

I have a menu system which depending on the ID if the list item clicked calls a ajax page.

Here's how I'm managing it now 

Is there a way I can do it where I just maintain an index of ID's and pages?

  1. $( document). ready( function() {

        
       $( ".menu-li"). click( function( e){
         if ( $( this). attr( "id") ==  'my-btn'){

           $. ajax({ url:  "page-content/mypage.php",  success :  function( result){
             $( "#main-bdy"). html( result);
          }});
