Organizing JavaScript code to be visible in Eclipse Outline

How should I organize my JavaScript code to be visible well in deep in the Eclipse JSDT's Outline View?

For example, if 开发者_开发百科I have a JS file containing the following content, Outline shows the one top level function only:

function topLevel() {
  var local1 = 1;
  var local2 = 2;
  function local() {};
}

You need to add the web perspective in the "Open Perspective" dialog
