How to best use 'this' when its unavailable

Question

say I create someObj like this

var someObj = function(){
  var self = this;
  //use this normally
  document.body.addEventListener('click',function(){
     //use self because this is unavailable
  },false)
}
new someObj();

In the event this is not the someObj which id like to use but in this case the body element. Is there a best practice way to get someObj or is declaring some self var like in the example considered any good?

Answer 1

In my experience, declaring something like 'self' is the easiest way to do it.

I would consider your code to be perfectly acceptable.

Answer 2

Using self seems fine to me.
