Function not defined in javascript

Question

 window.onload = function(){
 var outerFn = function ( oParam ){
 return oParam; 
 }
 var v = OuterFn( 2 );
 alert('V :'+v);
 }

In this function i always get OuterFn not defined. Whats going wrong ??? Can somebody tell me.

Answer 1

OuterFn and outerFn are different things as JavaScript is case sensitive, try it with a small o. Ie:

window.onload = function(){
 var outerFn = function ( oParam ){
 return oParam; 
 }
 var v = outerFn( 2 );
 alert('V :'+v);
}

Answer 2

Your function is assigned to outerFn variable, so that's why you should call it:

var v = outerFn(2);

JavaScript is case sensitive.
