One method of preventing a function from running more than once is to 
set a global variable the first time the function is called, and 
refuse to run if that variable is set:

         var bInitialized = false;
         ...
         function DoSomething()
         {
                         if (bInitialized) return;
                 bInitialized = true;

                 ...
         }
