[SOLVED] Basic Varible Stuff

[rhyspaterson]

Hey guys,

 

Still quite to new to JavaScript (and JSON notation) and just need a bit of basic help:

 

My pseudo code here (which works):

 

var dController = {
      
   a: function() {

      }
   , 
      
   b: function() {

      }
   ,
      
   c: function() {

      }
   , 
   
if (document.getElementById) {
   addEvent(window, 'load', dController.a); 
   /* This can be replaced with either b or c to change what happens */
   }

 

However, if i now have a variable which tells me which function needs to be run, lets call it 'state', how can i also use that in my addEvent function. I.e, if 'state' is set to 'c', the my addEvent will parse dController.c!

 

var dController = {
      
   state : 'c', 
      
   a: function() {

      }
   , 
      
   b: function() {

      }
   ,
      
   c: function() {

      }
   , 
   
if (document.getElementById) {
   addEvent(window, 'load', dController.?);
   }

 

Obviously i cant go dController.state (as it won't work). Any ideas?

 

Cheers lads!

Obviously i can use the EVAL command, but i would rather not.. is it possible to use the square bracket notation here?

Hokay square brackets did work in the end. Needed to include the dController variable twice 

 

if (document.getElementById) {
   addEvent(window, 'load', dController[dController.state]);  
}
