Function pointers in javascript using django

Question

Is this a valid function pointer code below,

In views ,

    def change(request):
       dict={}
       function_ptr="create()" 

        dict.update({'function_ptr' : function_ptr})
       return render_to_response('mpjt/create.html',context_instance=RequestContext(request,{'dict': dict}))

In create.html

      $(document).ready(function() {
     var a = '{{dict.function_ptr}}'

     func_ptr(a);

      function create()
     {
       alert('got respponse');
      }
     });

Thanks..

No.

Pass function_ptr='create' in your python code and use the following in your JavaScript:

var func_ptr = window[{{ dict.function_ptr }}];

This must be done AFTER the function create() has been defined! If you want to do it earlier, you could do it with an anonymous function:

var func_ptr = function() {
    return window[{{ dict.function_ptr }}];
}
