Fw: [Javascript] Fw: hide other divs

 ok, i splitted the if cases for further handling in the function,
 but it should still work the way you supposed it, or?

  divElementsId = divElements[i].getAttribute("id");

        if(divElementsId && divElementsId.substring(0,6) == mySubstring)
  {
 ...
 }

 IE still works fine but FF again breaks off:(

The reason why you don't need getAttribute is simple the id attribute is an 
"built in" attribute that mean that all browser will recognise 
mydiv.attribute if you create a custom attribute like eg: <div order="1"> at 
this point you need getAttribute to pick it up in all browser simply because 
some browser won't recognise mydiv.order as an attribute.

so i should not use an own attribute?! sorry, didn't wuite get the 
solution:/
