Passing variables to windows

     



Passing variables in javascript works very similar to the PowerBuilder method.
When a window is opened, a variable is assigned to it. Using dot notation, a
variable within the window can be assigned a value. Note that the variable does
not have to be declared within the calling window; it is created
at runtime, just like all other javascript variables. Here is an example:






  w_lookup = window.open("tttlu.html","w_tttlu",
     "toolbar=0,menubar=0,location=0,status=0,height=470,width=630") ;
 
  w_lookup.w_tttnew = parent;  /* allow window to refer to this window */
  w_lookup.asset_id = 12345;   /* int value  */
  w_lookup.tnt_code = "NTRS";  /* char value */
 
These three variables can be accessed within the window w_lookup, as follows:
  newvar   = asset_id ;
  w_tttnew.f_processcode(tnt_code);
 
Note how the calling window's function is called.
