this code works in google chrome, but not in firefox.

Code:

function merge(obj1, obj2) {
 var a ={};
  for (var p in obj1) {
    try {
      // Property in destination object set; update its value.
      if ( obj1[p].constructor==Object ) {
        a[p] = merge(a[p], obj1[p]);

      } else {
        a[p] = obj1[p];

      }

    } catch(e) {
      // Property in destination object not set; create it and set its value.
      a[p] = obj1[p];

    }
  }
    for (var p in obj2) {
    try {
      // Property in destination object set; update its value.
      if ( obj2[p].constructor==Object ) {
        a[p] = merge(a[p], obj2[p]);

      } else {
        a[p] = obj2[p];

      }

    } catch(e) {
      // Property in destination object not set; create it and set its value.
      a[p] = obj2[p];

    }
  }

  return a;
}
var d=function(){'c';}
var a ={a:{b:'c'},b:'c'}
var b ={c:a,d:d};
var c = merge(window,b);

WHY?!?!?!?!?!?!?!?!?!?!?!?!??!?!?!?!

Have you used Firebug, set break points and walk through the code to see where it fails? Add watches to see what the variables are.

it screws up at

Code:

    } catch(e) {
      // Property in destination object not set; create it and set its value.
      a[p] = obj1[p];

    }

it says

Error: uncaught exception: [Exception... "Operation is not supported" code: "9" nsresult: "0x80530009 (NS_ERROR_DOM_NOT_SUPPORTED_ERR)" location: "file:///C:/Program%20Files/a%20free%20javascript%20editor/YaldexTemp$$$8.htm Line: 26"]
