What about doing something like
$each(arr, function(item) {
if (item && item.foo) item.foo();
})It's more robust and will mean that you can start indexing your arrays from whatever you want.

Indeed this code would cause an issue for me, since the issue is not due to referencing of the nonexistent item, rather inside the loop I do something like:$each(arr, function(item, i) { item.foo(); // this will throw an error on undefiled object and stop JS })My workaround by the way is to check weather i == 0 (this is a special array I use where I normally start at position 1).FF's implementation does actually jump over position 0 - starting at 1, that would be logical interpretation of "foreach" vs "for (i =0 ; i < smt.length ; i++)" - where I tell him to begin at position 0 explicitly.Cheers -- RomanOn Tue, Dec 15, 2009 at 1:18 AM, Aaron Newton <[email protected] <mailto:[email protected]>> wrote:Here is the code for forEach, implemented into browsers that do not implement it themselves: forEach: function(fn, bind){ for (var i = 0, l = this.length; i < l; i++) fn.call(bind, this[i], i, this); } as you can see, it loops over each item and calls your function, passing the array's value at i. This is undefined for your zero value. I don't know where IE would freak out on this (though it doesn't surprise me that it might). The code above references yourArray[index] that shouldn't throw an error...
