object expected error in IE only

this page runs fine in firefox but returns the horrible "object expected" error, and in the onload method it says
error 'imagePlaceholderNames ' is unexpected, what have i done wrong please.

i read on one website that IE could be doing things in the wrong order, but surely it does leave onload until the right time...

looks like your html markup got screwed up by the forum.

can you repaste it with the "Disable HTML in this message" checkbox checked.

Also version of IE is?

IE 7, sorry forgot that bit, not sure it did, but here it is again (just in case)

I was blind the first time I looked at it

for each (var imageName in orderedImageNamesArray){

JavaScript does not have a for each, it is just for

Actually, I think it does. It is just really new. I accidently used it myself too. And had to convert it to a for loop.

If I remember correctly, it was added to firefox at 1.5. And IE 7 definitely doesn't support it.

My Opinion: If it is not in JavaScript 1.5 it is not in JavaScript.

I think it is in JavaScript 1.6, too lazy to check Mozilla's site

sorry to be dense but just double checking that means it only has c style for loops
for(i=0;i<x;i++){

Yeah. After I got burned with it, I marked that whole section in the book as "stuff to not use"... I didn't go as far as "it doesn't exist" though...

No. The "for ... in" loop works just fine in IE7. It is the "for each ... in" loop that is new, and is not supported in IE7.

thanks glad i checked

thanks very much that worked,
i wondered what was diff about the foreach until i just tested it

produces the output 0,1,2,3
not image1,image2,image3,image4 as i was expecting

The for..in construct is most useful when iterating over the properties of an object. For arrays, you should be using the good old normal for loop.
