Some Things to know about IE 7

When using javascript in IE 7, you don't need to use getElementById

Thus in IE 6 you would do:

<script>
var city = document.getElementById('city');
alert(city.innerHTML);
</script>

And in IE 7 you can do

<script>
alert(city.innerHTML);
</script>

city is automatically an object pointing to the HTML tag with the id of that name.

This also means that if you accidentally use a variable with the same name as an id of an element, you will get errors.

I'm sure this gives rise to some kind of security flaw.
