Hi guys
I'm trying to learn more about javascript at the moment and am trying to fire an alert every time a form field is focused on.
I've created this code.
I have two problems:
Firstly, the alert fires correctly on the first input... however, when I press OK, it keeps firing! how do I make it only fire once?
Second problem, how can I make it fire on ALL inputs? You'll see I've done the following: formfields[0]. with the [0] indicating the first form input. However, I've only done this, as without selecting one input, it doesn't work at all...
Any help would be greatly appreciated

alert(this.id);

<body onload="setup()">I have two problems:
