How could a form without submit node be submitted?

Hi, there,
Please take a look of http://gsx.apple.com. When you look at the source of the page, you'll find the "key" element of "Log In" is just a image, like this:
<TD ALIGN=left WIDTH="50%"><input border="0" type="image" name="1.Continue" src="/AppleConnect/US-EN/BtnGSXLogin.gif"></TD>

My question is that there's no "onclick" to activate a javascript and no "submit" type input but it should belong to a form with "post" method to submit it. So how could it (the image) response to my click action to finish the login action?

Thanks.

Inputs of type image are the same as submit buttons, only that they use an external image.

And FYI: There doesn’t need to be an onclick event handler (or any event handler) in the HTML to invoke a JavaScript function. Actually the best way is to keep scripts out of the HTML and invoke them from an external file, using the DOM to access/address elements.

Ah... yes! Thanks!
For the "keep scripts out of the HTML..." issue, do you mean put all scripts into a "xxxxx.js" file and include it in HTML file like this: <script src="xxxxx.js">?

I think he means like this:


someElement.onclick = function() {
alert('You clicked me!');
}

I think he means like this:


someElement.onclick = function() {
alert('You clicked me!');
}



or better still use event listeners for JavaScript and attachEvent for JScript instead of using event handlers at all.

I think he means like this:


someElement.onclick = function() {
alert('You clicked me!');
}


Oh, I see.
