Using images as submit buttons in a form

A few hints.

1. use
<A HREF="javascript:;" onClick="someFunction(); return false">call function</A>
otherwise any animations on the page stop and the cursor in Netscape does not reset from the hourglass until moved

2. LY: use slightly more descriptive function names - I know prakashk is a perl expert and probably LIKES short names, but it does make it harder to see what is going on...

3. Pass the form object from where it is called. That way the function does not have to care about what the name is:

<form name="formA">
<input type="text" name="field1" value="">
<input type="text" name="field2" value="">
<Input Type="TextArea" Name="Output">
</form>

<a href="javascript:;" onClick="processForm(document.formA);return false;"><img src="img1"></a>

where processForm looks like this:

processForm(theForm) {
   theForm.Output.value = parseInt(theForm.field1.value) + parseInt(theForm.field2.value);
}

or
<a href="javascript:;" onClick="processForm(document.formA.field1.value,document.formA.field1.value,document.formA);return false;"><img src="img1"></a>

where processForm looks like this:

processForm(val1,val2,theForm) {
   theForm.Output.value = parseInt(val1) + parseInt(val2);
}

PS: Alternative to one image submit:
<A HREF="javascript:;" onClick="document.formA.submit(); return false"><IMG SRC.....></A>

Re: Your comments..

1. Good points, cheers.

2. I code for a living mate, you can't make code too readable or other people can just come along and work out how the hell it works ;)

3. It was only sample code dude. The idea of making functions more general is to save effort later on, that's up to him.

Later,

ad 2. but people asking questions here NEED to know what is going on - otherwise they would not ask.
If you provide a working solution the person asking the question does not need to modify in any way, by all means. But a programming novice javascript or otherwise, would not have a clue as to what x() xA() xB() xC() siginified... (not that prakashk falls in the non-programmer category)

ad 3. No harm in teaching good technique from the start - saves questions later...
hence my comment number 1 to remind you (or tell you if you didn't know this)

It was a joke dude..

HAHA! Gnarly!

Thanks to LuxuryYacht and mplungjan to the comments. I hope to try it out today.

To mplungjan, even though I like perl, it does not mean i like short variable names. I like to make my code as readable as possible, as long as the elegance is not lost and the long names don't clutter up the code too much.

Good! - I was sort of joking, but when one sees some perl programs using sed and awk and regexp's they look like someone swearing ;-)
