submit on enter ?

**Golgotha** · Sep 3, 2003, 11:49

in a typical form when you hit the enter key it will submit the data, however I am not using a submit button but rather a regular button the calls this funtion:

Code:

 
function submitDB(){
var itemnum = document.formhandheld.itemnum.value;
var readSource = 0;
var readType = 0; 
window.location.href = "PocketPCDetails.asp?ScanCheck=1&itemnum=" + itemnum + "&readSource=" + readSource + "&readType=" + readType;  
}

I would still like the enter key to submit or call this function. HELP!

add an onSubmit(submitDB); to the button?

**bbolte** · Sep 3, 2003, 12:37

actually, it's this (i think) in the action portion of the form:

onSubmit="submitDB();"

Did this work? I'm really interested in this.

**Golgotha** · Sep 3, 2003, 12:56

hmmm, not sure I get that, like action="submitDB()" ??

and then do I change the button to be a submit button

I cant seem to get it

**bbolte** · Sep 3, 2003, 13:31

can we see the relevant code?

**Golgotha** · Sep 3, 2003, 13:36

here's what I have:

Code:

function submitDB(){
var itemnum = document.formhandheld.itemnum.value;
var readSource = 0;
var readType = 0; 
window.location.href = "PocketPCDetails.asp?ScanCheck=1&itemnum=" + itemnum + "&readSource=" + readSource + "&readType=" + readType; 
}

Code:

 
<form method="get" name="formhandheld">

Code:

 
<input type="button" name="Details" value="&nbsp;Details&nbsp;" onClick="submitDB()">

FYI, the code works, but I cant use the ENTER key, need that

**bbolte** · Sep 3, 2003, 14:00

the enter key probably has to do with it not being a submit button(?). hmmmmm... any reason why it can't be a submit button?

I figured this exact problem out in my previous job on a project. I can't remember what code I used, but I remember that I had to get the Javascript to recognise that the return hit had been pressed, which is number 13 on the keycode list (if I remember correctly).

These links might help somewhat:

I GOT IT...
strange though had to remove the form tag.

**bbolte** · Sep 3, 2003, 16:59

woo hoo!

Actually, removing the form-tag is not the correct way, as this introduces an incompatibility. Some browsers will even choke on a submit button that is not found within a form.

The correct way to handle this is to place an onsubmit event handler in the form tag:

Code:

<form ... onsubmit="return submitHandler()">

ok, perhaps then you can help me, since as soon as I add the form back it wont work....

relevent code is in red...

Code:

function enterkey(eEvent) {
  if (eEvent.keyCode == 13){
	submitDB();
 }
 return true;
}
function submitDB(){
var itemnum = document.all.itemnumHolder.value;
var readSource = 0;
var readType = 0; 
window.location.href = "PocketPCDetails.asp?ScanCheck=1&itemnum=" + itemnum + "&readSource=" + readSource + "&readType=" + readType;
