Form - Multiple buttons - Which one pressed?

activethistle · Feb 12, 2002

I have a form with about 150 buttons on it. How do I determine which one has been pressed? They all have names like b1, b2, b3 etc...
I guess document.forms(0).elements comes into it somewhere?

Try this:

<form name="update">

<INPUT TYPE="button1" NAME="perform" ONCLICK='document.update.whichbutton.value=1;document.update.submit()' value="Button1">
<INPUT TYPE="button2" NAME="perform" ONCLICK='document.update.whichbutton.value=2;document.update.submit()' value="Button2">

<input type=Hidden name="whichbutton" value="">

</form>

Then all have to repeat the number of buttons to 150. And then on the next page just reference the value for
whichbutton and you will get the corresponding value.

Hi,

I think this is a bit shorter:

<html>
<head>
<title>150buttons</title>
<script>
function dataval(no) {
document.form1.whichbut.value=no;
document.form1.submit();
}
</script>
</head>

<body bgcolor="#FFFFFF" text="#000000">
<form name="form1" method="post" action="">
<br>
<input type="hidden" name="whichbut">
<br>
<input type="button" name="Button" value="0" onclick="dataval(0);">
<input type="button" name="Submit2" value="1" onclick="dataval(1);">
<input type="button" name="Submit3" value="2" onclick="dataval(2);">
<input type="button" name="Submit4" value="3" onclick="dataval(3);">
<input type="button" name="Submit5" value="4" onclick="dataval(4);">
<br>
<input type="button" name="Submit6" value="5" onclick="dataval(5);">
<input type="button" name="Submit7" value="6" onclick="dataval(6);">
<input type="button" name="Submit8" value="7" onclick="dataval(7);">
<input type="button" name="Submit9" value="8" onclick="dataval(8);">
<input type="button" name="Submit10" value="9" onclick="dataval(9);">
</form></body></html>

Continue the <input> tag until 150 buttons with the same format and in your receiving code evaluate variable whichbut to determine which button is being clicked.
