I am building a site that need to compute $10.00 for each item checked in a check box.
All items are $10.00.


Thanks,

Hi!

For example:


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Untitled</title>
<script language="JavaScript" type="text/javascript">
<!--
function addToTotal()
{
document.forms[0].Total.value = 0;
for (var i=0; i<document.forms[0].elements.length; i++) {
textObj = document.forms[0].elements[i];
if (textObj.type == "checkbox" && textObj.checked) {
document.forms[0].Total.value = parseInt(document.forms[0].Total.value) + parseInt(textObj.value);
}
}
document.forms[0].Total.value = "US$ "+ document.forms[0].Total.value;
}
//-->
</script>
</head>
<body>
<form>
article 1: <input type="checkbox" onclick="addToTotal()" value=15> US$ 15,-<br>
article 2: <input type="checkbox" onclick="addToTotal()" value=10> US$ 10,-<br>
article 3: <input type="checkbox" onclick="addToTotal()" value=10> US$ 10-<br>
article 4: <input type="checkbox" onclick="addToTotal()" value=10> US$ 10,-<br>
article 5: <input type="checkbox" onclick="addToTotal()" value=25> US$ 25,-<br>
total amount: <input type="text" name="Total" size=10><br>
</form>
</body>
</html>

BTW - I deliberately did not leave each single value at 10$$ - so you'll be a bit more flexible...

Cheers - Pit

Hello and
Thank you so much, this one will work for what i need.

If you have a website I could give a link or credit to you for the script.
thanks again.

Hi!

You're welcome!

I don't have a website and besides that (hoping I can talk for others here too) positive feedback for some small help is enough!

I just put "pittimann's" script up in 30 seconds.
Now my site is complete!

Thanks a bunch...

Hi again!

One thing I didn't mention: if you add more forms to your document, the script will only work, if the form with the checkboxes stuff is the first form (form[0]=first form, form[1]=second form etc.). If you put one form before this one, please change "forms[0]" to "forms[1]" etc.

Inside the form, the script is dealing with, you can add another checkboxes, like:

article 6: <input type="checkbox" onclick="addToTotal()" value=100000> US$ 100000,-<br>

without altering the script...
