Javascript help
So I am doing a simple menu ordering for a javascript class but the only problem I have is that I need to add up three text fields which when you on click on a item it will have the cost (in one of the text fields) which contain decimals in them. I tryed parseFloat() and parseInt() but it doesn't work with decimals.
__________________Is their a way to add numbers that have decimals in them?

You just have to convert them to decimals (doubles) right away.
Here is a full example Code:
<head>
<title>JS Example</title>
<script type="text/javascript">
function addThese(t1, t2, t3)
{
var v1 = parseFloat(document.getElementById(t1).value);
var v2 = parseFloat(document.getElementById(t2).value);
var v3 = parseFloat(document.getElementById(t3).value);
var total = v1+v2+v3;
document.getElementById('output').innerHTML = total;
}
</script>
</head>
<body>
<input id="Text1" type="text" /><br />
<input id="Text2" type="text" /><br />
<input id="Text3" type="text" /><br />
<input id="Button1" type="button" onclick="addThese('Text1','Text2','Text3')" value="button" />
<div id="output"></div>
</body>
</html>
