How to add the two value and then display it in a Total field 1

yogi564 · Jan 7, 2002

hi all

Can somebody help me out. I need a code that will add two fields and then give me a total value in third and final field. It should allow users to input their own numbers as well as decimal point in the two fields to give the final value. thank's

hi

i put this example for you and it should work on both browsers.

note:
if you dont use the parseFloat method then you add the 2 elements as a string....

<HTML>
<HEAD>
<TITLE></TITLE>
<script language="javascript">
function add()
{
//here is one way of doing it: document.forms["myForm"].num1.value
var n1 = parseFloat(document.forms["myForm"].num1.value);
var n2 = parseFloat(document.forms["myForm"].num2.value);

//here is another way of doing it:document.forms[0].
document.forms[0].sum.value = n1 + n2;
}
</script>
</HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000" LINK="#0000FF" VLINK="#800080">
<form name="myForm" action="javascript:add()">
<input type="text" name="num1" value="num1"><br>
<input type="text" name="num2" value="num2"><br>
<input type="submit" ><br>
<input type="text" name="sum" value="sum">
</form>

</BODY>
</HTML>

Hi raikyng

I s there a way of not using a submit button, but when you just enter the two specific field it should automatically give the sum value without pressing the submit button.

Thank's
