Auto calculate and add $ sign in javascript
Hi,
I have a form where I have six text box one each for the money spent on travel, food, other expenses and a total for these three fields. Another set is for education, advertisement and a total for these two fields. My data taype is float and I want to display a $ sign when the user enters in any text box.
The total for the first set travel, food and other expenses should be calculated automatically whenever the values in any of the text box change. The toal for the second set should also be calculated Then I have GRand total field which is sum of the total of both sets and should be calculated and displayed with $ sign

It will be better if you post your form OR provide a link so we see the form.
And if it is homework, please do some of it yourself

1. I would use onKeyUp and pass the form:
onKeyUp="calc(this.form)"
then in calc I would calculate ALL values
I wrote a script for you, but my editor crashed. I will see if I can get a temp file back
onKeyUp="calc(this.form)"

Thanks but my problem is that i need to display $ sign in each text box when the value is entered and also in both total field and grand total and whwever th euser changes the value in any input textbox the total field and grand total should reflect the changes with $ sign in front. I had tried this function to add dollar sign but for som reason when I use this function it only displays the dollar field in totals of each section but Grand total shows Nan and individal text box does not show $ sign.
<!-- Begin
function formatCurrency(num) {
num = num.toString().replace(/\$

num = "0";
sign = (num == (num = Math.abs(num)));
num = Math.floor(num*100+0.50000
cents = num%100;
num = Math.floor(num/100).toStri
if(cents<10)
cents = "0" + cents;
for (var i = 0; i < Math.floor((num.length-(1+
num = num.substring(0,num.length
num.substring(num.length-(
return (((sign)?'':'-') + '$' + num + '.' + cents);

Hi I tried to use this function in may asp.net page but I get error object expected. Is it possible to call this function on keyup event or keydown
myMasterpage.SetBodyOnLoad
Public Sub SetBodyOnLoadScript(ByVal strOnLoad As String)
body.Attributes.Add("onloa
End Sub
myMasterpage.SetBodyOnLoad
Public Sub SetBodyOnLoadScript(ByVal strOnLoad As String)
body.Attributes.Add("onloa
End Sub
>>I tried to use this function
What function?
Your post makes no sense. I am not familiar with your environment. What I gave you works as you desired. I tested it as a stand alone page. You just need to make your server generate the HTML code I gave you (minus the commented out server code of course. I left those there just so you know which server fields correspond with which <input type="text"> tags).

Thanks it works absolutely fine but I am calling it on onblur. It didn't work on onload event for some reason.
