Entering decimal numbers only in javascript
Hello!!
Do you know of any solutions to this following problem: preventing the user from inputting whole numbers (integers) and allowing the user to enter the decimal numbers instead? Thanks!!!

RE: Entering decimal numbers only in javascript
I came up with this, which seems to work.
Code:
<script language="javascript">
<!--
function isFloat(num){
if(isNaN(num) || num.indexOf(".")<0){
alert(num+" is NOT OK!");
}else{
num=parseFloat(num);
alert (num+" is OK!")
}
}
//-->
