Hi,

I want to have a textbox in which only numeric values will be allowed whose maximum limit is 240( 230.99 should be allowed). I am unable to do that. I am able to format the value entered by placing . in proper places and also I have limited upto two decimal places. But the problem is the cursor is not moving left when I have entered a value and I am unable to limit the value upto 240. It is taking any huge number also. Please help. My code is as below :-

<html>

<head>

<script>
function isNumberKey(evt)

{

var charCode = (evt.which) ? evt.which : event.keyCode

if (charCode != 46 && charCode > 31 && (charCode < 48 || charCode > 57))

return false;



return true;

}



function format(input){

var num = input.value.replace(/\,/g,'');

if(!isNaN(num)){

if(num.indexOf('.') > -1){

num = num.split('.');

if(num[1].length > 2){

num[1] = num[1].substring(0,num[1].length-1);

} input.value = num[0]+'.'+num[1];

} else {

input.value = num.toString().split('').reverse().join('').replace(/(?=\d*\.?)(\d{3})/g,'$1,').split('').reverse().join('').replace(/^[\,]/,'') };

} else {

input.value = "";

}

}
</script>
</head>



<body>
<label for="time">Files staged in the last -</label>

<input name="time" id="time" type = "text" value="24" onkeypress="return isNumberKey(event)" onkeyup="format(this);"/> <span>hours</span>
</body>
