Set the maximum value for text box.

[getmeidea]

Code:

<script language="javascript">
    function setMaximumValue(txtObj, maxVal){
        var tempVal = parseFloat('' + txtObj.value)
        window.event.returnValue = (tempVal <= maxValue);
    }
</script>
<form name="frmSample>
    <input type="text" id="txtAmount" name="txtAmount" value="" 
        onkeypress="setMaximumValue(this, 100.00)">
</form>

Description:
Assume i will enter only numeric to text mox.
Here i want to set maximum value for the control txtAmount.
The maximum value can be numeric, decimal.

But here the keypress event is triggered, then typed character getting updated to "txtAmount" .

So what is the wright way to make this functionality.

Use Code Tags.
It's not working :-)

Check this code, it is working fine..

<script type="text/javascript">
    function setMaximumValue(id,maxVal){
        var txtObj=document.getElementById(id).value;
        var tempVal = parseInt(txtObj);
        if(tempVal>maxVal)
        {
            alert("Value cannot be taken");
            document.getElementById(id).select();
            document.getElementById(id).focus();
        }
//        window.event.returnValue = (tempVal <= maxVal);
    }
</script>
<form name="frmSample">
    <input type="text" id="txtAmount" name="txtAmount" value="" onkeyup="setMaximumValue(this.id,100.00)">
</form>
