Hi Everyone!
In my project I'm validating the value of a textbox using the javascript code below. This code is working on IE, but not any other browser. Can anybody on help me with this issue.

This is from the code behind file:

C#

protected void Page_Load(object sender, EventArgs e)
{
    txtInvNopr.Attributes.Add("onblur", "return validate(this.value)");
}

This is my javascript code:

JavaScript

function validate(content)
{
    if(isNaN(content)==true)
    {
        alert('Enter Only Numeric Value');
        return false;
    }
    else
        return true;
}

Thanks in advance!

Edit: Spelling, grammar and clarity. Added code blocks, tidied up indentation.

This example works by only using javascript. It runs absolutely perfect on IE 8/9, FireFox 6.0.2 and Chrome 12.xxxx.

HTML

<html>
<head>
<script type="text/javascript">
    function validate(content)
    {
        if(isNaN(content)==true)
        {
            alert('Enter Only Numeric Value');
            return false;
        }
        else
            return true;
    }
</script>
</head>
<body>
<h1>Get attribute test!</h1>
<input id="btnClientId" type="text" value="" name="Whatchamacallit" onblur="return validate(this.value);"/>
<input id="submitIt" type="button" value="Do it!"/>
</body>
</html>

It must be something else that is going wrong in your code. Please use FireBug to debug your pages javascript.

If you are still having trouble, you can so long use parseInt() which i know will work in all browsers (i.e. IE5):

JavaScript

function validate(content)
{
   if(!parseInt(content))
   {
      alert('Enter Only Numeric Value');
      return false;
   }
   else
      return true;
}

Goodluck,
