Use the Regular expression with a java script like below.

Java

function validate()
{
 var ex = /^[0-9]{5}$/;
 if(ex.test(document.getElementById('textBoxId').value) == false)
 {
    // alert code goes here
 }
}

Call this function on onblur evenr of the text box.

Java

<input type="text" id="textBoxId"  onblur="validate();" />

// ViaJavascript-------------------------------------

function CheckLength(events, args)

 var x = (document.getElementById(txtTestForLength).value);

    if(X.length>5)
    {
        args.IsValid = false;
    }
    else

             if(isNaN( x)
                {
