Hi Alwin,

1. If you are using struts framework, you can specify what that text field should hold to be valid. It should be specified in validation.xml file. You can specify regular expression as that fits your requirements.

2. If you want only client side validation, then you can validate the value of that text field with the help of javascript. It has function isNaN().

Hope this helps.

Thanks

Use this

onblur=mask(this.form.acno) //acno is field name

function mask(val)
{
  if(isNaN(val.value))
  {
    alert("Not a number");
    val.focus();
    val.select();
  }
}
