To stop server eventing in case of javascript error

Question

Hi,
I have another simple query:
I have written few javascript validations like:
var data = this.value;
if ( isAlpha(data) != true )
a_lert("Name should not contain numbers");
document.getElementById("firstname").style.color = "red";
document.getElementById("firstname").style.borderColor = "red";
It is working absolutely fine and the alert is appearing. Now my requirement is to stop any server side event to occur like oninputprocessing if the javascript error persists.
Please guide.
