Write a generic validator that takes any input field and validates it according to your requirements. You then call that finction on each of your text boxes.

what do you mean by generic validator?please pardon me because im not that proficient in javascript...
But I have a script here to get the values of Html textfields:
<script language="JavaScript">
function function1() {
var m = document.getElementsByName("myE");
alert(m[0].name + "/" + m[0].value);
alert(m[1].name + "/" + m[1].value);

<form name="form1">
<input type="text" name="mytxt1" id="myE" value="">
<input type="text" name="mytxt2" id="myE" value="">
<input type="button"
value="Get the number of elements that have the same name"
it works fine on IE browsers..but not on firefox...
when you browse it on IE it detects 2 textfields, but on Firefox it only detects nothing...can you please explain me this problem?

Hi Dude, I hope this code will help you. But you have to enhance yourself to your need.

<script language="javascript">
var choice;
function createText()
choice=parseInt(document.getElementById('user').va lue);
var textId;
for(var i=1;i<=choice;i++)
textId = "textId"+i;
var udiv=document.getElementById('myDiv')
var newEl=document.createElement('input');
newEl.type='text'; = textId;

function validateText()
var textId
for(var i=1;i<=choice;i++)
textId = "textId"+i;
var temp = document.getElementById(textId).value;
alert('text '+i+' is null');
<div id='myDiv'>
<input type="text" id='user'>
<input type="Button" value="generate" onclick="createText()"><br/>
<input type="button" value="validate" onclick="validateText()">

Pls Post back your feedback. If you need more help i can help you out
