Form Validation And Its Being Turned Off By End User?
Sep 4, 2011
I am a student and new to JavaScript, my problem is I am willing to do JavaScript form validation for emails , text etc.But on one of the forum I found out JS is not a very good way to do validation as JavaScript can be easily turned off by end-user and we shld always do server side validation also, but due to some concerns I want to stick to JavaScript (client side) validation.My scenario is somewhat like Ive a form and a button in it which on being clicked calls a JavaScript function that will validate the fields and then submit the form through form.submit();So my question is if JavaScript is turned off on end user then with validation the end user will also be not able to submit the form as the form is being submitted in a JavaScript function (which is turned off)? If this is thn cool.But is it somehow possible to hack this procedure, and one can skip the JavaScript validation but can still submit the form?

I am looking to add an email validation to my new user registration form. Currently, we do not validate (or activate) a new user via an activation link in the email. We don't have that process. I'd like to get my hands on the code to randonly create a security code and the actual code to sent the validation email. Can anyone help me out here? I'm absolutely new to PHP or ASP coding. I do know some HTML.

i have a form that has both front end and backend validation (php)
basically i got the code off the net, and it needs the submit button to be of type "button" rather than "submit"
and obviously the form doesn't submit if javascript is turned off
i'm not a javascript expert, on the button it has onClick="formvalidate())"
and in the javascript it has
if form is ok form.submit() or something to that effect
now is it possible to use a submit type so that if javascript is turned off, the form will still submit
but won't submit if javascript is on and the form is invalid
does it have something to do with the onSubmit attribute for the form
currently there is none
because we have the backend validation it doesn't really matter if javascript is turned off but it does matter if the form can't even be submitted at all

I'm creating an AJAX user validation so that when a user types in a username, it checks it in the database to see if it exists. I want it to execute after the user finishes typing. I've tried using:
$("#username_field").keyup(function(){
which works, but I don't want a query executed every time the users presses a key. I was wondering if there was a better way to do it. Meaning I what the check to be preformed after the user finishes typing.

I want to do a form validation and it should return a message like "should not be empty" when the user leaves the field blank..
I have html code like this
Now I want to know how can i display alert message to the user saying that the particular label name should not be empty..
For eg.. here I want to display alert as "Did you find this article useful? field should not be empty".... (Assuming this is mandatory)
I have so many fields like this in my form(checkbox, radio buttons, etc...) and i want to display alert with label name...
How can I do this using javascript.. (I know how to do validation in javascript popping up the alert(without label name), But I am not sure how to display alert with label name))))

I have a form with multiple fieldsets which are visible conditionally. There are three submit buttons "Abandon", "Save" and "Save & Continue". Each button should validate specific controls of the form and submit it. I tried setting "onsubmit: false" and checking for "$('#myForm').valid ()" on click of these buttons., but that validates all controls of the form.

I'm working on a program, it's a java servlet. It's interacting with an oracle DB. I need to add users and privaledges to the DB, but do not want people typing random usernames, I need to force them to use their company ID, i.e jmsmith, which is the username they log into their terminal from.
What I need to know, is there anyway possible to grab their current username from windows? i.e. a query to windows to see what user is currently logged into the terminal?

I'm using the Validation plugin for JQuery and was wondering if there was a function to submit the form without causing it to validate the form. I have a table with a list of radio-buttons and above that is a drop down list of states. The drop down list of states is used to filter the table rows and when the selected item changes it posts-back to the server (via $("#frm").submit()). I don't want this to cause any validation to occur. Is there another function I can call besides submit(), or some other method?

I have recently downloaded the jQuery Validation Plugin, and I want to use the bottom part of the demo [url] (Validating a Complete Form) and I have some questions to ask:
1. I want the validation to work after the user clicked "Submit"
2. If a column is wrong (username already taken or password length invalid) I want not only error message but also a picture in front of the error message.
3. I hope that after the user clicks "Submit" and then found a column is wrong then correct it, after the user corrected it and click to other place or other column the validator starts again to check the column the user just edited whether the user just corrected a wrong column or edited a correct column into error.
4. I hope to display a image in right of the column if that column is correct after the validator works.

In a registration form middleName field is optional. When the users enters his/her middleName, then it should validate that field. I have used the following code to achieve the above scenario, but it is not working.
$("#middleName").rules("add", {checkName: true, required: false, messages: {checkName: "Please enter a valid middle name"} });
jQuery.validator.addMethod("checkName",
function(value, element) {
var regExp = new RegExp(/^[a-zA-Z0-9s|,|.|-|']+$/);
return regExp.test(value);
},
"Please enter a valid name."
);
How to achieve the above scenario.

I have my website www.gebcn.com. If you view source you will see all that I have done, but more importantly my problem. I have the JS code at the top there and I am unable to W3C validate my HTML because of the JS. I am using XHTML strict and would like to stay using it.
The JS I have at the top is my form validation code. I am able to do any validating that I need with this "snippet" of code, I have shrank it from my library version just to use for this newsletter. Until now W3C validating was not important now for some reason it is and I am faced with this problem.
I am not a Javascript guy more of a HTML/CSS guy and I can manipulate JS to suit my needs.
<problem> I have tried to make this "snippet" of JS code an external file but receive multiple errors with the JS calling for the FORM NAME as it is not on the same page. The form NAME=NEWSLETTER is another problem, as W3C says I am unable to use attribute "NAME" in this location. <problem> I would like to keep the JS close to how it is now as I have a library to use this JS over and over again.

I've found a neat little single drop down for a link list. It works fine, but if I turn JS off in my browser the links will not show. I do have a 100 liner that will show links when JS is off, but I'd rather adapt this to do it.
How do you make it so that the list will show regardless of whether JS is on of off. I want the drop if on, which is why I use it.
Code:
<html>
<head>
<title>Drop div</title>
<style type="text/css">
<!--
#ardd{width:180px;}

I have a modest website that uses a lot of Javascript.
If anybody views the site and does not have Javascript enabled I want to
politely redirect them to another page, so I put this bit of code in my
<head> section :
<script type="text/javascript"
language="JavaScript">document.write("<!"+"--")</script>
<meta http-equiv="Refresh" content="0; URL=noscript.html">
<!--//-->
So far so good.
It appears to work, *and* it passes the the 'W3C MarkUp Validation Service'
test ( http://validator.w3.org/ ).
Now the bad news: Google doesn't index my site any more, presumably because
their crawler always gets redirected.
Does anybody have a solution to this dilema, please?
Redirecting to a 'with-script' page is not an option because my page is
linked-to by many other sites.

I am trying to make an order form I am working on accessible for users who have javascript turned off in their browser, and to do this I would like to hide a div if JS is disabled.
Searching the Web has led me to think that styling the div to not display is the way forward and then using JS to display it. It is the JS bit I am struggling with! The div in question is a set of radio buttons to allow a purchaser to choose how many gift memberships they want to buy:
<div id="giftmember-buttons" style="display:none";>
<h2 class="threepeaksform">How many gift memberships do you wish to purchase?</h2>
<fieldset class="threepeaksform">
<legend>Please select the number of people you are buying a gift membership for using the buttons below.</legend>
<div class="generalcontactform-group">

My page has a form which has some sections that do not show unless needed, but if JS is turned off then these section will never show, so looking for a way to test if it is on or not and if not allow the page to display everything that would normally be hidden unless needed.

Can anyone point me to statistics on how many people don't have javascript .. or have javascript turned off? I'm about to purchase a template to re-design a site. I know javascript can do some neat things, but I'd like to keep the site accessible to as many as possible .. and easy to maintain (it's a volunteer organization, which may pass the Web design responsibility around from time-to-time).

Does any one know of a way to redirect someone with JavaScript disables to another page (or would we need a little JS to accomplish this?)
I'm putting together a site that uses a horizontal javascript drop down navbar, and thought it would be coolness to redirect those that either cannot read js, or have js turned off to my site map page.
