Form Submission Validate One Field Against Another?

Sep 28, 2011

I wonder if anyone can assist me here. I am trying to find the best way to validate a field against another field. In this case I need to make sure when the user enters the date of birth that the date is not prior to another date in the database (admission date). I would like to do the validation on submit before the other data from the field is submitted to the database.

I have seen a lot of forms validation that can compare the inputted value to a range of values, but I need to say "is the birth date prior to the admission date? If NO then give a message to the user to recheck the date". Sounds easy, but I haven't found a clean way to do it.

JQuery :: Prevent A Particular Field Being Submitted In Form Submission - Ajax Submission Doen't Work

Jun 1, 2009

I have email, password and some other fields, and I'm using $.post to send data for Ajax submission.

The problem is that I don't want to submit a particular field. The serializeArray() returns all the fields in the form. So, I tried something like this to prevent the password field being serialized.

This works great but the ajax submission doen't work.

Using Validate And Act On Form Submission In CSS Box?

Jun 14, 2010

I'm working on a project for my company that will be deployed next week. In a nutshell, we have a bunch of touchscreen computers that we are using as kiosks for an internal event. The various screens have been build in XHTML/CSS, with a smidge of javascript for the few points of interactivity that aren't being handled through the HTML.

I just started dabbling in Javascript for this project about a month ago, and I think with enough time, I could probably figure this out. But I'm feeling crunched on time, and I thought someone here might have a simple solution.

So here's where I am. The "boss" doesn't want to use the built in browser alert/prompt boxes, which is fine by me, since I can just skin up some alerts in CSS, and attach JS functionality to them. But I ran into a snag in one of them. On each kiosk, we are placing a transparent DIV in the upper corner that invokes a password prompt. If the password matches the password stored in the JS, the kiosk browser window closes (window.close). If the password doesn't match, the user is informed of such, and remains in "kiosk" mode.

For the password box, I've written in a hidden box in CSS, who's display value is set to visible when someone hits the hidden area in the upper corner. That works fine. The box itself is a <p> that simply prompts the user to enter the password to continue. I have a form with a text field as well as an "ok" button.

Here's where things stop working. If I pre-define the value of "var password" to be the correct password, clicking the OK button works as expected. But if I try to use the user input from the form, I get an error. I'm happy for someone to start me from scratch if the below code isn't workable. Here's what I need:Password prompt box that's skinnable in CSS.Value checked against stored variableIf accepted, window closes.If denied, user is informed and prompt box is returned to hidden state.

[Code]...

One note, before I toss this to you all. If it's easier/better to simply include the error message as part of the FORM, instead of it's own separate box, I'm A-OK with that.

Read And Write A Field Variable / Value Before Form Submission?

Aug 24, 2010

I was wondering if there was a way to dynamically read a field input and respond to it later in the form. My situation is this: I have a question that asks how many workers are employed at a business. Later in the form, the user is asked to add as many workers as they have (section with information on each worker) ..Is there a way I can have something echoed or document.write above the latter section saying "Please add (Number of workers listed above) sections for each worker employed"

JQuery :: Input Field Bypassing By <enter> Without Form Submission

Feb 9, 2010

I want to bypass from one input field to other one by <enter> (<return>) key pressing instead of default behaviour (<tab> key pressing).But there was default form action on <enter> keydown event was performed. Remember that <enter> keydown event on form means default "Form submit" action. How to prevent default action, form submission, in time of <enter> keydown event processing?

How to modify following code? I use hotkeys jQuery plugin for key binding to input fields.

$().ready(function(){
$(myInputFieldsSelector).bind('keydown','return',function(evt){
//find next input field in the form MyNextInput
MyNextInput.focus().select();

Validate Form On Just Few Variables In One Field

Jan 27, 2010

I have a JS which validates the correct format for postcodes (or zip) on an html form - works fine.But what I want to do is to use a JS to see if a website visitor is eligible for a particular service on their postcode / zip - ie the first general part on the code. For example if they type L15****, or L16**** or L18 (where the asterisk could be anything) it pops up the alert box with a message saying "Yes eligible" but any other code returns "No sorry not eligible" - eg L19**** it returns nope.I've tried hacking the code that validates to format and can manage it for just the first character - ie the L but I'm totally lost after that. I don't know if hacking the below will work.

Validate Individual Text Field Validation On Form?

Jan 14, 2011

I have written a form in HTML which contains username,lastname,email,password and submit.I have written a javascript to validate this form [validate(username,lastname,,password)].On submit this javascript function will be called and hence form get validated. I am passing all the arguements(username,lastname,email and password) to the javascript function..Is it possible to make me a code such that it should call an individual function for each field in the form.for ex:if i have not entered username, last name in the form and attempt to submit, only username arguement should be passed to the function as it comes first in the form.In other sense i want to validate individual text field validation of my form.

Validate A Web Form - Sending Email Alerts With Every Field Blank

Jul 13, 2011

I am trying to validate a web form. Someone else wrote the Html code and implemented it with an iframe using asp and php. I didn't want to mess too much with the code so I decided to use javascript to make the form validate, before it was sending email alerts with every field blank. For the most part the validation works but it skips the email field for some reasons and is really bugging me to death. this is the code:

<head>
<link type="text/css" rel="stylesheet" href="CSS/style.css"/>
<title>Bid Form</title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<script src="gen_validatorv4.js" type="text/javascript"></script>
<script type="text/javascript">

JQuery :: (Validate) Individual Form Field Failure And Success Events?

Aug 31, 2009

I'm trying to figure out how to integrate jQuery Validation plugin with the qTip plugin [0] to show custom error message displays. I've
had partial success with the following code:

$("#RegistrationForm").validate(
{
errorElement: "span",[code]....

At this point, that successfully displays the validation failure message in a qTip tooltip when it occurs, but there are two problems
with it:

1) The error tooltip toggles between visible and invisible onmouseover and onmouseout. I'm sure this isn't really an issue with the Validation plugin, but rather something I need to figure out with the tooltip plugin. But, my bigger problem is...

2) Even when the invalid condition is fixed (valid data is later entered into the field), the error tooltip remains attached to the field that was previously invalid, even after the field is valid, and continues to toggle between visible and invisible onmouseover and
onmouseout. I'm fairly certain that this is because I've not yet destroyed the tooltip object, but, I can't seem to figure out a way to intercept the "valid" or "success" event with a reference to the element so that I *can* destroy the attached tooltip object.any experience with combining qTip with Validation, or, if I'm missing something in the docs (I've not been able to find anything like this yet) about how to handle/override event handlers for individual form element invalidation/success. I *did* try attaching a function to the "success" attribute of the validate function, but that seems to only give me a reference to the success label, and not the element that its attached to.

How To Read Value Of Non Text Field After Submission?

Jul 7, 2006

I have a form that, during submission to another page, uses the submitted text field data and creates a cookie. But how would I do that with a radio button/checkbox field or pulldown? Just fyi, the code is created using onsubmit() and processes this before the response page.

All demos I see are for self submitting (same page) scripts. Not for those going from form.php to response.php and I cannot use this type of submission and find a value for a NON text field. I need to recognize non text fields since I want to create cookies for all form fields, not just text fields.

The code I have, to read the value of a text field is here:
var email = document.myform.email.value.split(' ')[0];

I just want to have something similar to above, using 'myform' as the form name, but able to get the value for any *non text field*

is this possible? The rest of the code I won't post as it isn't relevant. I just need to read a value of a non text field and I can work with that.

JQuery :: Validate Is Failing On A Field That Is Not A Required Field?

Nov 19, 2010

I have a credit card field that is only mandatory if they select a credit card as a payment type.

If they select Gift Certificate, then I set the card to not be mandatory:

$('#creditcard').removeClass('required').removeClass('creditcard');
validationRules.rules.CardNumber.required = false;

however the validation still fails on the creditcard field. If I enter this in to Firefox's console:

$("#OForm").validate().element("#creditcard");

it returns false.

To make matters more confusing, this validation only fails on my form when I am passing a particular parameter in the URL string. I've scoured my code and cannot figure out why that parameter would have any impact whatsoever on this matter.

JQuery :: Malsup Form Plugin And The JSON Returned From A Form Submission: The Error Callback Is Always Called?

Aug 19, 2010

I'm having troubles with an existing J2EE application (which uses Dojo) and in which I'm gradually introducing jQuery. The specific issue is with the malsup Form plugin and the JSON returned from a form submission: the error callback is always called, regardless of what happens on the server side, and the error is always "parsererror". I'm using jQuery 1.4.2 and the 2.45 version of the malsup Form plugin.
For example, given the following code:

$(document).ready(function() {
var options = {
dataType: 'json',[code]....

the server receives the submission and handles it without errors, then in the browser I always get the same alert from the processAddressEditSubmitError() function, with an "Invalid JSON" message:

pStatus=parsererror
pErrorText=Invalid JSON: {"nickname":"trytrez","success":"success"}

However, the JSON looks OK for me (and http:[url]...agrees that it is valid).

Pop-up Form Submission

Aug 14, 2001

I'm having a few problems... none are caused by my browser, so they are proving hard to troubleshoot. A user has pointed a couple out to me.

I have this code as part of a script:

(I have inserted hard breaks to make the post look better)
----------------------------------
window.open("http://www.site.com/loading.htm","confirmation","screenX=10,screenY
=10,left=0,top=10,toolbar=0,location=0,status=0,menubar=0,scrollbars
=1,resizable=0,width=250,height=250");

document.subForm.submit();
----------------------------------

"subForm" targets "confirmation". The user is getting two windows instead of one. One contains the initial window document and the other contains the form action. Also, she says they are both big... the size (of at least one) should be 250x250. She is running AOL 6 and IE 5.5 on the related computer.

Perhaps a timeout would help the 2 window situation? Why are the windows big and not 250x250? If you know what's going on please let me in on it.

This same user has a laptop that runs AOL 4 and IE 4 (she thinks). On that computer the form is submitting to one window, but none of the data is making it to the new window. I am guessing this has to do with the way I have the "form" and "table" tags within the javascript document.write statements. Does anyone know a good web page on this subject? OR What else the problem might be?

Ok, next issue! I am trying to submit a form using Netscape 4.03. When the submit button calls the related function I receive: "subForm is not defined". Here is the line that is throwing the error:

----------------------------------
eml = subForm.email.value;
----------------------------------

The final problem is regarding the same form. When I hit the submit button in N6... nothing happens.

Faking A Form Submission

Jul 23, 2005

Is there a good way to use JavaScript to send a form submission, but get
back the response as a string, rather than loading it into a page? I
could write the code to send the submission via XMLHttpRequest, but that
seems hard... especially implementing multipart-encoded form submission
such as required for file upload.

Cannot Break Form Submission?

Jan 13, 2010

I'm using simple form validation, found online, to check certain fields before submitting. The problem is that, although the script detects the error/missing field/wrong syntax and pops up the corresponding alert, after the user presses OK in the alert box the script continues and sends the form - which of course is not valid.

HTML PART:

<input name="Submit" type="submit" class="textfield" value="Register" onclick="checkitems();">

JAVASCRIPT PART:

function checkitems() {
valid = true;
if ( document.registration.Onoma.value == "" ) {

Form Submission With Iframe?

Jul 23, 2009

user fills in a form (selects files for upload, writes a post, etc.) and submits it - without page reload she gets a response from server (error, unsupported file type, inappropriate language, success, etc.)I imagine first, submit-without-reload, part is done via the form.target property like this: - iframe is either created dynamically with JS createElement or statically. But in any case it should look something like this:

<iframe id="#iframe123456" name="#iframe123456"></iframe>

- form, also created either dynamically or statically:

<form action="process.php" target="#iframe123456">
<!-- inputs of various types -->
</from>

As for the response/result part, server dumps its reply into the targeted iframe, so I have three alternatives:- use iframe's onLoad (onReadyStateChange) event: attach a get_data() function to it.- frequently/manually poll iframe for data using setInterval(get_data, milliseconds). - inject some script into the server response that makes iframe itself call get_data() .how I can check if an iframe has data in it.I use the following script to get the iframe's inner document object (excerpt from get_data() fucntion ):

if ( iframe.contentDocument ){
doc = iframe.contentDocument;
}else if( iframe.contentWindow ){

Using Post In A Form Submission

Nov 3, 2011

I am trying to validate a form field using a $.post request and am having an issue with timing because of the synchronous property of the post I assume. If I put in an alert, it works fine because the post has returned in time to stop the form submission. Here is the original way I did it but the form is submitting before I can send the return = false.

Code JavaScript:
$('form#form-oidupdate').submit(function(e) {
var srchstr = $('form#form-oidupdate input').val();
var passdata = {'type': 'availability', 'srchstr': srchstr};

Form Submission If Js Turned Off

Mar 10, 2005

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
