Best Form Validation Display Technique
Oct 9, 2009
I'm looking for different JS form validation techniques. I've seen quite a few but nothing that really stands out. I'm particularly interested in finding design techniques...ie: how and where are the errors displayed inside a form? I realize that I can't count on JS for validation, but I'm trying to add an assistive technology to make a web form feel more like a web application. I'd love to see your favorite way of displaying form errors via JS. I've got a few of my own but if you've ever tried to do this you know it's a difficult problem to handle the general case.

I am trying to display validation error messages when form validation fails. Currently it does display the error messages but then disappears straight away. How can I stop the page from refreshing when validation fails? I have return false in my code when validation fails but still having same problem. Currently I have only done the validation for the full name only. The error msg is showed in:

A website I'm designing vgdesign.net/thc has a form in the footer. It functions how I want right now (to my knowledge) except for the fact that after a user submits a form and it passes validation, I want a message to be displayed that says "Thank You". I have a class created for this in my stylesheet but I don't know how to trigger it when the form is sent successfully. Essentially, I would like the result to look like this:
If the form doesn't pass validation, I want it to not display until the users fix the errors in the validation pop ups and resubmit. The php script that sends the form contents to the specified email is at the top of my index.php page. The validation tool I'm using is called jquery inline form validations (found here: [URL] How can I have that success message pop up when the form was successfully submitted?

We all know that feature detection technique works from very beggining
of user-agents supporting JavaScript. We can alway check if eg.
document has a write property or smth else:
if(document.write) {
}
We could do that for all of objects, so i have been surprised when i
found 'in' operator, which for above example would be used like this:
if("write" in document) {
}
So i have questioned myself what for ? I can always do:
if(document["write"]) {
}
or even
var prop = [...];
if(document[prop]) {
}
which is supported better then 'in' operator ('in' is supported since
W. IE 5.5 and NN 6 - around 2000 year). I can only guess that 'in' was
provided in W. IE 5.5 only for convenience... but that is my guess and
someone more knowlegable could write here some more opinions on this
operator...

I'm planning on making a website which is mainly just a gallery of images.
The site will essentially look like one page with a jCarousel on it, when the user clicks left or right on the carousel, I would like the URL to change but for the animation not to get interupted.
I would also need to change some HTML on the page too, essentially each image will have a Facebook 'like' button and that will need to change to the corresponding URL.
The carousel is going to be database driven and dynamically built up with potentially 1000's of images, so I'm not sure what the best technique for this would be? I'm building it in ASP.NET / Ajax and using the SlideJS carousel [code]...

This is what I'm attempting at the moment, links is an array. Should this work? I understand that HTML headers cannot contain complex datasets like arrays, so what format is the data sent in? Ie. how do I decompose the array on the PHP end? Or is there a better way entirely of doing this?
$.ajax({
type: "POST",
url: "http://asdfasdf.heliohost.org/multiurl.php",

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 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 need to validate two forms containing multiple input fields but want just one error message if any of the fields are left blank, the page is required to submit the users details (registration form). Also if any of these fields are left blank i don't want to be able to go to the next page on clicking the submit button

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 have a validation script for upc codes which is currently working for
values that are entered into one text box. I've been asked to break up
the text box into 3 separate fields to accept the 1st digit, middle 10
digits, then last check digit. What I'm doing is substringing the
initial values then concatenating them. What I'm not sure of is, how to
handle the validation. I was previously firing an onBlur after the text
box but now that I have three, and I need the values to concatenate
into one for the validation. Should I just fire a function after the
3rd field that concatenates the 3 values, then pass that value to the
validation function? Or is there a better way?
I was also wondering if there was something I could find like an input
mask, but something that could just "overlay" on top of a regular text
box with one value which could give the appearance of having
separations for certain digits, in this case the first and last.

Is there a way of telling the validation plug-in to use it's defaulterror messages when the title on the control is set? The defaultvalidation error messages are good for most of my cases so I'd rathernot have to explicitly set the messages for each and every one ofthem.For example, if I attach a "required" validation rule to a textbox andset its title to something, I don't want that title to appear as theerror message when they leave the field blank and I'd rather not haveto explicitly set the validation message

Having a few problems with a form validation script. Its supposed to stop sending the form if key fields are missing, but it just sends them anyway!
Below is the code i use in the header to check for blank fields:

And now the code i use to action it:

From what i can see the fields match, it all links up correctly but still it will allow blank forms to be sent.

I'm having trouble changing the font color of my labels ONLY when I stop the form from submitting due to blank fields. I'm not sure whether if just changing my CSS will achieve what I want, or am I going to have to add somethig to my if else statement, or both? I would think I would need to change CSS to :
label.onfocus {
color:red;
}
but a little confused on what else.

I have a working contact form with 3 of the fields requiring validation and they work well. I have added extra fields to the form (StatusClass, Project, CameFrom). These 3 fields return fine but I need to validated them. My problem is that the new fields don't show in the behaviours/validate panel even though they are within the form tag.
<script type="text/JavaScript">
<!--
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}

I currently have a form named "survey". I found here a JavaScript to validate my form.
I am having serious issues with this script, either it won't execute at all (the form doesn't work, as well as the validation) or the form submits without validating the form.
Here is the current JavaScript I am using.

I've literally tried everything. Read 26 tutorials, interchanged code, etc. My validation functions all work. My AJAX functions work (tested manually using servlet URL's). The second servlet validates the reCaptcha form that's generated on my webpage. After the form is validated, even if everything's correct, nothing happens upon clicking submit. I even have an alert pop up if with the captcha result, just for middle-layer debugging purposes.
I want to do all of my validation clientside; none serverside. However, going to be tough if I can't get my god damn form to submit. I've been puzzled by this for close to 36 hours straight. I can't see, and I'm going to get some rest and hope that there is some useful insight on my problem when I return.

I've set up a mock registration form page so I can learn a bit about javascript's form validation. (newbie) I want to try to attempt to style the border of a form field green when the user enters the correct info into the form text field and red on all other fields if the user doesnt enter any info into them. When i test it, enter the right info into the username field, leave the others blank, and hit the submit button it styles the username field green ok but it doesnt make the next fields (password and so on) red. just for testing purposes I've put return false on everything so it displays a message when everythings ok.[code]

I have a multistep jquery form that validates user input and then should send me an email. Problem is, right now, I can only get it to validate the first page, then it sends the email before the rest of the pages are viewed. I'm just trying to delay the submission of the form until the "submit_fourth" button is pressed. I've got $25 via paypal for the one who sticks with this one for long enough to come up with a workable solution.
Here is my code I know it's a lot, but I wasn't sure how much would be HTML code is in the second post in this thread (it was just too much to fit in one go).

I am doing a script, like:
I have anonymous function "xhr.onreadystatechange = function() {}" in the method "this.update" of an object that receives 2 arrays through AJAX. I need these 2 arrays to be assigned to this.images and this.folders, respectively, through this anonymous function. I try to use "var self" technique, but it doesn't work.

I have created my second Form to File Web Form but basically I took my First Web Form coding (with the Java Script) and manipulated it so that it suited my needs for my 2nd Form (both are very close to being the same).For some reason, I can't get my Java Script validation to take effect. I was wondering if some one could try to pin point why it isn't functioning properly? Again it could be the most obvious thing, but please bear with me as I learn.Just for a little more clarity, I am going to list the things that I have changed to possibly make it easier to pin point:[code]

How does one cause a form element to appear ONLY if a certain form selection is made before it?
That is for example say there is a form element of type Radio called "format" so only if they select format value = normal then the form input fields called URL and Name are to appear as the next choices otherwise form input field Group and checklist Places are to appear as the next choices.
