Skip Validation On Hidden Forms
Aug 11, 2010
In another thread I found that a good way to show and hide parts of a form based on previous entries would be as follows:
function showhidefield (method) {
var hideablearea = document.getElementById("hideablearea");
var hideablearea2 = document.getElementById("hideablearea2");
var hideablearea3 = document.getElementById("hideablearea3");
switch (method) {
case "1":
hideablearea.style.display = 'block';
hideablearea2.style.display = 'none';
hideablearea3.style.display = 'none';
break;
case "2":
hideablearea.style.display = "none";
hideablearea2.style.display = "block";
hideablearea3.style.display = "block";
break;
case "3":
hideablearea.style.display = "block";
hideablearea2.style.display = "block";
hideablearea3.style.display = "block";
break;
default:
hideablearea.style.display = "none";
hideablearea2.style.display = "none";
hideablearea3.style.display = "none";
}}
I know how to use javascript to validate that the forms are infact filled but how do I make it so that it doesn't scan the hidden forms. The only way I could think of would be a huge bunch of if statements. Is there any other way to do this?

I've an input field in the form which is displayed based on the user selection. Initially it is set to 'display:none' and I do have a validation rule for that field.
How do I skip validation on this hidden input field and only validate when its displayed on the page.

I am using the validate plugin with the defaultvalue plugin (empty fields given a default value and class of empty), and would like to use it together with the validator plugin. Is there a way to mark required fields with only the default value (and class empty) as invalid on submit?
E.g.: First_name field is required by validate, has a default value of "Enter your first name" and class of "empty" - how can I get the validator to mark this as invalid?

I'm trying to solve problem I'm having with my iframe and forms. I have a form that is brought into a hidden iframe. Now I can't seem to get the form to submit? I am guessing this is the case because of how the content in the iframe is brought into the main page. I'm not very good with scripts. Here is my page: [URL]. The form is on the reservations page. This is the form that won't work.
Here is my code:
This is in the stylesheet:
#buffer { position:absolute; visibility:hidden; left:0; top:0 }
div#display {
margin:0 0 0 0;
/*margin: 2em 0;*/
/*border-top: dashed 2px #999;
border-bottom: dashed 2px #999;*/
padding-bottom:6px;
display:none; /* until loaded */
}
This is in the main page (which calls the iframe)
<div id="display"></div>
<!-- onload attribute does not validate but is included here rather than assigned via JavaScript to maximize cross browser support -->
<iframe id="buffer" name="buffer" src="home.html" onload="dw_displayExternal()"></iframe>

I am using a script that tabs to the next field on Enter, but it doesn't have logic to deal with hidden fields and instead stalls with "Error: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus."
How would one implement a simple checking mechanism to skip focus on hidden fields and the like?

I have a database that shows about 5 to 10 recorrds on a page that contain forms for the user to fill out. The number of rows is unknown and depends on the user query.On the page there can be 2 or 10 records displayed ..each containing a form that needs to be validated.How can i use that. The IDs of the elements would have to be generated dynamicly i suppose. Anyone of you got an idea how to do that ?

I know that this must be quite trivial to most of you, but my skills
in JavaScript are weak.
I am looking for a way to validate all forms throughout a website
through one validation script.
How do I determine the form's name (or id) value to implement
conditional validation?
i.e. if (form1) { validate like this }; if (form2) { validate like
this };

I'm currently working on a website called 'eXtreme Gaming' I've almost completed it, apart from two things.
- Adding two values on my checkout page for the Grandtotal (I've tried everything, but I'm too much of a noob and have probably missed something small).
- Validation of forms (I don't know where to start here, I've looked on w3schools for tuts etc but I'm having difficulty incorporating it on my site)

I'm brand new to jQuery, and I am really interested in learning about it because of the potential it offers to enhance my webpages. To give you some background, I am self-taught in PHP and MySQL...not on a master's level, but I have designed and built database-driven sites with success and am confident that I can learn jQuery if only I could get pointed in the right direction. I have perused tutorials, links, forums and recently bought the jQuery Cookbook (I needed SOMETHING to go on and it was one of the few jQuery books at the local bookstore that felt as though it would be of help). My problem is, I am finding gaps in information that, to me, are critical to learning. I am looking for a nut-and-bolt approach, 'Do this, then do that' not the typical generalizations I keep encountering.
All I want to do to start with is to remotely validate a two-item form, you guessed it, username and email, against the contents of my database (the info for the validation plugins is just as vague and general). That's it. But the tutorials and examples are vague to me, and in one instance, a link was posted offering to display the server-side validation code used and the link was dead. I can't be the only person here who is stonewalled by these thoughtful, yet overly-general tutorials and books. if any of you have suggestions where I can find a concise, true step-by-step tutorial or book, I would love to know. Right now, it's just one frustrating day of research after another.

I have built out a fairly rhobust app using jquery and jquery-ui all was going well until we started to bring different screens together inside a tabbed interface. Seems that now when we execute our validation code on one form its checking the fields of all other forms on the page.All of my forms do have unique ID's and all elements within all forms have unique ID's.My understanding of using this.find inside of the submit event was that it should only find the forms elements am I wrong? Method that performs the actual validation:
function validateForm(event){
var allOk = true;
$(this).find("*[validation]").each(function(){[code]....

JQuery newbie question re using validation plugin with Django newform.I have a simple email feedback contact django form that I wanted toenhance with some JQuery validation. I created a standalone (NonDjango) version of the form and it works correctly.However when I create a Django version of the form the validationrules seems to be ignored and the form is always posted - I wouldexpect the form to fail, and never post. One difference (not sure ifit's siignificant) is that the Django forms are created from classes/templates and render as tables. However the exact same HTML code worksfor the basic form.I'm now thinking that there must be something different re how thesubmit is being processed for the Django form - but I'm stumped.

I've used the excellent validate plugin (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) to add JS validation to forms. I'm aware there's a built-in setting to validate an email address. However, I'd like to validate a list of email addresses, and I don't think the plugin contains a built-in solution. What's the best way to implement this?

I know that Javascript is client side, but I'd like to know the best way to populate HTML drop downs in real time based on information typed in the other HTML form fields with information found on the server as opposed to the client.For instance if a user wants to select certain files located in a directory on the server, as they type in the pathname supposedly containing the files the drop downs continually refresh themselves with the server files listed in that directory (if it exists, and apache has permissions to see what's inside) as if it was showing client files instead.
What would be nice is if my browser could continually query the server for some of its private information and not have to refresh itself to obtain it, whether that means the server-side would have to continually refresh itself makes no difference to me as long as the client-side doesn't have to. But I guess this is not possible because no matter what you would have to at least refresh the client-side page once?Submitting the form to a CGI or PHP script would not work because I need this functionality to help populate the form BEFORE I send it.I would like to not have to press a button to update the form every time I change the pathname and need to update the drop downs since this would be annoying.

I have an order form where a customer can select a number of artwork prints supplied by different artists and suppliers. The name, price, postage amount and other details for each of the prints are held in a table in a MySQL database. As postage amount may vary between prints and suppliers of the prints we must have the customer select postage per print - not the amount just yes or no. The customer may select as many of these prints as he desires - printa, printb, printc, printd etc. through to printz. Many of the prints are provided by separate individual suppliers and must therefore have postage paid for each ordered print and this is automatically added by the order form. However some prints are provided by the same supplier and only one postage fee needs to be chosen (yes or no), so these are not automatically added and the customer must choose to pay postage on only one of the prints (not all 3 if he orders 3 of them).
So for postage purposes I have a postage code on the table in the MySQL database. For example printa, printb and printc are all supplied by the same supplier so each have a linked postage code of A. Similarly others may also be linked using different postage codes e.g. printx and printy may have a postage code of B. So whenever a customer chooses a print that does not have a linked postage code then the postage fee is automatically selected for him and charged to the total. However where prints are linked to the same postage code we must allow the costomer to select postage (yes or no), but we must force him to select yes or no for at least one of the linked prints.
So to do this I need a javascript validation alert to force the customer to choose yes for postage for at least one of the prints, not necessarily all of them, where they have a linked postage code. To do that I can add the the postage linked code as an array for each print selected to a form hidden field so that my javascript can use the field as follows: <input type="hidden" name="postagearray[]" value="<? echo $postagecode; ?>">

I have a user name, password, phone number etc., that all need to be validated before being submitted. The functions filter out the unwanted characters and null and zero length strings. I did have a pop up that listed the errors but I would prefer them to be listed below the log in screen that is a hidden div.I cannot get it to work.The validation works fine,

I'm developing sort of a do-all javascript required form field check (which was developed long after the pages were developed). It uses a lot of getElementsByTagName so it's creating several NodeLists. One of these nodelists contain all the divs, those showing (display:block) and those hidden (display:none). The function checks only the divs that are visible.
This is my first experience with NodeLists so the first thing I tried was removeNode() on the hidden divs. This doesn't work because when you return with required field errors and try to make the hidden fields appear I believe there are errors because the hidden divs were removed from the DOM.
I've tried a few other work-a-rounds but it's getting to be afternoon and I'm turning to you guys for help! Is it possible for me to just skip forward to the next Node in the NodeList? I've tried nextSibling but I guess I'm calling it on the wrong Node.

I'm no good with Java but I need to set a due date and get it to count past the weekend. I had a couple of Java classes forever ago and it's not my forte, but at any rate I have to adjust the code in a program that I maintain at work. I need to keep it simple because in 6 months when I need to update it I will never remember what I did because it's not something I do enough to retain the skills.
var today = new Date();
var duedate = today.setDate(today.getDate()+2);
taskform.datefield.DataValue = duedate;
I tried an if/else then a when and I bombed at both I figured I was going to have to actually write something. I'm smart enough to know I won't get this on my own, especially if I have to get an array going.
