JQuery :: Validate Required Fields Before Form Submit?
Oct 9, 2009
I am trying to use jquery: validation plugin by Jörn Zaefferer. Which works really well I have to say. The one limitation I am trying to work around is how I can run validation for required fields before I submit a form. At the moment I have to submit the form before I see the error messages for required fields I would like to see them prior as the user tabs through the form.
I would like to disable the submit button until all fields have been success. I have been looking for examples of call backs but could find anything I could use.
How do I disable the submit button if all required fields in a form are not filled in? Say I have a form with Name, Age,message, and email. Name, message and email must be filled in or else the submit button will not show or will be disabled and then enabled once filled. If the fields are filled in then the submit button will show. If the fields are filled in but then one is deleted then the submit button will hide. Ideally if I can have it disabled that will work, if not I will settle on hide at this point.
I have a form that has 4 "required fields" that validate using JS. I am now trying to add a 5th "required field" (the difference is that this field is a "radio button input as opposed to a text input).
I have it working so that when the 1st radio button is selected, the form will go through. However, when the 2nd radio button is selected, it comes up with the "please fill in all required fields" error.
Here is the JS I have so far:
HTML Code:
I tried adding the 2nd radio button value like this:
HTML Code:
(document.indiv_reg.skill[0].checked =="") || (document.indiv_reg.skill[1].checked =="") But when I do that, then even when the 1st radio button is selected it comes up with the "please fill out all required fields error".
My CMS generates forms in a specific way, and I need to change the way validated fields are selected. I'm using the validation plugin: It identifies form fields that have the "required" class. My CMS generates required elements like this:
<div class="required"><input /></div>
I was hoping this can be easily changed in the plugin syntax, but I can't find any reference to such a change (to select the required fields using this selector: ".required input"[where input is any form element])
There are two input fields in a form, but only one of them is required, they are not required at the same time. Either A or B is required. ( A is required OR B is required). In other words, a user can input data to field A, or he can input data to filed B, but he can not input data to Both A and B at the same time. How to implement this constraint in Jquery form validation?
I have some fields that require no validation and some that require it. The valid css I made in green color. Now when I click on submit the validated fields show green and the non requested are left yellow that I use. Is there a way to somehow on submit make all the fields to have valid class?
I need to do a clientside check of a form to see if a "required" multiselect list and a checkbox have been left blank or not. To clarify, the user is required to select either one or more options from the multiselect list, the checkbox, or a combination of both.
What they can't do is leave both of them blank. Both the multiselect and the checkbox pass values to a PHPList script on the server as if they were one multiselect with the name "attribute17[]".
***Disclaimer - I am a total javascript noob and am piecing together examples from several days (and long nights) of googling.***
I'm dealing with a very long subscribe form, and so far I've been successful with figuring out the code to validate emails, select dropdowns, and checkboxes. This combination multiselect and checkbox is the last piece of the form that is giving me trouble. Hopefully somebody here has a solution.
For simplicity I've reduced the javascript and the form down to just the part I'm still having trouble with. Here is a piece of the javascript that I'm trying to use:
Code: <script language="Javascript" type="text/javascript"> function checkform() { if(document.subscribeform.elements["attribute17[]"].value == "") { alert("Please select your Primary Work Locations");
It's beginning to get confusing as some code seems very complicated. I simply want four fields to be mandatory when filling out the form - so if one or more is not filled in, an alert appears saying 'Please fill out all required fields' (or something to that extent) before it will process. I understand that I need to include Javascript within the Head secion of the page and corresponding html and javascript within the contact form itself.Required Fields are: Name, Address, Area Code and Phone.<div id="main"><p>Please feel free to contact us with any query. see the <a href="services.html">Services</a> page.<br />All fields marked with an asterisk (*) are required.</p>
I have a form which I need to add an ajax loading image.My question is how do I connect it to the camcheckrequired function so that if there is an error the image doesn't show?
Code: <script language=javascript> function camcheckrequired(theform) {
I have a simplified version below of a multipart form. There are two steps and two tabs. I want the user to enter their username and email address and click 'Next' which will validate to make sure those fields are filled in, then activate and advance to tab #2 (Step #2) of the form, where they enter their credit card information.
I am having difficulty because username, email and credit card are all in the same form and I need to only validate certain fields on each step of the form. I was thinking I could make a function when the 'Next' button was hit that would validate the first two fields?
Here is what I have so far. I have a 'Next' button which activates and advances the tab to Step #2, but I need to work some form of validation into it before it advances. At the bottom of the page I have a 'Submit' button which is just so you can see that the validation is working if the form is submitted. I just want the 'Next' button to activate a function to only validate the fields on Step #1 (username/email).
I hope this is the right place for my question. I have a working form and all iss great using this jQuery Form Validation PlugIn from brassistance. Now I got in trouble by having a Form which will get extended by user inputs. To explan in detail: I have a Form with static fields and so on. But then if the User selects in the form the amount of Persons, I append Name and Surename Text Fileds to the static form and give the form fileds dynamically generated names. now have the problem to validate the dynamically generated text fields in that form!
I have a form with a series of fields. Only certain fields need to be validated when certain buttons are pressed. The reason for this is mainly because I had to build my own wizard style setup with jquery so, even though it's one big form, only certain bits need to be checked as they progress. I tried to tweak the accordion example given by the creators but it can't really apply to my scenario.
I've simplified the code down a bit and it is behaving exactly the same way as the big form...which is to say it's not behaving at all.
In this code, I want it to only validate field txt1 if button 1 is pressed and text2 if field 2 is pressed. One odd thing to note, when I set it up exactly as the site recommended with one big mass validation and such, it would only acknowledge the existence of the first field even though they both had class="required" on them.

I'm trying to validate a form with on submit if statement, unfortunately this code only pops up platenum label or motornum label depending on which is filled, but if both are not filled, it only shows one.
</html> <script type='text/javascript'> function formValidator(){ // Make quick references to our fields var name = document.getElementById('name'); var addr = document.getElementById('addr');
I am pretty comfortable with jQuery and the validation plugin as well.
I am having an issue where:
User clicks a button it opens a lightbox (I am using Fancybox) - a form appears inside the modal. The data is submitted via AJAX and I am trying to validate the form before the form within the lightbox is submitted.
My button with the click handler right now does a GET to a server to send the data. Along with some other JavaScript. What is the best way for me to validate my form within a lightbox, and submit after it validates. Sending AJAX.
I have a form with multiple submit buttons. <form action="" id="myForm" method="post"> <fieldset> <!-- various input fields --> <button type="submit" name="Exit">Exit</button> <button type="submit" name="SaveExit">Save & Exit</button> <button type="submit" name="Save">Save</button> </fieldset> </form> When the SaveExit or Save buttons are clicked, the form is to be validated. When the Exit button is clicked, the form is NOT to be validated. How can I do this with the Validate Plugin 1.7 from [URL]. Is this possible?
I have a page here http://183.78.169.53/scv/addRoute3.php. What is does it check if either of the second/third dropdown list is not selected then minimal the third dropdown list is required. I have function like this. What it does when there is change in the second column dropdown list > 0 then I want to make the third column dropdown list to required false but when I submit it still shows me the error message "This field is required".
Code: function handleDwellTimeHourUpdate(index) { //alert("First or last row");
I am using jQuery AJAX to submit a form. When the data has been validated successfully and processed, I want to clear the form, but I am unsure how. I have been trying to make it work for a few hours now.
I am showing status messages in the container below:
When everything was successful, it looks like this:
And here is the simple code I use to clear the text fields:
What I need is a way to check if everything was successful and if so, then run the code above. I tried to do it in a few ways, but it kept clearing regardless of the status.
I have a form on my website that takes registrations for my classes. The form currently is sent to a php that checks for empty fields. If all is good, they are passed to a thank you page. If any empty, they go to a page that reminds them to fill in all required fields, where I've provided a history-back button. Problem is that 1) the captcha image isn't refreshed, and 2) with 14 fields, they have to find the missed field!
This is where I thought that This Script would work great. It adds a "sentence image" in red when a required field is missed. This would keep the person on the same page, and highlight the missed fields!
My Problem; I've tried to adapt the script to my already existing form, but when I click the submit button, I quickly see my tables "expand" from the inserted image (haven't sized the image to fit yet, so it enlarges the table), but then immediately proceeds to the php script!
Below is the code between the head tags but only for field-1 for now!
I have a form built and on the onclick event I validate all of the fields and then if the form is ok, on the submit event I run a javascript function to set a cookie and download a file from the current window.
I have a cgi script provided by my web host to send the contents of the form through email but they only show me how to use the cgi script to send email through the submit event of the form.
So I am trying to validate many input fields inside a form before I send it off to mysql.
The page link is: [URL]
I am 99% sure it a JavaScript issue and I am a beginner with JS. My JS code is as follows:
function validate(form) { //Pull values from form var email = form.user_email.value; var confEmail = form.conf_email.value;
[Code]....
I'm trying to change the color of the labels according to what input field is wrong. It seems to loop through and keep my labels black. It shows the email red for a millisecond though.
I'm redesigning a large website right now, and the problem i'm having is that there is already a CSS class called "required" that has been used extensively all over the site. However, I want to use the jQuery.validate.js for the forms. is there any way to override this?
the validate plugin at the form at the below URL is validating as true as long as the first required input is valid even though subsequent required fields are invalid. It even gives the invalid class to all fields correctly but the submitHandler function is triggered anyway. I have an alert trigger when the form successfully submits and a little more output for firebug if you want it. [URL]
im loading data via json dynamical from the server. Now i try to optimate the speed of my application and so i want to disable the validate of the fields during the data loading from the server.Is there a simple solution to this? like validate = false
