Oct 10, 2009I want to know how I can make a form validation using AJAX? I need a sample or an idea of how making my form validation using AJAX.

View 3 RepliesI'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.

Does anybody know how i check to see if the radio button is select and also can anybody tell me how i can check for an email in the correct format the function isValidEmail in the above alows emails to pass through.
View 4 Replies View RelatedI'm trying to make a username form validation combined with ajax but I'm stuck at 1 point. I need to use a var that is outside of my $.get() function so that I can add the function to the validate plugin.
This is what I have:
As you can see, I'm trying to change the value of "var result" to true, but since that is outside of my $.get() it doesn't seem to happen. I tried to put the return command inside the $.get function, but then my validator always keep saying it's a false check.
Is there anyway I can call that var inside my $.get function?
I need a sample code.It should be like when i have two text fields without entering the first one when i keep the mouse in to the second text box it should say in the red mark as in the right hand side of text box..

Ajax and jQuery is something I'm new to, but PHP, Javascript, and MySQL I'm pretty well seasoned with.For starters, I want to create a simple form where there are these fields:Name (text field)E-mail (text feld)Zip Code (text field)Cell Phone Number (text field)Phone Carrier (dropdown menu)Thing is, I want to check the database to see if an e-mail address has already been entered. I'd like for that to happen after they enter the email address and tab or click out of the e-mail text field. For instance, after they enter an e-mail address and tab to the Zip Code field, the script queries the database to see if that e-mail exists already. If it does, it notifies the user and greys out the submit button. If not, they're allowed to finish filling the form out and submit. It'll be a huge time saver if this Ajax script is in place.
View 1 Replies View RelatedI have a scenario where I have the following jquery
Code:
$("#frompdc<?php echo $JavaCnt;?>").change(function(){
var id = $('#id<?php echo $JavaCnt;?>').attr('value');
var frompdc = $('#frompdc<?php echo $JavaCnt;?>').attr('value');
var topdc = $('#topdc<?php echo $JavaCnt;?>').attr('value');
$.ajax({
type: "POST",
url: "AJ_Update.php",
data: "firm=y&id="+ id + "&frompdc=" + frompdc&topdc=" + topdc
});
And some php to insert this data
Code:
mysql_query("UPDATE TBLTRANSFERS SET FROMPDC = ".$_POST['frompdc'].", MOD_TS = '". $timenow ."' WHERE ID = ".$_POST['id']);
I'm trying to throw some validation in here which I can do in php (a language that I'm much more proficient in) but can't figure out how to get the two together. I want to be able to do a select against another table I have for both the frompdc and the topdc.
Code:
$tofpdcresult = mysql_query("SELECT * FROM tbltransferspdcexclusions where FROMPDC = '".$frompdc."' AND TOPDC = '".$topdc."'");
$tofpdcnum_rows = mysql_num_rows($tofpdcresult);
And if it exists I want to give a popup message to the user as well as blank out the field.
I'm struggling with two things:
How do I get ajax to run two queries and return the results to a popup window?
How do I blank out the field in the form?
I'm trying to create a simple registration form with ajax validation. I've got the form working almost how I'd like... a message appears on the page with the errors for each field entered incorrectly.
The problem is all the error messages appear in one div together and I would like to have each field have its own div containing only its own error.
I think I need to wrap my error messages in xml and use something like this -
Code:
- but can't seem to get it working
Does anyone know how I should modify my code to do this?
Attached are the 3 I'm currently using
And Here is my code for my ajax page only.
Code:
I have a problem where if a form submission (set up to submit via AJAX) fails validation, the next time the form is submitted, it doubles the number of post requests - which is definitely not what I want to happen. I'm using the jQuery ValidationEngine plugin to submit forms and bind validation messages to my fields. This is my code below. I think my problem is that I need to unbind from the validationEngine plugin when the form fails, but I can't figure out how to do this.

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.

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:

This is in regards to Jrn Zaefferer's plug in.How do you customize input validation so that I can remove foullanguage?So that first name or last name doesn't have "fck you" or something
View 2 Replies View RelatedI'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?
View 1 Replies View RelatedI 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
View 1 Replies View RelatedI 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.

the validation and CSS work. I just can't figure out how to make them work together.
I have a list of radio buttons, all with the same name, and each has adifferent value.I want a validator that tests if one is picked.
View 2 Replies View Related[URL] I'd also like to use this plugin, so I don't have to create complex validation rules. validation plugin [URL]Trouble is, I can't figure out how to prevent form submission without first checking to see if the form is valid. My attempts so far have been based on using submit() to prevent submission of the form if validations valid() method returns false. But this doesn't seem to work. If I use ajaxForm, the submit() function seems to work differently. A form will still be submitted, despite a return false. validate has a valid() method that returns false if the form fails validation. How can I submit the form only if valid doesn't return false?

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:
Code:
And now the code i use to action it:
Code:
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) {

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 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]
View 3 Replies View RelatedI 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 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]
