JQuery :: Form Validation Combined With Ajax
Apr 12, 2011
I'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 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'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 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.

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.

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.

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'm not very experienced with jQuery yet and after a while of trying and searching I decided to ask for help here:
I'm using jCarousel Lite, the "Custom Widget" scenario (click in the list on the left)[url]
When clicking on a image in the carousel, the larger image is shown immedeately. I'm trying to achieve a fadeout, fadein effect. Doesn't need to be a crossfade, a fade out to white, fade in from white is fine.
My 'bare' code (this works, with instant showing of pictures, without any fades)[code]...

I have a program that allows the user to input a product number from 1 to 5, and the amount of each product number sold. After all values are added, the program is supposed to calculate each product's total retail value, as well as the total retail value of all five products combined. The program runs fine, up until the end. I got all my alert boxes working, and the program is doing the multiplication as it is supposed to. However, when I get to the end, I receive "Last weeks total retail sales are: $NaN".
My code:
var productNum;
var quantity;
var prodPrice1 = 2.98;
var prodPrice2 = 4.50;
var prodPrice3 = 9.98;
var prodPrice4 = 4.49;
var prodPrice5 = 6.87;
var total1;
var total2;
var total3;
var total4;
var total5;
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity1 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity2 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity3 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity4 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity5 = window.prompt( "Enter the quantity sold" );
total1 = document.writeln("Total for product 1 is $" + (prodPrice1 * quantity1) + "<br />");
total2 = document.writeln("Total for product 2 is $" + (prodPrice2 * quantity2) + "<br />");
total3 = document.writeln("Total for product 3 is $" + (prodPrice3 * quantity3) + "<br />");
total4 = document.writeln("Total for product 4 is $" + (prodPrice4 * quantity4) + "<br />");
total5 = document.writeln("Total for product 5 is $" + (prodPrice5 * quantity5) + "<br />");
document.writeln( "<h1>Last weeks total retail sales are: $" + ( total1 + total2 + total3 + total4 + total5) + "</h1>" );

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 few html fields in a form that use PHP in order to calculate a combined value and then inserting it into the database. However, I would want that value to be displayed to the user as well before they insert it, just so they can verify that the value is correct. But how do I go about and do this?
It is probably very simple, but I'm a PHP programmer and have very little knowledge of JavaScript. Basically this is what I would want:
<field 1> -20 +(or -, depending on user input) <field 2>
Result of that to be displayed in <field 3>
However, I only want the -20 to calculated when something is entered in <field 1> so that it does not say -20 in the output field before the user even started typing a value.

I like the looks of the validation engine plugin, but I can't figure out one thing... For a particular form field, I need to use an Ajax service to validate the data. I have to pass the value of the text input, of course, but I also need to pass a couple of other key=value pairs along with it. In the file with the selectors there's the option to add extraData (like extraData="name=eric") but I need to set these parameters based on some dynamic info.Is there a way to pass extra information to the ajax service?

I've been searching for a resolution to this issue for hours trying to customize my page located at [url]
Specifically, I'm trying to figure out why this line of code is not making my images display in the background:
Original plugin script provided here: [url]
<script>
I made adjustments with my image references that are all located in this directory: [url]
Problem: No images load, and I believe I don't fully understand the .appendTo tage.. I don't know if #body is correct. The author of the plugin assumed I understood the relation. Also #homePage may be incorrect as well.
Additionally, I found another plugin that worked for placing an image in the background (not random), and the background image would scale to size, according the users window. I loved that and it worked, just wanted to add random images to the same script.... first things first... I can't even get an image to display at all with the above code.
In case you wanted to know the script I was using to scale the background image, here it is below (although, as you will see in the code for my site - this image feature is disabled as I am trying to make adjustments).
code for image solutions used:
HTML
CSS
If I can get this second code to work with the random image plugin.
