I have a shopping cart with a quantity field. I also have an update button that updates the totals. Myquestion is how can I use jQuery to check the quantity field when it loses focus, to check the value against the database and the Instock field. If gt then display a tooltip (or something) and not allow the form to be submitted. The problem is the field is called sel_qty for each product.

I am a php programmer and not a Javascript programmer and I am trying to help a friend out with his shopping cart. The original programmer (who wrote this years ago and is no longer around) has a button that looks up the quantities in the database for the submitted items, and then displays a prompt if you selected a quantity that is less than the minimum purchase amount.The issue is if the user enters a smaller amount than allowed and hits the enter key instead of the "Buy" button, it allows the order.how to use the current code to also check for an Enter key submission.I can handle the PHP and the db lookup for minimum quantities. Here is the page code and the Javascript code.
Code:
<a href="javascript:checkQuantity(document.form<?php echo $formCount; ?>,
<?php echo $row_rsProduct['lotQty']; ?>,

I have an online shopping cart and some of the products are sold in boxes of 6. So I am trying to write some code that will alert the customer if they have entered a quantity that isn't some multiple of six.
I've tried using the modulus operator as well as dividing by 6 and then checking to see if the result is a whole number but inevitably the alert box pops up no matter what I enter.
This is what I'm trying to use now:
Is there a better way to check if the entered quantity is a multiple of 6?
I am having trouble making a website for a vacation rental I pieced this javascript code and form together with a simple goal in mind: -to have 3 checkboxes each with its unique variable
weeks: 2,000
weekends: 325
weekdays: 275
-to allow users to check one or more of the checkboxes, and multiply it by a quantity they choose (ie "I'd like to stay for two weeks (2 x 2,000=6,000) and one weekday (1 x 275=275)
-finally, to add up the totals at the end (6,000 + 275=6,275)

Does anyone know is it possible to check if ajax call was redirect? i mean I connect by Ajax to one URL but I'm redirected to other url. Is there a way to check that my request was redirected? this situation happen when some urls are only accesible when you are logged (i mean you have session) and if you losed session you are usually redirect to other page. But I don't know is it possible to check that my call was redirect. For now wheatever my AJAX call was redirect or not i get status 200 (it's OK)...
View 1 Replies View RelatedI have two AJAX commands. One creates a list of items, the next highlights a specific item on that list. I don't want to combine these two commands because I often use them separately in different functions. However, the first command - the one that lists the items in an innerHTML - must complete before the second command is called. I used to just set a few seconds (as you'll see below) before the next command was called, but now the list is growing longer, and it no longer works. Is there some kind of command to only execute it when the previous command is ready, like "onReadyState"? Code:

I've created a registration form with sponsorship options hooked to checkboxes. My original form used ASP to keep values in hidden fields to use for totaling everything at checkout time.
Now I'd like to use PHP and Ajax to place the value into the text field related for each option checked.
I'm able to do that making an Ajax call. My problem that I need help with is this: If the visitor decides to uncheck a sponsorship option, the value placed in the associated field remains on the form. How do I replace that value with a null or empty string if they decide to uncheck their original choice?
I've tried JavaScript to no avail so far, both in the client side and server side code. I'm very new at this and I need help. Will jQuery work without having to change a bunch of code?
The general framework is a simple user login function. The user name is selected and a password entered as usual. The function grabs the element values and passes them to a php page that queries the database. An AJAX call returns the password to the function and then I want the innerHTML to be a choice of two web pages, depending on success or failure of validation. There are existing AJAX functions available on the internet but they are overly complicated for what I think should be a simple, quick to load function.
Where I am stuck is that the standard procedure to make an AJAX call is the browser window event. How do you make the call from within the function? I have tried creating two new variables, "success" and "again" to replace xmlhttp, but still stumble on the event to assign a value. I left the blank password protection (if statement) with that variable to demonstrate what I mean.
I've put in my code below, which is in development and successfully alters the innerHTML text depending on user input but I can't figure out how to insert the relevant php page. I have '// out' the testing bits, but left them for info. (I have tried full 'scripting' as the innerHTML, but it's messy.)
I'd like to call a function to check if a div with id content has a <h1> tag and if so change the divs background colour.
View 7 Replies View RelatedI have a website using jQuery that for the most part works fine, but it contains a very large form with a lot of fields. I have an option to save the settings from the form and to load and retrieve them from the server. The problem I'm running into is that the loading settings involves changing so much in the DOM (the form is huge and contains a lot of fields) that it seems to be freezing up on some browsers or timing out. I can't reproduce this on my computer (although it does take awhile to finish processing) but I've gotten enough reports of the problem that I'm looking for some advice as to how I can speed it up some.
The site is [URL] I've tried to speed it up by caching a good chunk of the selectors I'm interacting with and I'm using IDs to access the fields in most circumstances. But I'm not sure what else I can do to really optimize the loading. how I can go about improving on the load speed?

Is there any way to use jquery.validate to check if any field from the form contain HTML injections?
View 3 Replies View RelatedI am using jquery.validate.js for my validation. I need to validate some dynamic input fields. By using class now I am able to validate that. Here my problem is to validate for the file extension.
For static files I use as
file: {
required:true,
accept: "png|jpg",
},
How to write the accept validation for dynamically generated input fields. Below is my input field where the ID and name will change for every input field.
<input type="file" id="tval_1" name="tval_1" class="required accept" />
I have already done a number of things with Jörn's validation plugin and I'm excited about its features. But here is my question: how do I validate a field so that it fits the two following conditions: it should be an integer and should not be equal to zero? So, if a user enters "0", it should be error; if he/she enters "12.5", it should be error also; but "-3", "125", "40" are OK.

I wrote the following code with Dreamweaver:
If I run it in Dreamweaver It works and the alert success is raised, but If I run this code into Safari or Chrome the Error alert is always raised.
My goal is to get some HTML content including some UI widgets and other stuff via an ajax call. To clarify my goal and the strange behavior, I attached some HTML files, that you can run for yourself. Open the index.html will show you some UI widgets, which are pulled from the ajax.html via ajax. When you scroll to the bottom you can see the same content inserted a second time. But this time, the widgets are not "rendered". It looks if the "button()" calls etc. are not executed.
The only difference is the way I insert the result of the ajax call. The first time I insert the hole content received by the ajax call, the second time I only insert the content of a special div. The goal in this is to get various chunks of content with one ajax request and replace "div#one" and "div#two" with different parts of my site. Which is not working. Is it generally okay to receive html content which has some script parts to be executed via ajax and what is wrong with my second approach?
I'm currently using the dialog functionality (modal form) from UI library to submit data to the database. All the validation checks have been running ok until one of the validation checks requires a ajax call to check if a username exist in the database. I'm fairly new to both javascript and jquery so this could be a fairly basic blunder. Initially, i thought it was an synchronicity problem, but I changed the $.ajax async option to true but still no joy, so maybe it something to do with scope etc?
Here's the code:
function checkIfUsername(){
$.ajax({
type: "POST",
url: ""+CI_ROOT+"index.php/admin/check_if_username",
data: ({username: username.val()}),
async: false,
dataType: "json",
success: function(data){
returnUsernameBool(username, data);
}});
}function returnUsernameBool(o, data){
if(data.bool == true){
o.addClass('ui-state-error');
updateTips("Your username must be unique");
alert('false'); //this works
return false; //still can't return bool
}else{
alert('true'); //this works
return true; //still can't return bool
}}
bValid = bValid && checkIfUsername(username);
alert(bValid); //still gives undefined

I'm an experienced programmer, but I'm fairly new to web development, so I am having trouble interpreting this error. What have I done wrong? Is this the proper way to call a PHP script with AJAX?
I have a page that creates one unordered list from the contents of another list. The second list is created from a database query and is hidden on the page. I have written a JQuery function shown below that does an AJAX call which causes the hidden list to be created and that is working perfectly. The problem is that when the code following the AJAX call is executed it doesn't see the hidden list. The alert message displays 0 the first time. clicking on the Load button a second time results in the first list being displayed. If I click on the Load button a third time, the previously loaded list is displayed; click on a fourth time and the new list is displayed.
In other words, it takes two cycles to display the correct list. I am at a loss as to what might be the problem. Other than this issue the code does what I need it to do.
$(function() {
Strange behaviour: User enters text into textarea - text includes URL with protocol e.g. [URL]. JSON call fails with 403 forbidden. It seems the the serialised content is being interpreted as a cross domain call (my guess). Any other text works - Even if the user enters "http://www.u", but as soon as the input qualifies as a url, I get a 403.
The code extract:
var formText = $("#contributioncontrol").serialize();
$.getJSON('[URL]',formText, function(response) {
if (response.ERROR != true) {
var output = response.HTML;
$(output).hide().prependTo("#results").fadeIn("slow");}
}
If the user enters http://www.url.com in the textarea on the form then The request looks like this: [URL]. The '/' chars in the line above are replaced by% 3 A % 2 F % 2 F (without spaces - Don't know how to stop browser interpreting the encoded stuff).
And the response like this:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>403 Forbidden</title>

<h1>Forbidden</h1>

View 12 Replies View RelatedI am using an ajax call when clicked on a link... It asks whether you want to continue or not and if you say "ok" then it uses a perl script to delete something from the db.[code]So I was able to call confirm on each of those links and if agreed use an ajax call to a perl script to wipe the user from database. The thing is that I had to usereturn false; in the end of my js call (after ajax) otherwise the link would take me to the script, which I dont want to. I want to remain at main level (to be able to see all users)... Now how do i refresh the page after such deletion? Lets image this scenario:
User clicks on link_to_delete Brad => confirm => he confirms by clicking ok => ajax call to perl script that handles the deletion of Brad => return false (I want to remain at index.pl) => HOW DO I REALOAD INDEX.pl ? I deleted Brad but I can still see him cause the page has old data.
