JQuery :: Change Field Value With Ajax Call Based On Checkbox State?
Mar 31, 2010
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?

What you can see is that I have a bunch of images which form a chart, each of the images has multiple classes.I want to write a function which when called fades in/out images dependant on whether all related checkboxes are checked or not.Checkboxes are related to the images by id on the checkbox and class on the image, as I'm sure you can see. I will be calling this method each time a checkbox is checked.

I'm trying to get the two followup questions underneath the checkbox to show up only if someone places a check there, but for some reason the way I've got it set up now it's simply hiding the area I want to show up altogether, and the checkbox has no effect on it.
Rather than waste tons of space pasting it here, here's the pastebin: [url]
Alternatively here is the live version:[url]
I'd prefer to have the form collapse when the additional questions are hidden, though if i can get this working at all.

Here is what I'm envisioning: The user selects a state, then in the 'Cities' box, he starts typing the name of his city. However, it autocompletes the name for him based on the state he chose. So if he chose California and started typing in "Los Angeles", it would autocomplete "Los Angeles" for him. Does that make sense? Is there a script out there that can do this?

I've created a checkbox and radio button replacement plugin (URL...), and I'm trying to be as thorough as possible.One situation that I have yet to solve is if a button is given the attribute checked="checked" through some external function. I'm not sure of how to detect this event so that the replacement image is also updated. The .change() method only works when the user actually clicks on the button.The reason I am trying to work this out is because I am adding support for disabled buttons as well. From what I've seen, there are plenty of situations where a button is disabled until a user either selects something else, or fills in required info, etc., and then it is enabled (most likely through the removal of disabled= 'disabled '). If the developer has already worked that in, I don't want the implementation of my plugin to affect that. It should just work automatically.I do check the states on page load, but i'm not running any sort of loop to constantly look for changes.

I have 6 horizontal navigation image links on top of my site. The regular images are black n white, but on the hover they transform to a colored image. Each image leads to a different page on my site, I'm wondering if I can make the image corresponding to that page light up whenever on that page.

On my index.htm, I have a horizontal cell named "memberarea" which originally shows username & password input fields. After the user logs in, this area changes itself to a "Welcome Name, Lastname" field. I want that this cell displays again the username and password input fields in case of the session of the user has expired. I have tried it with the following code (within the Iframe in index.htm):

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.)

To say I'm new to JavaScript is a bit of an understatement so bear with me. I have a site set up with a variety of layers of toggles. When you enter the site all of the items are collapsed and you click the headings to expand. Each of the toggle-able items have ids. It works great for users who start at the homepage.
However, when I send people to any of the inner topics, all they see is the initial collapsed state of the site. I want to be able to provide a URL that will set the toggle to open, and show all of the content for that section on entry.
Here is my code and js, can anyone point me in the right direction?

I have a form with 3 checkboxes. When user checks one of the boxes, additional fields show beneath the checkbox and the other 2 checkboxes are grayed out (locked). What I want is that when a user checks a checkbox, not only does the other 2 lock, but the text associated with them turn a different font color. I want it to appear as if the other checkboxes and text are being grayed out. BTW - I don't know any java, someone helped me with this and gave me this code so please try to be as specifica as possible.
For the lock function, I am using the following code:
<script language=JavaScript> var U=0;L=1; // (U)nlocked & (L)ocked
function doIt(_v)
{
if(eval("document.bgcheck.c"+_v+".checked"))
{
if(_v==2){lock(3);lock(4);}

Currently on my page [PHP5] I have a checkbox & a input button (among other things), the button text now is hardcoded to "Next" but I need this to change based on the status of the Checkbox (cBusAcc). For example, when cBusAcc is not checked the button should be "Create", when it is checked the button should be "Next".
And this change should occur without the user needing to press on the button, just check/uncheck should change the button test...
See the code I have so far below...
...
<input type="checkbox" name="cBusAcc" id="cBusAcc" />
<input name="signup" id="signup" type="submit" value="Next" />

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 have a form that captures member registration details. In the admin section .. I would like to change the Status field of a record/s from NEW to PAYMENT DUE after 14 days from the data of submission. The status change should automatically trigger on the 15th day.

This function is getting called as it should. the line "if ($("lumode").attr('checked'))" is not detecting the state of the checkbox properly. It always returns false so mode never gets set to 'all'. (#lumodestate is a button I am using to test the function).
$(function(){
$("#lumode").click(function(){
mode = '';

I have a little problem with saving a single checkbox state (check or uncheckd) for a session with jQuery.
I did find similar problems and solutions but i couldn't apply the help or solutions to my situation. So i give it a little try here..
Good to know is that I'm new to jQuery.
What i would like to achieve
I have one single checkbox that, when checked, will unhide some div's. When you uncheck the checkbox the div's will hide again. This is sort of an "Option". This works fine with the piece of jQuery code i have now.
The problem is that when a user checks the checkbox and then loads another page (/page2) the checkbox is unchecked again. I would like to store the checkbox state for a session. So users don't have to check the checkbox again, and again after browsing to the next page (if they wish to use this option).[code]...

I have 2 textfields and I need to change a link href based on whatever is in those textfields.
The link has to be in this format:
The reason for this is I need to launch fancybox and as far as im aware this is the best way to call it.
So what im hoping is when I add type something in textfield1 this will be reflected in the url. And same for textfield2. I know this can be done easily if I submit the page but I dont want that.

Im using a jQuery script to show/hide a div based based on the selection made via a dropdown.
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
The problem im having is that the value used in the dropdown lists are price values eg 10.00
Consequently jQuery seems to interprit these as css notations, meaning the code doesnt work.

Site also employs CodeIgniter from original developer.
Code below sets up a table with a form and script in separate cells of the same row. Looks good and click on check box works ok, but script seems to only run when the page is initially loaded. Does not change variable 'c' and display the change. Am in a bind for this one. My developer is away for the holiday and CEO wants it done ASAP. code...
