JQuery :: Method To Update One Form Element With Value From Another?
Jul 27, 2009
I need to make a change to a web page that has lots of JQuery things in it, it appears. Not knowing anything about the actual use of JQuery, however, while I will start looking at the doc, can someone
help me with what to look for in a 4000+ line file to find out where the value is being set for the hidden field. I have been unable to identify this. There appears to be no onChange or onSubmit JavaScript call. I have been given this file with the need to figure this out right away, with a very tight timeline to make many changes, so this one item can't take the time required to start learning the whole of JQuery before I can make a change.

I'm using Javascript to create some dynamic content on my website. Basically it's looping through some values and updating an input field with the values.
What I'm wondering is, do I have to do this using a form and an input field? Is there a way I can get Javascript to update the content inside a DIV for example?

Is the form below a valid method of changing the id of an XHTML element, specifically the one actually being referenced? It does not seem to work for me.
document.getElementById("Original_Name").setAttribute("id", "New_name");

I have two input fields and I want the second updated every time I change a value in the first. I wrote this function but it doesn't work until the first element lost focus (for example I clic anywhere or press
TAB button)
$('#order').change(function(){
$('#total_buyed').val($(this).val() * 2.75);
});

Let's say you have a :<a href="#" onclick='DoSomething(this);'>asd</a>I want to get the onclick text in a variable - something likevar onclick = $('a').attr('onclick');The problem is that the onclick variable now is a function and if Itry to execute , this wil be the document instead of the link .How can I get only the text, so I can later reattach it to the link ?

I've done a fair bit of development in php, html and css, but none whatsoever in javascript so far.
I've found myself looking to jQuery as a potential solution to an interesting problem that I'd like to solve: I have a basic CMS that clients can use to manage the rental of items (caravan pitches to backhoes). The site administrator gets to enter the details of their products, prices and so forth, and then visitors to their site can see the availability of their products on a dynamically generated calendar - and book them online.
Part of the CMS allows the creation of 'seasons' - periods of the year in which a product's rental price changes - for special offers, etc. Different seasons are shown on the calendar using different css markup that the admin can change in the 'create/edit season' form.
Clearly, I can't expect Joe Siteadmin to type correct CSS and, ideally, I'd like to avoid limiting him to a swatch of pre-generated choices. So, having been seduced by the sexiness of the jQuery UI calendar plugin, I was thinking that it ought to be fairly easy to provide a jQuery color picker of some sort on the 'create/edit season' form, maybe with some radio buttons to dynamically link the picker to change background, text and border color - and update the relevant css rules for the colors chosen, on the fly, in the relevant input field on the form.

I was making mysearchfieldI though jQuer may help update one dropdown box when a value in one box is updated.
So, my search goes like this, Search for Pet [PetDropDown], Search for Breed [BreedDropDown], Search Location [Text feild] and Search Price [Text Feild].
So in this system i want the [DropDown] box to automatically update it self, with no reloading, thats where jQuery comes in (im guessing) with a list of Breed that link with the Pets DropDown. So if the user picks Dog, then the Breed Dropdown will show Breeds that areassociatedwith Dogs, such as Collie, Jack Russell or Staffordshire Bull Terrier. If a Pet isn't selected then nothing will show.
The information come from the data and a phpstatementfor the Breed DropDown would be as such: $sql = "SELECT id, title, value, type, cat FROM site_cats WHERE type = '[PetDropDown]' "; of course it wont be [PetDownDown] but as a $value such as $petType or $pet.

I have an idea for a little script.....I'm just stuck on one little part: When a user changes the value in a input or textarea box, I want it to change the value of a certain hidden input tag too.
Here's what I have so far:
function getNewValue(inputhidden, textinput) {
var data = document.getElementById(inputhidden);
var text = document.getElementById(textinput);
data.value = text.value;

I'm having some problems understanding the append() function. What I'd like to do is select an element using it's ID and add a row to the table with a HTML form element. The table is dynamically generated using a Django template ( form.as_table() ) so I'm not able to alter the original HTML markup too much.
If I had a table like this...

I have created a form with malsup's Form Plugin wherein it submits on change of the inputs. I have set up my jQuery script to index drop down menus and visible inputs, and uses that index to determine whether keydown of tab should move focus to the next element or the first element, and likewise with shift+tab keydown. However, instead of moving focus to the first element from the last element on tab keydown like I would like it to, it moves focus to the second element. How can I change it to cycle focus to the actual first and last elements? Here is a live link to my form: [URL]. Here is my script:
$(document).ready(function() {
var options = {
target: '#c_main',
success: setFocus

I have very basic javascript skills, just started looking into jQuery and jQueryTools to enhance my websites. I have been coding PHP for about 1.5 years.I have a php form with which users can update their purchase order before making a final confirmation and payment.
Thought it would be nice if, instead of using php for redirecting to a success/fail message in a separate php file and redirecting again back to the form with a 3 second delay, I could get a jQuery script to pop up with a success/fail message, so avoiding all the clumsy php redirecting and page refreshing.I've searched for plugins, but they all act on event listeners attached to a submit button or other clickable html element.Ive searched the net for ages and can't find an easily understood explanation and complete example, where a jQuery pop up notification is displayed in response to a php script executing a db update.

For instance, Box A has a blank entry and I enter in 5. Box B I enter in 6
so in Box C it should automatically give me 11 (if the code I put in is to
add box A and B). Then in Box D I put in 3 (say to subtract from A and B
combined) so then Box C adjusts to give me 8.
Don't worry about the math as that's all taken care of it, I just need to be
able to know how to update on the fly like this.

I'm having a problem where the serialize method isn't serializing form elements that are added to the DOM after the page load. Specifically, when the user clicks on a button some elements are displayed in a dialog that are generated from my server and returned via AJAX. I'm converting from Prototype and didn't run into this problem.

I'm working on a script that will produce multiple dynamic forms based on the results of an ajax request. The ajax request does a db query that will return 0 to x number of rows. For each row, a new serialized form is created. Since the forms do not exist at page load, I'm having problems getting the value of the form elements so that I can run other functions on them (update inputs and selects). I've stripped down everything so that I can show a basic example. In the example, how would I get the value of "#orderID"? The body contains a div (previousList) that has a list of items that when clicked will trigger the ajax query. It also has a div (line details) that will hold all of the forms that are generated.
<div id="lineDetails">
check it out </div>
<div id="previousFrm" class="ui-widget-header ui-state-highlight ui-corner-all">
<h3>Previous Returns/Cancels</h3>
<div id="previousList">
<ul class="previous" id="returnList">
<li id="1000997" class="names">1000997: 101853</li>
<li id="1000995" class="names">1000995: 101853</li> .....
But callingconsole.log("order line value is " + $("#orderID").val());
results in 'undefined'.

I have a pageA containing a form the user my fill in partially. All data is stored into cookies. He follows a link to pageB that contains some of pageA.form inputs. If he adds or change form data cookies are instantly updated. What I need is if the user goes back (back browser button) to pageA, the form here is updated from updated cookies. Only Firefox 3 does the job without extra code. Ive tried all sort of things I found on the web with Opera 10, Chrome and Safari 3.

I'm making a survey where every question has a numeric value assigned to it, and as the user clicks on a checkmark button to approve (or uncheck to disapprove) the values add or subtract to give a total at the bottom of the page.
Basically, it's a spreadsheet but with fixed values for each row instead of being able to type them in.
I can do this easily with php, but only if the user clicks the submit button. I was hoping to find a way to do this real-time.
I'm not looking for someone to do this for me, but can someone point me in the right direction of a tutorial or something that is similar so I can build this into my program?
