Environment is PHP - MYSQL When the user changes the value of a select drop-down, I want to use Ajax and query one table of my database, retrieve three pieces of data, and place the data in three separate text fields in my form. Is there a simple tutorial out there that explains this?
I get the general concept of the separate php file for the query, but I'm pretty much lost.
so, the pseudo code: - on change of input contents, check to see if two input fields are set - if set, update a third field with "loading..." text and a loading gif - use ajax to send data to a url, and get a calculated json response - update the third field with the calculated response
I know I'm getting the correct response, according to firebug: {"pace":"10:00"}
the code:
$('#run_distance').change(function() {
if ($(this).val() != '' && $('#run_time').val() != '')
{
$('#run_pace').val('Calculating Pace…');
[Code].....
how to update the #run_pace input field with the json response.
I'm creating a page that calculates a number depending on what value is inputted into a text field. I need to create some javascript that updates this new calculated value and outputs it next to the input field. Anytime the user changes the number, it recalculates the value. My calculation is currently being produced by PHP, however if I need to, I can create javascript as well to recalculate these numbers.
View 4 Replies View Relatedwhen the user types a FIRST NAME into the first name textbox this should update the paxname with the value and a space.when the user types a LAST NAME into the last name textbox this should update the paxname with the value therefore at the end of the process the paxname will have the full name of the person in order with spaces in between. also i would like the first name and last name values to be changed to proper case ie John Smith once placed into paxname the update process does not have to be instantaneous, it can perhaps update the paxname textbox when the focus is gone from the field in question, dont mind how it works as long as it updates.
View 6 Replies View RelatedHave the following code which (resides in a dialog box) and serves as an event listener for check boxes. Am able to populate / de-populate text field with values from check boxby checking or unchecking the individual check boxes:
// Event listener which picks individual contacts// and populates input field.
$('#emailCheckListId_ul input:checkbox').change(function() {
// Declare array
var emails = [];
[Code].....
However, when I use try to use theJQuery Tagifyplug-in it only creates one "tagified dynamic label" inside the text field but doesn't create another label when I click on an additional check box. Also, when I uncheck the original checkbox, itdoesn't remove the original label.
Here's my code using the JQuery tagify plug-in (all I did was keep everything the same as above but called the tagify functionon the text field):
// Add / Remove array from text fieldtextField.value = emails;
// Decorate with dynamic label
$(textField).tagify(emails);
I get this JavaScript error in the browser:
jquery.tagify.js: 'options' is undefined, line 71
In the source code this line reads:
_setOption: function( key, value ) { options.key = value;
},
Its stating that options.key is undefined...
To view the jquery.tagify.js complete source, clickhere.
Is there a way I can create an "else" for example:
// Iterate through each array and put email addresses into array$('#emailCheckListId_ul input:checkbox:checked').each(function(){
// do something
});

I have a form that has a pretty complicated combo box - a user starts typing text, it queries a database for matches, and displays the results to the user. The user can then select the match they desire and it has a value id, which I am currently sending to a hidden field in the form. So, for example: user starts typing in a movie name, Seven - it returns Seven and user selects it. The form submits the id of the movie seven (say 12) to a hidden field.
Where I am stumped: Once a user selects a movie title, I have another drop down select box that is to display the available formats of the movie by querying my database based on the product id (12) and returning the available formats in the list:
DVD
BLUERAY
VHS
I am pretty good at programming, but I cannot figure this out - how to make the select box fire and return results once the value for the textbox has been captured.
A while back, I an working on dynamic form creation. I wanted a user to be able to enter into a text field how many designs he or she would like, then, based on that number, be provided with a pair of text boxes that asked 1) name of design 2) quantity of that particular design. I received this cool way of doing it by user thraddash:
<head>
<script type="text/javascript">
function BuildFormFields($amount){
var
$container = document.getElementById('FormFields'),
$item, $field, $i;
$container.innerHTML = '';
for ($i = 0; $i < $amount; $i++) {
$item = document.createElement('div');
$item.style.margin = '3px';
$field = document.createElement('span');
$field.innerHTML = 'Name of Design';
$field.style.marginRight = '10px';
$item.appendChild($field); .....
As a followup, I wonder how to control in a table where each of these text boxes will appear.
I want to create a javascript function where I have a dropdown list and onChage I want to update a txt field with the current date in the dd/mm/yyyy format.

i want to show alert here if that input field value exist.but problem is that response text has other data as well so how i differentiate to alert .
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 looked all over the Internet for the last few hours and the main articles I can find are using JQuery or Prototype to handle validation. However, I am trying to work on a series of forms (They won't work with tabs due to their nature) which depend on other items in a database.So, what I want to do is if someone is inserting a record in Form 1 to input into Table 1 which has an ID from Table 2, it will pop up a new form (shadowing out Form 1, sort of like LightBox does) to create the new record into Table 2. Once this record is inserted successfully, it will return control to Form 1.I plan on making an OnKeyUp activate this script when someone clicks on the textfield to add a new category. I understand what I have posted may be a little confusing, but I basically just need to be pointed in the right direction with a couple of tutorials to follow for how to use AJAX to show forms.
View 2 Replies View RelatedI need to perform an Ajax request as someone is typing into a text field. But I don't want to trigger a request on every key press.

I have a text field (field1) already displayed on the HTML page. However, there's a link where you can add additional text fields to the page as well. When the link is clicked, the second text field is added successfully (field2), and when the link is clicked again, the third text field (field3) is added successfully. However, the third field does not add itself to the page, and the text for anything greater than a third field also isn't displayed after. This obviously means that my "fields" variable is not working right
<script language="javascript">
fields = 1;
function addMore() {
if (fields = 1) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field2' size='25' /> <span>Field 2.</span>";

I'm trying to create a webpage where users can click on a dynamically generated set of questions:
<?php do { ?>
<p><?php echo $row_rsQuestions['question_text']; ?><?php echo $row_rsQuestions['question_type']; ?></p>
<?php } while ($row_rsQuestions = mysql_fetch_assoc($rsQuestions)); ?>
and by clicking on a particular question, there will be an update for their particular listing of personal questions in a MySql database. I know how to create the database update part, but I think that I would need to javascript to:
1) tell my page that it's time to update (i.e. add a particular question as soon as they click it)
2) pass along the correct variable to the database update portion of the page.
I'm trying to update a sql table from mi php Ajax web page, which stores dynamically a table into the page by table.appendChild(row) , so that the user can verify the information he is inserting before the actual database update.
How do I do this with ajax?
I'm trying to update my page with either a yes or a no, I'm using Ajax for the request to the server. The request works perfectly, however when I try to update the DOM with the server response using $(this).text(response.waiting); and $(this).html(response.waiting);.
I've tried alert(response.waiting); and returns a valid response. So, the problem probably stems from the DOM.
$("#data a.waiting").each(function(i){
$(this).click(function() {
$(this).html('<img src="../img/loading.gif" id="loadwait" alt="Loading..." />').fadeIn("slow");
$.ajax({
type: "POST",
url: "waiting/ajax/",
data: "id=" + $(this).attr("name"),
dataType: "json",
success: function(response) {
$("#loadwait").hide();
$(this).show();
$(this).html(response.waiting);
}
});
});
});
I have 4 HTML selects, ID'ed as "genres", "artists", "albums" and "songs". When you click on "genres", "artists" or "albums" the other selects should be updated through an AJAX call that does an sql query and respond back with JSON data. Sounds simple enough... but I can't get it to work. After just reloading the page, I can select a genre, and all other fields are updated, but then the other selects don't work any more.... as if jquery doesn't fire anymore when clicking on them.
This is my code
function updateSongs(JSON_data){
var song_options = '';
for (var i = 0; i < JSON_data.length; i++) {

I'm trying to "combine" PHP and Javascript to a possible workaround.
I have a test form with two objects;
- a text field
- a drop down box; the items are stored in a MySQL table
In PHP I can adjust the items of the drop down box by submitting the form (button) and querying the results out of the database.
In Javascript I can do this without a button to submit the form.
But I have to include all possible values (>1000) for the items in the script...
Is there I way to combine the two (on leaving the text field, the items in the drop down box should being build from a MySQL database using the value of the text field...)
Can anyone help me out here?
All I need to do is; on the click of a button, import the numerical
data in an html form (only one field) to a cell in a spreadsheet. Both
spreadsheet and the html file reside on the same server but there are
no dynamic capabilities. All I can use is html pages + javascript (or
anything else which do not require any special programs to be installed
on the server). Is this at all possible?
I am having a couple problems with what I am guessing is sequencing. I have several different events that perform a task and then refresh a portion of the screen using this code snippet: function RefreshComments(sID)
[Code]...
So this comes down to finding away to fire the javascript function only after the JQuery function has finished updating the HTML property of the DIV tag. I'm having a similar problem with a .post() command, and I expect whatever the solution is to this problem can be used to resolve the other as well.
I've created some jQuery which remove many tr rows from my table and inserts new via AJAX. This indicate that the page is scrolling because first the table increase after elements is removed and afterwards it grows when the new content is inserted. Is there a way to let jQuery update this table without doing so? Eg. by first refreshing the DOM after I finish my manipulation. Here is a bit of my code:
$j(".bookingViewRow").each(function() {
$j(this).remove();
});
$j.get('cajax.php', {}, function(html) {
$j("#bookingView").append(html);
});
I am using jquery ajax to load a comment element when editing a participant. After submitting a comment the whole element is dynamically reloaded, including the script part. Which looks like this:

This works for the first time, but when I try to submit again, the script block is missing and the ajax doesn't work anymore. I have read that with "dataType:"html"" the script part is evaluated on load, but I don't want that, or do I? How can I disable that? With "text" or "script" it doesn't get better...
