JQuery :: Ajax At Passing The Value Of Form?
Jul 7, 2009
I'm working on a generator that is supposed to do something after something is selected from forms. So here it goes: I got two select forms now. After I select the value from the first form the value of the form is passed to the second form and it then generates it's own values depending on the value it gain. I realized that you can do this without page refresh with JQuery and I thought that would be nice and I gave it a try but now I'm stuck and here is my problem:
I've problem at passing the right value from the first form. I only want the value of the option that is selected. All my values are coming from MySQL database. I've tried this: var str = $('#customer').val(); (customer being the id of my select tag of the form) but it just returns an empty array. I don't want to pass array in the first place. I just want to pass the value.
I've tried serialization too but iit passes the right value but it passes it so many times as I have options in my form.

So I'm making a "wiper blade application guide." I've got a form that starts out talking to my mysql database and grabs all of the makes. The user chooses a make. This calls a function that takes the value of the make and shoots it over to my database and returns all of the models of that make and populates the model dropdown box. Then they choose a model which does the same thing as the last one except it returns years. What is different is that my database has a startYear row and an endYear row which I am sticking together with a '-'. Then the user chooses a year which has to send make, model, and year (or at least model and year) over to the database query. I've managed to get it to send all of the values via an array but I can't figure out how to get them back on the php side.
Here is the code I've got.
index.php
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]">
<html xmlns="[URL]">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<link href="template.css" rel="stylesheet" type="text/css" />
<script language="javascript" type="text/javascript" src="jquery-1.4.2.min.js"></script>
<script type="text/javascript">
function get_models() {
var make = $("#make").val();
$.ajax({ url: "getModels.php", global: false, type: "GET", async: false, dataType: "html", data: "make="+make,
success: function (response) { .....
Here is a link to see it in action [URL].

Basically I want the field name to be a variable but it is taking it as a literal.When I print back the POST array with PHP I get:- Array ( [field_name] => Whatever I typed )So if the text field has a name of 'username' then I want the PHP to print back
Array ( [username] => Whatever I typed )
$(function(){//on DOM.load
$('.register-field').blur(function() {
var field_val = $(this).val();

I'm trying to pass parameters using the jquery's ajax function, but I end up with a "function undefined" error message when I try.
I had trouble finding simple examples of ajax passing parameters with jquery.

I have an image that is encoded as a base 64 string, and I'm having trouble passing that a WCF service using $.ajax(). I initally tried using JSON to pass the argument to the web service, but I kept getting 400 Bad Request errors for anything of reasonable length (if I just pass a test string in, it makes it through, of course). I've tried calling encodeURIComponent on the string before stringifying it, but that hasn't helped. I've also tried various content types ("application/json; charset=utf-8", as well as whatever the default is) and that hasn't made a difference either. Unfortunately, the request is being made through a mobile phone, so debugging options are few. Is there an upper limit to the size of the argument that I'm passing in this? The strings can be a few hundred kb at the low end up to maybe 1 or 2 mb at the high end.
Here is a snippet of the code I am using:
$.ajax({
type: "POST",
url: "http://www.myserver.com/MyService.svc/MyFunction",
cache: false,
[Code]....
No matter what the string consists of, it errors would with a 400 Bad Request error. No further information.

I have this code:
var dataString = $.toJSON(data);
$.post(url, {dataValues: dataString}, function(res){
$('#secretIFrame').attr('src', url);
$('#secretIFrame').html(res);
});
Problem is, I can't access dataValues at the server side once I assign this same URL to the iframe.Is there any other way to POST JSON value through form submission without ajax? or any other way out, I am trying to download file that is based on some parameters and isn't a direct download link.

<div>I have a bunch of ajax events that are fired one after an other to fill different spots on the page.Hence it's important that I know which dom element each on of the resulting data is supposed to belong to.</div> <div> </div><div>I was wondering if there is a way I can pass the id of each element into the call so that it gets returned automagically without any intervention by the server?</div><div> </div><div>In YUI I can pass any number of arguments to an axax call and these areguments are available as part of the response.</div>

I'm currently rewriting all my ajax calls to use the jquery method (much cleaner code! ) and have declared a default ajaxError function, shown below:
$(document).ajaxError(function(event, request, settings){
alert("There was an error while communicating with the server. URL: " + settings.url);
});
However, now I have a few ajax calls where I want to declare an error function in the ajax call. I was hoping that by declaring an error function in the ajax call, it would replace the default error call I have defined. But that does not appear to be the case, as I continue to first get my ajax function error call, then I also see the above code execute.
I tried calling event.stopImmediatePropagation() from within my ajax error function hoping that it would stop further events firing (ie: the default error event) but that didn't do anything except tell me in firefox that "event" was undefined.
I was hoping I wouldn't have to go through and define an error function to EVERY ajax call.

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 have a function that gets the value of a clicked on <span> like this:
function getSelectedValue(id) {
return $("#" + id).find("dt a span.value").html();
}
and sets the value of a second span like this:
$("#state").html("value: " + getSelectedValue("state"));
When I echo that second span, I get the selected value from the first span. But I need to get that value into a hidden html form field, so I can pass it along with the $_POST array. How do I do this?

I would like to have a main form (written in PHP) that has a "lookup" button next to a text field. When the user clicks "lookup", it should open a new window that lets them search (child.page1). When they enter a name or DOB into the search form, it submits the form through PHP (via POST), to a results page (child.page2). This displays all persons in the database which have a name or DOB == to the search term(s), with a checkbox next to each match. They click the checkbox (or alternenatively, a link), and return the checkbox value to the main window.
I have everything working right now, except that (child.page2) doesn't recognize the main window. If the data is entered on (child.page1), it works fine. I'm not very familiar with javascript.. is this even possible? I've considered using frames, to keep the parent-child relationship evident to the computer, but figured I'd check to see if there's an easier way.

I'm trying out uploadify to upload images & files. Got it all working fine and got it so that it inserts the filename as a hidden form element so I can grab the filename on post and insert into the database -
<script type="text/javascript">
$(document).ready(function() {
$('#file_upload').uploadify({
'buttonImg' : 'images/browseBtn.png',
[Code].....
But I want to rename the file in uploadify.php and pass the renamed value back to the form, so far, I can only get it sending back the original file name.

I am trying to pass an element's id to an ajax function so that I can update different areas by passing different ids to the same function, but I am not quite sure how to get it passed to where I want it to go.
Code:
function calGet(date,month,year,id,action) {
xmlHttp=GetXmlHttpObject();
if(xmlHttp==null) {//ajax won't work, redirect to a calendar php page to display the event with php
[code]....
In the function calGet I passed a parameter 'id'. I want to get this parameter down into the getElementById area in the stateChanged function and I've tried, many many ways, but I cannot figure it out.

I have designed a simple AJAX form which retrieves information from a MySQL database using PHP/MySQL/AJAX. Here is the code:
HTML Page:
[Code]....
My question is, once I retrieve the information I would like to pass the information (AuxBarcode, DeviceType) as hidden fields to an HTML form. How do I do that? The purpose of this being, we have a form where some information needs to be retrieved from a MySQL database and once retrieved it needs to be passed with the other elements of this form. I just need to understand how this works before we implement it on a full fledged script.
