Passing PHP Var From AJAX Handler
Feb 1, 2007
I'm having a problem with the returning a php variable from my ajax php handler.
I call the handler...
if(ajaxRequest.readyState == 4 || ajaxRequest.readyState == 0){
var ajaxDisplay = document.getElementById('ajaxDiv');
var refreshID = "";
var timeout = "<?=$timeout?>";
ajaxDisplay.innerHTML = ajaxRequest.responseText;
//Change Refresh Timeout Based on Remaining Song Length
refreshID = setTimeout("DoRefresh()", timeout);
DoRefresh() function is the ajax function. What am I doing wrong?

I have added an event listener to a LI item in the DOM:
liNode.addEventListener("mouseover", mouseOn, true);
The mouseOn function:
function mouseOn(e) {
// Test for IE or Firefox
var e = (!e)?window.event:e;
var yPos;
[Code]...
I would like to pass in another parameter to the mouseOn function in addition to the event that is passed in automatically. Is there a way to do this?

i'm new to ajax. simple request no problem - but it seems when I set
the response handler function, I can only pass the function name and
not give parameters, so I have a problem when starting e.g. 5 ajax
requests parallele. how to do that correctly? for one case, where I
used *different* resp. handlers, I solved the problem by global
variables - but now I have a loop of e.g. 20 calls to the *same*
r.handler and I don*t know how to tell the function *which* request of
the 20 to use. I expect the solution to be simple but how..

I'm trying to bind an event handler to a button in a page loaded via Ajax. This procedure should apply to every page I have to load via Ajax. I have tried two things: first, I declared the 'click' event handler for the button like this, and just did my ajax request. Here's the code:
$("#close_button").click(function(){
alert("This should popup");
});
$.ajax({
url: 'js/ajax/text.html',
[Code]...

What is the event handler for the Ajax.Autocompleter?
Is it onKeyUp or onChange?
I'd like to display the results using a button for example.

I have the following code:
$(document).ready(function(){
$('#link').click(function() {
alert('Clicked!');
$('#content').load('dialogs/load/content', function() {});
});
});
The link is a normal link that is not dynamically created. The alert works. I know the problem is not the Ajax call because this works just fine:
$(document).ready(function(){
$('#content').load('dialogs/load/content', function() {});
$('#link').click(function() {
[Code]....
It only breaks when located inside the click handler. It does not return response headers or a response. Is there something about event handlers and ajax that I'm missing?

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.

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].

Note: answers along the lines of 'use jquery' or 'use (insert wellknown framework)' is not helpful.Frameworks such as jquery includes alot of extra code which is not nessary at all for what I am doing. 'But, you can include one from Google', yes that may be the case, but I prefer to keep to my own code. With that in mind, lets proceed to the problem.
I have an ajax call which doesn't pass POST vars through on IE7/IE8, but only on odd occasions. It appears to be extremely random and the majority of the time it does work. I am had a look at jquery and cannot see much difference in the way it works compared to this custom one.

I have a webpage (Perl) that allows a user to select one of two buttons that represent :
<button id = "1" onclick="loadXMLDoc('mysqlinsert.pl')">Choose $name1</button>
<button id = "2" onclick="loadXMLDoc('mysqlinsert.pl')">Choose $name2</button>
Based on the button they choose, I need to pass a variable (declared in Perl) to another Perl page that is responsible for updating/inserting in a MySql Database.
As you can probably tell, I'm new to this. But I'm not sure how the variable ($name1) can be used in Perl to the loadXMLDoc, and then get passed using the 'POST' technique to mysqlinsert.pl??
function loadXMLDoc(url)
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari

Over in this thread, someone suggested a solution to an issue I was having when attempting to send multiple values per select box to a php file. You can review my original post here for reference:
[URL]
The problem is, when I change my form names to be arrays (i.e. age[] vs. age), it broke my Ajax script. I copied the original script from w3schools, and I don't really know much about javascript/Ajax to know what it is that I need to do to fix this.
Here is my Ajax script:
Code:
<script type="text/javascript">
function showResult(name,age,gender,ethnicity,facility)
{
if (name=="" && age=="" && gender=="" && ethnicity=="" && facility=="")
[Code]....
Now, when I leave my field names without the [], the script works MAHvalously. However, as soon as I add in the [] to the field names, and also update the vars to be age[].value instead of age.value, etc, it breaks.

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 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.
