AJAX :: Get PHP Return Status Using JQuery
Mar 26, 2010
I am writing a contact form using jQuery AJAX POST and PHP. The form works well and sends the email. What I want to know is how to get the return values for error and success on the same page where the contact form is rather than having the message go to another page. I created a DIV called statusBox, and I would like all the messages printed there. Below is the fragment from the jQuery side. What do I need to do on the PHP side to get the values back?

I am trying to write a tool (say [URL])The tool contains a list of https urls (say [URL]) given as a hyperlinks (say abc) on clicking the url the http status code of the https page should be displayed in the same page.. Is this possible? I am currently using the following code snippet..
function sendRequest(url){
var client = new XMLHttpRequest();
client.onreadystatechange = function(){
if (this.readyState == 4)
alert(client.status);
} client.open("GET", url, true);
client.send(null);
}
This seems to be working if the url given is http url but I have to get status for https url for a non-secure (http) url.

I'm attempting to use AJAX to retrieve information from an XML file and apply it to my HTML page. The code looks to be fine but for some reason my

requestObj.status == 200
never reaches 200. In Safari when i debug it says this status is no longer valid.and in IE it tell me the
Code:
requestObj.open() has been denied.
HTML document
Code:
<body>
<div id="xmldata"></div>
<script type="text/javascript">
window.onload = readyAJAX;

I have researched this error/bug/mistake thoroughly with no success. I must be the only one experiencing it. Also, this takes place on every site I develop with jQuery ajax. It happens regardless of whether I use .get, .post, .ajax etc. Problem: The result returned to my ajax function always has a zero (0) appended to it.

I'm trying to make a call to .ajax and as a result set a value in a hash (for another call to jquery-ui)
I get the data coming back fine, could put in in a text field in html but not the hash where I want it.
Here below are the parts of my code that I'm using
//setting up datepicker
$(courseStartDateHtmlId).datepicker({
.....
defaultDate : ($(courseStartDateHtmlId).val() != "") ?
[Code].....
I thought that the value of startDate would end up as the defaultDate param for datepicker. No luck. Only an obscure little message in firebug console: "missing: before statement"

I'm currently using the dialog functionality (modal form) from UI library to submit data to the database. All the validation checks have been running ok until one of the validation checks requires a ajax call to check if a username exist in the database. I'm fairly new to both javascript and jquery so this could be a fairly basic blunder. Initially, i thought it was an synchronicity problem, but I changed the $.ajax async option to true but still no joy, so maybe it something to do with scope etc?
Here's the code:
function checkIfUsername(){
$.ajax({
type: "POST",
url: ""+CI_ROOT+"index.php/admin/check_if_username",
data: ({username: username.val()}),
async: false,
dataType: "json",
success: function(data){
returnUsernameBool(username, data);
}});
}function returnUsernameBool(o, data){
if(data.bool == true){
o.addClass('ui-state-error');
updateTips("Your username must be unique");
alert('false'); //this works
return false; //still can't return bool
}else{
alert('true'); //this works
return true; //still can't return bool
}}
bValid = bValid && checkIfUsername(username);
alert(bValid); //still gives undefined

Is it possible to get a return value from a page call within an ajax call? For example,
$("#new_request").click(function(e){
$.ajax({
url:"_insert_new_request.php",
type:"GET",
[Code]....
Here I make an ajax call from a click on a div. I then call "_insert_new_request.php" page, with a param of "partner_id_link".
Can I return a value from the "_insert_new_request.php"? and how?

Based on a simple AJAX way, I can run a php process and return the result by this line Code: xmlhttp.open("GET","getuser.php?q="+str,true); There is another method using jQuery (e.g. in [URL]). But here, it shows a predefined message in these lines
Code:
//hide the form
$('.form').fadeOut('slow');
//show the success message
$('.done').fadeIn('slow'
How I can return the output of the php script within AJAX instead of this message?

[code]....I have 2 DropDownList, like Master-Slave.This is my Default.aspx:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
[code]....
but there is nothing to append. Also I see the response in firebug windows as following(when I Select G2 from Master ddl):
[{"Value":"G2s1","Text":"SV1"},{"Value":"G2s2","Text":"SV2"}]
And for more specific view the following pic is the JSON tab in firebug windows when I select G3 in Master ddl:I change my success method of script with this new one for test:
function SuccessHandler2(data) {
$('select#Slaveddl').empty();
$.each(data, function (i, slaveValue) {
[code]....
So I think there is a problem with manipulate of return value (data).Also I try this one and just the first alert appear, apparently the (data.d) is null or unknown object:
function SuccessHandler4(data) {
var selection = $('select#Slaveddl');
$(selection).children().remove();
[code]....

I have been working on favorite blog on my site. I have done this with radio button. But I want to do this with AJAX. Like it has on flikrs.com. If you click on favorite tag it will show the bright star or something that indicates its your favorite photo. Or if you again click on that star it ll become dull, like its no more of your favorite photo.

I'm making a script that requires cross-domain scripting to get the statuscode of other files. I'm currently using a small PHP script to relay the files from the remote server onto mine. If I want to get the files directly using AJAX, it is not allowed for obvious reasons. I don't want the actual files, I only want to get the status code of that file, and it is going to be either a 404 or a 301. I would've assumed that as the AJAX call is never attempted, the statusCode will be 0, and this is what the actual call variable returns.
However, in Firebug it shows the statuscode next to the request (404 or 301), even if, the call has never been made. Why is the statuscode appearing in Firebug but not in the statuscode variable?

if (xmlhttp.readyState==4 && xmlhttp.status == 200) {

I am currently trying to get an action on the click of a link, and not make it follow the link, just carry everything out in jQuery. Now, if the AJAX request isn't there, it will work as supposed too, but with the AJAX request, it will follow the link, not taking any notice for the return false.

I am attempting to use the return value from a nested ajax function as the value for a variable in its parent. However, despite being able to successfully assign the variable within the nested function, it reverts back to its original value after the child function has terminated. Below is the code:

I'm implementing theStar Ratingplugin. Star rating is called like this:
$(function(){
$('.stars').rating({
callback: function(value, link){
$.ajax({
[Code]....
After a star is clicked the form is submitted and processed. "rate.php" returns an integer from 1 to 5 with the new average rating. So far so good, but I'd like to update the Star radios with the new value and disable them after the form has been processed.
It seemed easy enough:
$('.stars').rating('select', data);
$('.stars').rating('disable');

So I'm currently working on a ASP.NET Webforms site and I've run in to a small problem. On my .cs file I have the following Webmethod
[WebMethod]
public static string IsJobEditable(int jobid){
try{
string isEditable = "false";
JobsBLL jbl = new JobsBLL();
int jobStatusId = jbl.GetJobStatusId(jobid);
//If the jobs is either waiting or being edited it is
okay to edit it
if(jobStatusId ==
Convert.ToInt32(ConstantsUtil.JobStatus.Waiting) || jobStatusId ==
Convert.ToInt32(ConstantsUtil.JobStatus.Edit)){
isEditable = "true";
}return isEditable;
}catch (Exception ex){
throw ex;
}}
This function in this case will ALWAYS return TRUE as a string. On Aspx page I have the following
$(function () {
$.ajax({
type: "POST",
url: "Coordination.aspx/IsJobEditable",
data: "{jobid:" + jobid + "}",
contentType: "application/json; charset=utf-8",
dataType: "text",
success: function (result) {
alert(result);
//This is written out in the alert {"d":"true"}
I want this in a variable as a string so I can do a check on it before I do some other actions. The format is not a String so I cannot split on it to retrieve the "true" part.
},
error: function (err, result) { alert(err); }
});});
As you can see in the comments the value I get back in the Callback method is in to me a weird format. The type is unknown and I need this value to be able to proceed with my entire method surrounding the small portion of the Javascript. Where to access the result variable / data as a var or anything else that will let me put it into a var (as a string).

im trying to learn how jquery ajax function works by validating some form after submit is clicked.
[Code]....
the alert didnt pop until i added the registration_ok = false; right before, so im assuming it has something to do with the ajax functions's scope.... why does the ajax function not affect the registration_ok variable outside the function? and how should i solve this problem? any better way of doing it?

Anyone know how to return true or false to an event handler based upon the results that come back from a Prototype Ajax.Request call?
I have a link with an onclick handler that calls a function getLoggedIn(), which looks like the following:
function getLoggedIn(type) {
ajax = new Ajax.Request(
'includes/checkloggedin.php',
{
method: 'get',
parameters:'&type='+type,
onComplete: checkLoginResult
});
}
As any analysis of request.responseText occurs in checkLoginResult(), not getLoggedIn(), how can I pass an Ajax-response-determined return value back to the event handler?

I'm new to ajax and coded a script that returns the result of a php file. It is fine if it is just text, but if it has html included it prints out the tags instead of treating it like html. How do you treat it as html? I've heard of innerHTML but was told it isn't viewed as standard compliant and some browsers don't even support it.
