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?
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(){
$.ajax({
type: "POST",
url: ""+CI_ROOT+"index.php/admin/check_if_username",
data: ({username: username.val()}),
async: false,
dataType: "json",
success: function(data){
returnUsernameBool(username, data);
}});
}function returnUsernameBool(o, data){
if(data.bool == true){
o.addClass('ui-state-error');
updateTips("Your username must be unique");
alert('false'); //this works
return false; //still can't return bool
}else{
alert('true'); //this works
return true; //still can't return bool
}}
bValid = bValid && checkIfUsername(username);
alert(bValid); //still gives undefined
I am calling an AJAX function from a certain method, but for any reason it does not return the result.
The JSON object is "Records". The URL is build within another method and properly passed (as I can see in Firebug)[code]...
I need to return a string of JS from my php file. In my ajax.php file these are the last lines ($js is a string of js generated dynamically, it works as its calling a function I'm using at the load of the page): $js = getData($day,$the_vote);

I am having a problem of calling the user defined JS function after I make the AJAX call. Basically, I created couple radio buttons on the main html page. When the user clicks on one of the radio button, it will trigger the AJAX call and return another html file in the "div" content that I set in the main html page. The other html file contains a user defined JS function (e.g. "updateContent()") which use the onclick event handler to call the function. When I'm running the app, and click on the button. I had seen the firebug was complaining the "updateContent() is not defined" error. The function itself works fine and must be defined properly.
Here is the code in the main.html page:

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 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've got an ajax call that runs a password verification. The username/password work fine but I can't get the php to send data to to the AJAX, instead it just echoe's the result in an alert box code...
View 2 Replies View RelatedBased 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]....
The general framework is a simple user login function. The user name is selected and a password entered as usual. The function grabs the element values and passes them to a php page that queries the database. An AJAX call returns the password to the function and then I want the innerHTML to be a choice of two web pages, depending on success or failure of validation. There are existing AJAX functions available on the internet but they are overly complicated for what I think should be a simple, quick to load function.
Where I am stuck is that the standard procedure to make an AJAX call is the browser window event. How do you make the call from within the function? I have tried creating two new variables, "success" and "again" to replace xmlhttp, but still stumble on the event to assign a value. I left the blank password protection (if statement) with that variable to demonstrate what I mean.
I've put in my code below, which is in development and successfully alters the innerHTML text depending on user input but I can't figure out how to insert the relevant php page. I have '// out' the testing bits, but left them for info. (I have tried full 'scripting' as the innerHTML, but it's messy.)
Im just getting started with Jquery, and now i have a little problem. I tried to search several solutions but none of them seems to work.

Relatively new to jQuery but have a problem with getting data to display.Using a webform with 2 forms. User slects and inputs data into the first form, clicks a button then using jQuery .ajax submits the serialized data to a php script. The script processes the input into multiple paragraphs of text which is based on the input from the first form.The data is returned to the webpage and displayed in a text area (of the 2nd form) where the user can edit it to fine tune the wording. The 2 forms are displayed in different tabs so it is easy to move back and forward between the 2 forms.
The problem occurs when the user goes back to the first form and enters or selects different text and then click the submit button to generate a whole new text for insertion into the textarea on the second form. For certain fields the modified text is displayed.However if the whole of the text in the textarea is deleted, then the user clicks the submit button to re-generate the text content area then nothing at all is ever interted into the textarea. If have user alert to check that data is returned from the php handler and this text is correct. BUT when I click on the tab to see the textarea (id is "draftrec") there is no text inserted. The relevant function is below and the line that should insert the text into the textarea is:
$("textarea#draftrec").html(data).show();
//------------------------------------------------------
$("form#form1").submit(function(e){

Is it possible to return Query results from a jquery $.ajax POST call?It seems as though it will only return one value. What am I missing? [code]
View 1 Replies View RelatedI 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?
I wrote the following code with Dreamweaver:
If I run it in Dreamweaver It works and the alert success is raised, but If I run this code into Safari or Chrome the Error alert is always raised.
My goal is to get some HTML content including some UI widgets and other stuff via an ajax call. To clarify my goal and the strange behavior, I attached some HTML files, that you can run for yourself. Open the index.html will show you some UI widgets, which are pulled from the ajax.html via ajax. When you scroll to the bottom you can see the same content inserted a second time. But this time, the widgets are not "rendered". It looks if the "button()" calls etc. are not executed.
The only difference is the way I insert the result of the ajax call. The first time I insert the hole content received by the ajax call, the second time I only insert the content of a special div. The goal in this is to get various chunks of content with one ajax request and replace "div#one" and "div#two" with different parts of my site. Which is not working. Is it generally okay to receive html content which has some script parts to be executed via ajax and what is wrong with my second approach?

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?
