I am new to jquery. I am trying to return a string array with two strings back to a jquery ajax call. On success, when I try to retrieve the values, my result is just a string "System.string[]". How do I retrieve the values that I returned from the server in my call back function for success.
"success: function(result, textStatus, XMLHttpRequest) {"
how to retrieve the values of "result"?
I have a very large form and have a couple of checkbox groups where multiple items can be selected. They are grouped as an array of checkboxes. When I post the checkbox groups, the PHP script receives duplicate values. If the group has 2 checkboxes, 4 values are posted. If it has 10 checkboxes, 20 values will be posted.
i.e:
I then submit everything to a PHP script via an Ajax call, then output the result to a div. (see below)
However, when my PHP script loops over the $_POST array, it seems that each checkbox array is duplicated, so my PHP array returns:
This happens with all my checkbox arrays, but not with an array of hidden fields for some reason.
I don't think this is a PHP problem, as it looped over everything correctly when submitting via a conventional POST. I checked the contents of $_POST, and it seems that the duplicates are being posted.
I am trying to use a $.post call in jQuery to check a user's credentials before submitting a form (so I can show errors without reloading the page), but I've run into a problem. I know why it is, because AJAX is not synchronous, but I just can't figure out how to do it.
In my code the script I'm making the call to returns "valid" or "invalid". If the return is "valid", I want to submit the form, if not, show an error message. Here is a simplified version:
$("#my_form").submit( function () {
some_value = "username"
$.post(script_location, {data : some_value}, function (data) {
response = data
[Code]...
This obviously does not work because code is executed quickly one after another and the variable "response" is not yet set when the execution gets to the if statement, since it is set sometime later, asynchronously.
I looked into using functions, callbacks, but nothing seems to work properly, I always run into the same issue. This is probably really simple, i just a complete dunce, please do let me know what is the standard way of doing this properly.
Lets assume the following object
Code:
var x = {
y: {
z: 10
}
} ;
Next, I need to retrieve the value '10', but the only thing I have is one string as a key For example (this doesn't work):
Code:
var str = '[y][z]' ; // or 'y.z'??
alert(x[str]) ; // should alert 10
Can this be done using a single string as input for x ?
UPDATE: a solution which comes close to what I was looking for is
Code:
var str = "x['y']['z']" ;
alert(eval(str));
I want to know if there is a way to return ajax call as html value and not plain text, ie all html formatting will be displayed.
My code:
<script src="jquery.js">
<script>
$(function()
{
[Code]....
String returned from webform4.aspx is html formatted but jquery displayed it as plain text. Is that anyway to display it as html string ?
To make cross domain calls when json is required (JSONP) is easy
Code:
$.ajax({
url:"testserver.php",
dataType: 'JSONP',
success:function(json){
[Code]....
I see the XML comming in as a string argument of 'myCallback', but ist never called. Also 'success' is never called!
I need to return a string of JS from my php file. In my ajax.php file these are the last lines ($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 have an object with a member function that changes something on the objects state. This works perfectly fine in the easy case. But when I use an $.ajax call within the function it doesn't work. Here is the example code and failing QUnit tests: [URL]

I am using ajax in my site and want to implement a friend request button. When a user clicks this button their userid and the userid of the friend thwey are requesting will go into a table called notifications in my mysql database. This works fine in regular html/php with javascript disabled but not when using javascript/ajax.
Here's my code which may clarify things:-
Code:
<script type="text/javascript">
function makeRequest(friendrequestloggedinuserid, friendrequestuserid)
{
if (window.XMLHttpRequest)
[Code]....
The above code works perfect if javascript is disabled and the button is clicked as the new row is inserted into the database however if javascript is enabled the alert shows inidicating the ajax file is working but the new row is not inserted. Is this something to do with the POST process between my javascript code and my ajax_processrequests.php file?
BTW $loggedinuserid and $userid are retrieved earlier on in my code but showing how they are retrieved is irrelevant to this because I know they are present at the point of the above code.
From WebForm1.aspx, I have successfully retrieved a string that is dynamically generated in WebForm2.aspx and spit out to a Literal control in a div. This is what I did.
//In WebForm1.aspx, I have:
$.post("WebForm2.aspx", { para1: "value1", para2: "value2" },
function(data) { $("#mydiv").html($("div#div1", data).html()) });
That's pretty simple and easy to understand for you jQuery gurus out there.
Now, I am trying to do the same thing within the single web form. That is, in WebForm1.aspx, I have this jQuery script to post to the same web form (i.e., WebForm1.aspx), but it is not working. Postback works OK, but I am not able to retrieve the dynamically generated string and spit it out to mydiv.
What's the jQuery way to do this? Any example? I searched, but I've only found examples which try to get static string values, which I know how to do.
i have a web service at this url http:[url]....i use hotel search file with HotelSearch method and method will retrieve xml file contains the matched data. the varialbe that i made post with it is named : HotelData
the data of the variable is a string file that contains an xml data like this
<HotelsParameters>
<CityID>388</CityID>
<UserName>admin</UserName>[code]....
the data in input filed is the previous xml file
date_arr[0]=new Option("January",31,1);
I got this value, how do i retrieve the last digit from it?
This is what is in the script now, it does display the first value and the text . But i want the last value in this OPTION,
document.writeln("<OPTION value=""+date_arr[x].value+"_"+date_arr[x].value+"">"+date_arr[x].text);
somebody got an idea on this one?
I have made a basic form, and I need to combine three values within my form, then create an md5 hash of this string.Then assign it to a hidden variable.My form is here...
Code:
<p>
<label for="firstname">First Name: </label>
<input id="firstname" type="text" name="firstname" /><br />[code]....
Or I have created a pastebin of it here, for easy reading: http://pastie.org/1171757.So I need to be able to combine the three values into a string, create a md5 of the string, then call the value of the string into a hidden value all before posting the form.
I load data to a div dynamically $.get(test.php, { cmd: cmd, id: id},function(data){$('#files '').html(data);});
The retrieveddatais in a table and looks like this
test.php
<table class="files_table">
<tr eID='1'>
<td> Content # 1</td>
[Code]....
i have a "on/off" toggle switch that hide and display a table row using javascript. On every click, this javascript will make use of AJAX to update the database on a table that stores the current state of the table row (whether to hide or display). Ok, basically it works on every page until i reach a page where only after "posting a form" will reach.
For this particular page, AJAx stop working. I do have a few more AJAX stuff in my website and it works on every page.
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.
Is it possible to break apart a string into characters, be it a word or a sentence, and store each individual character in an array?

I'm trying to use AJAX to load user's profile through a drop-down list on selected user. There are 3 seperate files:
1) view_info.php
2) selectuser.js
3) getuser.php
I tested and found that the value $q did pass from view_info -> selectuser.js -> getuser.php, and value changes correctly as i select different user from the drop-down list. Problem is, it simply can't fetch data from my database using the value $q. I tried debugging it for 3 hours already and is totally out of idea whats wrong with the script. i'm new to AJAX, this is my first script..

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.)
Anybody have a simple example of retrieving a page via ajax?
View 1 Replies View RelatedI have an ajax script that I would like to use to retrieve a password hint from a database.Both the ajax script and the php retrieval script are stored on the same domain (we'll call it domain1.com), but the ajax script runs on another domain (domain2.com).All the scripts are working fine, individually, but when I try to integrate them, I'm getting a ready state of 4, but an HTTP status of 0. I've traced the code flow and the retrieval script is being called by the ajax script OK and it's echoing all the right stuff, but it's just not getting back to calling ajax routine.
I've read that an ajax routine can only call a script that resides on the same domain that it runs on. Is this correct and, if so, does anyone know of a work around, because I really need to be able to store the ajax script on domain1 and run it on domain2?If not, then can anyone suggest why I'm getting an HTTP status of 0, when all the individual components are working fine?
I am doing a project now i going to use ajax to retrieve coordinate from the json in html and pin the coordinate onto a point on the map using javascript but the problem is i am only able to use one point on the map can tell me what to add in ? or how should i change it with? it will be nice if u can change the code from the below and show me how
