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 RepliesSo 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).
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){

I am writing a small data entry screen that will post the form data to a page and return a message. But i cannot get the Success or Error functions working properly.
Here's the code where strData is the posted querystring of:
I'm not sure whether it should be in a form and using the onsubmit or click of a button.
Before 1.4, it is possible to return an unique ID with jQuery.data(elem), now seems does not work.
[url]
The new api must need a key, what is the key then?
I just want an unique ID by inputing an element, why I need such a key?
When I submit a post request in jquery i.e code...
How can I parse the returned data to get a specific element if the returned data is just an html page?
I found this post: [URL] It explains exactly what I want to do. The person who had the problem seemed to have sorted it out but as my knowledge is not to great I am not to sure what he is getting at. I tried various things but to no avail. All I want to do is return data to a calling javascript using type get and datatype jsonp. If I simply Response.Write "[(""id"": ""123""}]" then nothing happens. So whatever the thread I revered to above is doing it seems to be going in the right direction.

<?php
//Get the data from system and return in EU format
function ShowDate() {
$Date = date("d"."/"."m"."/"."Y");
return $Date;
}
//Get the time from system
function ShowTime() {

Now I have two input box

Type the date:<input name="txtdate" type="text" class="input" id="txtdate" title="e.g dd/mm/yyyy" value="<?php echo ShowDate(); ?>" size="9" maxlength="10">

Type the time:<input name="txttime" type="text" id="txttime" value="<?php echo ShowTime(); ?>" size="5" maxlength="5">

So.... the important is the user can interactive with the date. If I change the date or time all this values will be change as well. Someone knows how can I do this? The field txtdate I will get from a calendar plugin (javascript) that I already put in my code.
I am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?
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 stumbled on this problem while testing StatusNet for our next release; we use jquery.form's .ajaxForm() to do various AJAX form submissions, including the primary message-sending form which includes a file upload control.
We've not seen problems before, but since upgrading from an old Form plugin version 2.17 to 2.49 a couple months ago, I've noticed our development branch no longer works properly in Opera: the actual submission goes fine, but we're unable to access the XML return data (which usually contains HTML fragments to put back into the UI).
I have a test case which demonstrates this at [URL] (source of the main page & submit handler are included there), using current jQuery 1.4.4 and jquery.form 2.52.
Under Firefox 4.0b10 and other browsers, the forms submit correctly, and we can read nodes and text out of the returned XML just fine.
But on Opera 11.00 and 10.63, the submission goes through but we get back an HTML document containing only "<head></head><body></body>". On Opera 9.63, it also includes the text "Blank page."
I tried to trace this down in jquery.form's history, and the trouble seems to have started around 2.39 with a commit ironically titled "iframe load fix (mostly for Opera)", which changes the event handling for forms submitted via iframe: from that version on, a 'load' event handler is added directly as an onload attribute on the iframe's source, whereas previously it was added with attachEvent or addEventListener.
It looks to me like the iframe is throwing a load event for the "about:blank" page, instead of for the submission.
I can revert back to 2.17 or another working version for now, but I'd like to make sure this is fixed upstream;
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?
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?

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 am still new to jQuery and I am trying to figure something out. I have this code:

This is working fine on itself. What is does is when I click a link it loads data into the following div. When done loading it slides out. But I want to change the appearance of the slide. I have tried to do that like this: $(this).show("slide", { direction: "down" }, 1000); But this doesn't work. When I check firebug it says the following: o.easing[this.options.easing || (o.easing.swing ? "swing" : "linear")] is not a function
I'm very new to jQuery, only picked it up yesterday, so there is very little I understand at the moment. I have a website on which I would like to display a real time, time-series chart displaying results from a database that is constantly updated. how to pull live data from my database and display it in an alert box on my sight. One of the replies said I should use jquery to achieve this.

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]...
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 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);

Read the first reply below first/instead, it's probably more helpful than this one
There's a lot of talk about AJAX these days and it seems to me it's turning into a hammer for a lot of problems that aren't really nails. If you want your pages to call home but don't want to have to deal with XML parsing and extremely spotty browser support, here's a very simple way to effect communication from Javascript to the server. The server can only (easily) communicate back on the next page hit with this method, but as a one way conduit from client to server post page rendering it can hardly be beat.
I've set it up with a really simple case that keeps track of the total time each user spends looking at a page in ten second increments. I have, for clarity (I hope) stuck it all in one PHP file, but it'll work the same with any server side language:
<?php
// this block isn't really too well coded or useful, it's intended more as a simple proof of concept
if (isset($_GET['ip']) && ip2long($_GET['ip']) !== false)
{
// if there's a GET variable (this.php?ip=something) and it appears to be a valid ip...
$fname = sha1($_GET['ip']) . '.time'
if (file_exists($fname) && strpos(($pre = file_get_contents($fname)), '='))
{
// if we have a file and it looks like it might be in the right format, increment the value contained therein
list($ip, $time) = explode('=', $pre);
file_put_contents($fname, $ip . '=' . ($time + 10));
}
else
{
// else just write it in and hope for the best
file_put_contents($fname, $_GET['ip'] . '=10');
}
/*
//actually returning an image here can help get the loading message out of browser's status bars
header('Content-type: image/gif');
fpassthru('small.gif');
*/
}
else
{
?>
<html>
<body onload="javascript:setTimeout('serverTick();', 10000);">
<script language="javascript">
var ip = '<?php echo $_SERVER['REMOTE_ADDR']; ?>' // give the javascript an ip or a hash or something to pass back that will be reasonably unique
function serverTick()
{
setTimeout('serverTick();', 10000); // call this function again in 10 seconds
var notshown = new Image();
notshown.src = '<?php echo $_SERVER['PHP_SELF']; ?>?ip=' + ip; // calls this file in attempt to preload an image, instead triggering the above block of PHP
}
</script>
</body>
</html>
<?php
}
?>
This will work in far more browsers than AJAX will, and it's not subject to any domain restriction, it can post to another server without generating security exceptions. It may be possible to get data back in the body of the image and it's definitely possible to get data back coded as image dimensions, if you want to push this method a little further.
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:
