Don't know if it matters, but the msg.d is about 300 rows long. I get properly formatted Json data when I alert msg.d.
$("#supplierSelect").autocomplete({
source: function( request, response ) {
$.ajax({
type: "POST",
url: "SupplierAdmin.aspx/PopulateSupplierSelectDropDownList",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
response( $.map( msg.d, function( item ) {
return {
label: item.title,
value: item.turninId
}
}));
}
});
}
}).fadeIn();
Lots of thanks if you can tell me how to only fadeIn when success.
Edit: The "properly formatted Json data" actually has quotes around the label and value, and the ordering is switched. Checking now to see if it makes a difference. Sorry for incomplete info.
Edit2: I went with response( $($.parseJSON(msg.d)).map( function()... instead, and now when I type anything, the autocomplete drops down the whole list of names and selecting one puts the value in the box. Am I right to assume this isn't correct functionality?
Needed to add parseJSON to the map.

I have a very basic ajax call to alert the data that was reported from the server
$.ajax({
type: "POST",
url: "/someform/act", //edit utl to url
data: { changed: JSON.stringify(plainData) }, //edit to include
success: function(data) {
alert(data); //data not $data
},
error: function() {
//error condition code
}
});
According to the docs on the jquery website regarding data field on the success callback, it says that data returned is the data from the server. However for some strange reason when I alert $data, I get [object Object]
I was expecting to see something like this, since that is what the server would send back
<status>0</status>
EDIT:
data is also passed along as the POST
You need to use JSON.stringify(data) in the alert to get anything readable.
Also, $data is a completely different variable name than data.
alert() prints the string representation of the arguments - hence if you pass an object, you'll get [object Object].
To inspect data, use console.log(data) better.
If you server send a JSON, you need to put dataType: 'json' to your ajax call. Be aware there's some mistake in your ajax call.
$.ajax({
type: "POST",
url: "/someform/act", // NOT 'UTL',
data: {
key: value,
key2: value2
},
// or data: plaindata, // If 'plaindata' is an object.
dataType: 'json',
success: function(data) {
console.log(data); // As moonwave99 said
},
error: function() {
//error condition code
}
});
EDIT
When sending data, you should send an object. jQuery will handle the array to sned it to the server. So if plain data is an object, it should be like this
data: plainData,
If you're sending data via $.ajax({...}), the Network tab of your browser inspector might be showing [object Object] in the Payload (Chrome) / Request (Firefox) sub-tab, like in the following image (Firefox):
The reason for this might be in the way you're forming your AJAX call. Specifically:
$.ajax({
url: '/ajax/example-endpoint',
data: {'fooKey':fooData,'barKey':barData},
type: 'post',
cache: false,
contentType: false, // this one will turn your data into something like fooKey=fooData&barKey=barData
processData: false, // and this one will make it [object Object]:""
beforeSend: function() {
// whatever it is you need to do
},
success: function(data) {
// do stuff
},
error: function(desc, err) {
// do stuff
}
});
When combined, contentType: false and processData: false turn your data into [object Object], because you're actually telling your AJAX call to ignore the content type of whatever is being sent, and not to process it.
If it's IIS, try creating a site outside of the Default Web Site (for example localhost/ajax1). For example a new site ajax1, place it not in the DefaultAppPool, but in your pool, for example ajax1. Try http://ajax1
I switched to POST searches using ajax in my application so I can start using the date range. However it seems no matter what I post it keeps returning the first 10 results in my index. The true results are in the 30k range.
amplify.request.define("searchPostRequest", "ajax", {
url: "http://leServer:9200/people/person/_search",
type: "POST",
dataType: 'jsonp',
contentType: 'application/json'
});
self.advancedSearchPostQuery = {
query: {
term: {
locationNumber:479
}
}
};
console.log(self.advancedSearchPostQuery);
amplify.request({
resourceId: "searchPostRequest",
data: JSON.stringify(self.advancedSearchPostQuery),
success: function (data) {
console.log(data.hits.hits.length);
}
});
If this is your actual code, your problem might simply be that your
advancedSearchPostQuery isn't valid JSON.
You need to apply quotes:
advancedSearchPostQuery = {
"query": {
"term": {
"locationNumber": 479
}
}
}
And I'm not sure if you need to stringify the object, but I'm not familiar with amplifyJS, so double check on that as well if amplifyjs is expecting an object or a string.
If that doesn't help check if your query returns the correct results when running from command line through curl.
After doing more debugging I found that the request was being sent as a GET even though I had explicitly set it to post. Moving the data type to json, from jsonp let the request be sent as a POST, which resolved the issue. However this causes an issue in IE where the request is not sent at all due to the request being sent to another domain.
amplify.request.define("searchPostRequest", "ajax", {
url: "http://leServer:9200/people/person/_search",
type: "POST",
dataType: 'json',
contentType: 'application/json'
});
Ι need to use a combination of the following 2 scripts but despite all the combinations I've done so far, I fail to get it to work 100%.
I use a colorbox to display products detail pages in which there is a form with various fields for adding the items to the cart. Upon submitting the form, I want to show an alert and then close the colorbox so that the underlying page (that opened the colorbox in the forst place) stays as is.
With this script
$("#productadd").submit(function(){ // WORKS FINE EXCEPT THE ENCODING
$.post(
$(this).attr('action'),
$(this).serialize(),
function(data){
alert('Product was added to your order');
$().colorbox.close();
});
everything works fine except for the encoding which in my case is iso-8859-7 (greek).
If I use this script then encoding is ok but the post is being made with the default behaviour, redirection to the url defined in the form's action.
$("#productadd").submit(function(){ //ENCODING OK, COLORBOX.CLOSE() AND ALERT FAIL
$.ajax({
data: data,
type: "POST",
url: $(this).attr('action'),
dataType: 'json',
beforeSend : function(xhr) {
xhr.setRequestHeader('Accept', "text/html; charset=iso-8859-7");
},
success: function(json) {
alert('Product added to cart!'),
$().colorbox.close(),
itemAddCallback(json);
},
error: function (xhr, textStatus, errorThrown) {
$("#error").html(xhr.responseText);
}
});
If there's a jQuery equivalent for xhr.setRequestHeader('Accept', "text/html; charset=iso-8859-7") I'd be more than happy to use it. Also, what do I declare as data: so I dont get a 'data is not defined' error? (despite the error, date submits fine).
UPDATE: After various suggestions from those who answered so far, this is what my code looks like:
$("#productadd").submit(function(){
$.ajax({
data: $(this).serialize(),
type: "POST",
url: $(this).attr('action'),
dataType: 'text',
mimeType: "text/html; iso-8859-7",
success: function() {
alert('Item added to your order'),
$().colorbox.close();
},
error: function (xhr, textStatus, errorThrown) {
$("#error").html(xhr.responseText);
}
});
My only problem is that although it submits and displays the alert etc, the submitted data is encoded in utf-8 instead of iso-8859-7, any ideas?
Please check the documentation:
http://api.jquery.com/jQuery.ajax/
Find mimeType property.
mimeType(added 1.5.1)String
A mime type to override the XHR mime type.
Therefore you need to add following:
$.ajax({
data: data,
type: "POST",
mimeType: "text/html; charset=iso-8859-7"...
In the shorthand POST request you send $(this).serialize() as data, so I suppose you want to send the same form data in the other request.
To debug the requests, use your browsers net panel and find out if the requests actually fire and what the responses are (F12 then Net > XHR).
Hope this helps!
I have come across a peculiar item in JQuery that I am hoping somebody can help me to understand.
I've spent much of the day trying to get JQUERY's AJAX 'success' function to be raised when returning JSON from the server.
I checked the JSON # JSONLint to ensure validity, checked encoding, tried different headers, but still PROBLEMS.
After a couple hours, I switched the url (by accident!)
from
http//www.testing.com/_r4444/myfile.php
to the exact same thing WITHOUT the www... and it suddenly worked.
I have no clue why this would be the case - any ideas?
the snippet follows
$(document).ready(function() {
$.ajax( {
type: "POST",
contentType: "application/json",
url: "http://testing.com/_r4444/getter.php",
beforeSend: function(x) {
if(x && x.overrideMimeType) x.overrideMimeType("application/json;charset=UTF-8");
},
data: "pass=TEST",
dataType: "json",
error: function (xhr, status) {
alert(status);
},
success: function (result) {
alert(result);
}
});
});
Are you using "www" on the page in the browser?
Try switching the call to not include the domain, like:
"/_r4444/getter.php" instead of the full domain.
Imagine I run this:
$.ajax({
type: 'POST',
url: '/ajax/watch.php',
data: {'watch':'aukcia', 'id':aukciaID},
complete: function(responseText){
alert(responseText);
}
});
Inside /ajax/watch.php, let's say I have this:
echo 'this is what I want';
And the alert(responseText) returns:
[object Object]
Instead of my text string that I need.
Any help, please?
Looks like somehow your jQuery is returning the XMLHttpRequest object, instead of your response.
If that is the case, you should ask for its responseText property, like this:
$.ajax({
type: 'POST',
url: '/ajax/watch.php',
data: {'watch':'aukcia', 'id':aukciaID},
complete: function(r){
alert(r.responseText);
}
});
However, if that does not work, you might be actually receiving a JSON response, and the [object Object] you are seeing might be your browser's representation of your JSON response.
You should be able to inspect its contents by navigating around the object properties. However, if you want, you can also tell jQuery not to parse your JSON response, by including dataType: 'text' on your call:
$.ajax({
type: 'POST',
url: '/ajax/watch.php',
data: {'watch':'aukcia', 'id':aukciaID},
dataType: 'text',
complete: function(data){
alert(data);
}
});
For more information, see: http://api.jquery.com/jQuery.ajax/
Use on your client side ajax like this
$.ajax({
type: "POST",
url: "insert-data.php",
data:
{student_name:student_name,student_roll_no:student_roll_no
,student_class:student_class},
dataType: "JSON",
success: function(data) {
$("#message").html(data);
$("p").addClass("alert alert-success");
},
error: function(err) {
alert(err);
}
});
in server side after query excecute you may use it give success when you query success false when your query has fault
if($stmt->execute())
{
$res="Data Inserted Successfully:";
echo json_encode($res);
}
else {
$error="Not Inserted,Some Probelm occur.";
echo json_encode($error);
}
I think you are receiving this in your server respones
{message:'hello world'}
if thats the case then use
JSON.parse(data.responseText).message
to convert the json string into javascript object and access your message property.
