I have a error when I tried to send post data with ajax() method.
I have a array with :
acpitool
aide
I use encodeURIComponent() for passing the array with data: but the ajax method fail.
Could you help me?
Thanks
Edit :
This is the ajax call
$.ajax({
url: 'AjaxSearch.php',
dataType: 'json',
data: param+"="+package,
type: 'POST',
success: function(data) {
}
});
package is a Array like this :
var package = new array("acpitool","aide");
Sometimes, I have this :
var package = new array("bonnie++");
For both, I have an error :
Uncaught Syntax error, unrecognized expression: +
$.ajax({
url: 'AjaxSearch.php',
dataType: 'json',
data: {
param: $.param(package);
}
type: 'POST',
success: function(data) {
}
});
use jQuerys .param() method to serialize an array.
Description: Create a serialized representation of an array or object, suitable for use in a URL query string or Ajax request.
update
based on your comment, try this
data: {
param: package.join(',');
}

I am trying to get a json response from the comicvine api but am getting the following error. comicvine.gamespot.com/:1 Uncaught SyntaxError: Unexpected token :
I see my json result, formatted, in the response body but am getting the console error above.
export function getSeriesFromComicVine() {
const url = "http://comicvine.gamespot.com/api/characters/?api_key=f18c6362ec6d4c0d7b6d550f36478c1cd6c04a49&filter=gender:male,name:hawkeye&format=json&callback=?";
$.ajax({
url: url,
// data: {test: "test"},
type: 'GET',
crossDomain: true,
jsonpCallback: 'callback',
dataType: 'jsonp',
jsonp: false,
jsonpCallback: "myJsonMethod"
success: function (data) {
console.log(data);
}
});
}
You need to set format=jsonp not json
the jsonp callback parameter name needs to be json_callback according to comicvine.gamespot.com - I found this out by going to url https://comicvine.gamespot.com/api/characters/?api_key=[your api key]&filter=gender:male,name:hawkeye&format=jsonp in the browser, and it told me what was missing - very friendly API - the response had an error value
"'jsonp' format requires a 'json_callback' argument"
and no need for callback=? in the url - seeing as jquery adds the callback parameter and it isn't named callback
function getSeriesFromComicVine() {
const url = "https://comicvine.gamespot.com/api/characters/?api_key=[your api key]&filter=gender:male,name:hawkeye&format=jsonp";
$.ajax({
url: url,
type: 'GET',
dataType: 'jsonp',
jsonp: "json_callback",
success: function (data) {
console.log(data);
}
});
}
I have My jquery function that is returning me data of the formatt:
{"Suggestions":[{"name":"RR Restaurant","category_id":"166","locality":"Gayathri Nagar","listing_info":"listing","random_id":"1ll0f0wJ"},{"name":"Oko Restaurant","category_id":"166","locality":"Kumara Krupa","listing_info":"listing","random_id":"0F7ZGV9p"},{"name":"H2O Restaurant","category_id":"166","locality":"Maratha Halli","listing_info":"listing","random_id":"0JNPOyuP"},{"name":"Taj Restaurant","category_id":"166","locality":"Shivaji Nagar","listing_info":"listing","random_id":"7GeA0Kfq"},{"name":"PSR Restaurant","category_id":"166","locality":"Peenya Industrial Area","listing_info":"listing","random_id":"cRvJCwQ3"},{"name":"ac restaurant","category_id":"166","listing_info":"keyword"},{"name":"Indian Restaurant","category_id":"166","listing_info":"keyword"},{"name":"goan restaurant","category_id":"166","listing_info":"keyword"},{"name":"thai restaurant","category_id":"166","listing_info":"keyword"},{"name":"andhra restaurant","category_id":"166","listing_info":"keyword"}],"ImpressionID":"test"}
I wish to parse the same to get multiple variables with The field "Name" and "Random Id" in different js variables
$("#what").on("keypress", function() {
$.ajax({
type: "GET",
cache: false,
url: "/AutoComplete.do",
data: {
query: 'Pest',
city: 'Bangalore'
}, // multiple data sent using ajax
success: function(data) {
alert();
}
});
});
My JSON object seems to be nested with "Suggestions" as the parent. Please help.
If you add a property to $.ajax function you be ensure that is json parsing:
dataType: 'json'
EDIT
To iterate above the string you can use for(in) or each() jquery
json = "[{'key':'value'},{'key':'value']";
for(var i in json) {
console.log(json[i]);
//if you see in console [OBJECT Object] you are
//in a new object you must to iterate nested of this.
}
$("#what").on("keypress", function() {
$.ajax({
type: "GET",
dataType: "JSON", //You need this to be inserted in your ajax call.
cache: false,
url: "/AutoComplete.do",
data: {
query: 'Pest',
city: 'Bangalore'
}, // multiple data sent using ajax
success: function(data) {
alert();
}
});
});
After insert dataType you can probably do this.
console.log(data.Suggestions);
Also take a look at the API Doc at below url regardless of dataType.
http://api.jquery.com/jquery.ajax/
The data object you are specifying is what will be sent as the arguments to your success method, if you use the GET method.
$("#what).on("keypress", function() {
$.get("/AutoComplete.do", function(response) {
var data = JSON.parse(response);
//data.suggestions = [lots of objects];
//data.suggestions[0].locality = "Gayathri Nagar"
});
});
I'm sending from view using jQuery to MVC post action
function DoSomething(passedId) {
$.ajax({
method: "POST",
dataType: 'text',
url: '/MyController/SomeAction/',
data: { id: passedId}
}).done(function (data) {
//
});
}
And inside MyController
[HttpPost]
public ActionResult SomeAction(int id)
{
...
}
In Firebug console I'm getting 404 error.
You didn't said which version of jquery you are using. Please check jquery version and in case that this version is < 1.9.0 you should instead of
method: "POST"
use
type: "POST"
this is an alias for method, and according to jquery official documentation you should use type if you're using versions of jQuery prior to 1.9.0.
function DoSomething(passedId) {
$.ajax({
type: "POST",
dataType: 'text',
url: '/MyController/SomeAction/',
data: { id: passedId}
}).done(function (data) {
...
});
}
Tested above code and it works (each request enter inside mvc controller http post SomeAction action).
In the RFC 2616 the code 404 indicates that the server has not found anything matching the Request-URI.
So you need to look at your URL parameter.
Try the MVC conventional call using :
url: '#Url.Action("SomeAction", "MyController")',
To resolve the 404 issue:
There are a few options to resolve this. You controller/action cannot be find the way it is describe.
-If you are in a view that is in the controller for which the action your are trying to call is located, then:
url: 'SomeAction',
-If you are trying to call an action from another controller, OtherController, for example, then:
url: 'Other/SomeAction',
-To add to another answer, if you are calling your ajax inside the view (and NOT in a javascript file) then you can also use (for a controller called SomeController):
url: '#Url.Action("SomeAction", "Some")',
Additional Items Of Note:
You do not specify a content type for json (contentType indicates what you are sending):
contentType: "application/json; charset=utf-8",
I can't tell, based on your action if you are expecting 'text' or something else. However, unless expecting 'json', I would remove the data part.
You need to stringify your data
JSON.stringify(data: { id: passedId}),
In the end, I would expect it to look something like:
function DoSomething(passedId) {
var url = "SomeAction"; //if action is in OtherController then: "Other/SomeAction"
$.ajax({
method: "POST",
url: url,
data: JSON.stringify({ id: passedId}),
contentType: "application/json; charset=utf-8"
}).done(function (data) {
//
});
}
The slash at the beginning of this designates an absolute path, not a relative one.
/MyController/SomeAction/
You should include a URL or relative path.. maybe
'MyController/SomeAction/ajax.php'
or the full URL
'http://example.com/myajaxcontroller/someaction/ajax.php'
or stolen from the other guys answer
url: '#Url.Action("SomeAction", "MyController")',
To address others on here, I don't think the datatype is the
problem... OP says "I'm getting 404 error."
contentType is the type of data you're sending, so
application/json; charset=utf-8 is a common one, as is
application/x-www-form-urlencoded; charset=UTF-8, which is the
default.
dataType is what you're expecting back from the server: json, html,
text, etc. jQuery will use this to figure out how to populate the success function's parameter.
Write the code this way:
function DoSomething(passedId) {
$.ajax({
url: 'yourController/SomeAction',
type: 'POST',
data: { id: passedId},
dataType: 'json',
error: function (ex) {alert(ex.responseText)},
success: function (data)
{
if (data.Results != null) {
//use the return values
});
}
}
});
}
and the controller
public JsonResult SomeAction(int id)
{
try
{
return Json(new { Results = "Text To return or send some object or an list, etc"}, JsonRequestBehavior.AllowGet);
}
catch (Exception)
{
throw;
}
}
Finally, check that the controller has its respective view. :)
and and the library of "jQuery" updated.
just in case.
use the following ajax call
var datum = { id: passedId };
$.ajax({
url: url, // your url
type: 'POST',
data: JSON.stringify(datum),
contentType: 'application/json; charset=utf-8',
beforeSend: function () {
},
complete: function () {
},
success: function (user, status, XHR) {
},
error: function (req, status, error) {
}
});
UpDated
public ActionResult SomeAction(int id){} should accept string parameter instead of int
I am trying to run post request to parse json format data into the page. An example query is:
$("#click").click(function () {
$.ajax({
type: "POST",
url: "http://ut-pc-236:9000/kanye/flow/search",
contentType: "application/json;charset=UTF-8",
data: {
"fromDate":"2011-01-01",
"toDate":"2011-03-16T14:35:00Z",
"limitTotalFlows":1000,
"operator":"AND",
"keyValues":[ "J0419:E", "J0410:AMPY", "J1043:BEDFORD" ]
},
success: function (data) {
console.log(data);
}
});
});
but it gives an error - bad request (400). I guess it should be some syntax error since the get method works ok. If anyone can help I would really appreciate it. Thanks
You're not sending a valid json object as you claim to be doing with the contentType.
JSON.stringify your data:
data: JSON.stringify({
"fromDate":"2011-01-01",
"toDate":"2011-03-16T14:35:00Z",
"limitTotalFlows":1000,
"operator":"AND",
"keyValues":[ "J0419:E", "J0410:AMPY", "J1043:BEDFORD" ]
}),
I'm practicing with the PHP RestServer Class. But I can't get the correct data from it if I use an Ajax call on it. I have the following code:
<?php
require_once "locationOfRestServer.php";
class HelloWorld
{
public static function sayHello()
{
return array("Response" => "Hello World");
}
}
$rest = new RestServer('HelloWorld');
$rest->handle();
And in my javascript file I use the following:
this.helloWorld = function() {
$.ajax({
url: 'locationOfHelloWorld.php'
type: 'POST',
dataType: 'json',
success: function(data){
console.log(data);
}
});
};
I get the following error:
error: "No method was requested."
Because; whenever I use it, I have to go to localhost/HelloWorld.php?method=sayHello which is actually working.
So I added the following line to the ajax call:
method: 'sayHello',
But it still keeps giving me the same error.
Try this,
$.ajax({
url: 'locationOfHelloWorld.php'
type: 'GET',// use GET method according to your working url
data:{method: 'sayHello'},// use method in data parameter
dataType: 'json',
success: function(data){
console.log(data);
}
});
