I am trying to post data to mvc controller and i am unsuccessful doing so..hope i get any help...here is the xhrpost call
var reqObj =
{
Id: dojo.byId("Id").value,
Password: dojo.byId("Password").value
};
console.log(reqObj );
var xhrArgs = {
url: '~/FormController/ValidateRequest',
postData: reqObj ,
handleAs: "json",
headers: { "Content-Type": "application/json", "Accept": "application/json"},
load: function (data) {
alert(data);
}
}
var deffered = dXhr.post(xhrArgs);
console.log(deffered);
}
I could not even see a post call in firebug....what might be the problem..any clues?
Thanks in advance.
I see a couple issues:
First you populate reqObj with the values you want to post, however, you put "request" into your xhrArgs.
Second, you will need to convert reqObj to json (dojo.toJson), since you are handling the post as json.
Also, I don't see a reference to the dojo.xhrPost method? Are you using sometype of framework that encapsulates that?

So I am using this code to post:
$.ajax({
url: '/validator/ValidationController/validate',
data : JSON.stringify(parameters),
contentType : 'application/json',
type : 'POST'
})
And this to receive, both being triggered by the same button press. But it's just getting a null object.
def validate(){
Thread.currentThread().sleep(1000)
def parameters = request.JSON;
assert parameters.a == "a_value";
}
When I hover over the validate function, it's referred to as: Object validator.ValidationController.validate() I'm assuming the url is wrong.
Note: I am pretty inexperienced with this, speaking to me like I'm 5 is encouraged!
We would need more code to see how you are sending and receiving but it seems like you are not handling the asynchronous aspect. In simple terms, you are sending out the request and immediately trying to handle the response, even though it is not back yet and even though you tried to sleep. Check out the complete config for the ajax function. Something like this:
$.ajax({
url: '/validator/ValidationController/validate',
data : JSON.stringify(parameters),
contentType : 'application/json',
type : 'POST',
complete: function(request, success){
validate(request)
}
})
def validate(request){
Thread.currentThread().sleep(1000)
def parameters = request.JSON;
assert parameters.a == "a_value";
}
I've the following generic PostTo method which can be used to post data to an ASP.NET MVc Controller, without the need for repetitive mark-up, I'm pretty sure it was working at one point, but for some reason, the success callback (any of it) doesn't get called.
Any thoughts? Everything looks right, and the server is responding with a valid 200 OK response.
It is however, an empty response. I tried a different (and empty) dataType value, but nothing changed.
function PostTo(controller, action, data, successCallback) {
$.ajax({
url: Settings.HostPath + controller + "/" + action,
type: "POST",
cache: false,
dataType: "json",
data: data,
success: function (data, textStatus, jqXHR) {
if (typeof (successCallback) != "undefined")
successCallback.call(this, data);
}
});
}
ajax method in your script, excepts json data from the server, but as you told in comments, your actions returns nothing (i thinks it's returns EmptyResult).
So, add any json result in your action:
public ActionResult Test()
{
return Json(new {Success = true});
}
I'm trying to delete an entry from the database by odata. I get the error message
{"error":{"code":"","message":{"lang":"en-US","value":"Bad Request - Error in query syntax."}}}
my code:
function deleteMonthEntry() {
var item = actMonthEntries.getItem(listIndex);
var queryString = "Stundens(" + item.data.datensatz_id + ")?$format=json";
var requestUrl = serviceUrl + queryString;
WinJS.xhr({
type: "delete",
url: requestUrl,
headers: {
"Content-type": "application/json"
}
}).done(
function complete(response) {
},
function (error) {
console.log(error);
}
);
}
My request URL looks like this:
requestUrl = "http://localhost:51893/TimeSheetWebservice.svc/Stundens(305233)?$format=json"
Thanks

At least I found the solution:
I've entered an filter request to my service like this:
TimeSheetWebservice.svc/Stundens?$filter=datensatz_id eq 305221
this returned the correct entry with this link:
TimeSheetWebservice.svc/Stundens(305221M)
So if I enter a M after the ID, everything works fin. But I have no idea where this M comes from.
Can anyone tell me the reason for this M? It does not belong to the ID. The ID is this
305221

Are you sure the server you're talking to supports the $format query option? Many don't. I would try removing that part of the request URI, and instead modify your headers value to specify an Accept header:
headers: {
"Content-Type": "application/json",
"Accept": "application/json"
}
For servers where $format is allowed, giving it a json value is equivalent to providing an Accept header with the application/json MIME type.
In general, for a DELETE operation, the Accept header or $format value only matters for error cases. With a successful DELETE, the response payload body will be empty, so there's no need for the server to know about your format preference.
I have problem with autocomplete. The code below is returnig me
["foo#foo.com","bar#bar.com"]
$('.autocomplete').keyup(function() {
tid = $(this).attr('id')
$(this).autocomplete({
source: function (req, resp){
$.ajax(
{
url: "autocompl.asp",
data:$("#msgForm").serialize() + "&field="+tid ,
success : function( resp ) {
return resp
}
})
}
});
});
But the suggestions don't appear. It worked for me when I have called autocomplete without any extra parameters.
Any clue?
Thanks in advance

Note that one of your parameters for the source function is resp, and you're using another resp afterwards. I think you need to use the first resp to send the response object back.
I'm using this as well and this works for me (Instead of sending an array of values, I'm sending an array of objects with two attributes, but I don't think it's mandatory).
id
label
so the code inside the ajax success should look something like this (my data variable is your second resp variable, a different name to avoid mixup):
success: function(data) {
for (i in data) {
a = {}
a.id = data[i]
a.label = data[i]
options.push(a)
}
resp(options)
}
I'm trying to send the following data to the server but at the server side I don't see the json parameter that I'm sending. Can anyone tell me what I'm doing wrong?
Below you can see the code.
Prototype:
send_data_url = "change"
hash = $H({"blocks": [{"h": "2", "area": [{"width": "96%", "els": [{"title": "first", "mand": true}, {"title": "second", "mand": false}]}]}]});
var request_array_json = hash.toJSON();
new Ajax.Request(send_data_url, {
method: 'post',
parameters: request_array_json,
contentType: 'application/json;'
});
Rails:
def change()
debugger
my_json = ActiveSupport::JSON.decode(params["_json"])
end
In the controller I see that the params object does not have the json parameter.
It only shows the action and the controller:
{"action"=>"change", "id"=>nil, "controller"=>"default/test"}
Note: I'm using prototype 1.6 qnd rails 2.3.2.
I found a solution using a plugin called json_request.
To get this working nicely, I also wrapped Ajax.Request with a new class that can send complex JSON objects. Example code:
Ajax.JSON = Class.create(Ajax.Request, {
initialize: function($super, url, options) {
options = options || {};
options.contentType = ‘application/x-www-form-urlencoded’;
options.postBody = Object.toJSON(options.object);
$super(url, options);
}
});
new Ajax.JSON(url, { object: myObject });
