i get error in firebug when i try to get the data from the second url, but when i try the url in comments (the first one) everything is ok,
function build()
{
$.ajax({
type: "GET",
contentType: "application/json",
crossDomain: true,

dataType: "json",
success: function (data)
{
var n=data.links.link[1]['#href'].indexOf("file");
var ContObject=new Object();
ContObject.data=new Object();
ContObject.data["title"]= decodeURI(data.links.link[1] ['#href'].substring(n));
ContObject.state="open";
ContObject.metadata=new Object();
ContObject.metadata["id"]= decodeURI(data.links.link[1]['#href'].substring(n));
var jsonText = JSON.stringify(ContObject);
var output="<div>";
output+= jsonText;
output+="</div>";
document.getElementById("placeholder").innerHTML=output;
alert("success");
},
error: function (data,status)
{
console.log("ERROR");
console.log(status);
}
});
thanks for guidance

In the case, on the server side have some archive restApi.js with REST functions. My REST functions works fine, i test with Prompt Command.
In my client side have some archive index.ejs, And I want to call with this file.
My restApi.js: Server-side
var Client = require('./lib/node-rest-client').Client;
var client = new Client();
var dataLogin = {
data: { "userName":"xxxxx","password":"xxxxxxxxxx","platform":"xxxx" },
headers: { "Content-Type": "application/json" }
};
var numberOrigin = 350;
client.registerMethod("postMethod", "xxxxxxxxxxxxxxxxxx/services/login", "POST");
client.methods.postMethod(dataLogin, function (data, response) {
// parsed response body as js object
// console.log(data);
// raw response
if(Buffer.isBuffer(data)){
data = data.toString('utf8');
console.log(data);
re = /(sessionID: )([^,}]*)/g;
match = re.exec(data);
var sessionid = match[2]
console.log(sessionid);
openRequest(sessionid, numberOrigin); // execute fine
}
});
function openRequest(sessionid, numberOrigin){
numberOrigin+=1;
var dataRequest = {
data: {"sessionID":sessionid,"synchronize":false,"sourceRequest":{"numberOrigin":numberOrigin,"type":"R","description":"Test - DHC","userID":"xxxxxxxxxx","contact":{"name":"Sayuri Mizuguchi","phoneNumber":"xxxxxxxxxx","email":"xxxxxxxxxxxxxxxxxx","department":"IT Bimodal"},"contractID":"1","service":{"code":"504","name":"Deve","category":{"name":"Developers"}}} },
headers: { "Content-Type": "application/json" }
};
client.post("xxxxxxxxxxxxxxxxxxxxxxxxx/services/request/create", dataRequest, function (data, response) {
// parsed response body as js object
// console.log(data);
// raw response
console.log(data);
});
}
My index.ejs: Client side
<html>
<head> ------------- some codes
</head>
<meta ------- />
<body>
<script>
function send() {
$.ajax({
type: "POST",
url: "restApi.js",
data: '{ sendData: "ok" }',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (result) {
alert("successful!" + result.d);
}
});
}
</script>
<script src="restApi.js"></script>
</body>
</html>
I've try see others examples but does not work (Ajax).
And I need to know how to solved this, if have other Best practice for it, please let me knows.
In my console (Chrome) show if I call the ajax function:
SyntaxError: Unexpected token s in JSON at position 2 at JSON.parse (<anonymous>) at parse (C:\xxxxxxxxxxxxxxxxxxxxxxxxx\node_modules\body-parser\lib\types\json.js:88:17) at C:\xxxxxxxxxxxxxxxxxxxxxxxxx\node_modules\body-parser\lib\read.js:116:18
And if I click (BAD Request) show:
Obs.: Same error than app.js, but app.js works fine.
Cannot GET /restApi.js
In the case the file restApi.js Is a folder behind the index.
Folder:
Obs.: public folder have the index.ejs
Your problem is bad url. In case if you have fiule structure like this you have to point as shown in image
Based on the error I think the data you are posting via AJAX is not in correct syntax.
Change function send() as following.
function send() {
var obj = { "sendData" : "ok" };
$.ajax({
type: "POST",
url: "restApi.js",
data: obj,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (result) {
alert("successful!" + result.d);
}
});
}
This should resolve the error you are facing.
Try this now...
function send() {
var obj = {
sendData : "ok"
};
$.ajax({
type: "POST",
url: "Your url",
data: obj,
dataType: "json",
success: function (result) {
alert("successful!" + result.d);
},
error: function (error) {
console.log("error is", error); // let us know what error you wil get.
},
});
}
Your url is not pointing to js/restapi js.
and what code do you have in js/restapi js?
if your action page is app js you have to put it in url.
url:'js/restapi.js',
I have an AJAX request which gets data from the database and then populates the page with the data collected. The problem I am having is that currently the ajax request is in a setInterval which is being called every second.
setInterval(function () {
$.ajax({
method: "POST",
url: "/PLM/FetchPageContent",
dataType: "json",
success: function (data) {
console.log(data);
}
});
}, 1000);
This is fetching the data every second which is a huge strain on the server as it's making a request and then I am calling it again even when the data hasn't come through first time.
Is there a way that I can call the same AJAX request over and over but only after it's finished fetching the data first time and not keep going up?
There are better architectures to accomplish this type of scenario (websockets as mentioned in the comments would be one example), but to do strictly what you're asking, sure! Wrap it in a function that calls itself:
function getData(){
$.ajax({
method: "POST",
url: "/PLM/FetchPageContent",
dataType: "json",
success: function (data) {
console.log(data);
getData();
}
});
}
Replace the setInterval with a setTimeout only once you're done:
function fetchAjax() {
$.ajax({
method: "POST",
url: "/PLM/FetchPageContent",
dataType: "json",
success: function (data) {
console.log(data);
setTimeout(fetchAjax, 1000);
}
});
};
Add a variable to distunguish if ajax call is already underway. If it is, don't do anything. If not, go ahead.
var isAjaxInProgress = false;
setInterval(function () {
if (!isAjaxInProgress){
isAjaxInProgress = true;
$.ajax({
method: "POST",
url: "/PLM/FetchPageContent",
dataType: "json",
success: function (data) {
console.log(data);
isAjaxInProgress = false;
}
});
}
}, 1000);
I am trying to use the newer .done() syntax for a call to .ajax(), but I don't see how to get the data returned from the server into my .done() function. Here is my code:
function checkLink(element) {
var resultImg = $(element).parent().parent().find("img");
resultImg.attr("src", "/resources/img/ajaxLoad.gif");
$.ajax({
type: 'POST',
url: '/services/Check.asmx/CheckThis',
data: '{somedata: \'' + whatever + '\'}',
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: onSuccess,
error: onFailure
}).done(function () { success2(resultImg); });
}
function success2(img) {
img.attr('src', '/resources/img/buttons/check.gif');
}
function onSuccess(data) {
// The response from the function is in the attribute d
if (!data.d) {
alert('failed');
}
else {
alert('hurray!');
}
}
checkLink is called from a simple button push. Both onSuccess() and success2() are firing just fine. But... what I need is the "data" parameter from onSuccess passed to success2... or alternately, be able to pass "resultImg" to onSuccess (although I would prefer using .done instead of the deprecated method). It seems I can either pass my own parameters, or access the JSON result from the AJAX call... but not both. How do I accomplish this?
You can close over the resultImg variable:
function checkLink(element) {
var resultImg = $(element).parent().parent().find("img");
resultImg.attr("src", "/resources/img/ajaxLoad.gif");
$.ajax({
type: 'POST',
url: '/services/Check.asmx/CheckThis',
data: '{somedata: \'' + whatever + '\'}',
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: onSuccess,
error: onFailure
}).done(success2);
function success2(data) {
resultImg.attr('src', '/resources/img/buttons/check.gif');
// do whatever with data
}
function onSuccess(data) {
// The response from the function is in the attribute d
if (!data.d) {
alert('failed');
}
else {
alert('hurray!');
}
}
}
how come when I send ajax request like this everything works
$(".btnDeleteSong").click(function () {
var songId = $(this).attr('name');
$.ajax({
type: 'POST',
url: "/Home/DeleteSong/",
data: { id: songId },
success: ShowMsg("Song deleted successfully"),
error: ShowMsg("There was an error therefore song could not be deleted, please try again"),
dataType: "json"
});
});
But when I add the anonymous function to the success It always showes me the error message although the song is still deleted
$(".btnDeleteSong").click(function () {
var songId = $(this).attr('name');
$.ajax({
type: 'POST',
url: "/Home/DeleteSong/",
data: { id: songId },
success: function () { ShowMsg("Song deleted successfully"); },
error: function () {
ShowMsg("There was an error therefore song could not be deleted, please try again");
},
dataType: "json"
});
});
what if i wanted few things on success of the ajax call, I need to be able to use the anonymous function and I know that's how it should be done, but what am I doing wrong?
I want the success message to show not the error one.
function ShowMsg(parameter) {
$("#msg").find("span").replaceWith(parameter);
$("#msg").css("display", "inline");
$("#msg").fadeOut(2000);
return false;
}
Make sure your action is returning Json data.
"json": Evaluates the response as JSON and returns a JavaScript object. In jQuery 1.4 the JSON data is parsed in a strict manner; any malformed JSON is rejected and a parse error is thrown. (See json.org for more information on proper JSON formatting.)
http://api.jquery.com/jQuery.ajax/
Your action method should surely return Json data. I have the similar code see if that helps.
public ActionResult GetAllByFilter(Student student)
{
return Json(new { data = this.RenderPartialViewToString("PartialStudentList", _studentViewModel.GetBySearchFilter(student).ToList()) });
}
$("#btnSearch").live('click',function () {
var student = {
Name: $("#txtSearchByName").val(),
CourseID: $("#txtSearchByCourseID").val()
};
$.ajax({
url: '/StudentRep/GetAllByFilter',
type: "POST",
data: JSON.stringify(student),
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function(result) {
$("#dialog-modal").dialog("close");
RefreshPartialView(result.data);
}
, error: function() { alert('some error occured!!'); }
});
});
Above code is used to reload a partial view. in your case it should be straight forward.

aspx site:
<script type="text/javascript">
function AjaxTest() {
var codeVal = "hello world";
if (codeVal) {
$.ajax({
type: "POST",
url: "CheckAge",
data: { code: codeVal },
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
cache: false,
success: function (result) {
alert("in ajax success");
},
error: function () {
alert("error");
}
});
}
}
Its double checked that the javascript function is called.
Controller:
[HttpPost]
public JsonResult CheckAge(String code)
{
return Json("abc");
}
It ended up always in the ajax - error - function.
The Controller function isnt called anyway. Why?
Why get I always an error?
What is wrong?
Check your url that you are posting to. It seems that you are missing the controller part. E.g. it should read /{controller}/{action}.
If that script is directly in the view (i.e. not in an external javascript file) you could have something like:
$.ajax({
type: "POST",
url: <%= Url.Action("CheckAge", "ControllerName") %>,
data: { code: codeVal },
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
cache: false,
success: function (result) {
alert("in ajax success");
},
error: function () {
alert("error");
}
});
Also, I find it advantageous to use firebug to debug ajax stuff. You can set break points in your javascript and also see all the requests and responses.
HTHs,
Charles
EDIT: Try simplifying things... e.g.
$.post('<%= Url.Action("CheckAge", "ControllerName") %>',
{ code: codeVal },
function (data) {
alert("in ajax success");
},
"json");
