$.getJSON to $.ajax syntax?

I have this working .getJSON
$.getJSON('data3.json', function (data) {
})
If convert to $.ajax What should be the value for data?
$.ajax({
type: 'GET',
url: 'data3.json',
datatype: 'json',
data: ?,
success: function(data) {
}
});
You should try this
In the ajax, they are not compulsory to pass some parameters like data, datatype etc.
So you can call ajax without data parameter
$.ajax({
type: 'GET',
url: 'data3.json',
datatype: 'json',
success: function(data) {
}
});

Unable to receive data using AJAX post in Laravel

I am trying to send some variables(data),one is the checkbox text, and other is the value in the textarea field to the controller in Laravel through ajax, below is the script:
<script>
$('#btn1').on('click', function() {
$('input[type="checkbox"]').on('click', function() {
var aa=$(this).next('label').text();
var bb=$('textarea#txt2').val();
$.ajaxSetup({
headers:
{'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')}
});
$.ajax({
type: "POST",
url: "/masterdata",
//dataType: 'json',
data: {aa,bb},
success:function(){
console.log(data);
}
,error:function(){
console.log("Error!!!!");
}
});
});
});
</script>
On trying to retrieve the request values in the controller, only the request token gets displayed, and the ajax function doesn't display the success or error message either.What am I missing here?
you need to set a variable on ajax success like this:
$.ajax({
type: "POST",
url: "/masterdata",
//dataType: 'json',
data: {aa,bb},
success:function(response){
console.log(response);
}
,error:function(){
console.log("Error!!!!");
}
});
Try your data as in this format:
data:{'posa': aa, 'posb': bb},
and
success:function(data){
console.log(data);
}
Hope this helps.
i found two issue in your ajax request.
you have to change data: {aa,bb}, to object like data: {aa : aa, bb : bb},
Your success response log is wrong. Current code success:function(), it should be success:function(data)
Full output of new code is :
<script>
$('#btn1').on('click', function() {
$('input[type="checkbox"]').on('click', function() {
var aa=$(this).next('label').text();
var bb=$('textarea#txt2').val();
$.ajaxSetup({
headers:
{'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')}
});
$.ajax({
type: "POST",
url: "/masterdata",
dataType: 'json',
data: {aa : aa, bb : bb},
processData: false,
cache: false,
async :false,
success:function(data){
console.log(data);
}
,error:function(){
console.log("Error!!!!");
}
});
});
});
</script>
To get parameter value in controller use
/**
* Store.
*
* #param Request $request
* #return Response
*/
public function store(Request $request)
{
$aa = $request->input('aa');
$bb = $request->input('bb');
//Your code here
}
<script>
$('#btn1').on('click', function() {
$('input[type="checkbox"]').on('click', function() {
var aa=$(this).next('label').text();
var bb=$('textarea#txt2').val();
$.ajaxSetup({
headers:
{'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')}
});
$.ajax({
type: "POST",
url: "/masterdata",
//dataType: 'json',
data: 'aa=test'+'&bb=test',
success:function(){
console.log(data);
}
,error:function(){
console.log("Error!!!!");
}
});
});
});
</script>

How to Display Json Data when ajax request is success

Here I am using Ajax+Mvc when I call my data from database it comes in Json format but how can I display that data in div?
Html
<div id="Div1">
</div>
<b>Get data</b><input type="button" id="BtnGetData" value="GetData" />
When user click on BtnGetData the data should be display in #Div1 Here my AJax working fine.But please suggest me where to write $('#Div1').load();
$('#BtnGetData').click(function () {
alert('ok data')
$.ajax({
url: '/Home/Getdata',
method: "GET",
type: "JSON",
contentType: 'application/json; charset=utf-8',
data: JSON.stringify(),
})
})
MvcController
public JsonResult Getdata()
{
var x = Objrepo.GetEmplo();
return new JsonResult { Data = x, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
}
You can write to the div on the success function of your $.ajax call.
eg:
$('#BtnGetData').click(function () {
$.ajax({
url: '/Home/Getdata',
method: "GET",
type: "JSON",
contentType: 'application/json; charset=utf-8',
data: JSON.stringify(),
success: function (data) {
console.log(data);
}
})
});
You need to add a success callback to your ajax:
$('#BtnGetData').click(function () {
alert('ok data')
$.ajax({
url: '/Home/Getdata',
method: "GET",
type: "JSON",
contentType: 'application/json; charset=utf-8',
success: function(data){
$("#Div1").append(data);
}
})
})
There is no need to add the data property to the ajax if your are not sending anything.
May be, you can add this function in your script.
$('#BtnGetData').click(function () {
alert('ok data')
$.ajax({
url: '/Home/Getdata',
method: "GET",
type: "JSON",
contentType: 'application/json; charset=utf-8',
data: JSON.stringify(),
writeResponse(data)
})
});
writeResponse(data){
$("Div1").html(data);
};

Ajax post parameters ASP.NET MVC 3

Hello guys i have the next ajax call for login. I serialize the form and send the data to server and return redirect url link. My problem is that my url after post is like
http://localhost:50802/?username=&password= and not http://localhost:50802/Home
$.ajax({
type: "POST",
url: "Login/Login",
dataType: 'json',
contentType: "application/json; charset=utf-8",
data: loginJson,
cache: true,
async: false,
complete: function (result) {
alert(result.link);
window.location.replace = "/Home/Index";
},
error: function () {
$("#username").val("");
$("#password").val("");
alert("Wrong Username or Password!");
}
}); //end ajax call
It looks like you wrote this $.ajax call in the .click event of a submit button or in the .submit event of a form without canceling the default action by returning false from the callback or by calling preventDefault on the argument. Here's how your code should look like:
$('#id_of_your_form').submit(function(e) {
e.preventdefault(); // <-- That's what I am talking about and what you forgot
$.ajax({
type: "POST",
url: "Login/Login",
dataType: 'json',
contentType: "application/json; charset=utf-8",
data: loginJson,
cache: true,
async: false,
complete: function (result) {
window.location.replace = "/Home/Index";
},
error: function () {
$("#username").val("");
$("#password").val("");
alert("Wrong Username or Password!");
}
}); //end ajax call
});
Also async: false,????? You know what this does, do you? That's not AJAX. That's a blocking synchronous call to your webserver during which the client browser would be frozen like during the Ice Age 2 ruining all user experience.
Try returning false at the end of your submit function
$('#id_of_your_form').submit(function(e) {
$.ajax({
type: "POST",
url: "Login/Login",
dataType: 'json',
contentType: "application/json; charset=utf-8",
data: loginJson,
cache: true,
async: false,
complete: function (result) {
window.location = "/Home/Index";
},
error: function () {
$("#username").val("");
$("#password").val("");
alert("Wrong Username or Password!");
}
}); //end ajax call
return false; });
Another option would of course be to return the correct redirectlink from the controller instead of overriding it in the java script.

MVC2: Ajax call runs always in error function. Why? Whats wrong?

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");
