When i call ajax there url wrong why? - ajax

I have a one Edit.cshtml page and there is 1 partial template call. in that template I make an ajax call and my controller is home and action name is savedata
ajax function
$.ajax({
url: "CountryZone/SaveData",
type: 'POST',
data: { data: selectedID, id: id },
dataType: "html",
success: function (result) {
alert("Success");
},
error: function (result) {
data.str = null;
alert("Error");
},
});
controller:--
public ActionResult Savedata(string data, int CountryZoneId)
{
return null;
}
now when my ajax call is going
there is url wrong :--- url is Home/edit/Home/Savedata instead of this there is only Home/SaveData

It's a bad idea to hardcode urls in MVC application.
Change this line:
url: "CountryZone/SaveData",
To this:
url: "/CountryZone/SaveData",
I suggest at least using Url.Action in the view and storing it in the js variable.

Use standard MVC code as below:
url: '#Url.Action("SaveData","CountryZone")',
Full Code
$.ajax({
url: '#Url.Action("SaveData","CountryZone")',
type: 'POST',
data: { data: selectedID, CountryZoneId: id },
dataType: "html",
success: function (result) {
alert("Success");
},
error: function (result) {
data.str = null;
alert("Error");
},
});
[HttpPost]
public ActionResult Savedata(string data, int CountryZoneId)
{
return null;
}

Unable to 'call' controller action from ajax post

I'm using net.core for the first time today and I'm trying to call an action method from an ajax call:
My Ajax call (from a normal HTML page)
$("#contactMap").click(function (e) {
e.preventDefault();
var url = "/MapObjects/mapContact";
//I've tried MapObjectsController & '#Url.Action("mapContact", 'MapObjects")'; But to no avail
$.ajax({
url: url,
type: 'POST',
contentType: 'application/json; charset=utf-8',
cache: false,
success: function (result) {
alert("success");
}
});
});
And in my controller:
namespace myName.Controllers
{
public class MapObjectsController : Controller
{
public IActionResult Index()
{
return View();
}
[HttpPost]
public JsonResult mapContact()
{
Account account = new Account();
return Json(account);
}
}
}
The 'account' is just a normal model (obvs empty in this case). All I receive is a 404 error in the console though.
As mentioned this is the 1st time I've .net Core (this is code I've written loads of times in 'normal' MVC projects) so it's possible that I'm missing something really obvious.
Thanks,
C
The first, try to call the #Url.Action() explicitly in the Ajax call :
$("#contactMap").click(function (e) {
e.preventDefault();
$.ajax({
url: '#Url.Action("mapContact", "MapObjects")',
type: 'POST',
contentType: 'application/json; charset=utf-8',
cache: false,
success: function (result) {
alert("success");
}
});
});
The second, check your routing rules.

Passing multiple ajax parameters to mvc controller

I can pass a serialized form to a mvc controller no problems with code below and all is populated
$("#btnExecuteJob").on("click", function (e) {
var frmForm1 = $("#form1").serialize();
$.ajax({
cache: false,
url: "/mvcController/executeJob",
dataType: 'json',
type: 'POST',
data: frmForm1,
success: function (resp) {},
error: function (resp) {}
});
});
Controller
[HttpPost]
public ActionResult executeJob(runDetails jobDetails)
{
//
// Process
//
return View();
}
I have added a second form to my view and now want to pass both to the controller so I tried
$("#btnExecuteJob").on("click", function (e) {
var frmForm1 = $("#form1").serialize();
var frmForm2 = $("#form2").serialize();
$.ajax({
cache: false,
url: "/jobScheduler/executeJob",
dataType: 'json',
type: 'POST',
data: {
jobDetails: frmForm1,
jobParameters: frmForm2
},
success: function (resp) {},
error: function (resp) {}
});
});
Controller
public ActionResult executeJob(runDetails jobDetails, runParams jobParameters)
{
//
// Process
//
return View();
}
and neither jobDetails or jobParams is populated, both work individually as first example
and all details are populated, any help much appreciated,
both forms really need to be separate in the controller

Use Ajax and JsonResult in ASP.NET MVC 3

I need to get string array or list with ajax and Action, this is my Implementation:
This is my html Dom of view of Index action in AccessMenuController:
<div class="RoleAccess">
<select name="RoleDropDown">
<option value="0">Select Role</option>
<option value="61AD3FD9-C080-4BB1-8012-2A25309B0AAF">AdminRole</option>
<option value="8A330699-57E1-4FDB-8C8E-99FFDE299AC5">Role2</option>
<option value="004E39C2-4FFC-4353-A06E-30AC887619EF">Role3</option>
</select>
</div>
My Controller:
namespace MyProject.Areas.GlobalAccess.Controllers {
public class AccessMenuController : Controller {
public ActionResult Index() { return View();}
[HttpPost]
public JsonResult RoleDropDownChanged(string roleId) {
Guid RoleId = new Guid(roleId);
//Some implement
List<string> actions = new List<string>();
for(int i = 0; i <= 10; i++)
actions.Add(i.ToString());
return Json(actions.ToArray(), JsonRequestBehavior.AllowGet);
}
}
}
and the script:
$(document).ready(function () {
//Handle Checks of Actions by RoleName Changed
$('div.RoleAccess select').change(function () {
RoleChangeHandler();
});
function RoleChangeHandler() {
$.ajax({
url: '#Url.Action("RoleDropDownChanged")',
type: 'POST',
data: { 'roleId': '61AD3FD9-C080-4BB1-8012-2A25309B0AAF' },
dataType: 'json',
processData: false,
contentType: 'application/json; charset=utf-8',
success: function (data) { SuccessRoleChangeHandler(data); },
error: OnFailRoleChangeHandler
});
return false;
}
function SuccessRoleChangeHandler(data) {
alert("in success role change");
}
function OnFailRoleChangeHandler(result) {
alert('in OnFailRoleChangeHandler');
}
And the problem is with all change of dropdown just Onfail function run and alert me "in OnFailRoleChangeHandler", also I check the RoleDropDownChanged Action with breakpoint and that never run, where is the problem?
UPDATE
when I load the page by chrome there is an error in console window:
http://MyProject/GlobalAccess/AccessMenu/#Url.Action(%22RoleDropDownChanged%22) 404 (Not Found) jquery-1.7.1.js:8102
Remove this setting:
contentType: 'application/json; charset=utf-8',
You are not sending any JSON to the server.
If you want to keep this setting then make sure that you are sending a valid JSON to your server:
data: JSON.stringify({ 'roleId': '61AD3FD9-C080-4BB1-8012-2A25309B0AAF' })
So:
$.ajax({
url: '#Url.Action("RoleDropDownChanged")',
type: 'POST',
data: { 'roleId': '61AD3FD9-C080-4BB1-8012-2A25309B0AAF' },
success: SuccessRoleChangeHandler,
error: OnFailRoleChangeHandler
});
should work (at least it does for me) with the following action:
[HttpPost]
public ActionResult RoleDropDownChanged(Guid roleId)
{
var actions = Enumerable.Range(1, 10).Select(x => x.ToString()).ToList();
return Json(actions);
}
UPDATE:
According to your comments it looks like you are trying to use server side helpers in a separate javascript which is not possible. Here's what I would suggest you. Start by providing the url when generating your dropdown:
<div class="RoleAccess">
#Html.DropDownListFor(
x => x.RoleDropDown,
Model.Roles,
"-- Select role --",
new {
data_url = Url.Action("RoleDropDownChanged")
}
)
</div>
and then in your separate javascript file:
$(document).ready(function() {
$('div.RoleAccess select').change(function () {
var url = $(this).data('url');
$.ajax({
url: url,
type: 'POST',
data: { 'roleId': '61AD3FD9-C080-4BB1-8012-2A25309B0AAF' },
success: function(result) {
alert('success');
},
error: function() {
alert('error');
}
});
});
});
and then of course you could replace the hardcoded roleId with the currently selected value:
data: { 'roleId': $(this).val() }
Move your $(document).ready function to your View like this:
<script type="text/javascript">
$(document).ready(function () {
//Handle Checks of Actions by RoleName Changed
$('div.RoleAccess select').change(function () {
RoleChangeHandler('#Url.Action("RoleDropDownChanged")');
});
});
</script>
Then in your JS file add url parameter to your function and change ajax call:
function RoleChangeHandler(pageUrl) {
$.ajax({
url: pageUrl,
type: 'POST',
data: { 'roleId': '61AD3FD9-C080-4BB1-8012-2A25309B0AAF' },
dataType: 'json',
processData: false,
contentType: 'application/json; charset=utf-8',
success: function (data) { SuccessRoleChangeHandler(data); },
error: OnFailRoleChangeHandler
});
return false;
}
This should work as you expected.
If your script resides in a .JS file then this is not going to work as it'll be treated as plain text. You can either move entire script to the view or you can re-factor script so that majority of the script remains in the .JS and you then pass relevant values from the view.

Ajax Call not working - is the call right

I am trying to send an ajax call with json array
the call function is
if(objHasValue) {
alert(JSON.stringify(objArray));
alert("before ajax call");
$.ajax({
type: 'POST',
url: 'http://www.web2222.net/Test/test.php',
dataType: 'json',
data: { json: JSON.stringify(objArray) },
success: function(data) {
alert('did it-'+data);
return false;
},
error: function(data){
alert('failure'+data.json);
}
});
}
return false;
somehow it doesn't work
Do I have any mistake there?
Thanks
i am not sure if this is the problem but try something like :
data: { "json": JSON.stringify(objArray) }

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");
