I have a jquery ajax script like following
$.ajax({
type: "POST",
url: "Main/receive", // the method we are calling
contentType: "application/json; charset=utf-8",
data: JSON.stringify({ 'p':$("#txtname").val() }),
dataType: "json",
success: function (result) {
alert('Yay! It worked!');
// Or if you are returning something
},
error: function (result) {
alert('Oh no zzzz:('+result.responseText);
}
});
And I am calling to Controller action method. The data is sending to the controller's action method and I am also receiving data from the controller. But the data that I am receiving is inside the error function of jquery ajax.
I want it to be inside the success function.
Why my success function is not getting called.
Following is my controller's action method,
[HttpPost]
public string receive(string p)
{
ViewBag.name = p;
return p;
}
The reason for the error is that you have specified that the returned data type be json (in the line dataType: "json",
) but you method returns text. You have 2 options.
return Json(p);
dataType: "text",
or just omit it However you can improve your script as noted below
$.ajax({
type: "POST",
url: '@Url.Action("receive", "Main")', // don't hardcode url's
data: { p: $("#txtname").val() }, // no need to stringify (delete the contentType: option)
dataType: "json",
success: function (result) {
alert('Yay! It worked!');
},
error: function (result) {
alert('Oh no zzzz:('+result.responseText);
}
});
or even simpler
$.post('@Url.Action("receive", "Main")', { p: $("#txtname").val() }, function(result) {
alert('Yay! It worked!');
}).fail(function(result) {
alert('Oh no zzzz:('+result.responseText);
});
Notes: You should always use @Url.Action()
to generate the correct urls, and it is not necessary in this case to stringify the data (but you need to remove the contentType:
line so it used the default application/x-www-form-urlencoded; charset=UTF-8
)
In addition, this is not strictly a POST (your not changing data on the server - but I assume this is just for testing). And there is no point in the line ViewBag.name = p;
- it does nothing in your context, and as soon as you return from the method, ViewBag
is lost anyway.
try to change your controller code as follows
[HttpPost]
public ActionResult List(string p)
{
ViewBag.name = p;
return Json(ViewBag);
}
Your controller method should look like this:
[HttpPost]
public ActionResult receive(string p)
{
return Json(p);
}
