I want to call a controller method which returns a string value from view, for example suppose I have a controller method public string Username(string email). I want to call this method in view so that I can assign return Value i.e. User name to my label.
So I have two question :-
if you want to display it:
@{Html.RenderAction("Username", "ControllerName" , new {email="your email"});}
If you want to call it through ajax, use
'@Url.Action("Username", "ControllerName" , new {email="your email"})' as url in your ajax request
Use the below code , also add [HttpPost] attribute above controller action method
$.ajax({
// method: 'POST', <-- remove this
type: 'POST', // <-- add this
url: '@Url.Action("ActionName","ControllerName")',
dataType: 'json',
data: { id: 'Parameter' },
success: function (data, textStatus, jqXHR) {
//the data here is returned from your controller action method
console.log("success");
},
error: function () {
alert('error');
}
});
View side
@model String
<label>Model</label>
Controller Side
public ActionResult ReturnString()
{
var user=userName//Get user name
return View(user)
}
Take a look at AJAX. If you are using JQuery, this task can be done with the ajax function. In your case the javascript would look something like this:
$.ajax({
url: '@Url.Action("Username")',
data: { email: "[email protected]" },
success: function (result) {
$('#YourLabel').val(result);
}
});
