In my AJAX call, I want to return a string value back to the calling page.
Should I use ActionResult or just return a string?
This question is related to
asp.net-mvc
ajax
actionresult
public ActionResult GetAjaxValue()
{
return Content("string value");
}
public JsonResult GetAjaxValue()
{
return Json("string value", JsonRequetBehaviour.Allowget);
}
You can also just return string if you know that's the only thing the method will ever return. For example:
public string MyActionName() {
return "Hi there!";
}
As of 2020, using ContentResult is still the right approach as proposed above, but the usage is as follows:
return new System.Web.Mvc.ContentResult
{
Content = "Hi there! ?",
ContentType = "text/plain; charset=utf-8"
}
There Are 2 ways to return a string from the controller to the view:
First
You could return only the string, but it will not be included in your .cshtml file. it will be just a string appearing in your browser.
Second
You could return a string as the Model object of View Result.
Here is the code sample to do this:
public class HomeController : Controller
{
// GET: Home
// this will return just a string, not html
public string index()
{
return "URL to show";
}
public ViewResult AutoProperty()
{
string s = "this is a string ";
// name of view , object you will pass
return View("Result", s);
}
}
In the view file to run AutoProperty, It will redirect you to the Result view and will send s
code to the view
<!--this will make this file accept string as it's model-->
@model string
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Result</title>
</head>
<body>
<!--this will represent the string -->
@Model
</body>
</html>
I run this at http://localhost:60227/Home/AutoProperty.
