与ASP.NET网站通信时，jQuery AJAX返回错误0

Question

I'm learning ASP.NET and I wanted to whip up a simple site that uses ajax to just get a string back from the server.

When I run the ajax request it displays An error occured: 0 error

Here's what I have so far

The controller for the index page with the ajax request on it:

public ActionResult Index()
{
    return View();
}

The Controller for the ajax request:

public class AjaxTestController : Controller
{
    public ActionResult AjaxAction()
    {
        return Content(@"Success!");
    }
}

the jQuery from the index page:

$( "#submit_button" ).click(function( event ) 
{
    $.ajax({
        type: "POST",
        url: "http://localhost:49636/AjaxTest/AjaxAction",
        data: "{}",
        success:function(result){
            alert( "Response: " + result );
        },
        error:function(xhr){
            alert("An error occured: " + xhr.status + " " + xhr.statusText);
    }});
});

When I go to http://localhost:49636/AjaxTest/AjaxAction in my browser it displays Success! as expected.

Other questions about error 0 say it could have something to do with trying to access a different domain, but I'm not sure that applies here. Any ideas?

Thanks

Answer 1

您是否尝试过将类型更改为“ GET”而不是“ POST”？

Answer 2

您还可以将[HttpPost] AjaxAction添加到AjaxAction 。
