return JSON string from MVC controller
提问by stefan
I use the following code to send/receive an object to my mvc controller:
我使用以下代码向我的 mvc 控制器发送/接收对象：
$.ajax({
url: _createOrUpdateTimeRecord,
data: JSON.stringify(data),
type: "POST",
//dataType: "json",
contentType: "application/json; charset=utf-8",
beforeSend: function () {
$("#loading-overlay").show();
},
success: function (data2) {
try { // tried to parse it manually to see if anything changes.
data2 = JSON.parse(data2);
}
catch (err) {
}
},
error: function (xhr, ajaxOptions, thrownError) {
alert(thrownError + 'xhr error -- ' + xhr.status);
}
});
});
On my mvc controller I have my JSON object as string so I don't need the .NET JavascriptSerializer and JsonResult.
在我的 mvc 控制器上，我有我的 JSON 对象作为字符串，所以我不需要 .NET JavascriptSerializer 和 JsonResult。
My JSON string looks like:
我的 JSON 字符串如下所示：
data2 = "{title:'1111111',start:'2014-03-23T16:00:00.000',end:'2014-03-23T18:00:00.000',id:107,hdtid:1,color:'#c732bd',allDay:false,description:''}"
And I always get: "Invalid character"
我总是得到：“无效字符”
I already tried to return a string and parse the JSON manually on client side. Therefore I used ContentResult as return type but with no success
我已经尝试返回一个字符串并在客户端手动解析 JSON。因此我使用 ContentResult 作为返回类型但没有成功
public class JsonStringResult : ContentResult
{
public JsonStringResult(string json)
{
Content = json;
ContentType = "application/json";
}
}
What is the problem here? The JSON looks fine...
这里有什么问题？JSON 看起来不错...
Cheers, Stefan
干杯，斯蒂芬

Just Try it Json Conrtroller
试试吧 Json 控制器
public JsonResult fnname()
{
string variablename = "{title:'1111111',start:'2014-03-23T16:00:00.000',end:'2014-03-23T18:00:00.000',id:107,hdtid:1,color:'#c732bd',allDay:false,description:''}";
return Json(variablename , JsonRequestBehavior.AllowGet);
}
Jquery json passing
jquery json 传递
$(document).ready(function() {
$.post("/controllername/fnname", { }, function (result) {
alert(result);
}, "json");
});

Your data2 is INVALIDJSON string. It should be:
您的 data2 是无效的JSON 字符串。它应该是：
data2 = "{\"title\":\"1111111\",\"start\":\"2014-03-23T16:00:00.000\",\"end\":\"2014-03-23T18:00:00.000\",\"id\":107,\"hdtid\":1,\"color\":\"#c732bd\",\"allDay\":false,\"description\":\"\"}"
Read JSON standard here http://json.org
在这里阅读 JSON 标准http://json.org
JSON is more strict than plain javascript, key has to be wrapped in double quote, and string has to be wrapped in double quote too, single quote is invalid.
JSON 比普通的 javascript 更严格，key 必须用双引号括起来，字符串也必须用双引号括起来，单引号无效。
Douglas Crockford designed strict format of JSON for reasons. http://www.yuiblog.com/blog/2009/08/11/video-crockford-json/
