问题描述
我正在尝试使用jQuery.parseJSON来解析MVC3控制器操作的返回值.
I am trying to use jQuery.parseJSON to parse out the return value from an MVC3 controller action.
控制器:
[HttpPost]
public JsonResult LogOn(LogOnModel model, string returnUrl)
{
.. do stuff ..
if (errors.Count() < 0)
{
return Json(new object[] { true, model, errors });
}
return Json(new object[] { false, model, errors });
}
jQuery:
$.ajax({
url: form.attr('action'),
type: "POST",
dataType: "json",
data: form.serialize(),
success: function (data) {
var test = jQuery.parseJSON(data);
}
});
提琴手的杰森结果:
[false,{"UserName":"1","Password":"2","RememberMe":false},[{"Key":","Errors":[{"Exception":null ,"ErrorMessage": 提供的用户名或密码不正确.}]}]]
[false,{"UserName":"1","Password":"2","RememberMe":false},[{"Key":"","Errors":[{"Exception":null,"ErrorMessage":"The user name or password provided is incorrect."}]}]]
提琴手可以解析结果:
对jQuery.parseJSON的调用返回null.我的问题是,如何将json返回值解析为对象?
The call to jQuery.parseJSON is returning null.My questions is, how can I parse the json return value into an object?
谢谢!
推荐答案
您无需在成功处理程序中调用parseJSON,因为ajax
已经解析了JSON结果(因为您指定了dataType:'json'
)放入您的数组.
You don't need to call parseJSON in your success handler, because ajax
will have already parsed the JSON result (it does this automatically because you specified dataType:'json'
) into your array.
但是,我建议返回某种结果对象(无论您是使用C#创建实际的类还是使用匿名类型).
However, I'd recommend returning some sort of result object (whether you create an actual class in C# or use an anonymous type).
[HttpPost]
public JsonResult LogOn(LogOnModel model, string returnUrl)
{
.. do stuff ..
if (errors.Count() < 0)
{
return Json(new { success=true, model, errors });
}
return Json(new { success=false, model, errors });
}
和客户
$.ajax({
url: form.attr('action'),
type: "POST",
dataType: "json",
data: form.serialize(),
success: function (result) {
alert(result.success);
// also have result.model and result.errors
}
});
