{
    "JsonResult": {
        "List": [{
            "Subject": "Something",
            "Type": 0,
            "TypeDescription": "Referral"
        }],
     }
}

这是我在点击服务时得到的示例 json 响应，之后我有一个带有选项的按钮，例如Subject, Type and TypeDescription.

如何根据我发送的参数对 Json 响应进行排序。

function sortItems(jsonResponse,paramater){
          var sorted =  jsonResponse.List.sort( function(a, b) {
          var nameA = a.paramater.toLowerCase(),
          nameB = b.paramater.toLowerCase();
          return nameA.localeCompare(nameB);
}

这是我正在使用的排序功能，但它不起作用。我已经有了 JSON 响应，我需要在运行时根据我发送的参数进行排序。

function sortItems(jsonResponse, paramater) {
      var sorted =  jsonResponse.JsonResult.List.sort(function(a, b) {
          var nameA = a[paramater].toLowerCase(), //take note, []
          nameB = b[paramater].toLowerCase(); //same here
          return nameA.localeCompare(nameB);
      });
}

第二个参数“参数”是一个字符串，表示要查找的键，而不是直接的字段访问器语句。因此无法使用点运算符从 json 访问它。

另外，请注意：它应该是：

jsonResponse.JsonResult.List.sort

不久前，我也想做同样的事情：请参阅此处了解一些技巧：
