如何在Javascript/Jquery中使用json中的'Key'获取'Value'

Question

我有以下Json字符串.我希望使用'Key'得到'Value',就像这样

给'BtchGotAdjust'返回'Batch Got Adjusted';

var jsonstring=
[{"Key":"BtchGotAdjust","Value":"Batch Got Adjusted"},{"Key":"UnitToUnit","Value":"Unit To Unit"},]

Answer 1

哇...看起来有点难!好像你需要稍微操纵一下.我们可以用这种方式创建一个新对象,而不是函数:

var jsonstring =
    [{"Key":"BtchGotAdjust","Value":"Batch Got Adjusted"},{"Key":"UnitToUnit","Value":"Unit To Unit"},];
     var finalJSON = {};
     for (var i in jsonstring)
         finalJSON[jsonstring[i]["Key"]] = jsonstring[i]["Value"];

您可以使用它:

finalJSON["BtchGotAdjust"]; // Batch Got Adjusted
