javascript - JQuery:从json读取值

Question

我有以下代码:

var Configuration = {
    conf : {},
    buildConfig : function (){
    var configugration = {};

    configugration.supportedCountsInJSON = ["closedSRCount","resSRCount","openTAGCount","SECount"];
    return configugration;  
},

和一个像这样的变量:

var teamCountsJson = 
[   {
    "associateId" : "AA029693",
    "closedSRCount" : "10",
    "resSRCount" : "8",
    "openTAGCount" : "0",
    "SECount" : "7",
},
{
    "associateId" : "BB029693",
    "closedSRCount" : "4",
    "resSRCount" : "1",
    "openTAGCount" : "0",
    "SECount" : "1",
}]

当我尝试根据配置变量中的键读取上述 Json 中的值时，如下所示，我得到“未定义”:

calculateMinCounts: function(teamCountsJson){
    $.each(teamCountsJson, function(index){
        var minValues = [];
        var sKey ='';
        $.each(Configuration.conf.supportedCountsInJSON, function(id){
            minValues = [];
            sKey = Configuration.conf.supportedCountsInJSON[id]

            if(teamCountsJson[index].hasOwnProperty(sKey)){
                minValues.push(teamCountsJson[index].sKey);
                console.log('sKey='+sKey+', minValues='+JSON.stringify(teamCountsJson[index].sKey)); //Unable to read the value 'undefined'
            }
            else{
                //console.log('associateId does not exit!!'+Configuration.conf.supportedCountsInJSON[id]);
            }

        });

我知道

sKey = Configuration.conf.supportedCountsInJSON[id]

当我注销它们时，变量给了我以下键:

["closedSRCount","resSRCount","openTAGCount","SECount"];

但是，当我尝试读取上述代码中 Json 中每个键的值(例如，associateId)时，如下所示，我得到“未定义”并且无法读取这些值:

teamCountsJson[index].sKey

有什么想法吗？

请指教，

谢谢!

没有sKey属性，如果要使用包含属性名称的变量，则必须使用括号表示法

teamCountsJson[index][sKey]
