json升序？

格式：

var cases = [{"id":"http://wb.gd.labscare.com/lab/#/public/1011462120167579094","t_code":"B01-R10QY04-001","t_code2":"B01-R10QY04-018","id2":"http://jthg.gd.labscare.com/lab/#/public/1011463417778803040"},{"id":"http://wb.gd.labscare.com/lab/#/public/1011467465864884014","t_code":"B01-R10QY04-005","t_code2":"","id2":""}]

var objData = []

function t_tamiStorage() {
    return {
        id: "",
        t_code: "",
        t_code2: "",
        id2: ""
    }
}

代码

    //最终结果结构体
var idx = 0;
for (var i = 0; i < cases.length; i++) {
    var item = cases[i]
    if(i%2===0){
        var showdata = t_tamiStorage();
        objData.push(showdata);
        showdata.t_code = item['1066989928805654067'];
        showdata.id = getUrl + item.id;
        idx++;
    }else{
        objData[idx-1]['t_code2'] = item['1066989928805654067'];
        objData[idx-1]['id2'] =  getUrl + item.id;
    }

}
objData.sort((a, b) => {
    // 比较t_code
    const tCodeComparison = a.t_code.localeCompare(b.t_code);
    if (tCodeComparison !== 0) return tCodeComparison;
    return a.t_code2.localeCompare(b.t_code2);
  });

console.log(objData)

打印

t_code，t_code2是标识符，

请问大佬们这个要排序（升序）呢
