javascript - 根据优先级对基于多个属性的javascript对象进行排序

Question

我有一个对象，我正在使用 ng-repeat 但需要以可排序格式显示项目如果多个项目的总值相同，则应根据总值进行排序，如果 p1 与 p2 相同，则应根据 p1 值进行排序，如果 p2 也相同，则 p3.i 已经根据总值对对象进行排序值但停留在优先级如何基于多个对象属性进行排序？。

我已经完成了基于值和键的排序，但在这种复杂情况下需要帮助

   {    "QVC":{
            "p1":0,
            "p2":12,
            "p3":12,
            "total":24,
            "org":"QVC"
        },
        "TURNER & TOWNSEND":{
            "p1":12,
            "p2":12,
            "p3":0,
            "total":24,
            "org":"TURNER & TOWNSEND"
        },
        "EDF ENERGY":{
            "p1":12,
            "p2":0,
            "p3":12,
            "total":24,
            "org":"EDF ENERGY"
        },
        "TOWERS WATSON":{
            "p1":6,
            "p2":0,
            "p3":6,
            "total":12,
            "org":"TOWERS WATSON"
        },
        "VODAFONE UK LTD":{
            "p1":0,
            "p2":1,
            "p3":0,
            "total":1,
            "org":"VODAFONE UK LTD"
        },
        "DENPLAN LTD":{
            "p1":1,
            "p2":0,
            "p3":0,
            "total":1,
            "org":"DENPLAN LTD"
        }

    }

可以先做一个数组，然后用Array#sort()排序以及具有所需排序层次结构的回调。

var object = { "QVC": { "p1": 0, "p2": 12, "p3": 12, "total": 24, "org": "QVC" }, "TURNER & TOWNSEND": { "p1": 12, "p2": 12, "p3": 0, "total": 24, "org": "TURNER & TOWNSEND" }, "EDF ENERGY": { "p1": 12, "p2": 0, "p3": 12, "total": 24, "org": "EDF ENERGY" }, "TOWERS WATSON": { "p1": 6, "p2": 0, "p3": 6, "total": 12, "org": "TOWERS WATSON" }, "VODAFONE UK LTD": { "p1": 0, "p2": 1, "p3": 0, "total": 1, "org": "VODAFONE UK LTD" }, "DENPLAN LTD": { "p1": 1, "p2": 0, "p3": 0, "total": 1, "org": "DENPLAN LTD" } },
    array = Object.keys(object).map(function (k) { return object[k]; });

array.sort(function (a, b) {
    return a.total - b.total || a.p1 - b.p1 || a.p2 - b.p2 || a.p3 - b.p3;
});

console.log(array);
