Question

我有一个对象，我正在使用ng-repeat，但需要以可排序的格式显示项目如果对于多个项目的总值相同，则应该对总值进行排序，如果p1与p2相同，则基于p1值进行排序，如果p2也相同，那么p3.i已经基于总数排序了对象值，但优先考虑如何基于多个对象属性进行排序？

我已经根据价值和关键进行了排序，但在这种复杂的情况下需要帮助

   {    "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"
        }

    }

Answer 1

您可以先创建一个数组，然后使用Array#sort()和带有所需排序层次结构的回调对其进行排序。

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);

您无法对对象进行排序，但可以使用Object.keys()创建对象键数组并对其进行排序

var obj = {"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"}}

var sort = Object.keys(obj).sort(function(a, b) {
  return obj[b].total - obj[a].total || obj[b].p1 - obj[a].p1 || obj[b].p2 - obj[a].p2 || obj[b].p3 - obj[a].p3;
})

console.log(sort)

然后，您可以使用该排序的键数组按排序顺序返回对象值

var obj = {"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"}}

var sort = Object.keys(obj).sort(function(a, b) {
  return obj[b].total - obj[a].total || obj[b].p1 - obj[a].p1 || obj[b].p2 - obj[a].p2 || obj[b].p3 - obj[a].p3;
})

sort.forEach(function(e) {console.log(obj[e]) });
