基于多个属性根据优先级排序javascript对象

我有一个对象，我使用的是ng-repeat，但需要显示可排序的合成项中的项目如果多个项目的总值与排序的总值相同，应对总值进行排序应该根据p1的值来完成，如果p1与p2相同，并且如果p2也相同，那么p3.i已经基于总值排序了对象，但是仍然优先考虑如何基于多个对象属性进行排序？基于多个属性根据优先级排序javascript对象

我已经做了基础的价值和重点排序上，但需要帮助的这种复杂的情况

{ "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" 
     } 

    }

请发表评论，如果你要投票做 –

，所以你需要用它应用数组排序？ –

是的，同样的数组我要去迭代 –

你可以让一个数组，然后再排序它Array#sort()与想要的那种层次的回调。

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);

这和我想要的完全一样 –

无法排序对象，但你可以用Object.keys()创建对象键的排列和排序它

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)

然后你就可以使用该键的排序数组的排序返回对象值订购

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]) });
