【问题描述】：

我的 JSON 对象如下：

$scope.data = [{
id: "146",
name: "Sachin",
dataList: [{maunalEntityName: "Temperature", quantity: 15},
          {maunalEntityName1: "Air", quantity: 25}] },
          {
id: "147",
name: "Rahul",
dataList: [{maunalEntityName: "Water", quantity: 27},
          {maunalEntityName1: "Temperature", quantity: 14}] }
          {
id: "148",
name: "Sourav",
dataList: [{maunalEntityName: "Air", quantity: 20,
          {maunalEntityName1: "Water", quantity: 8}] }
];

我想在angularJS中根据dataList中的数量进行排序。

【问题讨论】：

你试过使用 orderBy 吗？
您也可以使用过滤器。
Plunker链接如下：plnkr.co/edit/UX7pVhBlQrFK874E86Af?p=preview
self.records: [{ "Reg_code": 10001025, "Name": "Chandan Kumar Penta", "staticColumn": { "Check": "Check1", "HHHHH": "" } }, { "Reg_code": 10001290, "Name": "test_B2", "staticColumn": { "Check": "Check2", "HHHHH": "" } }, { "Reg_code": 10001028, "Name": "Ronny Lewis", "staticColumn": { "Check": "Check3", "HHHHH": "" } } ] 这是我的 json 对象。我想在检查的基础上进行排序。请帮忙

【解决方案1】：

If you want to sort items in $scope.data based on the sum of all quantity in the dataList array:

$scope.data = $scope.data.sort(function(it1, it2) {

var it1QuantitySum = 0;
var it2QuantitySum = 0;

it1.dataList.forEach(function(data) {
	it1QuantitySum = it1QuantitySum + data.quantity;
});	

it2.dataList.forEach(function(data) {
	it2QuantitySum = it2QuantitySum + data.quantity;
});	
return it1QuantitySum < it2QuantitySum;
});
