Question

我需要使用此对象中的select选项在下拉列表中显示类别值：

[{
    "_id": "57b4508923a10cd83c79a301",
    "created_by": "1",
    "category": "Criminal law",
    "__v": 0,
    "delete_status": "0",
    "active_status": "1",
    "modified_date": "1471434889599",
    "created_date": "1471434889599"
}, {
    "_id": "57b466b34f94fc982a0d926d",
    "created_by": "1",
    "category": "Business Law",
    "__v": 0,
    "delete_status": "0",
    "active_status": "1",
    "modified_date": "1471440563159",
    "created_date": "1471440563158"
}, {
    "_id": "57c6be3ae74cdc1d6a9b2224",
    "created_by": "1",
    "category": "Corporate Law",
    "__v": 0,
    "delete_status": "0",
    "active_status": "1",
    "modified_date": "1472642618768",
    "created_date": "1472642618768"
}]

我使用下面的代码，但未定义：

<select ng-model="category" ng-options="users.id as users.category for item in items"></select>

任何人都可以帮助我吗？

Answer 1

试试这个

var app = angular.module('app', []).controller('countryCtrl', ['$scope',
  function($scope) {
    $scope.records = [{
      "_id": "57b4508923a10cd83c79a301",
      "created_by": "1",
      "category": "Criminal law",
      "__v": 0,
      "delete_status": "0",
      "active_status": "1",
      "modified_date": "1471434889599",
      "created_date": "1471434889599"
    }, {
      "_id": "57b466b34f94fc982a0d926d",
      "created_by": "1",
      "category": "Business Law",
      "__v": 0,
      "delete_status": "0",
      "active_status": "1",
      "modified_date": "1471440563159",
      "created_date": "1471440563158"
    }, {
      "_id": "57c6be3ae74cdc1d6a9b2224",
      "created_by": "1",
      "category": "Corporate Law",
      "__v": 0,
      "delete_status": "0",
      "active_status": "1",
      "modified_date": "1472642618768",
      "created_date": "1472642618768"
    }];
  }
])

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="countryCtrl">
  <select ng-init="text._id = records[0]._id" ng-model="text" ng-options="record.category for record in records track by record._id">
  </select>
</div>

Answer 2

<select ng-model="category" ng-options="item.id as item.category for item in items"></select>

只需在模板中更新（y）：）

使用选择选项和angularjs中的对象
