使用Angularjs 1.3.4。

我有一个html表,它是从一个web api填充的,在那里我发出一个http请求来获取数据并填充我的html表。我的json示例如下:

{
    id: 1,
    firstName: "John",
    lastName: "Rein",
    status: 'available'
},
{
    id: 2,
    firstName: "David",
    lastName: "Gumry",
     status: 'not available'
}

现在我在表下面有一个下拉列表,我正在使用ui-select。我想根据json中的状态填充这个下拉列表。例如,在上面的json中,我有两个可用和不可用的状态。我希望我的下拉列表具有这些值。填充下拉列表后,我想根据所选的下拉值筛选表。我的下拉列表是:

  <ui-select tagging ng-model="selected" theme="bootstrap">
    <ui-select-match placeholder="Pick one...">{{$select.selected.value}}</ui-select-match>
    <ui-select-choices repeat="val in values | filter: $select.search track by val.value">
        <div ng-bind="val.value | highlight: $select.search"></div>
    </ui-select-choices>        
</ui-select>

我在以下位置创建了jsfiddle: https://jsfiddle.net/aman1981/wfL1374x/

我不知道如何将json的结果绑定到ddl并过滤表。

你有一些问题需要处理,包括冗余使用的天然气应用程序和天然气控制器。而且,似乎ui-select最适合使用controllera语法,而controllera语法通常是首选方法。

在这些更改和其他更改(太多无法列出)之后,下面是工作代码:

angular.module('myApp', ['ui.select'])

  .controller("PeopleCtrl", function($http) {

    var vm = this;

    vm.people = [];
    vm.isLoaded = false;
    vm.values = [];

    vm.loadPeople = function() {
      // *** I had to comment this out as it is not allowed in the SO Code Snippet but is fine for your code
      //$http({
      //  method: 'POST',
      //  url: '/echo/json/',
      //  data: mockDataForThisTest

      //}).then(function(response, status) {
      //  console.log(response.data);
      //  vm.people = response.data;
      //});
      vm.people = [{
          id: 1,
          firstName: "John",
          lastName: "Rein",
          status: 'available'
        },
        {
          id: 2,
          firstName: "David",
          lastName: "Gumry",
          status: 'not available'
        }
      ];

      vm.values = [...new Set(vm.people.map(obj => ({
        value: obj.status
      })))];
    };

    vm.selected = {
      key: null,
      value: null
    };

    var mockDataForThisTest = "json=" + encodeURI(JSON.stringify([{
        id: 1,
        firstName: "John",
        lastName: "Rein",
        status: 'available'
      },
      {
        id: 2,
        firstName: "David",
        lastName: "Gumry",
        status: 'not available'
      }
    ]));
  })
