AngularJS使用selectize和ng repeat设置multi select下拉列表的值

multiple-select selectize.js angularjs html javascript

但我用的是 选择插件
https://selectize.github.io/selectize.js/
对于下拉多选,我不知道如何填充已经选择的值。?

<div ng-repeat="item in items">

<select  
multiple 
class="selectSkill"
ng-model="item.storedArray"
ng-options="opt.skillId as opt.skillName for opt in skills"
></select>

</div>

我的委托人:

$scope.$selectSkill= $('.selectSkill').selectize({
    valueField: 'skillId',
    labelField: 'skillName',
    searchField: 'skillName',
    maxItems: 5,
    placeholder:"Select Skill",
    options: $scope.skills,
    create: false,
    sortField: {
        field: 'skillName',
        direction: 'asc'
    }
});
$scope.selectizeControlSkills = $scope.$selectSkill[0].selectize;

selectSkill ).

如果没有填充,则正常加载可以工作,但我尝试使用selectize动态设置值。

谢谢你的帮助。

我的演示数据:

**$scope.skills**

**item.storedArray**

发布我创建的示例作为答案,因为它似乎有助于OP。

ng-model 和 ng-options 因为如果应用到同一个应用程序中,它们在功能上相互冲突 select

如果您想使用Selectize,最好创建一个包装器(即一个指令,如我的示例中所示)来提供 选择 需要它的元素。

scope.$apply()

angular
  .module('app', [])
  .controller('ctrl', function ($scope) {
    $scope.items = [
      { storedArray: ['078...'] },
      { storedArray: [] },
      { storedArray: ['0cc...'] },
    ];
    $scope.skills = [
      { skillId: '078...', skillName: 'Java' },
      { skillId: '0cc...', skillName: 'Cisco UCS' },
    ];
    $scope.itemSelectizeOptions = $scope.items.map(function (item) {
      return {
        valueField: 'skillId',
        labelField: 'skillName',
        options: $scope.skills,
        items: item.storedArray,
        onChange: function (newItems) {
          item.storedArray = newItems;
          // `$apply()` needed because change occurs outside of AngularJS's knowledge
          $scope.$apply();
        }
      };
    })
  })
  .directive('selectize', function () {
    return {
      scope: {
        selectize: '<',
      },
      link: function (scope, el) {
        var selectize = $(el).selectize(scope.selectize);
      },
    };
  });
