由以上英文文档可以得知，若使用angularjs-dropdown-multiselect,首先需要在index.html中引入AngularJS >= 1.2, Lodash >= 2, Bootstrap >= 3.0，如下所示:
<script src="js/angularjs-dropdown-multiselect.js"></script>
<script src="js/lodash.min.js"></script>
并在app.js模块中添加依赖angularjs-dropdown-multiselect。如下所示:
var routerApp = angular.module('routerApp', ['ui.router', 'ngCookies', 'ngTable', 'angularjs-dropdown-multiselect', 'MedListModule']);
yh_set_dtl.html核心代码如下：
<div style="float:left">优 惠 类 型:</div>
<!-- Demo -->
<div ng-dropdown-multiselect=""
options="yhctlModelOptions"
selected-model="yhctlModel"
checkboxes="true">
</div>
controllers.js代码如下:
$scope.yhctlModel = [];
$scope.yhctlModelOptions = [
{id: 1, label: '限定用户'},
{id: 2, label: "限定商家"},
{id: 3, label: "限定使用次数"},
{id: 4, label: "限定药品"},
{id: 5, label: "与其它优惠共享"}];
