AngularJs的UI组件ui-Bootstrap分享（二）——Collapse

Collapse折叠控件使用uib-collapse指令

             }

             $scope.exping = function () {

                 console.log("expanding");

             }

         });

     <div ng-controller="CollapseDemoCtrl">

         <button type="button" class="btn btn-default" ng-click="isCollapsed = !isCollapsed">Toggle collapse</button>

         <div uib-collapse="isCollapsed" collapsed="coled()" collapsing="coling()" expanded="exped()" expanding="exping()">

折叠控件可以使用的属性有：

(1) uib-collapse. 默认为false.表示是否收起控件

(2) collapsed.组件收起之后调用的函数.

(3) collapsing.组件收起前调用的函数.如果返回一个拒绝的promise,收起动作将被取消

(4) expanded.组件展开之后调用的函数.

(5) expanding.组件展开前调用的函数.如果返回一个拒绝的promise,展开动作将被取消

在AngularJS中使用Promise，要使用AngularJS的内置服务$q。下面这个例子返回了一个拒绝的promise：

     <script>

         angular.module('ui.bootstrap.demo', ['ui.bootstrap']).controller('CollapseDemoCtrl', function ($scope, $q) {

             $scope.isCollapsed = false;

             $scope.coled = function () {

                 console.log("collapsed");

             }

             $scope.coling = function () {

                 console.log("collapsing");

                 var deferred = $q.defer();

                 var promise = deferred.promise;

                 promise.then(function (result) {

                     alert("Success: " + result);

                 }, function (error) {

                     alert("Fail: " + error);

                 });

                 deferred.reject("Can't Collapse");

                 return promise;

             }

             $scope.exped = function () {

                 console.log("expanded");

             }

             $scope.exping = function () {

                 console.log("expanding");

             }

         });

     </script>
