Collapse折叠控件使用uib-collapse指令

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：

 1     <script>
 2         angular.module(\'ui.bootstrap.demo\', [\'ui.bootstrap\']).controller(\'CollapseDemoCtrl\', function ($scope, $q) {
 3             $scope.isCollapsed = false;
 4 
 5             $scope.coled = function () {
 6                 console.log("collapsed");
 7             }
 8             $scope.coling = function () {
 9                 console.log("collapsing");
10 
11                 var deferred = $q.defer();
12                 var promise = deferred.promise;
13 
14                 promise.then(function (result) {
15                     alert("Success: " + result);
16                 }, function (error) {
17                     alert("Fail: " + error);
18                 });
19 
20                 deferred.reject("Can\'t Collapse");
21                 return promise;
22             }
23             $scope.exped = function () {
24                 console.log("expanded");
25             }
26             $scope.exping = function () {
27                 console.log("expanding");
28             }
29         });
30     </script>
