在controller中定义了点击函数——一个布尔值的取反，把返回的布尔值绑定在ng-show上，在click时运行函数,不能正常的显示隐藏，代码如下
`

    HTML:
   

      
    Financial Dashboard        
    

        Overview
        Organization Roster
        Customer Rollup                          
    
    
    
    Operational Dashboard
    

        Overview
        Organization Roster
        Customer Rollup                       
    
        
    
    Opportunity Tracker
    

        Overview
        Organization Roster
        Customer Rollup                          
    
                         
  

JS:

  .controller("siderbarCtrl",["$scope",function($scope){
$scope.Financial_show=false;
$scope.Operational_show=true;
$scope.Opportunity_show=false;
$scope.show=function(ele){
    
    return $scope.ele=!$scope.ele;
}}]);

下面的代码可以正常的显示隐藏：
