轻松Angularjs实现表格按指定列排序

　　angular表格点击序号进行升序，再次点击进行降序排序，在输入框输入信息，出现相对应数据的那一行。

　html:

<input type="text" ng-model="search"/>
<table border="1" cellpadding="0" cellspacing="1" width="400px">
    <tr>
        <th ng-click="click()">编号</th>
        <th ng-click="click1()">姓名</th>
        <th ng-click="click2()">年龄</th>
    </tr>
    <tr ng-repeat="item in data|orderBy:a+b+c|filter:search">
        <td>{{item.number}}</td>
        <td>{{item.name}}</td>
        <td>{{item.age}}</td>
    </tr>
</table>

js:

var app=angular.module('mk',[]);
        app.controller('test',function($scope,$http){
                $http.get('json.json').success(function(data){
                    $scope.data=data.nr
                });
            $scope.a='number';
            $scope.b='name';
            $scope.c='age';
            $scope.click=function(){
                if($scope.a=='number'){
                    $scope.a='-number';
                    $scope.b='';
                    $scope.c='';
                }else{
                    $scope.a='number';
                    $scope.b='';
                    $scope.c='';
                }
            };
            $scope.click1=function(){
                if($scope.b=='name'){
                    $scope.a='';
                    $scope.b='-name';
                    $scope.c='';
                }else{
                    $scope.a='';
                    $scope.b='name';
                    $scope.c='';
                }
            };
            $scope.click2=function(){
                if($scope.c=='age'){
                    $scope.a='';
                    $scope.b='';
                    $scope.c='-age';
                }else{
                    $scope.a='';
                    $scope.b='';
                    $scope.c='age';
                }
            }
        })

此方法还需引用json文件：

{
  "nr":[
    {"number":34,"name":"Angular","age":24},
    {"number":24,"name":"Blue","age":25},
    {"number":14,"name":"Fertn","age":23},
    {"number":43,"name":"Onfer","age":26},
    {"number":36,"name":"Wang","age":21},
    {"number":31,"name":"Linla","age":30},
    {"number":4,"name":"San","age":28},
    {"number":6,"name":"Ring","age":22},
    {"number":76,"name":"Cone","age":31},
    {"number":32,"name":"Perter","age":32},
    {"number":32,"name":"Nert","age":27},
    {"number":15,"name":"Ding","age":29}
  ]
}

我是用过滤器 orderBy:'id':a+b+c来控制排序是升序还是降序，在点击时通过判断他们的来实现我们想要的效果。

你们还有什么简单方法么，拿出来分享一下吧！
