爲什麼orderBy在angularjs中不能在ngrepeat中工作？

Question

我正在嘗試使用orderBy在ng-repeat使用角度js.but但它不能排序我的列表。有我的代碼？

如何整理我的代碼

https://jsfiddle.net/7MhLd/1921/

var myApp = angular.module('myApp', []); 

function MyCtrl($scope) { 
    $scope.lines = { 
     "a" : {name:"bb"}, 
     "aa": {name: 'aa'}, 
     "zz": {name:"zz"}, 
     "oo": {name: 'oo'}, 
     "kk": {name:"k"}, 
     "j" : {name: "a"}, 
     "n" : {name:"n"}, 
     "c" : {name: "c"} 
    } 
} 

Answer 1

你必須把你的對象轉換成數組，以得到它的工作

<div ng-controller="MyCtrl"> 
    <div ng-repeat="line in lines | orderBy:'name'"> 
    <div class="preview">{{line.name}} {{$index}}</div> 
    </div> 
</div> 

和控制器

var myApp = angular.module('myApp', []); 

function MyCtrl($scope) { 
    $scope.lines = [ 
     {name:"bb"}, 
    {name: 'aa'}, 
    {name:"zz"}, 
    {name: 'oo'}, 
    {name:"k"}, 
    {name: "a"}, 
    {name:"n"}, 
    {name: "c"} 
]; 
}
