带有AngularJS中数据绑定内容的Tab指令

我正在尝试学习AngularJs，并且不确定创建通过数据绑定填充的选项卡式窗格的正确方法。

具体来说，我有三个HTML表，它们从3个不同的JSON文件中提取数据。显示此代码的代码很好用：

JS：

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

myApp.factory("Purchases", function(){
    var Purchases = {};
    Purchases.data = [
        {
            date: "20/05/2012",
            text: "Lorem ipsum dolor sit amet ipsum dolor"
        },
        {
            date: "20/05/2012",
            text: "Lorem ipsum dolor sit amet ipsum dolor"
        }
    ];
    return Purchases;
});

function PurchasesCtrl($scope, Purchases){
    $scope.purchases = Purchases;   
}


myApp.factory("SaleProducts", function(){
    var SaleProducts = {};
    SaleProducts.data = [
        {
            date: "20/05/2012",
            text: "Lorem ipsum dolor sit amet ipsum dolor"
        },
        {
            date: "20/05/2012",
            text: "Lorem ipsum dolor sit amet ipsum dolor"
        }
    ];
    return SaleProducts;
});

function SaleProductsCtrl($scope, SaleProducts){
    $scope.saleProducts = SaleProducts;   
}


myApp.factory("Sale30Days", function(){
    var Sale30Days = {};
    Sale30Days.data = [
        {
            date: "20/05/2012",
            text: "Lorem ipsum dolor sit amet ipsum dolor"
        },
        {
            date: "20/05/2012",
            text: "Lorem ipsum dolor sit amet ipsum dolor"
        }
    ];
    return Sale30Days;
});

function Sale30DaysCtrl($scope, Sale30Days){
    $scope.sale30Days = Sale30Days;   
}

HTML：

<div ng-app="myApp">
    <div class="tabs">
        <a href="" title="" class="tab selected" rel="tab1">Tab 1</a>
        <a href="" title="" class="tab" rel="tab2">Tab 2</a>
        <a href="" title="" class="tab" rel="tab3">Tab 3</a>
    </div>
    <div id="tab1" class="tabContent selected" ng-controller="PurchasesCtrl">
        <h2>Tab content 1:</h2>
        <table cellspacing="0">
            <tr class="first">
                <th class="first">Date</th>
                <th>Description</th>
            </tr>
            <tr ng-repeat="purchase in purchases.data" ng-class-odd="'odd'" ng-class-even="'even'" ng-class="{'last':$last}">
                <td class="first">{{purchase.date}}</td>
                <td>{{purchase.text}}</td>
            </tr>
        </table>
    </div>


    <div id="tab2" class="tabContent selected" ng-controller="SaleProductsCtrl">
        <h2>Tab content 2:</h2>                         
        <table cellspacing="0">
            <tr class="first">
                <th class="first">Date</th>
                <th>Description</th>
            </tr>
            <tr ng-repeat="saleProduct in saleProducts.data" ng-class-odd="'odd'" ng-class-even="'even'" ng-class="{'last':$last}">
                <td class="first">{{saleProduct.date}}</td>
                <td>{{saleProduct.text}}</td>
            </tr>
        </table>
    </div>


    <div id="tab3" class="tabContent selected" ng-controller="Sale30DaysCtrl">
        <h2>Tab content 3:</h2>
        <table cellspacing="0">
            <tr class="first">
                <th class="first">Date</th>
                <th>Description</th>
            </tr>
            <tr ng-repeat="sale30Day in sale30Days.data" ng-class-odd="'odd'" ng-class-even="'even'" ng-class="{'last':$last}">
                <td class="first">{{sale30Day.date}}</td>
                <td>{{sale30Day.text}}</td>
            </tr>
        </table>
    </div>
</div>

这里有一个小提琴：http://jsfiddle.net/9hZx5/2/。

现在，我不确定的部分是如何在页面加载时隐藏第二个和第三个选项卡，然后使用顶部的链接在选项卡式内容窗格之间切换。使用jQuery执行此操作（a）不起作用，（b）似乎非常错误，因为我想以'Angular'方式执行此操作。

我已经尝试按照这个小提琴http://jsfiddle.net/vojtajina/vM4FY/向链接和面板添加'ng：click'和'ng：show'，但我无法让它工作。我在此发现的教程/示例（例如Angular Bootstrap选项卡指令http://angular-ui.github.io/bootstrap/）似乎都通过转发器动态生成选项卡，这在我的场景中增加了很多复杂性。

我想知道是否有人能指出我正确的方向？

非常感谢大家。

实际上，'ng-click'和'ng-show'指令确实有效 - 它是一些额外的CSS，它覆盖了显示器并使选项卡选择看起来不起作用。解决方案是将上面的选项卡选择器链接更改为：

<a href="" title="" class="tab active" rel="tab1" ng:click="selected=1">Purchases</a>
<a href="" title="" class="tab" rel="tab2" ng:click="selected=2">Products on sale</a>
<a href="" title="" class="tab" rel="tab3" ng:click="selected=3">Last 30 days sales</a>

标签窗格为：

<div id="tab1" class="tabContent" ng-controller="PurchasesCtrl" ng:show="selected == 1">
    Tab content
</div>
<div id="tab2" class="tabContent" ng-controller="SaleProductsCtrl" ng:show="selected == 2">
    Tab content
</div>
<div id="tab3" class="tabContent" ng-controller="Sale30DaysCtrl" ng:show="selected == 3">
    Tab content
</div>
