用angular中的ng-repeat和ng-show来实现tab选项卡

<!--设置nav导航栏-->
    <ul>
        <!--nav中的导航栏内容，并给每个li设置点击事件，设置是否显示class样式-->
        <li ng-repeat="v in wd" ng-click="wD($index)" class="{{wD1($index)?‘wd‘:‘‘}}">
            {{v.font}}
        </li>
    </ul>
    <!--设置tab选项卡的内容，并用ng-show来判断哪个tab内容显示-->
    <ul ng-repeat="v in wd1" ng-show="wDBottom($index)">
        <!--tab选项卡里的内容-->
        <li ng-repeat="vv in v.Font">
            {{vv.font}}
        </li>
    </ul>
