javascript - 在javascript中获取ng-reapeat的$index(代码隐藏)

Question

如何从代码隐藏中获取$index的实际值？

我的html是:

<div class="list-group nav nav-stacked">
    <a 
        ng-repeat="data in dbdata | orderBy:'heading' | filter:tocsearch"
        ng-click="jumpToManual(data.user_manual_id)"
        class="list-group-item"
        ng-class="{'active':data.user_manual_id===manualdata.page_id, 'selected': selectedIndex}">
        {{data.heading}}
    </a>
</div>
<button class="btn btn-default pull-right" ng-click="nextManual(data.$index)" type="button">Next &rarr;</button>

目标是通过nextManual函数实现ng-repeat之外的按钮，其中传递ng-repeat的$index。

您可以将 $parent.$index 作为参数传递给 ngClick 函数:

<div class="list-group nav nav-stacked">
    <a ng-repeat="data in dbdata | orderBy:'heading' | filter:tocsearch" 
       ng-click="jumpToManual(data.user_manual_id, $parent.$index)" 
       class="list-group-item" 
       ng-class="{'active':data.user_manual_id===manualdata.page_id, 'selected': selectedIndex}">
       {{data.heading}}
    </a>
</div>
