javascript - 嵌套 ngRepeat limitTo 不起作用

Question

我目前遇到 ng-repeat 问题，并限制了 View 中显示的元素数量。我想知道这是否与嵌套循环有关。这是代码:

<li style="cursor:pointer; margin:8px;" class="span3" ng-repeat="psp in preSplitPrompts" ng-click="selectRelatedSplitPanels($index)">

    <div ng-class="$first ? 'panelBackground' : 'altPanelBackground'" class="thumbnail splitPanel">
        <h3>{{ (psp.promptname) ? psp.promptname : "No Name From API" }}</h3>
        <hr>
        <h2 ng-repeat="postsplit in psp.postSplit | limitTo: 1">{{ postsplit.metrics.preSplitTotalCount ? postsplit.metrics.preSplitTotalCount : 0 }}</h2>
        <p>Visits</p>
    </div>

</li>

我尝试通过执行 limitTo:1 来限制列表项，效果很好。仅当试图限制后分割时。感谢您的帮助。

编辑:

此代码有效:

<li style="cursor:pointer; margin:8px;" class="span3" ng-repeat="psp in preSplitPrompts | limitTo: 1" ng-click="selectRelatedSplitPanels($index)">

    <div ng-class="$first ? 'panelBackground' : 'altPanelBackground'" class="thumbnail splitPanel">
        <h3>{{ (psp.promptname) ? psp.promptname : "No Name From API" }}</h3>
        <hr>
        <h2 ng-repeat="postsplit in psp.postSplit">{{ postsplit.metrics.preSplitTotalCount ? postsplit.metrics.preSplitTotalCount : 0 }}</h2>
        <p>Visits</p>
    </div>

</li>

这是数据对象:

试试这个:

ng-class="{$first ? 'panelBackground' : 'altPanelBackground'}"
