Question

例如我有这个重复列表：

$.getJSON("/svrBooking/json/getEmployeesByManager",{
            "manager": "Paul Walker",
            "endDate": endDate,
            "startDate": startDate,
            "ajax": 'true'
            }, function (result) {...});

我可以以某种方式（如果没有更改控制器会更好，因为它是一个指令）检查：如果过滤结果不为空 - 然后显示整个<ul> <li class="suggestion-item" ng-repeat="item in suggestionList.items | filter: {id: 2} track by track(item)">{{item.text}}</li> <ul>，如果没有，则隐藏ul。我的意思是：

ul

Answer 1

您可以将过滤结果分配给变量

<ul ng-show="filterResult && filterResult.length">
    <li class="suggestion-item" ng-repeat="item in filterResult = (suggestionList.items | filter: {id: 2}) track by track(item)">{{item.text}}</li>
<ul>

Answer 2

使用 $ parent 即可实现

<ul ng-show="suggestionListItem.length" >
 <li class="suggestion-item" ng-repeat="item in ($parent.suggestionListItem = (suggestionList.items | filter: {id: 2} track by track(item)))">{{item.text}}</li>
<ul>

angularjs：检查ng-repeat中过滤器的长度
