Angular ng-repeat如果內層過濾器沒有值，則隱藏外層過濾器

如果沒有生成的值，我想在特定值的ng-repeat過濾中隱藏外層過濾器div由內部過濾器，這是可能的？Angular ng-repeat如果內層過濾器沒有值，則隱藏外層過濾器

<div class="feedEntry" ng-repeat="entry in entries | orderBy:'-' track by $index" ng-if="entry.userID" ng-if="entry.hasFollowing"> 
    {{entry.hasFollowing}} 
    <span ng-repeat="follow in follows | filter:{following:entry.userID, follower:currentUser.userID}"> 
     <div class="feedUserSubmission" ng-init="entry.hasFollowing = true"> 
      {{entry.name}} 
     </div> 
    </span> 
</div>

嗯，這裏是一個解決辦法，如果我不能找到一個解決方案，我會怎麼做。

您只需執行內部ng-repeat中的$parent.showParent = true，該內部ng-repeat僅在內部ng-repeat的過濾結果影響外部ng-repeat範圍時執行。

然後你會做這樣的事情ng-show="showParent"在外NG重複

<div class="feedEntry" ng-repeat="entry in entries | orderBy:'-' track by $index" ng-show="showParent" ng-if="entry.userID" ng-if="entry.hasFollowing"> 
    {{entry.hasFollowing}} 
    <span ng-repeat="follow in follows | filter:{following:entry.userID, follower:currentUser.userID}" ng-init="$parent.showParent = true"> 

     <div class="feedUserSubmission" ng-init="entry.hasFollowing = true"> 
      {{entry.name}} 
     </div> 
    </span> 
</div>

這並沒有工作，這一切都藏 – Jordash

@Jordash看看這個[小提琴]（http://jsfiddle.net/tbb3os6a/）。我做了同樣的事情，但在ng-repeat中使用ng-init –

這非常棒！ – Jordash

如果你想隱藏的所有內容意父DIV：

<div ng-show="(follows | filter:filterByGroup(entry)).length"> 
    <div class="feedEntry" ng-repeat="entry in entries | orderBy:'-' track by $index" ng-if="entry.userID" ng-if="entry.hasFollowing"> 
     ... 
    </div> 
</div>

你可以利用NG隱藏與內過濾條件

NG隱藏=「（如下| filter：{following：entry.userID，follower：currentUser.userID}）。length == 0「

<div class="feedEntry" ng-repeat="entry in entries | orderBy:'-' track by $index" ng-if="entry.userID" ng-if="entry.hasFollowing" ng-hide="(follows | filter:{following:entry.userID, follower:currentUser.userID}).length == 0"> 
    {{entry.hasFollowing}} 
    <span ng-repeat="follow in follows | filter:{following:entry.userID, follower:currentUser.userID}"> 
     <div class="feedUserSubmission" ng-init="entry.hasFollowing = true"> 
      {{entry.name}} 
     </div> 
    </span> 
</div>
