You can use limitTo to cap the number of rows -

您可以使用limitTo来限制行数 -

<div ng-repeat="ng-repeat="selectedOwner in selectedOwners | limitTo:3 track by selectedOwner.workerKey"">
    //stuff
</div>

dmoo's solution should be the accepted answer. However, it is also worth mentioning that you can also check the index against a hard-coded value or an angular expression/variable value like so:

dmoo的解决方案应该是公认的答案。但是，还值得一提的是，您还可以根据硬编码值或角度表达式/变量值检查索引，如下所示：

$scope.maxRowLimit = 3;

<div ng-repeat="item in items" ng-if="$index < maxRowLimit">
    //stuff
</div>
