我正在尝试结合使用 Angular 的 limitTo 和过滤器，但它似乎无法正常工作。我希望能够在搜索框中输入一个值，然后按搜索。之后，我想通过在过滤器框中输入数字并按应用过滤器来限制显示的结果。但是，当我在那里输入数字时，它不会将结果限制为该数量，而是会清除所有结果。有什么建议么？例如，尝试搜索 simon。然后，在顶部框中输入 2 并单击“应用过滤器”，看看会发生什么。

angular.module('userApp', []).controller('myCtrl', function($scope) {
var vm = this;
$scope.users = [
{'username':'david', 'email':'something@gmail.com', 'name':'Some Name'},

{'username':'ben', 'email':'something@gmail.com', 'name':'Some Name'},

vm.showAll = function() {
$scope.limit = undefined;
};
vm.showMore = function(display) {
$scope.limit = display;
};
vm.search = function(searchBar) {
$scope.searchKeyword = searchBar;
};
});

最佳答案
您应该将它们翻转过来，因为它首先进行限制，然后再进行过滤。因此，将您的 html 更改为:
<tr ng-repeat="person in users | filter: searchKeyword | limitTo: limit">
