如何使用AngularJS加载更多元素? [英] How to load more elements with AngularJS?

问题描述

有一阵子，我试图找到如何使用Angular来增加负载(来自数组元素)的按钮.

for a while I am trying to find how to make a load more(elements from an array) button,using Angular.

我在数组中有9个元素，我使用ng-repeat对其进行循环，并使用limitTo:3首先输出3.

I have 9 elements in array, I use ng-repeat to loop them, and limitTo:3 to output first 3.

问题:

1:是否可以仅使用角度按钮来制作更多的负荷按钮?(例如，更多负荷的按钮位于底部)

1: is possible to make a load more button using only angular?(load more button is at bottom in example)

2:如果没有，如何使用jQuery进行这项工作?

2: if not, how to make this work using jQuery?

推荐答案

您无需考虑jQuery，因为您可以使用AngularJS本身轻松解决此问题.

You don't need to think of jQuery, as you could solve this problem easily by using AngularJS itself.

您可以在控制器内维护一个变量，将其命名为limit，然后在loadMore()函数内递增limit变量.

You could maintain a variable inside your controller, name it as limit, then increment the limit variable inside loadMore() function.

标记

<div ng-repeat="elem in travel.cruise | limitTo:travel.limit" class="cruises">

  ....COntent here...

</div>

控制器

app.controller('TravelController', function($scope) {
    var vm = this;
    vm.cruise = cruises;
    vm.limit = 3;

    $scope.loadMore = function() {
      var increamented = vm.limit + 3;
      vm.limit = incremented > vm.cruise.length ? vm.cruise.length : increamented;
    };
});
