问题描述

如何在向下滚动页面时实现内容的渐进式加载?否则会同时加载 1000 张图片.

解决方案

我不想使用 ngInfiniteScroll 另一个人发布的因为我的移动应用程序不使用 jQuery 所以没有意义加载它只是为了这个.

无论如何,我找到了一个 jsfiddle 用纯 Javascript 解决了这个问题.

HTML

<ul><li ng-repeat="i in items"></li>

JavaScript

function Main($scope) {$scope.items = [];无功计数器 = 0;$scope.loadMore = function() {for (var i = 0; i <5; i++) {$scope.items.push({编号:计数器});计数器 += 10;}};$scope.loadMore();}angular.module('scroll', []).directive('whenScrolled', function() {返回函数(范围,榆树,属性){var raw = elm[0];elm.bind('scroll', function() {if (raw.scrollTop + raw.offsetHeight >= raw.scrollHeight) {scope.$apply(attr.whenScrolled);}});};});

How do I implement progressive loading of content as you scroll down the page? Otherwise 1000 images would load at the same time.

解决方案

I didn't want to use ngInfiniteScroll the other guy posted as my mobile app does not use jQuery so there is no point in loading it just for this.

Anyhow, I found a jsfiddle with pure Javascript that solves this problem.

HTML

<div id="fixed" when-scrolled="loadMore()">
    <ul>
        <li ng-repeat="i in items"></li>
    </ul>
</div>

JavaScript

function Main($scope) {
    $scope.items = [];
    var counter = 0;
    $scope.loadMore = function() {
        for (var i = 0; i < 5; i++) {
            $scope.items.push({
                id: counter
            });
            counter += 10;
        }
    };
    $scope.loadMore();
}

angular.module('scroll', []).directive('whenScrolled', function() {
    return function(scope, elm, attr) {
        var raw = elm[0];
        elm.bind('scroll', function() {
            if (raw.scrollTop + raw.offsetHeight >= raw.scrollHeight) {
                scope.$apply(attr.whenScrolled);
            }
        });
    };
});
