我写了一个包含块列表的应用程序.
每个块包含指向其他块的链接.
当点击一个块的链接,例如#/ home / page-19时,该页面根据当前位置向下/向上设置动画.
这一切目前都有效但是当点击锚点并且路线更新时,浏览器跳到顶部然后动画下来,我需要它从当前位置动画.
我写了一个指令,将preventDefault添加到所有锚点.
请参阅下面的JS小提琴.

JavaScript的：
var app = angular.module('app',[]);
/*

*/
app.controller( 'appController',function( $scope ) {
});
app.controller( 'routeController',function( $scope,$routeParams ) {
//When route change,check if page has been updated and run animateScroll directive

$scope.animateScroll($routeParams.page);

});
/*

*/
app.config(['$routeProvider',function($routeProvider) {
$routeProvider.
