javascript - 异步函数: TypeError: window.的回调中出现异常scrollTo不是函数(Meteor应用程序)

Question

我正在尝试使用scrollTo(0,0)运行Meteor.js应用程序以使我的每条铁路线都转到页面顶部:

client/lib/router.js:

    Router.route('/services', {
        name: 'services',
        template: 'services',
      onAfterAction: function () {
        scrollTop();
      }  
    });

Router.route('/inquiry', function() {
    this.layout('inquiry');
    onAfterAction: function () {
      scrollTop();
  } 
});

    function scrollTop() {
        window.scrollTo(0, 0);
    }

控制台错误:

meteor.js:880 Exception in callback of async function: TypeError: window.scrollTo is not a function

Answer 1

您的第二条路线不正确，您将函数样式设置与 i-r 的对象样式混合在一起。

Router.route('/inquiry', function() {
    this.layout('inquiry');
    onAfterAction: function () {
      scrollTop();
  } 
});

应该是:

Router.route('/inquiry', {
  template: 'inquiry',
  onAfterAction: function () {
    scrollTop();
  }
});
