Question

我试图使用流星开发者组的包来使用jquery航点。我只是尝试从入门文档中做最简单的航点。

var waypoint = new Waypoint({
    element: document.getElementById('tester'),
    handler: function(direction) {
        alert('direction: ' + direction);
    }
});

当我去localhost时，它说“未被引用的引用;没有定义Waypoint”但是当我查看header标签时，包含了waypoints并且它包含在jquery之后？

Answer 1

收到相同的错误消息后，在尝试下面的两个包之后：

meteor添加jquery-waypoints ..和 meteor add mrt：jquery-waypoints2

既没有奏效，也收到了同样的消息。但是，我安装了下面的软件包，功能也很好。

        return numberToText + " ";
    }

}

以下代码适用于已安装的软件包。

meteor add bigu:waypoints

仍然无法弄清楚对方官员的错误是什么？＆＃39;包，但我希望这会有所帮助。

Answer 2

看起来好像没有安装航点。如果你正在使用流星，那么你可能已经有了npm：

转到终端并键入

npm install waypoints

或者如果你有凉亭

bower install waypoints

只是为了确保你已经安装了它，运行：

npm list

你应该在那里看到它

在Meteor中使用Jquery-waypoints
