指导需要在超时的情况下掉落地图引脚

尝试在超时的情况下执行多个引脚，这样看起来更酷，但不起作用

我认为故障可能是在将地图指定为主页时，或者是一个简单的var定义问题。你能看到的任何问题都告诉我。我认为动画应该很酷，按钮方法应该确保你看到它，而不是在你向下滚动足够远之前就已经掉下来了

您的代码中有拼写错误（缺少逗号，google.maps.LatLng需要两个参数）：

var neighborhoods = [
new google.maps.LatLng(46.448114-96.736079),
new google.maps.LatLng(45.46104-98.488264),
new google.maps.LatLng(45.460888-98.498119),
new google.maps.LatLng(44.363302-97.134493),
new google.maps.LatLng(43.760871-96.778317),
new google.maps.LatLng(46.888705-103.194951),
new google.maps.LatLng(44.670711-103.850721),
new google.maps.LatLng(43.839003-101.283079),
new google.maps.LatLng(46.832538-100.76937),
new google.maps.LatLng(46.836574-100.781966),
new google.maps.LatLng(30.325508-96.157669),
new google.maps.LatLng(39.094627-94.437796),
new google.maps.LatLng(31.0451-97.165565)];

应为：

var neighborhoods = [
new google.maps.LatLng(46.448114,-96.736079),
new google.maps.LatLng(45.46104,-98.488264),
new google.maps.LatLng(45.460888, -98.498119),
new google.maps.LatLng(44.363302, -97.134493),
new google.maps.LatLng(43.760871, -96.778317),
new google.maps.LatLng(46.888705, -103.194951),
new google.maps.LatLng(44.670711, -103.850721),
new google.maps.LatLng(43.839003, -101.283079),
new google.maps.LatLng(46.832538, -100.76937),
new google.maps.LatLng(46.836574, -100.781966),
new google.maps.LatLng(30.325508, -96.157669),
