尝试使用超时执行多个引脚，使其看起来更酷但不起作用

我认为故障可能在于将地图指定为主页或简单的var定义问题任何你能看到的东西让我知道。我认为动画应该非常酷，按钮方法应该确保你看到它而不是在你向下滚动到足够远看之前它已经丢失。某些事情已被打破

您的代码中存在拼写错误（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)];

应该是：

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)];
