这里我正在做Google map waypoint API，它工作正常。点击提交按钮然后地图将在此地图中显示waypoint1＆amp; waypoint 2提交静态instedd这个我想显示empName（它是JSON响应）。我试过像我删除了航点静态值而不是我给定的值。因为这不能正常显示姓氏，怎么能这样做。

您可以在下面的行中使用res.data[(i - 1)].empName。
waypts[i].marker = createMarker(legs[i].start_location, res.data[(i - 1)].empName, legs[i].start_address, "yellow", String.fromCharCode("A".charCodeAt(0) + i));
