对于在想实现地图功能时，百度地图和高德地图都提供了很好的API接口，直接进入官网查找相应的开发文档即可。
我这里使用的是百度地图，首先你得申请一个百度的**，这个很简单，网上很多教程。
货不多说，下面看代码

在layui中需要对其先初始化,对地图一些功能的实现都写在 window.init = function() 里面。
function loadJScript() {
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "//api.map.baidu.com/api?v=2.0&ak=d5Y5C26Xbhr3rBHo3GzzaA7xcXev6NL0&callback=init";
document.body.appendChild(script);
}
window.init = function() {
}
loadScript()
