百度地图引用时 报出A Parser-blocking, cross site (i.e. different eTLD+1) script

页面引入百度地图api时

chrome控制台报出警示问题 A Parser-blocking, cross site (i.e. different eTLD+1) script, http://api.map.baidu.com/getscript?v=2.0&ak=Kpjp7jddqVUhWK5VkrfNt3YNezY88NtR&services=&t=20170517145936, is invoked via document.write. The network request for this script MAY be blocked by the browser in this or a future page load due to poor network connectivity. If blocked in this page load, it will be confirmed in a subsequent console message.See https://www.chromestatus.com/feature/5718547946799104 for more details. (anonymous) @ api:1

查了一些资料，大概意思是说 ：页面渲染完成后使用了document.write()
这是不被允许的，
根据上面的提示，把api引用url里面的 api 改为 getscript

<script src="http://api.map.baidu.com/api?v=2.0&ak=你申请的ak"></script>

api 改为 getscript以后

<script src="http://api.map.baidu.com/getscript?v=2.0&ak=你申请的ak"></script>
