頁面引入百度地圖api時
chrome控制台報出警示問題 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
查了一些資料，大概意思是說 ：頁面渲染完成后使用了document.write()
這是不被允許的，
根據上面的提示，把api引用url里面的 api 改為 getscript
<script src="http://api.map.baidu.com/api?v=2.0&ak=你申請的ak"></script>
api 改為 getscript以后
<script src="http://api.map.baidu.com/getscript?v=2.0&ak=你申請的ak"></script>
