在index.html上的js导入时定义变量

Question

I have a JavaScript script which a user can import on his website. This script will basicly create an socket connection which transfers small messages which the script will display on the client side.

I will have more than one user on more than one website. So I need an identifier to handle the identification of the website.

I plan to use something like a CDN to host this script, so the user can just import it within his index.html . The script does always the same logic but with different Connection Values. Im pretty sure I dont have to create the same files, with different identifier values, for every websites which will use my script, but so far i have no idea how to tell the script which identifier value it should use.

Is there a good way to handle such problems?

将连接ID​​存储在加载脚本的HTML文档中（例如<script src="http://cdn.example.com/your.js" data-connection-id="74893872"></script> ），拉使用您的JS从DOM中获取。
