JavaScript for Sina Weibo mid and address translation

Sina Weibo each Weibo will have a mid, and each Weibo has a separate address, for example: http://www.weibo.com/2722086301/Bw3sxzwzp

Rule: The yellow part of the address is the user ID, the green part is the micro-bo identification string, after analysis should be 62 binary representation. Each tweet has a number called Mid, which is decimal. So the green part of mid and the address can be converted to each other, the JS code of the conversion is as follows:

The code comes from the internet and the copyright belongs to the original author. I just borrowed it.
