The great spirit guide, thank you!

See the same problem: https://coding.imooc.com/learn/questiondetail/208.html

For the first time to ask questions, the great god a lot of guidance!

I use the stupid method, strings that will be a problem to the div id=div2:

This piece of string to the base 64 decoding, completely no problem, I don't know where the problem?
