推荐答案

Inna建议的代码曾经有效，但从iOS10.3起停止工作.我进行了一些研究，发现我们需要对其稍作更改，只需将"%%"更改为单个％"即可.

The codes suggested by Inna used to work but stopped working from iOS10.3. I did some research and found that we need to make a slight change to it, just changing "%%" to a single "%".

因此JS代码应为:

let js = "document.getElementsByTagName('body')[0].style.webkitTextSizeAdjust='\(fontSize)%'"
