大家講道理

string.replace(/<img(.*?)>/g, "[image]")

I just wrote one randomly, I don’t know if it’s right or not

Added a ? to change the regular expression into lazy mode, which will match as little as possible and only match one img at a time.

If ? is not added, it is greedy mode, which will match as many as possible and directly match all img.

給我你的懷抱 
str.replace(/<img[^>]*>/g, "[圖片]");
滿天的星座 
string.replace(/<img.*?>/g,'[圖片]')

Pay attention to two points: (1)*? 為非貪婪模式。（2） g Global matching.
