JavaScript不会替换字符串的最后一个符号

Question

I have try to replace a symbol in JavaScript, but somehow this is always only replace the 1st symbol of the string instead of replaced all the symbol.

JavaScript :

var note = "test'test'test'";
note = note .replace("'", "'");

Output :

test'test'test'

Does anyone know how can I can replace all ' symbols with ' ??

Answer 1

Use regex substitution and add a g flag to make it global:

> "test'test'test'".replace(/'/g, ''');
"test'test'test'"

Answer 2

Use g suffix for the Global substituation.

This is the right way:

note = "test'test'test'";
note.replace(/\'/g,"'")

Answer 3

试试这个笔记.replace（/ \\'/ g，'''）;
