带标记表达式的Javascript RegExp

Question

I would like to know if there is a way to perform replacement with regular expressions in JS using tagged expressions, like scintilla engine does (used in Notepad++, for example). For instance, to replace numbers with a colon as decimal separator by a dot, you may use the following expressions in Notepad++:

regexp: /([0-9]+),([0-9]{2})/ replace: \\1.\\2

Could I do something like this in JS?

Regards José

Answer 1

是。

str = str.replace(/([0-9]+),([0-9]{2})/, '$1.$2');

Answer 2

你当然可以！

"My test string with a 56,35% chance of success".replace(/([0-9]+),([0-9]{2})/gi, "$1.$2");

Answer 3

Use replace . Good documentation here:
