JavaScript .replace不会替换所有出现的事件 [英] JavaScript .replace doesn't replace all occurrences

问题描述

可能重复:
:

要执行全局搜索和替换，请在其中包含g开关正则表达式，或者如果第一个参数是字符串，则包含g在flags参数中.注意:flags参数在v8 Core(Chrome和Node.js)中不起作用，将从Firefox中删除.

应该是:

 "11.111.11" .replace(/\./g，''); 

---

此版本(在编辑时)确实可以在Firefox中使用...

 "11.111.11" .replace('.'，''，'g'); 

...但是，正如在MDN页面上所指出的那样，其支持将很快消失.

How do I replace all occurrences of "/" in a string with "_" in JavaScript?

In JavaScript, "11.111.11".replace(".", "") results in "11111.11". How can that be?

解决方案

Quote from the doc:

To perform a global search and replace, either include the g switch in the regular expression or if the first parameter is a string, include g in the flags parameter. Note: The flags argument does not work in v8 Core (Chrome and Node.js) and will be removed from Firefox.

So it should be:

"11.111.11".replace(/\./g, '');

---

This version (at the moment of edit) does work in Firefox...

"11.111.11".replace('.', '', 'g');

... but, as noted at the very MDN page, its support will be dropped soon.
