Quote from the doc:
来自文档的引用：
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.
要执行全局搜索和替换，请在正则表达式中包含 g 开关，或者如果第一个参数是字符串，则在 flags 参数中包含 g。注意：flags 参数在 v8 Core（Chrome 和 Node.js）中不起作用，将从 Firefox 中删除。
So it should be:
所以应该是：
"11.111.11".replace(/\./g, '');
This version (at the moment of edit) does work in Firefox...
此版本（在编辑时）在 Firefox 中确实有效...
"11.111.11".replace('.', '', 'g');
... but, as noted at the very MDN page, its support will be dropped soon.
...但是，正如 MDN 页面所指出的，它的支持很快就会被取消。

使用正则表达式和标志，g您得到了预期的结果

使用正则表达式很重要，因为：
"11.111.11".replace('.', '', 'g'); // dont' use it!!

First of all, replace() is a javascript function, and not a jquery function.
首先，replace() 是一个 javascript 函数，而不是一个 jquery 函数。
The above code replaces only the first occurrence of "." (not every occurrence). To replace every occurrence of a string in JavaScript, you must provide the replace() method a regular expression with a global modifier as the first parameter, like this:
上面的代码只替换了第一次出现的“.”。（并非每次都发生）。要替换 JavaScript 中出现的每个字符串，您必须为 replace() 方法提供一个正则表达式，并以全局修饰符作为第一个参数，如下所示：
"11.111.11".replace(/\./g,'')
