JavaScript .replace doesn't replace all occurrences

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.

With a regular expression and flag g you got the expected result

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

it's IMPORTANT to use a regular expression because this:

"11.111.11".replace('.', '', 'g'); // dont' use it!!

is not standard

First of all, replace() is a javascript function, and not a jquery function.

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:

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