How to replace all points in a string in JavaScript

I am trying to remove '.'(dot) symbol from my string. and The code that Ive used is

checkedNew = checked.replace('.', "");

Bt when I try to alert the value of checkedNew, for example if the checkedNew has original value U.S. Marshal, the output that I get is US. Marshal, it will not remove the second dot in that string. How do remove all dot symbols?

Split the string on all the .'s and then join it again with empty spaces, like this:

checkedNew = checked.split('.').join("");

Clever, but what it does is not immediately obvious when the maintainer comes along to change it. – Quentin May 14 '12 at 13:41

@Quentin: Neither is your solution if the maintainer isn't overly familiar with Regex. That's what comments are for. :) But I'm biased though, I'm one of those "Regex is evil!" guys. – Elliot Bonneville May 14 '12 at 13:42

I had to also convert the value to a string `checkedNew = checked.toString().split('.').join('');` – Sorin Haidau Jun 22 '14 at 16:03

You need to perform a global replacement as, by default, replace only performs one replacement. In theory you can pass an instruction to be global as the third argument, but that has some compatibility issues. Use a regular expression instead.

checkedNew = checked.replace(/\./g, "");

replace will only replace the first occurance. To get around this, use a regex with the global option turned on:

checked.replace(/\./g, '');
