How do I replace all string values in this JavaScript statement?

Question

replace all occurrences in a string

I have this string:

"12-3-02"

And I would like to convert it to :

"12/3/02"

How would I do this? I 've tried :

.replace(/-/,"/")

But this only replaces the first one it finds. How do I replace all instances?

That's nothing jQuery related, `.replace()` is a method of strings. — Felix Kling, Mar 02 '12 at 16:17
@Nicocube: `g` stands for "global" replacement, not "general". — gen_Eric, Mar 02 '12 at 16:19

One of these (using split, or a global RegEx flag):

str = str.split('-').join('/'); // No RegExp needed

str = str.replace(/-/g, '/');   // `g` (global) has to be added.

I can't test this at the moment, but do you need the `replace ()` as well as the `split ()`? – David Thomas Mar 02 '12 at 16:19

@David: Nope, that's why Rob says *"**One** of these:"* – Felix Kling Mar 02 '12 at 16:21
The answer was perhaps edited to make that more explicit, either while I asked, or afterwards. ...that or I didn't read closely enough. =/ – David Thomas Mar 02 '12 at 16:31

Add the g (global) modifier to the regex, to match all -s.

.replace(/-/g,"/")

If you want to replace all the occurences of - by / then use this where g specifies the global modifier.

"12-3-02".replace(/-/g,"/");

Try with:

"12-3-02".replace(/-/g, '/');

This question has been posed about a thousand times, but no one has ever considered the possibility that, in the real world, characters can occur in places where you might not expect.(Typo's in input or replacing parts of words when you only wanted to replace a single word...

var reformat = '01-11-2012'.replace(/(([0-9]+)(?=\-))\-(?=[0-9])/g,'$1/');

This will only replace '-' characters that are preceded and followed by a number.
