I would like to have the result :
28,12,2016
From this string "28/12/2016"
I tried :
("28/12/2016").replace('/',',');
==>"28,12/2016"
I don't know how to delete the second /and the " "

use split and join method
var a="28/12/2016";
var ans=a.split("/").join(",");
console.log(ans);

with the following code can get the 1 in the string.
var match = /[0-9]+/.exec('[1][2]');
console.log(match);
How do i get the 2 and not the 1 ?
Try with this regex
console.log(/(\[[0-9]\])+/.exec('[1][2]'));
I think it's only a matter of escaping the square brackets

I have a string I am trying to get the last character with jquery. How would I do that?

or

Use .split():
stringTemp.split('_')[1]

I want to split string
"abcdefgh"
to
"ab","cd","ef","gh"
using javascript split()
"abcdefgh".split(???)
Can you please help ?
Instead of split, try match:
var text = "abcdefgh";
print(text.match(/../g));
prints:
ab,cd,ef,gh
as you can see on Ideone.
