JScript Split Method 1

[captedgar]

Hi there

I'm trying to figure out what the following syntax for split means in the following line of the code

arrTest[0].split('/')[0]

what does ('/')[0] means in split('/')[0]?

please can anyone explain

Hi

what does ('/')[0] means in split('/')[0]?

[tt]split('/')[/tt] - the [tt]split()[/tt] method splits the string in pieces separated by the given string or regular expression and returns the result as an array.
[tt][0][/tt] - refers to the element of the array at the position given by the index.

Give it a try in the FireBug Console :

[blue]>>> arrTest=['foo/bar/baz','something/else','some/more'][/blue]
[b][[/b] [red]"foo/bar/baz"[/red], [red]"something/else"[/red], [red]"some/more"[/red] [b]][/b]
[blue]>>> arrTest[0][/blue]
[red]"foo/bar/baz"[/red]
[blue]>>> arrTest[0].split('/')[/blue]
[b][[/b] [red]"foo"[/red], [red]"bar"[/red], [red]"baz"[/red] [b]][/b]
[blue]>>> arrTest[0].split('/')[0][/blue]
[red]"foo"[/red]

Its spliting the string at the slash character and returning the value of the first section that was split off.

In other words, for a string like: "This/is/a/string" it would put the word "This" in the array.
