Example of how to use the string split function in JavaScript

Let's take a look at the following code:

1 2 3 4 5 6

<Script type = "text/javascript"> Var str = "How are you doing today? " Document. write (str. split ("") + "<br/> ") Document. write (str. split ("") + "<br/> ") Document. write (str. split ("", 3 )) </Script>

The output result is as follows:

1 2 3

How, are, you, doing, today? H, o, w, a, r, e, y, o, u, d, o, I, n, g, t, o, d,, y ,? How, are, you

Example:

1 2	"2: 3: 4: 5". split (":") // Returns ["2", "3", "4", "5"] "| A | B | c". split ("|") // ["", "a", "B", "c"]

Use the following code to split sentences into words:

1	Var words = sentence. split ('')

If you want to split words into letters or strings into characters, use the following code:

1	"Hello". split ("") // you can return ["h", "e", "l", "l", "o"]

If you only need to return a part of the characters, use the howmany parameter:

1	"Hello". split ("", 3) // you can return ["h", "e", "l"]

Or use the regular expression as the separator:

1	Var words = sentence. split (/\ s + /)
