The split() method is used to split a string into an array of strings.

Example 1

In this example, we will split the string in different ways: 

var str="How are you doing today?"
document.write(str.split(" ") + "
")
document.write(str.split("") + "
")
document.write(str.split(" ",3))
//输出：
//How,are,you,doing,today?
//H,o,w, ,a,r,e, ,y,o,u, ,d,o,i,n,g, ,t,o,d,a,y,?
//How,are,you

Example 2

In this example, we will split a string with a more complex structure: 

"2:3:4:5".split(":") //将返回["2", "3", "4", "5"]
"|a|b|c".split("|") //将返回["", "a", "b", "c"]

Example 3

Use the following code to split sentences into words: 

var words = sentence.split(' ')
//或者使用正则表达式作为 separator：
var words = sentence.split(/\s+/)

Example 4

If you want to split a word into letters, or a string into characters, use the following code: 

"hello".split("") //可返回 ["h", "e", "l", "l", "o"]
//若只需要返回一部分字符，请使用 howmany 参数：
"hello".split("", 3) //可返回 ["h", "e", "l"]

Example: 

<html>
<body>
<script type="text/javascript">
var str="How are you doing today&#63;"
document.write(str.split(" ") + "<br />")
document.write(str.split("") + "<br />")
document.write(str.split(" ",3))
</script>
</body>
</html>
