Example of the string splitting function split in JavaScript

This article illustrates the use of the string splitting function split in JavaScript as an example. Share with you for your reference. The details are as follows:

Let's look at this code first:

<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 results are as follows:

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:

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

You can split a sentence into words using the following code:

var words = sentence.split(' ')

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

"hello".split("") // Can be returned  ["h", "e", "l", "l", "o"]

If you only need to return 1 part of the characters, please use the howmany parameter:

"hello".split("", 3)  // Can be returned  ["h", "e", "l"]

Or use regular expressions as separator:

var words = sentence.split(/\s+/)
