Example of how to use the string split function in JavaScript: javascriptsplit

This document describes the use of the string splitting function in JavaScript. Share it with you for your reference. The details are as follows:

Let's take a look at the following code:

<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:

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


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

Use the following code to split sentences into words:

var words = sentence.split(' ')

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

"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:

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

Or use the regular expression as the separator:

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

I hope this article will help you design javascript programs.
