Usage examples of string splitting function split in JavaScript_javascript skills

The example in this article describes the usage of the string splitting function split in JavaScript. Share it with everyone for your reference. The details are as follows:

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

Use the following code to split sentences into words:

var words = sentence.split(' ')

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"]

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

"hello".split("", 3)  //可返回 ["h", "e", "l"]

Or use regular expression as separator:

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

I hope this article will be helpful to everyone’s JavaScript programming design.
