Examples of split usages of string partitioning functions in JavaScript

Source: Internet
Author: User

Let's look at the following code:

1 2 3 4 5 6 <script type= "Text/javascript" > var str= "How are to doing today?" document.write (Str.split ("") + "<br/>") d Ocument.write (Str.split ("") + "<br/>") document.write (Str.split ("", 3)) </script>

The output results are 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,a,y,? How,are,you


1 2 "2:3:4:5". Split (":")//will return ["2", "3", "4", "5"] "|a|b|c". Split ("|") will return ["", "a", "B", "C"]

Using the following code, you can split a sentence into words:

1 var words = Sentence.split (')

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

1 "Hello". Split ("")//May return ["H", "E", "L", "L", "O"]

To return only a subset of the characters, use the Howmany parameter:

1 "Hello". Split ("", 3)//May return ["H", "E", "L"]

or use regular expressions as separator:

1 var words = Sentence.split (/s+/)
