Regular Expression

String pattern

Writing a simple string pattern

Now let write a simple string pattern to split the following string object to an array--starr:

var st="JavaScript is powerful web scripting language";

This string can be split by the space character. Therefore, string pattern should be:

var stpat=/ /;

Then by supplying this string pattern as an argument of the split() method you will get an array of strings.

var starr=st.split(stpat);

Now you see the complete example code as shown below:

<html>
<head>
<title>Regular Expression-a simple string pattern</title>

<script language="JavaScript" type="text/javascript">

var st="JavaScript is powerful web scripting language";
var stpat=/ /;
var starr=st.split(stpat);
var i;
for(i=0;i<starr.length;i++)
document.write(starr[i]+"<br>");

</script>

</head>
<body>
</body>
</html>
