JavaScript split() Method

String Object Reference Complete String Object Reference

Definition and Usage

The split() method is used to split a string into an array of strings.

Syntax

stringObject.split(separator, howmany)

Parameter Description
separator Required. Specifies the character, regular expression, or substring that is used to determine where to split the string
howmany Optional. Specify how many times split should occur. Must be a numeric value

Tips and Notes

Note: If an empty string ("") is used as the separator, the string is split between each character.

Example

In this example we will split up a string in different ways:

<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 of the code above will be:

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

Web Load and Performance Testing   

WAPT is a load, stress and performance testing tool for websites and web-based applications. In contrast to "800-pound gorilla" load testing tools, it is designed to minimize the learning curve and give you an ability to create a heavy load from a regular workstation. WAPT is able to generate up to 3000 simultaneously acting virtual users using standard hardware configuration. Virtual users in each profile are fully customizable. Basic and NTLM authentication methods are supported. Graphs and reports are shown in real-time at different levels of detail, thus helping to manage the testing process.
