JavaScript ignoreCase Property : RegExp Object

Secondary Nav


The ignoreCase property of the RegExp object is a flag which indicates whether the case is to be ignored during pattern matching in a string. The value of ignoreCase is true if the 'i' flag was used; otherwise, false.


Implemented in JavaScript 1.2



Example :

The following web document demonstrates how the ignoreCase property can be used.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />
<title>JavaScript Regexp ignoreCase Property : Example-1</title>
<h1 style="color: red">JavaScript Regexp ignoreCase Property</h1>
<hr />
<script type="text/javascript">
//This is done to make the following JavaScript code compatible to XHTML. <![CDATA[
// A regular expression on the pattern “The”
strpat1 = new RegExp("the","i");
// Declare a string.
str1 = "The Quick Brown Fox Jumps Over The Lazy Dog";
// Executes search for pattern match with exec() and store result in an array array1,array2.
array1 = strpat1.exec(str1);
document.write("The value of RegExp.ignoreCase (for 'the' pattern) is: " + strpat1.ignoreCase);
