JavaScript and XPages reference
This reference describes the JavaScript™ language elements, Application Programming Interfaces (APIs), and other artifacts that you need to create scripts, plus the XPages simple actions.
- JavaScript™ language elements (JavaScript)
  The JavaScript™ language elements are based on the ECMAScript Language Specification Standard ECMA-262 (see http://www.ecma-international.org/publications/standards/Ecma-262.htm). The JavaScript described here applies to the server-side interpreter. Client-side scripts are interpreted by the browser.
- Simple actions (JavaScript)
  A simple action performs a pre-programmed activity that can be modified by arguments.

compareToIgnoreCase (JavaScript)

Compares two strings ignoring case.

Defined in

Syntax

compareToIgnoreCase(str:string) : int


Parameters	Description
`str`	The comparison string.


Returns	Description
`int`	0 if the two strings are equal ignoring case.

Usage

String 1 is this object. String 2 is the parameter. If the two strings are equal ignoring case, the return value is 0. If the strings are not equal, the return value is string 1 minus string 2 for the first character that differs (using the Unicode values of the string).

Examples

This example makes an equal comparison.

var cities = new String("Paris   Moscow   Tokyo");
var string2 = "PARIS   MOSCOW   TOKYO";
if (cities.compareToIgnoreCase(string2) == 0)
	return cities + " == " + string2;
else
	return cities + "!= " + string2;
