Flash Player 5.

Usage

expression1 != expression2

Parameters

None.

Returns

A Boolean value.

Description

Operator (inequality); tests for the exact opposite of the == operator. If expression1 is equal to expression2, the result is false. As with the == operator, the definition of equal depends on the data types being compared.

Numbers, strings, and Boolean values are compared by value.
Variables, objects, arrays, and functions are compared by reference.

Example

The following example illustrates the result of the != operator:

5 != 8 returns true

5 != 5 returns false

This example illustrates the use of the != operator in an if statement.

a = "David";
b = "Fool" 
if (a != b){
  trace("David is not a fool");
}
