Info

■ If expression is a movie clip or an object, the return value is true. NOTE Unlike the Boolean class constructor, the Boolean() function does not use the keyword new . Moreover, the Boolean class constructor initializes a Boolean object to false if no parameter is specified, while the Boolean() function returns undefined if no parameter is specified. Parameters expression:Object - An expression to convert to a Boolean value. Returns Boolean - A Boolean value. Example trace(Boolean(-1)); // output: true trace(Boolean(0)); // output: false trace(Boolean(1)); // output: true trace(Boolean(true)); // output: true trace(Boolean(false)); // output: false trace(Boolean("true")); // output: true trace(Boolean("false")); // output: true trace(Boolean("Craiggers")); // output: true trace(Boolean("")); // output: false If files are published for Flash Player 6 and earlier, the results differ for three of the preceding examples: trace(Boolean("true")); // output: false trace(Boolean("false")); // output: false trace(Boolean("Craiggers")); // output: false This example shows a significant difference between use of the Boolean() function and the Boolean class. The Boolean() function creates a Boolean value, and the Boolean class creates a Boolean object. Boolean values are compared by value, and Boolean objects are compared by reference. // Variables representing Boolean values are compared by value var a:Boolean = Boolean("a"); // a is true var b:Boolean = Boolean(1); // b is true trace(a==b); // true // Variables representing Boolean objects are compared by reference var a:Boolean = new Boolean("a"); // a is true 38 ActionScript language elements
var b:Boolean = new Boolean(1); // b is true trace(a == b); // false See also Boolean call function call(frame) Deprecated since Flash Player 5. This action was deprecated in favor of the function statement. Executes the script in the called frame without moving the playhead to that frame. Local variables do not exist after the script executes. ■ If variables are not declared inside a block ({}) but the action list was executed with a call() action, the variables are local and expire at the end of the current list. ■ If variables are not declared inside a block and the current action list was not executed with the call() action, the variables are interpreted as Timeline variables. Parameters frame:Object - The label or number of a frame in the Timeline. See also Array function, call (Function.call method) chr function chr(number) : String Deprecated since Flash Player 5. This function was deprecated in favor of String.fromCharCode(). Converts ASCII code numbers to characters. Parameters number:Number - An ASCII code number. Returns String - The character value of the specified ASCII code. Global Functions 39
