Info

Returns Number - A number. Example The following code illustrates using the division assignment (/=) operator with variables and numbers: var x:Number = 10; var y:Number = 2; x /= y; trace(x); // output: 5 See also / division operator . dot operator object.property_or_method instancename.variable instancename.childinstance instancename.childinstance.variable Used to navigate movie clip hierarchies to access nested (child) movie clips, variables, or properties. The dot operator is also used to test or set the properties of an object or top-level class, execute a method of an object or top-level class, or create a data structure. Operands object : Object - An instance of a class. The object can be an instance of any of the builtin ActionScript classes or a custom class. This parameter is always to the left of the dot (.) operator. property_or_method - The name of a property or method associated with an object. All the valid methods and properties for the built-in classes are listed in the method and property summary tables for that class. This parameter is always to the right of the dot (.) operator. instancename : MovieClip - The instance name of a movie clip.variable — The instance name to the left of the dot (.) operator can also represent a variable on the Timeline of the movie clip. childinstance : MovieClip - A movie clip instance that is a child of, or nested in, another movie clip. Returns Object - The method, property or movie clip named on the right side of the dot. 134 ActionScript language elements
Example The following example identifies the current value of the variable hairColor in the movie clip person_mc: person_mc.hairColor The Flash 4 authoring environment did not support dot syntax, but Flash MX 2004 files published for Flash Player 4 can use the dot operator. The preceding example is equivalent to the following (deprecated) Flash 4 syntax: /person_mc:hairColor The following example creates a new movie clip within the _root scope. Then a text field is created inside the movie clip called container_mc. The text field's autoSize property is set to true and then populated with the current date. this.createEmptyMovieClip("container_mc", this.getNextHighestDepth()); this.container_mc.createTextField("date_txt", this.getNextHighestDepth(), 0, 0, 100, 22); this.container_mc.date_txt.autoSize = true; this.container_mc.date_txt.text = new Date(); The dot (.) operator is used when targeting instances within the SWF file and when you need to set properties and values for those instances. == equality operator expression1 == expression2 Tests two expressions for equality. The result is true if the expressions are equal. The definition of equal depends on the data type of the parameter: ■ Numbers and Boolean values are compared by value and are considered equal if they have the same value. ■ String expressions are equal if they have the same number of characters and the characters are identical. ■ Variables representing objects, arrays, and functions are compared by reference. Two such variables are equal if they refer to the same object, array, or function. Two separate arrays are never considered equal, even if they have the same number of elements. When comparing by value, if expression1 and expression2 are different data types, ActionScript will attempt to convert the data type of expression2 to match that of expression1. Operators 135
