{} (object initializer)
Availability
Flash Player 5.
Usage
object = {name1: value1, name2: value2,...nameN: valueN}
{expression1; [...expressionN]}
Parameters
object
The object to create.
name1,2,...N The names of the properties.
value1,2,...N The corresponding values for each name property.
Returns
Usage 1: An Object object.
Usage 2: Nothing, except when a function has an explicit
return statement, in which case the
return type is specified in the function implementation.
Description
Operator; creates a new object and initializes it with the specified name and value property pairs.
Using this operator is the same as using the
new Object syntax and populating the property pairs
using the assignment operator. The prototype of the newly created object is generically named the
Object object.
This operator is also used to mark blocks of contiguous code associated with flow control
statements (
for, while, if, else, switch) and functions.
For more information, see “Operator precedence and associativity” in Using ActionScript in Flash.
Example
The first line of the following code creates an empty object using the object initializer ({})
operator; the second line creates a new object using a constructor function:
var object:Object = {};
var object:Object = new Object();
The following example creates an object account and initializes the properties name, address,
city, state, zip, and balance with accompanying values:
var account:Object = {name:"Macromedia, Inc.",
address:"600 Townsend Street",
city:"San Francisco",
state:"California",
zip:"94103",
balance:"1000"};
for (i in account) {
trace("account."+i+" = "+account[i]);
}
