ECMA Section: 11.2.1 Property Accessors
|
|
Description:
|
|
|
|
Properties are accessed by name, using either the dot notation:
|
|
MemberExpression . Identifier
|
|
CallExpression . Identifier
|
|
|
|
or the bracket notation: MemberExpression [ Expression ]
|
|
CallExpression [ Expression ]
|
|
|
|
The dot notation is explained by the following syntactic conversion:
|
|
MemberExpression . Identifier
|
|
is identical in its behavior to
|
|
MemberExpression [ <identifier-string> ]
|
|
and similarly
|
|
CallExpression . Identifier
|
|
is identical in its behavior to
|
|
CallExpression [ <identifier-string> ]
|
|
where <identifier-string> is a string literal containing the same sequence
|
|
of characters as the Identifier.
|
|
|
|
The production MemberExpression : MemberExpression [ Expression ] is
|
|
evaluated as follows:
|
|
|
|
1. Evaluate MemberExpression.
|
|
2. Call GetValue(Result(1)).
|
|
3. Evaluate Expression.
|
|
4. Call GetValue(Result(3)).
|
|
5. Call ToObject(Result(2)).
|
|
6. Call ToString(Result(4)).
|
|
7. Return a value of type Reference whose base object is Result(5) and
|
|
whose property name is Result(6).
|
|
|
|
The production CallExpression : CallExpression [ Expression ] is evaluated
|
|
in exactly the same manner, except that the contained CallExpression is
|
|
evaluated in step 1.
