Description:
|
|
|
|
MemberExpression:
|
|
PrimaryExpression
|
|
MemberExpression[Expression]
|
|
MemberExpression.Identifier
|
|
new MemberExpression Arguments
|
|
|
|
new NewExpression
|
|
|
|
The production NewExpression : new NewExpression is evaluated as follows:
|
|
|
|
1. Evaluate NewExpression.
|
|
2. Call GetValue(Result(1)).
|
|
3. If Type(Result(2)) is not Object, generate a runtime error.
|
|
4. If Result(2) does not implement the internal [[Construct]] method,
|
|
generate a runtime error.
|
|
5. Call the [[Construct]] method on Result(2), providing no arguments
|
|
(that is, an empty list of arguments).
|
|
6. If Type(Result(5)) is not Object, generate a runtime error.
|
|
7. Return Result(5).
|
|
|
|
The production MemberExpression : new MemberExpression Arguments is evaluated as follows:
|
|
|
|
1. Evaluate MemberExpression.
|
|
2. Call GetValue(Result(1)).
|
|
3. Evaluate Arguments, producing an internal list of argument values
|
|
(section 0).
|
|
4. If Type(Result(2)) is not Object, generate a runtime error.
|
|
5. If Result(2) does not implement the internal [[Construct]] method,
|
|
generate a runtime error.
|
|
6. Call the [[Construct]] method on Result(2), providing the list
|
|
Result(3) as the argument values.
|
|
7. If Type(Result(6)) is not Object, generate a runtime error.
|
|
8 .Return Result(6).
