ECMA Section: 12.6.3 The for...in Statement
|
|
Description:
|
|
The production IterationStatement : for ( LeftHandSideExpression in Expression )
|
|
Statement is evaluated as follows:
|
|
|
|
1. Evaluate the Expression.
|
|
2. Call GetValue(Result(1)).
|
|
3. Call ToObject(Result(2)).
|
|
4. Let C be "normal completion".
|
|
5. Get the name of the next property of Result(3) that doesn't have the
|
|
DontEnum attribute. If there is no such property, go to step 14.
|
|
6. Evaluate the LeftHandSideExpression (it may be evaluated repeatedly).
|
|
7. Call PutValue(Result(6), Result(5)). PutValue( V, W ):
|
|
1. If Type(V) is not Reference, generate a runtime error.
|
|
2. Call GetBase(V).
|
|
3. If Result(2) is null, go to step 6.
|
|
4. Call the [[Put]] method of Result(2), passing GetPropertyName(V)
|
|
for the property name and W for the value.
|
|
5. Return.
|
|
6. Call the [[Put]] method for the global object, passing
|
|
GetPropertyName(V) for the property name and W for the value.
|
|
7. Return.
|
|
8. Evaluate Statement.
|
|
9. If Result(8) is a value completion, change C to be "normal completion
|
|
after value V" where V is the value carried by Result(8).
|
|
10. If Result(8) is a break completion, go to step 14.
|
|
11. If Result(8) is a continue completion, go to step 5.
|
|
12. If Result(8) is a return completion, return Result(8).
|
|
13. Go to step 5.
|
|
14. Return C.
