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