Evaluate the Expression. 30 2. Call GetValue(Result(1)). 31 3. Call ToObject(Result(2)). 32 4. Let C be "normal completion". 33 5. Get the name of the next property of Result(3) that doesn't have the 34 DontEnum attribute. If there is no such property, go to step 14. 35 6. Evaluate the LeftHandSideExpression ( it may be evaluated repeatedly). 36 7. Call PutValue(Result(6), Result(5)). PutValue( V, W ): 37 1. If Type(V) is not Reference, generate a runtime error. 38 2. Call GetBase(V). 39 3. If Result(2) is null, go to step 6. 40 4. Call the [[Put]] method of Result(2), passing GetPropertyName(V) 41 for the property name and W for the value. 42 5. Return. 43 6. Call the [[Put]] method for the global object, passing 44 GetPropertyName(V) for the property name and W for the value. 45 7. Return. 46 8. Evaluate Statement. 47 9. If Result(8) is a value completion, change C to be "normal completion 48 after value V" where V is the value carried by Result(8). 49 10. If Result(8) is a break completion, go to step 14. 50 11. If Result(8) is a continue completion, go to step 5. 51 12. If Result(8) is a return completion, return Result(8). 52 13. Go to step 5. 53 14. Return C. 54 55 Author: christine (at) netscape.com 56 Date: 11 september 1997 57 */ 58 var SECTION = "12.6.3-4"; 59 var VERSION = "ECMA_1"; 60 startTest(); 61 var TITLE = "The for..in statment"; 62 var error = err; 63 64 writeHeaderToLog( SECTION + " "+ TITLE); 65 66 var testcases = new Array(); 67 68 // for ( LeftHandSideExpression in Expression ) 69 // LeftHandSideExpression:NewExpression:MemberExpression 70 71 testcases[testcases.length] = new TestCase( SECTION, 72 "bad left-hand side expression", 73 "error", 74 "" ); 75 76 var o = new MyObject(); 77 var result = 0; 78 79 for ( this in o) { 80 result += this[p]; 81 } 82 83 test(); 84 85 function test() { 86 for ( tc=0; tc < testcases.length; tc++ ) { 87 testcases[tc].passed = writeTestCaseResult( 88 testcases[tc].expect, 89 testcases[tc].actual, 90 testcases[tc].description +" = "+ 91 testcases[tc].actual ); 92 93 testcases[tc].reason += ( testcases[tc].passed ) ?
