Evaluate the Expression. michael@0: 2. Call GetValue(Result(1)). michael@0: 3. Call ToObject(Result(2)). michael@0: 4. Let C be "normal completion". michael@0: 5. Get the name of the next property of Result(3) that doesn't have the michael@0: DontEnum attribute. If there is no such property, go to step 14. michael@0: 6. Evaluate the LeftHandSideExpression (it may be evaluated repeatedly). michael@0: 7. Call PutValue(Result(6), Result(5)). PutValue( V, W ): michael@0: 1. If Type(V) is not Reference, generate a runtime error. michael@0: 2. Call GetBase(V). michael@0: 3. If Result(2) is null, go to step 6. michael@0: 4. Call the [[Put]] method of Result(2), passing GetPropertyName(V) michael@0: for the property name and W for the value. michael@0: 5. Return. michael@0: 6. Call the [[Put]] method for the global object, passing michael@0: GetPropertyName(V) for the property name and W for the value. michael@0: 7. Return. michael@0: 8. Evaluate Statement. michael@0: 9. If Result(8) is a value completion, change C to be "normal completion michael@0: after value V" where V is the value carried by Result(8). michael@0: 10. If Result(8) is a break completion, go to step 14. michael@0: 11. If Result(8) is a continue completion, go to step 5. michael@0: 12. If Result(8) is a return completion, return Result(8). michael@0: 13. Go to step 5. michael@0: 14. Return C. michael@0: michael@0: Author: christine@netscape.com michael@0: Date: 11 september 1997 michael@0: */ michael@0: var SECTION = "12.6.3-4"; michael@0: var VERSION = "ECMA_1"; michael@0: startTest(); michael@0: var TITLE = "The for..in statement"; michael@0: michael@0: writeHeaderToLog( SECTION + " "+ TITLE); michael@0: michael@0: // for ( LeftHandSideExpression in Expression ) michael@0: // LeftHandSideExpression:NewExpression:MemberExpression michael@0: michael@0: var count = 0; michael@0: function f() { count++; return new Array("h","e","l","l","o"); } michael@0: michael@0: var result = ""; michael@0: for ( p in f() ) { result += f()[p] }; michael@0: michael@0: new TestCase( SECTION, michael@0: "count = 0; result = \"\"; "+ michael@0: "function f() { count++; return new Array(\"h\",\"e\",\"l\",\"l\",\"o\"); }"+ michael@0: "for ( p in f() ) { result += f()[p] }; count", michael@0: 6, michael@0: count ); michael@0: michael@0: new TestCase( SECTION, michael@0: "result", michael@0: "hello", michael@0: result ); michael@0: michael@0: michael@0: michael@0: // LeftHandSideExpression:NewExpression:MemberExpression [ Expression ] michael@0: // LeftHandSideExpression:NewExpression:MemberExpression .
