If 30 there is no calling context, then initializing the scope chain, variable 31 instantiation, and determination of the this value are performed just as 32 for global code. 33 34 The scope chain is initialized to contain the same objects, in the same 35 order, as the calling context's scope chain. This includes objects added 36 to the calling context's scope chain by WithStatement. 37 38 Variable instantiation is performed using the calling context's variable 39 object and using empty property attributes. 40 41 The this value is the same as the this value of the calling context. 42 43 Author: christine@netscape.com 44 Date: 12 november 1997 45*/ 46 47 var SECTION = "10.2.2-2"; 48 var VERSION = "ECMA_1"; 49 startTest(); 50 var TITLE = "Eval Code"; 51 52 writeHeaderToLog( SECTION + " "+ TITLE); 53 54 var testcases = new Array(); 55 56 // Test Objects 57 58 var OBJECT = new MyObject( "hello" ); 59 var GLOBAL_PROPERTIES = new Array(); 60 var i = 0; 61 62 for ( p in this ) { 63 GLOBAL_PROPERTIES[i++] = p; 64 } 65 66 with ( OBJECT ) { 67 var THIS = this; 68 testcases[tc++] = new TestCase( SECTION, "eval( 'this == THIS' )", true, eval("this == THIS") ); 69 testcases[tc++] = new TestCase( SECTION, "this in a with() block", GLOBAL, this+"" ); 70 testcases[tc++] = new TestCase( SECTION, "new MyObject('hello').value", "hello", value ); 71 testcases[tc++] = new TestCase( SECTION, "eval(new MyObject('hello').value)", "hello", eval("value") ); 72 testcases[tc++] = new TestCase( SECTION, "new MyObject('hello').getClass()", "[object Object]", getClass() ); 73 testcases[tc++] = new TestCase( SECTION, "eval(new MyObject('hello').getClass())", "[object Object]", eval("getClass()") ); 74 testcases[tc++] = new TestCase( SECTION, "eval(new MyObject('hello').toString())", "hello", eval("toString()") ); 75 testcases[tc++] = new TestCase( SECTION, "eval('getClass') == Object.prototype.toString", true, eval("getClass") == Object.prototype.toString ); 76 77 for ( i = 0; i < GLOBAL_PROPERTIES.length; i++ ) { 78 testcases[tc++] = new TestCase( SECTION, GLOBAL_PROPERTIES[i] + 79 " == THIS["+GLOBAL_PROPERTIES[i]+"]", true, 80 eval(GLOBAL_PROPERTIES[i]) == eval( "THIS[GLOBAL_PROPERTIES[i]]") ); 81 } 82 83 } 84 85 test(); 86 87function test() { 88 for ( tc=0; tc < testcases.length; tc++ ) { 89 testcases[tc].passed = writeTestCaseResult( 90 testcases[tc].expect, 91 testcases[tc].actual, 92 testcases[tc].description +" = "+ 93 testcases[tc].actual ); 94 95 testcases[tc].reason += ( testcases[tc].passed ) ?
