Therefore it cannot be transferred 31 to other kinds of objects for use as a method. 32 33 Author: christine@netscape.com 34 Date: 12 november 1997 35*/ 36 37 var SECTION = "15.9.5.3-1-n"; 38 var VERSION = "ECMA_1"; 39 startTest(); 40 var TITLE = "Date.prototype.valueOf"; 41 42 writeHeaderToLog( SECTION + " "+ TITLE); 43 44 var testcases = new Array(); 45 46 var OBJ = new MyObject( new Date(0) ); 47 48 testcases[tc++] = new TestCase( SECTION, 49 "var OBJ = new MyObject( new Date(0) ); OBJ.valueOf()", 50 "error", 51 OBJ.valueOf() ); 52 test(); 53 54function MyObject( value ) { 55 this.value = value; 56 this.valueOf = Date.prototype.valueOf; 57// The following line causes an infinte loop 58// this.toString = new Function( "return this+\"\";"); 59 return this; 60} 61function test() { 62 for ( tc=0; tc < testcases.length; tc++ ) { 63 testcases[tc].passed = writeTestCaseResult( 64 testcases[tc].expect, 65 testcases[tc].actual, 66 testcases[tc].description +" = "+ 67 testcases[tc].actual ); 68 69 testcases[tc].reason += ( testcases[tc].passed ) ?
