Get the [[Class]] property of this object 29 2. Call ToString( Result(1) ) 30 3. Compute a string value by concatenating the three 31 strings "[object " + Result(2) + "]" 32 4. Return Result(3). 33 34 Author: christine (at) netscape.com 35 Date: 28 october 1997 36 37 */ 38 var SECTION = "15.2.4.2"; 39 var VERSION = "ECMA_1"; 40 startTest(); 41 var TITLE = "Object.prototype.toString()"; 42 43 writeHeaderToLog( SECTION + " "+ TITLE); 44 45 var testcases = getTestCases(); 46 test(); 47 48 function getTestCases() { 49 var array = new Array(); 50 var item = 0; 51 52 array[item++] = new TestCase( SECTION, "(new Object()).toString()", "[object Object]", (new Object()).toString() ); 53 54 array[item++] = new TestCase( SECTION, "myvar = this; myvar.toString = Object.prototype.toString; myvar.toString()", 55 GLOBAL, 56 eval("myvar = this; myvar.toString = Object.prototype.toString; myvar.toString()") ); 57 58 array[item++] = new TestCase( SECTION, "myvar = MyObject; myvar.toString = Object.prototype.toString; myvar.toString()", 59 "[object Function]", 60 eval("myvar = MyObject; myvar.toString = Object.prototype.toString; myvar.toString()") ); 61 62 array[item++] = new TestCase( SECTION, "myvar = new MyObject( true ); myvar.toString = Object.prototype.toString; myvar.toString()", 63 '[object Object]', 64 eval("myvar = new MyObject( true ); myvar.toString = Object.prototype.toString; myvar.toString()") ); 65 66 array[item++] = new TestCase( SECTION, "myvar = new Number(0); myvar.toString = Object.prototype.toString; myvar.toString()", 67 "[object Number]", 68 eval("myvar = new Number(0); myvar.toString = Object.prototype.toString; myvar.toString()") ); 69 70 array[item++] = new TestCase( SECTION, "myvar = new String(''); myvar.toString = Object.prototype.toString; myvar.toString()", 71 "[object String]", 72 eval("myvar = new String(''); myvar.toString = Object.prototype.toString; myvar.toString()") ); 73 74 array[item++] = new TestCase( SECTION, "myvar = Math; myvar.toString = Object.prototype.toString; myvar.toString()", 75 "[object Math]", 76 eval("myvar = Math; myvar.toString = Object.prototype.toString; myvar.toString()") ); 77 78 array[item++] = new TestCase( SECTION, "myvar = new Function(); myvar.toString = Object.prototype.toString; myvar.toString()", 79 "[object Function]", 80 eval("myvar = new Function(); myvar.toString = Object.prototype.toString; myvar.toString()") ); 81 82 array[item++] = new TestCase( SECTION, "myvar = new Array(); myvar.toString = Object.prototype.toString; myvar.toString()", 83 "[object Array]", 84 eval("myvar = new Array(); myvar.toString = Object.prototype.toString; myvar.toString()") ); 85 86 array[item++] = new TestCase( SECTION, "myvar = new Boolean(); myvar.toString = Object.prototype.toString; myvar.toString()", 87 "[object Boolean]", 88 eval("myvar = new Boolean(); myvar.toString = Object.prototype.toString; myvar.toString()") ); 89 90 array[item++] = new TestCase( SECTION, "myvar = new Date(); myvar.toString = Object.prototype.toString; myvar.toString()", 91 "[object Date]", 92 eval("myvar = new Date(); myvar.toString = Object.prototype.toString; myvar.toString()") ); 93 94 array[item++] = new TestCase( SECTION, "var MYVAR = new Object( this ); MYVAR.toString()", 95 GLOBAL, 96 eval("var MYVAR = new Object( this ); MYVAR.toString()") ); 97 98 array[item++] = new TestCase( SECTION, "var MYVAR = new Object(); MYVAR.toString()", 99 "[object Object]", 100 eval("var MYVAR = new Object(); MYVAR.toString()") ); 101 102 array[item++] = new TestCase( SECTION, "var MYVAR = new Object(void 0); MYVAR.toString()", 103 "[object Object]", 104 eval("var MYVAR = new Object(void 0); MYVAR.toString()") ); 105 106 array[item++] = new TestCase( SECTION, "var MYVAR = new Object(null); MYVAR.toString()", 107 "[object Object]", 108 eval("var MYVAR = new Object(null); MYVAR.toString()") ); 109 110 return ( array ); 111 } 112 function test( array ) { 113 for ( tc=0 ; tc < testcases.length; tc++ ) { 114 testcases[tc].passed = writeTestCaseResult( 115 testcases[tc].expect, 116 testcases[tc].actual, 117 testcases[tc].description +" = "+ testcases[tc].actual ); 118 119 testcases[tc].reason += ( testcases[tc].passed ) ?
