Each argument specifies 27 one character of the resulting string, with the first 28 argument specifying the first character, and so on, 29 from left to right. An argument is converted to a 30 character by applying the operation ToUint16 and 31 regarding the resulting 16bit integeras the Unicode 32 encoding of a character. If no arguments are supplied, 33 the result is the empty string. 34 35 This test covers Basic Latin (range U+0020 - U+007F) 36 37 Author: christine (at) netscape.com 38 Date: 2 october 1997 39 */ 40 41 var SECTION = "15.5.3.2-3"; 42 var VERSION = "ECMA_1"; 43 startTest(); 44 var TITLE = "String.fromCharCode()"; 45 46 writeHeaderToLog( SECTION + " "+ TITLE); 47 48 var testcases = getTestCases(); 49 test(); 50 51 function getTestCases() { 52 var array = new Array(); 53 var item = 0; 54 55 for ( CHARCODE = 0; CHARCODE < 256; CHARCODE++ ) { 56 array[item++] = new TestCase( SECTION, 57 "(String.fromCharCode(" + CHARCODE +")).charCodeAt(0)", 58 ToUint16(CHARCODE), 59 (String.fromCharCode(CHARCODE)).charCodeAt(0) 60 ); 61 } 62 for ( CHARCODE = 256; CHARCODE < 65536; CHARCODE+=333 ) { 63 array[item++] = new TestCase( SECTION, 64 "(String.fromCharCode(" + CHARCODE +")).charCodeAt(0)", 65 ToUint16(CHARCODE), 66 (String.fromCharCode(CHARCODE)).charCodeAt(0) 67 ); 68 } 69 for ( CHARCODE = 65535; CHARCODE < 65538; CHARCODE++ ) { 70 array[item++] = new TestCase( SECTION, 71 "(String.fromCharCode(" + CHARCODE +")).charCodeAt(0)", 72 ToUint16(CHARCODE), 73 (String.fromCharCode(CHARCODE)).charCodeAt(0) 74 ); 75 } 76 for ( CHARCODE = Math.pow(2,32)-1; CHARCODE < Math.pow(2,32)+1; CHARCODE++ ) { 77 array[item++] = new TestCase( SECTION, 78 "(String.fromCharCode(" + CHARCODE +")).charCodeAt(0)", 79 ToUint16(CHARCODE), 80 (String.fromCharCode(CHARCODE)).charCodeAt(0) 81 ); 82 } 83 for ( CHARCODE = 0; CHARCODE > -65536; CHARCODE-=3333 ) { 84 array[item++] = new TestCase( SECTION, 85 "(String.fromCharCode(" + CHARCODE +")).charCodeAt(0)", 86 ToUint16(CHARCODE), 87 (String.fromCharCode(CHARCODE)).charCodeAt(0) 88 ); 89 } 90 array[item++] = new TestCase( SECTION, "(String.fromCharCode(65535)).charCodeAt(0)", 65535, (String.fromCharCode(65535)).charCodeAt(0) ); 91 array[item++] = new TestCase( SECTION, "(String.fromCharCode(65536)).charCodeAt(0)", 0, (String.fromCharCode(65536)).charCodeAt(0) ); 92 array[item++] = new TestCase( SECTION, "(String.fromCharCode(65537)).charCodeAt(0)", 1, (String.fromCharCode(65537)).charCodeAt(0) ); 93 94 return array; 95 } 96 function ToUint16( num ) { 97 num = Number( num ); 98 if ( isNaN( num ) || num == 0 || num == Number.POSITIVE_INFINITY || num == Number.NEGATIVE_INFINITY ) { 99 return 0; 100 } 101 102 var sign = ( num < 0 ) ? -1 : 1; 103 104 num = sign * Math.floor( Math.abs( num ) ); 105 num = num % Math.pow(2,16); 106 num = ( num > -65536 && num < 0) ? 65536 + num : num; 107 return num; 108 } 109 110 function test() { 111 for ( tc=0; tc < testcases.length; tc++ ) { 112 testcases[tc].passed = writeTestCaseResult( 113 testcases[tc].expect, 114 testcases[tc].actual, 115 testcases[tc].description +" = "+ 116 testcases[tc].actual ); 117 118 testcases[tc].reason += ( testcases[tc].passed ) ?
