Each character is regarded as occupying a position 29 within the sequence. These positions are identified by nonnegative 30 integers. The leftmost character (if any) is at position 0, the next 31 character (if any) at position 1, and so on. The length of a string is the 32 number of distinct positions within it. The empty string has length zero 33 and therefore contains no characters. 34 35 Author: christine@netscape.com 36 Date: 12 november 1997 37*/ 38 39 var SECTION = "8.4"; 40 var VERSION = "ECMA_1"; 41 startTest(); 42 var TITLE = "The String type"; 43 44 writeHeaderToLog( SECTION + " "+ TITLE); 45 46 var testcases = new Array(); 47 48 testcases[tc++] = new TestCase( SECTION, 49 "var s = ''; s.length", 50 0, 51 eval("var s = ''; s.length") ); 52 53 testcases[tc++] = new TestCase( SECTION, 54 "var s = ''; s.charAt(0)", 55 "", 56 eval("var s = ''; s.charAt(0)") ); 57 58 59 for ( var i = 0x0041, TEST_STRING = "", EXPECT_STRING = ""; i < 0x007B; i++ ) { 60 TEST_STRING += ("\\u"+ DecimalToHexString( i ) ); 61 EXPECT_STRING += String.fromCharCode(i); 62 } 63 64 testcases[tc++] = new TestCase( SECTION, 65 "var s = '" + TEST_STRING+ "'; s", 66 EXPECT_STRING, 67 eval("var s = '" + TEST_STRING+ "'; s") ); 68 69 testcases[tc++] = new TestCase( SECTION, 70 "var s = '" + TEST_STRING+ "'; s.length", 71 0x007B-0x0041, 72 eval("var s = '" + TEST_STRING+ "'; s.length") ); 73 74 test(); 75function DecimalToHexString( n ) { 76 n = Number( n ); 77 var h = ""; 78 79 for ( var i = 3; i >= 0; i-- ) { 80 if ( n >= Math.pow(16, i) ){ 81 var t = Math.floor( n / Math.pow(16, i)); 82 n -= t * Math.pow(16, i); 83 if ( t >= 10 ) { 84 if ( t == 10 ) { 85 h += "A"; 86 } 87 if ( t == 11 ) { 88 h += "B"; 89 } 90 if ( t == 12 ) { 91 h += "C"; 92 } 93 if ( t == 13 ) { 94 h += "D"; 95 } 96 if ( t == 14 ) { 97 h += "E"; 98 } 99 if ( t == 15 ) { 100 h += "F"; 101 } 102 } else { 103 h += String( t ); 104 } 105 } else { 106 h += "0"; 107 } 108 } 109 110 return h; 111} 112 113function test() { 114 for ( tc=0; tc < testcases.length; tc++ ) { 115 testcases[tc].passed = writeTestCaseResult( 116 testcases[tc].expect, 117 testcases[tc].actual, 118 testcases[tc].description +" = "+ 119 testcases[tc].actual ); 120 121 testcases[tc].reason += ( testcases[tc].passed ) ?
