Thus, the function call Array(...) is 29 equivalent to the object creation new Array(...) with 30 the same arguments. 31 32 An array is created and returned as if by the expression 33 new Array( item0, item1, ... ). 34 35 Author: christine (at) netscape.com 36 Date: 7 october 1997 37 */ 38 var SECTION = "15.4.1.1"; 39 var VERSION = "ECMA_1"; 40 startTest(); 41 var TITLE = "Array Constructor Called as a Function"; 42 43 writeHeaderToLog( SECTION + " "+ TITLE); 44 45 var testcases = getTestCases(); 46 test(); 47 48 function ToUint32( n ) { 49 n = Number( n ); 50 if( isNaN(n) || n == 0 || n == Number.POSITIVE_INFINITY || 51 n == Number.NEGATIVE_INFINITY ) { 52 return 0; 53 } 54 var sign = n < 0 ? -1 : 1; 55 56 return ( sign * ( n * Math.floor( Math.abs(n) ) ) ) % Math.pow(2, 32); 57 } 58 59 function getTestCases() { 60 var array = new Array(); 61 var item = 0; 62 63 array[item++] = new TestCase( SECTION, "typeof Array(1,2)", "object", typeof Array(1,2) ); 64 array[item++] = new TestCase( SECTION, "(Array(1,2)).toString", Array.prototype.toString, (Array(1,2)).toString ); 65 array[item++] = new TestCase( SECTION, 66 "var arr = Array(1,2,3); arr.toString = Object.prototype.toString; arr.toString()", 67 "[object Array]", 68 eval("var arr = Array(1,2,3); arr.toString = Object.prototype.toString; arr.toString()") ); 69 70 71 array[item++] = new TestCase( SECTION, "(Array(1,2)).length", 2, (Array(1,2)).length ); 72 array[item++] = new TestCase( SECTION, "var arr = (Array(1,2)); arr[0]", 1, eval("var arr = (Array(1,2)); arr[0]") ); 73 array[item++] = new TestCase( SECTION, "var arr = (Array(1,2)); arr[1]", 2, eval("var arr = (Array(1,2)); arr[1]") ); 74 array[item++] = new TestCase( SECTION, "var arr = (Array(1,2)); String(arr)", "1,2", eval("var arr = (Array(1,2)); String(arr)") ); 75 76 return ( array ); 77 } 78 function test() { 79 for ( tc=0; tc < testcases.length; tc++ ) { 80 testcases[tc].passed = writeTestCaseResult( 81 testcases[tc].expect, 82 testcases[tc].actual, 83 testcases[tc].description +" = "+ testcases[tc].actual ); 84 testcases[tc].reason += ( testcases[tc].passed ) ?
