Call the [[Get]] method of this object with argument "length". 1.19 + 2. Call ToUint32(Result(1)). 1.20 + 3. Compute floor(Result(2)/2). 1.21 + 4. Let k be 0. 1.22 + 5. If k equals Result(3), return this object. 1.23 + 6. Compute Result(2)k1. 1.24 + 7. Call ToString(k). 1.25 + 8. ToString(Result(6)). 1.26 + 9. Call the [[Get]] method of this object with argument Result(7). 1.27 + 10. Call the [[Get]] method of this object with argument Result(8). 1.28 + 11. If this object has a property named by Result(8), go to step 12; but 1.29 + if this object has no property named by Result(8), then go to either 1.30 + step 12 or step 14, depending on the implementation. 1.31 + 12. Call the [[Put]] method of this object with arguments Result(7) and 1.32 + Result(10). 1.33 + 13. Go to step 15. 1.34 + 14. Call the [[Delete]] method on this object, providing Result(7) as the 1.35 + name of the property to delete. 1.36 + 15. If this object has a property named by Result(7), go to step 16; but if 1.37 + this object has no property named by Result(7), then go to either step 16 1.38 + or step 18, depending on the implementation. 1.39 + 16. Call the [[Put]] method of this object with arguments Result(8) and 1.40 + Result(9). 1.41 + 17. Go to step 19. 1.42 + 18. Call the [[Delete]] method on this object, providing Result(8) as the 1.43 + name of the property to delete. 1.44 + 19. Increase k by 1. 1.45 + 20. Go to step 5. 1.46 + 1.47 + Note that the reverse function is intentionally generic; it does not require 1.48 + that its this value be an Array object. Therefore it can be transferred to other 1.49 + kinds of objects for use as a method. Whether the reverse function can be applied 1.50 + successfully to a host object is implementation dependent. 1.51 + 1.52 + Note: Array.prototype.reverse allows some flexibility in implementation 1.53 + regarding array indices that have not been populated. This test covers the 1.54 + cases in which unpopulated indices are not deleted, since the JavaScript 1.55 + implementation does not delete uninitialzed indices. 1.56 + 1.57 + Author: christine@netscape.com 1.58 + Date: 7 october 1997 1.59 +*/ 1.60 + 1.61 +var SECTION = "15.4.4.4-1"; 1.62 +var VERSION = "ECMA_1"; 1.63 +startTest(); 1.64 + 1.65 +writeHeaderToLog( SECTION + " Array.prototype.reverse()"); 1.66 + 1.67 +var ARR_PROTOTYPE = Array.prototype; 1.68 + 1.69 +new TestCase( SECTION, "Array.prototype.reverse.length", 0, Array.prototype.reverse.length ); 1.70 +new TestCase( SECTION, "delete Array.prototype.reverse.length", false, delete Array.prototype.reverse.length ); 1.71 +new TestCase( SECTION, "delete Array.prototype.reverse.length; Array.prototype.reverse.length", 0, eval("delete Array.prototype.reverse.length; Array.prototype.reverse.length") ); 1.72 + 1.73 +// length of array is 0 1.74 +new TestCase( SECTION, 1.75 + "var A = new Array(); A.reverse(); A.length", 1.76 + 0, 1.77 + eval("var A = new Array(); A.reverse(); A.length") ); 1.78 + 1.79 +test(); 1.80 + 1.81 +function CheckItems( R, A ) { 1.82 + for ( var i = 0; i < R.length; i++ ) { 1.83 + new TestCase( 1.84 + SECTION, 1.85 + "A["+i+ "]", 1.86 + R[i], 1.87 + A[i] ); 1.88 + } 1.89 +} 1.90 +test(); 1.91 + 1.92 +function Object_1( value ) { 1.93 + this.array = value.split(","); 1.94 + this.length = this.array.length; 1.95 + for ( var i = 0; i < this.length; i++ ) { 1.96 + this[i] = eval(this.array[i]); 1.97 + } 1.98 + this.join = Array.prototype.reverse; 1.99 + this.getClass = Object.prototype.toString; 1.100 +} 1.101 +function Reverse( array ) { 1.102 + var r2 = array.length; 1.103 + var k = 0; 1.104 + var r3 = Math.floor( r2/2 ); 1.105 + if ( r3 == k ) { 1.106 + return array; 1.107 + } 1.108 + 1.109 + for ( k = 0; k < r3; k++ ) { 1.110 + var r6 = r2 - k - 1; 1.111 +// var r7 = String( k ); 1.112 + var r7 = k; 1.113 + var r8 = String( r6 ); 1.114 + 1.115 + var r9 = array[r7]; 1.116 + var r10 = array[r8]; 1.117 + 1.118 + array[r7] = r10; 1.119 + array[r8] = r9; 1.120 + } 1.121 + 1.122 + return array; 1.123 +} 1.124 +function Iterate( array ) { 1.125 + for ( var i = 0; i < array.length; i++ ) { 1.126 +// print( i+": "+ array[String(i)] ); 1.127 + } 1.128 +} 1.129 + 1.130 +function Object_1( value ) { 1.131 + this.array = value.split(","); 1.132 + this.length = this.array.length; 1.133 + for ( var i = 0; i < this.length; i++ ) { 1.134 + this[i] = this.array[i]; 1.135 + } 1.136 + this.reverse = Array.prototype.reverse; 1.137 + this.getClass = Object.prototype.toString; 1.138 +}
