If there is no character at that + string, the result is the empty string. The result is + a string value, not a String object. + + When the charAt method is called with one argument, + pos, the following steps are taken: + 1. Call ToString, with this value as its argument + 2. Call ToInteger pos + 3. Compute the number of characters in Result(1) + 4. If Result(2) is less than 0 is or not less than + Result(3), return the empty string + 5. Return a string of length 1 containing one character + from result (1), the character at position Result(2). + + Note that the charAt function is intentionally generic; + it does not require that its this value be a String + object. Therefore it can be transferred to other kinds + of objects for use as a method. + + This tests assiging charAt to a user-defined function. + + Author: christine@netscape.com + Date: 2 october 1997 +*/ + var SECTION = "15.5.4.4-3"; + var VERSION = "ECMA_1"; + startTest(); + var TITLE = "String.prototype.charAt"; + + writeHeaderToLog( SECTION + " "+ TITLE); + + var testcases = getTestCases(); + test(); + +function MyObject (v) { + this.value = v; + this.toString = new Function( "return this.value +'';" ); + this.valueOf = new Function( "return this.value" ); + this.charAt = String.prototype.charAt; +} +function getTestCases() { + var array = new Array(); + var item = 0; + + var foo = new MyObject('hello'); + + + array[item++] = new TestCase( SECTION, "var foo = new MyObject('hello'); ", "h", foo.charAt(0) ); + array[item++] = new TestCase( SECTION, "var foo = new MyObject('hello'); ", "e", foo.charAt(1) ); + array[item++] = new TestCase( SECTION, "var foo = new MyObject('hello'); ", "l", foo.charAt(2) ); + array[item++] = new TestCase( SECTION, "var foo = new MyObject('hello'); ", "l", foo.charAt(3) ); + array[item++] = new TestCase( SECTION, "var foo = new MyObject('hello'); ", "o", foo.charAt(4) ); + array[item++] = new TestCase( SECTION, "var foo = new MyObject('hello'); ", "", foo.charAt(-1) ); + array[item++] = new TestCase( SECTION, "var foo = new MyObject('hello'); ", "", foo.charAt(5) ); + + var boo = new MyObject(true); + + array[item++] = new TestCase( SECTION, "var boo = new MyObject(true); ", "t", boo.charAt(0) ); + array[item++] = new TestCase( SECTION, "var boo = new MyObject(true); ", "r", boo.charAt(1) ); + array[item++] = new TestCase( SECTION, "var boo = new MyObject(true); ", "u", boo.charAt(2) ); + array[item++] = new TestCase( SECTION, "var boo = new MyObject(true); ", "e", boo.charAt(3) ); + + var noo = new MyObject( Math.PI ); + + array[item++] = new TestCase( SECTION, "var noo = new MyObject(Math.PI); ", "3", noo.charAt(0) ); + array[item++] = new TestCase( SECTION, "var noo = new MyObject(Math.PI); ", ".", noo.charAt(1) ); + array[item++] = new TestCase( SECTION, "var noo = new MyObject(Math.PI); ", "1", noo.charAt(2) ); + array[item++] = new TestCase( SECTION, "var noo = new MyObject(Math.PI); ", "4", noo.charAt(3) ); + array[item++] = new TestCase( SECTION, "var noo = new MyObject(Math.PI); ", "1", noo.charAt(4) ); + array[item++] = new TestCase( SECTION, "var noo = new MyObject(Math.PI); ", "5", noo.charAt(5) ); + array[item++] = new TestCase( SECTION, "var noo = new MyObject(Math.PI); ", "9", noo.charAt(6) ); + + return array; +} + +function test() { + for ( tc = 0; tc < testcases.length; tc++ ) { + testcases[tc].passed = writeTestCaseResult( + testcases[tc].expect, + testcases[tc].actual, + testcases[tc].description +" = "+ + testcases[tc].actual ); + + testcases[tc].reason += ( testcases[tc].passed ) + ?
