If there is no character + at that position, the number is NaN. + + When the charCodeAt method is called with one argument + pos, the following steps are taken: + 1. Call ToString, giving it the theis 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 or is not less than + Result(3), return NaN. + 5. Return a value of Number type, of positive sign, whose + magnitude is the Unicode encoding of one character + from result 1, namely the characer at position Result + (2), where the first character in Result(1) is + considered to be at position 0. + + Note that the charCodeAt 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. + + Author: christine@netscape.com + Date: 2 october 1997 +*/ +var SECTION = "15.5.4.5-3"; +var VERSION = "ECMA_1"; +startTest(); +var TITLE = "String.prototype.charCodeAt"; + +writeHeaderToLog( SECTION + " "+ TITLE); + +var TEST_STRING = new String( " !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~" ); + + +var foo = new MyObject('hello'); + +new TestCase( SECTION, "var foo = new MyObject('hello');foo.charCodeAt(0)", 0x0068, foo.charCodeAt(0) ); +new TestCase( SECTION, "var foo = new MyObject('hello');foo.charCodeAt(1)", 0x0065, foo.charCodeAt(1) ); +new TestCase( SECTION, "var foo = new MyObject('hello');foo.charCodeAt(2)", 0x006c, foo.charCodeAt(2) ); +new TestCase( SECTION, "var foo = new MyObject('hello');foo.charCodeAt(3)", 0x006c, foo.charCodeAt(3) ); +new TestCase( SECTION, "var foo = new MyObject('hello');foo.charCodeAt(4)", 0x006f, foo.charCodeAt(4) ); +new TestCase( SECTION, "var foo = new MyObject('hello');foo.charCodeAt(-1)", Number.NaN, foo.charCodeAt(-1) ); +new TestCase( SECTION, "var foo = new MyObject('hello');foo.charCodeAt(5)", Number.NaN, foo.charCodeAt(5) ); + +var boo = new MyObject(true); + +new TestCase( SECTION, "var boo = new MyObject(true);boo.charCodeAt(0)", 0x0074, boo.charCodeAt(0) ); +new TestCase( SECTION, "var boo = new MyObject(true);boo.charCodeAt(1)", 0x0072, boo.charCodeAt(1) ); +new TestCase( SECTION, "var boo = new MyObject(true);boo.charCodeAt(2)", 0x0075, boo.charCodeAt(2) ); +new TestCase( SECTION, "var boo = new MyObject(true);boo.charCodeAt(3)", 0x0065, boo.charCodeAt(3) ); + +var noo = new MyObject( Math.PI ); + +new TestCase( SECTION, "var noo = new MyObject(Math.PI);noo.charCodeAt(0)", 0x0033, noo.charCodeAt(0) ); +new TestCase( SECTION, "var noo = new MyObject(Math.PI);noo.charCodeAt(1)", 0x002E, noo.charCodeAt(1) ); +new TestCase( SECTION, "var noo = new MyObject(Math.PI);noo.charCodeAt(2)", 0x0031, noo.charCodeAt(2) ); +new TestCase( SECTION, "var noo = new MyObject(Math.PI);noo.charCodeAt(3)", 0x0034, noo.charCodeAt(3) ); +new TestCase( SECTION, "var noo = new MyObject(Math.PI);noo.charCodeAt(4)", 0x0031, noo.charCodeAt(4) ); +new TestCase( SECTION, "var noo = new MyObject(Math.PI);noo.charCodeAt(5)", 0x0035, noo.charCodeAt(5) ); +new TestCase( SECTION, "var noo = new MyObject(Math.PI);noo.charCodeAt(6)", 0x0039, noo.charCodeAt(6) ); + +var noo = new MyObject( null ); + +new TestCase( SECTION, "var noo = new MyObject(null);noo.charCodeAt(0)", 0x006E, noo.charCodeAt(0) ); +new TestCase( SECTION, "var noo = new MyObject(null);noo.charCodeAt(1)", 0x0075, noo.charCodeAt(1) ); +new TestCase( SECTION, "var noo = new MyObject(null);noo.charCodeAt(2)", 0x006C, noo.charCodeAt(2) ); +new TestCase( SECTION, "var noo = new MyObject(null);noo.charCodeAt(3)", 0x006C, noo.charCodeAt(3) ); +new TestCase( SECTION, "var noo = new MyObject(null);noo.charCodeAt(4)", NaN, noo.charCodeAt(4) ); + +var noo = new MyObject( void 0 ); + +new TestCase( SECTION, "var noo = new MyObject(void 0);noo.charCodeAt(0)", 0x0075, noo.charCodeAt(0) ); +new TestCase( SECTION, "var noo = new MyObject(void 0);noo.charCodeAt(1)", 0x006E, noo.charCodeAt(1) ); +new TestCase( SECTION, "var noo = new MyObject(void 0);noo.charCodeAt(2)", 0x0064, noo.charCodeAt(2) ); +new TestCase( SECTION, "var noo = new MyObject(void 0);noo.charCodeAt(3)", 0x0065, noo.charCodeAt(3) ); +new TestCase( SECTION, "var noo = new MyObject(void 0);noo.charCodeAt(4)", 0x0066, noo.charCodeAt(4) ); + +test(); + + +function MyObject (v) { + this.value = v; + this.toString = new Function ( "return this.value +\"\"" ); + this.charCodeAt = String.prototype.charCodeAt; +} |
