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 = "15.5.4.5-5"; +var VERSION = "ECMA_1"; +startTest(); +var TITLE = "String.prototype.charCodeAt"; + +writeHeaderToLog( SECTION + " "+ TITLE); + +var TEST_STRING = ""; + +for ( var i = 0x0000; i < 255; i++ ) { + TEST_STRING += String.fromCharCode( i ); +} + +new TestCase( SECTION, "x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(0)", 0x0074, eval("x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(0)") ); +new TestCase( SECTION, "x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(1)", 0x0072, eval("x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(1)") ); +new TestCase( SECTION, "x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(2)", 0x0075, eval("x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(2)") ); +new TestCase( SECTION, "x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(3)", 0x0065, eval("x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(3)") ); +new TestCase( SECTION, "x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(4)", Number.NaN, eval("x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(4)") ); +new TestCase( SECTION, "x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(-1)", Number.NaN, eval("x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(-1)") ); + +new TestCase( SECTION, "x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(true)", 0x0072, eval("x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(true)") ); +new TestCase( SECTION, "x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(false)", 0x0074, eval("x = new Boolean(true); x.charCodeAt=String.prototype.charCodeAt;x.charCodeAt(false)") ); + +new TestCase( SECTION, "x = new String(); x.charCodeAt(0)", Number.NaN, eval("x=new String();x.charCodeAt(0)") ); +new TestCase( SECTION, "x = new String(); x.charCodeAt(1)", Number.NaN, eval("x=new String();x.charCodeAt(1)") ); +new TestCase( SECTION, "x = new String(); x.charCodeAt(-1)", Number.NaN, eval("x=new String();x.charCodeAt(-1)") ); + +new TestCase( SECTION, "x = new String(); x.charCodeAt(NaN)", Number.NaN, eval("x=new String();x.charCodeAt(Number.NaN)") ); +new TestCase( SECTION, "x = new String(); x.charCodeAt(Number.POSITIVE_INFINITY)", Number.NaN, eval("x=new String();x.charCodeAt(Number.POSITIVE_INFINITY)") ); +new TestCase( SECTION, "x = new String(); x.charCodeAt(Number.NEGATIVE_INFINITY)", Number.NaN, eval("x=new String();x.charCodeAt(Number.NEGATIVE_INFINITY)") ); + +for ( var j = 0; j < 255; j++ ) { + new TestCase( SECTION, "TEST_STRING.charCodeAt("+j+")", j, TEST_STRING.charCodeAt(j) ); +} + +test(); |
