If there is no character 28 at that position, the number is NaN. 29 30 When the charCodeAt method is called with one argument 31 pos, the following steps are taken: 32 1. Call ToString, giving it the theis value as its 33 argument 34 2. Call ToInteger(pos) 35 3. Compute the number of characters in result(1). 36 4. If Result(2) is less than 0 or is not less than 37 Result(3), return NaN. 38 5. Return a value of Number type, of positive sign, whose 39 magnitude is the Unicode encoding of one character 40 from result 1, namely the characer at position Result 41 (2), where the first character in Result(1) is 42 considered to be at position 0. 43 44 Note that the charCodeAt funciton is intentionally 45 generic; it does not require that its this value be a 46 String object. Therefore it can be transferred to other 47 kinds of objects for use as a method. 48 49 Author: christine@netscape.com 50 Date: 2 october 1997 51*/ 52 var SECTION = "15.5.4.5-2"; 53 var VERSION = "ECMA_1";
