| michael@0 | 8 | File Name: 15.5.4.5.1.js |
| michael@0 | 9 | ECMA Section: 15.5.4.5 String.prototype.charCodeAt(pos) |
| michael@0 | 10 | Description: Returns a number (a nonnegative integer less than 2^16) |
| michael@0 | 11 | representing the Unicode encoding of the character at |
| michael@0 | 12 | position pos in this string. If there is no character |
| michael@0 | 13 | at that position, the number is NaN. |
| michael@0 | 14 | |
| michael@0 | 15 | When the charCodeAt method is called with one argument |
| michael@0 | 16 | pos, the following steps are taken: |
| michael@0 | 17 | 1. Call ToString, giving it the theis value as its |
| michael@0 | 18 | argument |
| michael@0 | 19 | 2. Call ToInteger(pos) |
| michael@0 | 20 | 3. Compute the number of characters in result(1). |
| michael@0 | 21 | 4. If Result(2) is less than 0 or is not less than |
| michael@0 | 22 | Result(3), return NaN. |
| michael@0 | 23 | 5. Return a value of Number type, of positive sign, whose |
| michael@0 | 24 | magnitude is the Unicode encoding of one character |
| michael@0 | 25 | from result 1, namely the characer at position Result |
| michael@0 | 26 | (2), where the first character in Result(1) is |
| michael@0 | 27 | considered to be at position 0. |
| michael@0 | 28 | |
| michael@0 | 29 | Note that the charCodeAt function is intentionally |
| michael@0 | 30 | generic; it does not require that its this value be a |
| michael@0 | 31 | String object. Therefore it can be transferred to other |
| michael@0 | 32 | kinds of objects for use as a method. |
