9 ECMA Section: 15.5.4.4 String.prototype.charAt(pos) |
|
10 Description: Returns a string containing the character at position |
|
11 pos in the string. If there is no character at that |
|
12 string, the result is the empty string. The result is |
|
13 a string value, not a String object. |
|
14 |
|
15 When the charAt method is called with one argument, |
|
16 pos, the following steps are taken: |
|
17 1. Call ToString, with this value as its argument |
|
18 2. Call ToInteger pos |
|
19 3. Compute the number of characters in Result(1) |
|
20 4. If Result(2) is less than 0 is or not less than |
|
21 Result(3), return the empty string |
|
22 5. Return a string of length 1 containing one character |
|
23 from result (1), the character at position Result(2). |
|
24 |
|
25 Note that the charAt function is intentionally generic; |
|
26 it does not require that its this value be a String |
|
27 object. Therefore it can be transferred to other kinds |
|
28 of objects for use as a method. |
|
29 |
|
30 This tests assiging charAt to primitive types.. |
