ECMA Section: 15.5.4.4 String.prototype.charAt(pos)
|
|
Description: Returns a string containing the character at position
|
|
pos in the string. If there is no character at that
|
|
string, the result is the empty string. The result is
|
|
a string value, not a String object.
|
|
|
|
When the charAt method is called with one argument,
|
|
pos, the following steps are taken:
|
|
1. Call ToString, with this 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 is or not less than
|
|
Result(3), return the empty string
|
|
5. Return a string of length 1 containing one character
|
|
from result (1), the character at position Result(2).
|
|
|
|
Note that the charAt 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.
