ECMA Section: 15.5.4.6 String.prototype.indexOf( searchString, pos)
|
|
Description: If the given searchString appears as a substring of the
|
|
result of converting this object to a string, at one or
|
|
more positions that are at or to the right of the
|
|
specified position, then the index of the leftmost such
|
|
position is returned; otherwise -1 is returned. If
|
|
positionis undefined or not supplied, 0 is assumed, so
|
|
as to search all of the string.
|
|
|
|
When the indexOf method is called with two arguments,
|
|
searchString and pos, the following steps are taken:
|
|
|
|
1. Call ToString, giving it the this value as its
|
|
argument.
|
|
2. Call ToString(searchString).
|
|
3. Call ToInteger(position). (If position is undefined
|
|
or not supplied, this step produces the value 0).
|
|
4. Compute the number of characters in Result(1).
|
|
5. Compute min(max(Result(3), 0), Result(4)).
|
|
6. Compute the number of characters in the string that
|
|
is Result(2).
|
|
7. Compute the smallest possible integer k not smaller
|
|
than Result(5) such that k+Result(6) is not greater
|
|
than Result(4), and for all nonnegative integers j
|
|
less than Result(6), the character at position k+j
|
|
of Result(1) is the same as the character at position
|
|
j of Result(2); but if there is no such integer k,
|
|
then compute the value -1.
|
|
8. Return Result(7).
|
|
|
|
Note that the indexOf 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.
