| 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. |
