michael@0 | 8 | File Name: 15.5.4.6-1.js |
michael@0 | 9 | ECMA Section: 15.5.4.6 String.prototype.indexOf( searchString, pos) |
michael@0 | 10 | Description: If the given searchString appears as a substring of the |
michael@0 | 11 | result of converting this object to a string, at one or |
michael@0 | 12 | more positions that are at or to the right of the |
michael@0 | 13 | specified position, then the index of the leftmost such |
michael@0 | 14 | position is returned; otherwise -1 is returned. If |
michael@0 | 15 | positionis undefined or not supplied, 0 is assumed, so |
michael@0 | 16 | as to search all of the string. |
michael@0 | 17 | |
michael@0 | 18 | When the indexOf method is called with two arguments, |
michael@0 | 19 | searchString and pos, the following steps are taken: |
michael@0 | 20 | |
michael@0 | 21 | 1. Call ToString, giving it the this value as its |
michael@0 | 22 | argument. |
michael@0 | 23 | 2. Call ToString(searchString). |
michael@0 | 24 | 3. Call ToInteger(position). (If position is undefined |
michael@0 | 25 | or not supplied, this step produces the value 0). |
michael@0 | 26 | 4. Compute the number of characters in Result(1). |
michael@0 | 27 | 5. Compute min(max(Result(3), 0), Result(4)). |
michael@0 | 28 | 6. Compute the number of characters in the string that |
michael@0 | 29 | is Result(2). |
michael@0 | 30 | 7. Compute the smallest possible integer k not smaller |
michael@0 | 31 | than Result(5) such that k+Result(6) is not greater |
michael@0 | 32 | than Result(4), and for all nonnegative integers j |
michael@0 | 33 | less than Result(6), the character at position k+j |
michael@0 | 34 | of Result(1) is the same as the character at position |
michael@0 | 35 | j of Result(2); but if there is no such integer k, |
michael@0 | 36 | then compute the value -1. |
michael@0 | 37 | 8. Return Result(7). |
michael@0 | 38 | |
michael@0 | 39 | Note that the indexOf function is intentionally generic; |
michael@0 | 40 | it does not require that its this value be a String object. |
michael@0 | 41 | Therefore it can be transferred to other kinds of objects |
michael@0 | 42 | for use as a method. |
