compareBoundaryPoints

---

Compares the boundary points of two Ranges.

Syntax

compare = range.compareBoundaryPoints(how,sourceRange);

Parameters

The compareBoundaryPoints method takes the following parameters:

compare	A number, 1, 0, -1.
how	A constant describing the comparison method
sourceRange	A Range to boundary points with range

Example

range = document.createRange(); range.selectNode(   document.getElementsByTagName("div").item(0)); sourceRange = document.createRange(); sourceRange.selectNode(document.getElementsByTagName(   "div").item(1)); compare = range.compareBoundaryPoints(   START_TO_END,sourceRange);

Notes

END_TO_END compares the end boundary-point of sourceRange to the end boundary-point of range.

END_TO_START compares the end boundary-point of sourceRange to the start boundary-point of range.

START_TO_END compares the start boundary-point of sourceRange to the end boundary-point of range.

START_TO_START compares the start boundary-point of sourceRange to the start boundary-point of range.
