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);

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.
