- For the particular case of a boundary within a text node containing rendered line breaks (within a
- element, for example), we need a slightly complicated approach to get the boundary's offset in
- IE. The facts:
-
- - Each line break is represented as \r in the text node's data/nodeValue properties
- - Each line break is represented as \r\n in the TextRange's 'text' property
- - The 'text' property of the TextRange does not contain trailing line breaks
-
- To get round the problem presented by the final fact above, we can use the fact that TextRange's
- moveStart() and moveEnd() methods return the actual number of characters moved, which is not
- necessarily the same as the number of characters it was instructed to move. The simplest approach is
- to use this to store the characters moved when moving both the start and end of the range to the
- start of the document body and subtracting the start offset from the end offset (the
- "move-negative-gazillion" method). However, this is extremely slow when the document is large and
- the range is near the end of it. Clearly doing the mirror image (i.e. moving the range boundaries to
- the end of the document) has the same problem.
-
- Another approach that works is to use moveStart() to move the start boundary of the range up to the
- end boundary one character at a time and incrementing a counter with the value returned by the
- moveStart() call. However, the check for whether the start boundary has reached the end boundary is
- expensive, so this method is slow (although unlike "move-negative-gazillion" is largely unaffected
- by the location of the range within the document).
-
- The approach used below is a hybrid of the two methods above. It uses the fact that a string
- containing the TextRange's 'text' property with each \r\n converted to a single \r character cannot
- be longer than the text of the TextRange, so the start of the range is moved that length initially
- and then a character at a time to make up for any trailing line breaks not contained in the 'text'
- property. This has good performance in most situations compared to the previous two methods.
