bsw/jbe@1309:
bsw/jbe@1309:
element, for example), we need a slightly complicated approach to get the boundary's offset in bsw/jbe@1309: IE. The facts: bsw/jbe@1309: bsw/jbe@1309: - Each line break is represented as \r in the text node's data/nodeValue properties bsw/jbe@1309: - Each line break is represented as \r\n in the TextRange's 'text' property bsw/jbe@1309: - The 'text' property of the TextRange does not contain trailing line breaks bsw/jbe@1309: bsw/jbe@1309: To get round the problem presented by the final fact above, we can use the fact that TextRange's bsw/jbe@1309: moveStart() and moveEnd() methods return the actual number of characters moved, which is not bsw/jbe@1309: necessarily the same as the number of characters it was instructed to move. The simplest approach is bsw/jbe@1309: to use this to store the characters moved when moving both the start and end of the range to the bsw/jbe@1309: start of the document body and subtracting the start offset from the end offset (the bsw/jbe@1309: "move-negative-gazillion" method). However, this is extremely slow when the document is large and bsw/jbe@1309: the range is near the end of it. Clearly doing the mirror image (i.e. moving the range boundaries to bsw/jbe@1309: the end of the document) has the same problem. bsw/jbe@1309: bsw/jbe@1309: Another approach that works is to use moveStart() to move the start boundary of the range up to the bsw/jbe@1309: end boundary one character at a time and incrementing a counter with the value returned by the bsw/jbe@1309: moveStart() call. However, the check for whether the start boundary has reached the end boundary is bsw/jbe@1309: expensive, so this method is slow (although unlike "move-negative-gazillion" is largely unaffected bsw/jbe@1309: by the location of the range within the document). bsw/jbe@1309: bsw/jbe@1309: The approach used below is a hybrid of the two methods above. It uses the fact that a string bsw/jbe@1309: containing the TextRange's 'text' property with each \r\n converted to a single \r character cannot bsw/jbe@1309: be longer than the text of the TextRange, so the start of the range is moved that length initially bsw/jbe@1309: and then a character at a time to make up for any trailing line breaks not contained in the 'text' bsw/jbe@1309: property.
