From ae38caba31636226f93b0d00ebda1ab6a8e3e8b5 Mon Sep 17 00:00:00 2001 From: Neil Jenkins Date: Sat, 29 Nov 2014 20:08:53 +0700 Subject: [PATCH] Remove IE8 support. It was always a bit buggy, and realistically there's no point in putting in the time to fix it up. --- Demo.html | 3 - Makefile | 8 +- Readme.md | 6 +- build/document.html | 5 +- build/ie8.js | 1 -

 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 method 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.
