- For the particular case of a boundary within a text node containing line breaks (within a <pre> 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.

- * - We can't use HTML5 sandbox for now:

- * But then there's another problem, DOM events (focus, blur, change, keypress, ...) aren't fired.
- * In order to make this happen we need to set the "allow-scripts" flag.
- * A combination of allow-scripts and allow-same-origin is almost the same as setting no sandbox attribute at all.
- * - Chrome & Safari, doesn't seem to support sandboxing correctly when the iframe's html is inlined (no physical document)
- * - IE needs to have the security="restricted" attribute set before the iframe is
- * inserted into the dom tree
- * - Believe it or not but in IE "security" in document.createElement("iframe") is false, even
- * though it supports it
- * - When an iframe has security="restricted", in IE eval() & execScript() don't work anymore
- * - IE doesn't fire the onload event when the content is inlined in the src attribute, therefore we rely
- * on the onreadystatechange event
