/*
|
|
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.

* - setting the "allow-same-origin" flag would fix that, but then still javascript and dom events refuse to fire
|
|
* - therefore the "allow-scripts" flag is needed, which then would deactivate any security, as the js executed inside the iframe

* Creates the sandbox iframe
|

|
|
* Some important notes:
|
|
* - We can't use HTML5 sandbox for now:
|
|
* setting it causes that the iframe's dom can't be accessed from the outside
|
|
* Therefore we need to set the "allow-same-origin" flag which enables accessing the iframe's dom
|
|
* 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
