/*
|

|
|
For the particular case of a boundary within a text node containing rendered 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 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.

|
|||
|
|
* - sandboxing of physical documents causes that the dom isn't accessible anymore from the outside (iframe.contentWindow, ...)
|
|||
|
|
* - 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
