|
1990 |
+ For the particular case of a boundary within a text node containing line breaks (within a <pre> element, |
|
1991 |
+ for example), we need a slightly complicated approach to get the boundary's offset in IE. The facts: |
|
1992 |
+ |
|
1993 |
+ - Each line break is represented as \r in the text node's data/nodeValue properties |
|
1994 |
+ - Each line break is represented as \r\n in the TextRange's 'text' property |
|
1995 |
+ - The 'text' property of the TextRange does not contain trailing line breaks |
|
1996 |
+ |
|
1997 |
+ To get round the problem presented by the final fact above, we can use the fact that TextRange's |
|
1998 |
+ moveStart() and moveEnd() methods return the actual number of characters moved, which is not necessarily |
|
1999 |
+ the same as the number of characters it was instructed to move. The simplest approach is to use this to |
|
2000 |
+ store the characters moved when moving both the start and end of the range to the start of the document |
|
2001 |
+ body and subtracting the start offset from the end offset (the "move-negative-gazillion" method). |
|
2002 |
+ However, this is extremely slow when the document is large and the range is near the end of it. Clearly |
|
2003 |
+ doing the mirror image (i.e. moving the range boundaries to the end of the document) has the same |
|
2004 |
+ problem. |
|
2005 |
+ |
|
2006 |
+ Another approach that works is to use moveStart() to move the start boundary of the range up to the end |
|
2007 |
+ boundary one character at a time and incrementing a counter with the value returned by the moveStart() |
|
2008 |
+ call. However, the check for whether the start boundary has reached the end boundary is expensive, so |
|
2009 |
+ this method is slow (although unlike "move-negative-gazillion" is largely unaffected by the location of |
|
2010 |
+ the range within the document). |
|
2011 |
+ |
|
2012 |
+ The method below is a hybrid of the two methods above. It uses the fact that a string containing the |
|
2013 |
+ TextRange's 'text' property with each \r\n converted to a single \r character cannot be longer than the |
|
2014 |
+ text of the TextRange, so the start of the range is moved that length initially and then a character at |
|
2015 |
+ a time to make up for any trailing line breaks not contained in the 'text' property. This has good |
|
2016 |
+ performance in most situations compared to the previous two methods. |

|
5303 |
+ * - sandboxing of physical documents causes that the dom isn't accessible anymore from the outside (iframe.contentWindow, ...) |
|
5304 |
+ * - setting the "allow-same-origin" flag would fix that, but then still javascript and dom events refuse to fire |
|
5305 |
+ * - therefore the "allow-scripts" flag is needed, which then would deactivate any security, as the js executed inside the iframe |
|

|
5387 |
+ * - We can't use HTML5 sandbox for now: |
|
5388 |
+ * setting it causes that the iframe's dom can't be accessed from the outside |
|
5389 |
+ * Therefore we need to set the "allow-same-origin" flag which enables accessing the iframe's dom |
|
5390 |
+ * But then there's another problem, DOM events (focus, blur, change, keypress, ...) aren't fired. |
|
5391 |
+ * In order to make this happen we need to set the "allow-scripts" flag. |
|
5392 |
+ * A combination of allow-scripts and allow-same-origin is almost the same as setting no sandbox attribute at all. |
|
5393 |
+ * - Chrome & Safari, doesn't seem to support sandboxing correctly when the iframe's html is inlined (no physical document) |
|
5394 |
+ * - IE needs to have the security="restricted" attribute set before the iframe is |
|
5395 |
+ * inserted into the dom tree |
|
5396 |
+ * - Believe it or not but in IE "security" in document.createElement("iframe") is false, even |
|
5397 |
+ * though it supports it |
|
5398 |
+ * - When an iframe has security="restricted", in IE eval() & execScript() don't work anymore |
|
5399 |
+ * - IE doesn't fire the onload event when the content is inlined in the src attribute, therefore we rely |
|
5400 |
+ * on the onreadystatechange event |
