About
+
Squire is an HTML5 rich text editor, which provides powerful cross-browser normalisation, whilst being supremely lightweight and flexible. It is built for the present and the future, and as such does not support truly ancient browsers. It should work fine back to around Opera 10, Firefox 3.5, Safari 4, Chrome 9 and IE8.
+
+
+
+
Unlike other HTML5 rich text editors, Squire was written as a component for writing documents (emails, essays, etc.), not doing wysiwyg websites. If you are looking for support for inserting form controls or flash components or the like, you'll need to look elsewhere. However for many purposes, Squire may be just what you need, providing the power without the bloat.

+
+
+
+
Installation
+
+ - Download the source from neilj/Squire
+ - Copy the contents of the
build/ directory onto your
+ server.
+
+ - Edit the
<style> block in document.html to add the
+ default styles you would like the editor to use (or link to an external
+ stylesheet).
+
+ - In your application, instead of a
<textarea>, use an
+ <iframe src="path/to/document.html">.
+
+ - In your JS, attach an event listener to the
load event of
+ the iframe. When this fires you can grab a reference to the editor object
+ through iframe.contentWindow.editor.
+
+ - Use the API below with the
editor object to set and get
+ data and integrate with your application or framework.

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