Just return a boolean for the TreeWalker filter fn. This diverges from the spec, but since the goal of this implementation is not to fully implement the spec and we're never going to use a native implementation, this doesn't matter and the code is easier to read when the function is just returning a boolean like any normal filter function. --- build/squire-raw.js | 36 +++++++++++------------------------- build/squire.js | 4 ++-- source/Constants.js | 2 -- source/Editor.js | 17 ++++++----------- source/Node.js | 7 +------ source/Range.js | 5 ++--- source/TreeWalker.js | 5 ++--- 7 files changed, 24 insertions(+), 52 deletions(-) diff --git a/build/squire-raw.js b/build/squire-raw.js index db27524..a3532cb 100644 --- a/build/squire-raw.js +++ b/build/squire-raw.js @@ -11,8 +11,6 @@ var ELEMENT_NODE = 1; // Node.ELEMENT_NODE; var TEXT_NODE = 3; // Node.TEXT_NODE; var SHOW_ELEMENT = 1; // NodeFilter.SHOW_ELEMENT; var SHOW_TEXT = 4; // NodeFilter.SHOW_TEXT; -var FILTER_ACCEPT = 1; // NodeFilter.FILTER_ACCEPT; -var FILTER_SKIP = 3; // NodeFilter.FILTER_SKIP; var START_TO_START = 0; // Range.START_TO_START var START_TO_END = 1; // Range.START_TO_END @@ -49,7 +47,6 @@ var hasBuggySplit = ( function () { var notWS = /[^ \t\r\n]/; var indexOf = Array.prototype.indexOf; -/*global FILTER_ACCEPT */ /*jshint strict:false */ /* @@ -103,7 +100,7 @@ TreeWalker.prototype.nextNode = function () { return null; } if ( ( typeToBitArray[ node.nodeType ] & nodeType ) && - filter( node ) === FILTER_ACCEPT ) { + filter( node ) ) { this.currentNode = node; return node; } @@ -133,7 +130,7 @@ TreeWalker.prototype.previousNode = function () { return null; } if ( ( typeToBitArray[ node.nodeType ] & nodeType ) && - filter( node ) === FILTER_ACCEPT ) { + filter( node ) ) { this.currentNode = node; return node; } @@ -144,8 +141,6 @@ TreeWalker.prototype.previousNode = function () { ELEMENT_NODE, TEXT_NODE, SHOW_ELEMENT, - FILTER_ACCEPT, - FILTER_SKIP, win, isOpera, useTextFixer, @@ -214,13 +209,10 @@ function isContainer ( node ) { !isInline( node ) && !isBlock( node ); } -function acceptIfBlock ( el ) { - return isBlock( el ) ?

     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.
