_div

The offscreen div to paste the data to.

_editor

A reference to the editor object.

_finishing

Flag to indicate that we're currently are busy with finishing a paste action.

_intercepting

Flag to indicate that we're currently are busy with intercepting a paste action and that there is data ready to be inserted.

_pasteMethod

The paste method to use: 'text', 'filtered' or 'html'

_saveRange

The stored range (or bookmark in IE) to be able to restore the cursor position after the editor focus was moved to the offscreen div.

_scrollTop1

One of the scroll tops to save (and restore) if the document scroll offset changes when the helper div is created and removed.

_scrollTop2

One of the scroll tops to save (and restore) if the document scroll offset changes when the helper div is created and removed.

_tagFilter

Set of allowed tags an allowed attributes for tag filtering.

_createPasteDiv()

Create an offscreen div as target for the paste actions so that we can access and process the data.

_filter()

Filter all unwanted tags and attributes from an HTML text string.

_filterClass(nd, cls)

When filtering (actually transfering) CSS class names keep the scrivo system styles.

_filterTags(src, dest)

Copy an HTML DOM sub tree from a HTML element to an other empty element node. And while doing so forget all unwanted tags and attributes, thus in effect filter the tree.

_finishPaste()

Finish a pending pasting action: filter out unwanted tags from the pasted data, remove the helper div and insert the cleaned data in the correct location of the document in the editor.

_finishPasteIE()

Finish a pending pasting action: filter out unwanted tags from the pasted data, remove the helper div and insert the cleaned data in the correct location of the document in the editor. This method is of course specific to IE.

_interceptPaste()

In order to manipulate the paste buffer we need to intercept the paste action. Therefore we create an offscreen contenteditable div that gets the focus over the editor's contenteditable. On a later moment we use 'finishPaste' to manipulate the pasted data and insert it into the editor.

_interceptPasteIE()

In order to manipulate the paste buffer we need to intercept the paste action. Therefore we create an offscreen contenteditable div that gets the focus over the editor's contenteditable. On a later moment we use 'finishPaste' to manipulate the pasted data and insert it into the editor. This method is of course specific to IE.

_toText(src, dest, prev)

Convert HTML that was filtered using the _filterTags method to plain text.

finishPaste()

The listener method to use on the 'keyup' event handler of the HTML editor to finish an intercepted the paste actions. If it is detected that there is data to be pasted the data will we cleaned using the currently set paste method and inserted into the content.

interceptPaste()

The listener method to use on the 'onbeforepaste' (IE) and 'onpaste' (others) event handlers to intercept the paste actions. If the paste method was set to 'html' the method returns true so that pasting will continue as default. In the case of 'text' or 'filtered' the data will be pasted to an offscreen div to process it by finishPaste later.

pasteMethod(p)

Get or set the paste method to use when pasting.
