用于textarea和自由文本的Facebook jQuery自动完成插件

Question

Is there a jQuery plugin, similar to Facebook, that suggests/autocompletes with this criteria:

1. Works for a textarea or contenteditable div. I'm finding many plugins that only support input fields (ex. http://loopj.com/jquery-tokeninput/ ).
2. Supports free text, a combination of tags and non-tag text. This is an example that only allows tags after hitting enter: http://brianreavis.github.io/selectize.js/ - This is NOT free text. Examples of free text would be At.js ( http://ichord.github.io/At.js ), jquery-textcomplete ( http://yuku-t.com/jquery-textcomplete ), and jquery.mentionsInput ( http://podio.github.io/jquery-mentions-input )
3. Pill-like CSS effect with backspace/delete functionality. http://yuku-t.com/jquery-textcomplete/ gets pretty close but the styling example doesn't have the delete functionality found in other plugins. Example 1 has a good remove functionality.

Here is an example from Zapier that does it well:

Answer 1

Found rich_textarea, which meets all the criteria.

Answer 2

Even though you've found a plug-in which suits your needs, I figured I'd suggest an alternative (for you, and anybody that may stumble upon this). The more the merrier, right?

Mentionator exceeds* all of your requirements, and is also lighter, and compatible across a greater number of browsers (with it being able to be affixed to <textarea> elements) than rich_textarea (the subject plug-in of the accepted answer at the time of this post).

I should probably mentioned that Mentionator is maintained by yours truly :) .

*Mentionator provides doesRecognizeDelimitedSubstrings and delimValue options, which are described in the Mentionator documentation as:

doesRecognizeDelimitedSubstrings: 
    A boolean which, if defined as true, will allow the external value
    of a mention, herein called "mentionExternalValue", to sustain
    modifications so long as the result of each such modification 
    is in mentionExternalValue.split(delimValue)

delimValue: 
    A string, or regular expression representing the set of strings,
    that, given doesRecognizeDelimitedSubstrings === true, delimit
    mentionExternalValue substrings that can also serve as external
    value of the mention if yielded by a modification of
    mentionExternalValue
