javascript - Highlight Text in textarea when a Hashtag typed followed by one or more character -

I want the user to be able to type in the text area if he has typed a hash tag or The more letters they write after the highlight is highlighted as long as they do not touch the space.

It's a matter of fact that I want to get something like Facebook's new hash-tag feature, I have argued coding, but still is not enabled

from this perspective I have tried that the use of junkie has been done as follows:

  & lt; Textarea id = "txtArea" & gt; Here's my # hash & lt; / Textarea & gt; $ ("#TxtArea") Onkeyup (function () {var results = $ ("# txtArea"). Match (/ # [\ w] + / g); // result = '# hash'});   
 But I could not finish & amp; I do not know where to go from here, so any solutions, advice, plugins I can use, I would be very grateful.   
 
 
 I believe the word within basic  textarea  (a single There is no way to highlight highlights as it does not accept markup, you are in the  Textera  in a small rich text editor, but it seems that is a bit more complicated, maybe I'm an editor at SO You have to go for a similar approach, and there is a preview window below so that you can see what Asserting that you can use something like this, of course you want to change it to work a little in line with your exact requirements. At least this should give you some ideas.  
 CSS  
  #preview {height: 2em; Width: 12 AM; Border-style: solid; Border width: 1px; }. HashSymbol {color: # f90; }
