I have a text area with comma delimited string.
Let's say it's: "New York, Paris , London," i would like to click on one of the word and get it removed from the text area.
So if i click on Paris, then it's going to be only " New York , London".
Is it possible to accomplish it in any way?

Thank you

{
  if (what.selectionStart!=what.selectionEnd) return
  var str=what.value
  var pos=what.selectionStart
  var from=str.lastIndexOf(',',pos)
  var to=str.indexOf(',',pos)
  if (from==-1) { from=0; if (to!=-1) to++ }
  if (to==-1) to=str.length
  what.value=str.substr(0,from)+str.substr(to)
}

Thanks, but it doesn't look like it works.
The var pos=what.selectionStart returns "underfined".
Please take a look and thanks again.
