New delimiter for textarea in html

Question

I am trying to give the user the opportunity to create a custom list for my application by inserting his selection in the text area field, each line is considered as one of the options, using \ n (enter) as a separator, I need to allow the user to enter one choice in several lines, any may I help?

<textarea></textarea>

enter the user: aa bb cc with enter in textarea, and then I process them to split them into an input separator, so I have three options in the list: 1-aa, 2-bb and 3-cc, but I need do aa, bb first option and second variant cc, i need a new delimiter, i need more ideas?

<script type="text/javascript">
  var LastKeyCode=-1;

  function updateOptions(e) {

      var KeyCode=e.keyCode;
    } else {
      var KeyCode=e.charCode;
    }

    if (KeyCode==13 && LastKeyCode==13) { // Enter?
      var RowsDataAry=document.getElementById('inputfield').value.replace(/\r\n/g,"\n").split(/\n{2,}/g);  // Fix IE CRs and split the textarea input

      document.getElementById('choices').options.length=0;  // Empty select

      for (RowID in RowsDataAry) {
        var TextVal=RowsDataAry[RowID].replace(/\n/g,", ").replace(/, $/,"");   // Set commas and remove the last comma

        document.getElementById('choices').options.length++;
        document.getElementById('choices').options[RowID].value=RowID;  // Add option value
        document.getElementById('choices').options[RowID].text=TextVal;
;  // Add option text
      }
    }

    LastKeyCode=KeyCode;
  }
</script>
