  HI mark

  var ta1 = Titanium.UI.createTextArea({
      value:'I am a textarea',
  });
  
  var b1=Ti.UI.createButton({
       title:'Clear'
  });
  b1.addEventListener('click',function(e){
        ta1.value = '';
  });
  

• Hi Mark

  If, in your code, "clear_text_b" is a button control and "comment" is a textArea control, then inside of the button's click event you would simply set the comment's text to equal an empty string, such as "" or ''. By looking at the docs for Titanium.UI.TextArea, I can see that the property used to configure the text that it displays (and that changes when the user types in new content) is "value".

  Hence the line you need is:

  comment.value = '';
  

  Hope this helps. Don't be afraid to ask more questions (although open a separate Q&A question for each of them); we were all there once, and it won't take you long to pick it up.

  Good luck

• Unless you have a particular need for your own button to clear the field, I would suggest letting the system provide the clear button for you. You can specify any of these as a property of the text field when you create it:

  clearButtonMode: Ti.UI.INPUT_BUTTONMODE_ALWAYS;
  clearButtonMode: Ti.UI.INPUT_BUTTONMODE_ONFOCUS;
  clearButtonMode: Ti.UI.INPUT_BUTTONMODE_ONBLUR;
  clearButtonMode: Ti.UI.INPUT_BUTTONMODE_NEVER;
  

  If you don't mention the property at all,it defaults to NEVER and you don't see the system provided clear button. Use any of the other values to have the system provide a clear button for you (a small gray x in a circle) at the time requested by the constant.

  If for some reason you still want your own button, then in the event block where you had "////something here…" just put:

  (name of text field object).value = '';

  If you also want to force the keyboard closed, add:

  (name of text field object).blur();

  Oh wait, I guess you said text area, not text field. I don't think a text area supports a clearButtonMode property – or at least it isn't listed in the Titanium docs – but since I keyed this already I will leave it in my reply in case you (or other readers) are not aware of the clear button option for fields.
