[Javascript] Get the position of the cursor in a textarea?

[Chris Tifer]

Actually, it is:
=========================

<script language="javascript">
<!--

 function emoticon(strEmoticon) {
  var objMailForm = document.forms['form1']
  var objEl = objMailForm.elements['message']
  insertAtCaret(strEmoticon)
  document.form1.message.focus();

 }

//-->
</script>


<SCRIPT language="javascript">
 function storeCaret(){
  var objMailForm = document.forms['form1']
  var objEl = objMailForm.elements['message']
  if (objEl.createTextRange){
   objEl.caretPos = document.selection.createRange().duplicate();
  }
 }


 function insertAtCaret(text){
  var objMailForm = document.forms['form1']
  var objEl = objMailForm.elements['message']
  if (objEl.createTextRange && objEl.caretPos){
   var caretPos = objEl.caretPos;
   caretPos.text =
   caretPos.text.charAt(caretPos.text.length - 1) == ' ' ? text + ' ' :
text;
  }
  else{
   objEl.value += text + " ";
  }
 }
</SCRIPT>
=========================


The insertAtCaret function is the one that seems to find
the position of the insertion point and uses that to place
text. This script is rather cryptic and there's not much documentation,
but I've seen it all around - even on Microsoft's site.

You can also find it on some forums that allow emoticons
as that determines where the emoticon can get entered...
