JavaScript / DHTML / AJAX Syntax (Toggle Plain Text) 
  1. <script>
  2. function addText(event){
  3. document.getElementById("insertid").value +=
  4. (event.srcElement || event.target).firstChild.nodeValue.toString();
  5. }
  6. </script>
  7. <textarea id="inserid"></textarea>
  8. <table onclick=addText(event)><tr><td>[bbcode][/bbcode]</td><td>[bbcode2][/bbcode2]</td></tr></table>
problem is whe i click on the bbcode or bbcode2 it inserts it at the end of whatever is in the textarea. im looking to insert it into where the user clicks(where the carat is)
like if a user entered in the textearea:
JavaScript / DHTML / AJAX Syntax (Toggle Plain Text)

and the carrot was after hey then when they click the bbcode it enteres it as
JavaScript / DHTML / AJAX Syntax (Toggle Plain Text) 
  1. hey[bbcode][/bbcode] whats up

This is because you are appending the new value always. You have to get the position of the carrot and do some string operation. here is a function to insert in between:-
(http://alexking.org/blog/2003/06/02/...ing-javascript)

javascript Syntax (Toggle Plain Text) 
  1. function insertAtCursor(myField, myValue) {
  2.  
  3.   //IE support
  4.  
  5.   if (document.selection) {
  6.  
  7.     myField.focus();
  8.  
  9.     sel = document.selection.createRange();
  10.  
  11.     sel.text = myValue;
  12.  
  13.   }
  14.  
  15.   //MOZILLA/NETSCAPE support
  16.  
  17.   else if (myField.selectionStart || myField.selectionStart == '0') {
  18.  
  19.     var startPos = myField.selectionStart;
  20.  
  21.     var endPos = myField.selectionEnd;
  22.  
  23.     myField.value = myField.value.substring(0, startPos)
  24.  
  25.                   + myValue
  26.  
  27.                   + myField.value.substring(endPos, myField.value.length);
  28.  
  29.   } else {
  30.  
  31.     myField.value += myValue;
  32.  
  33.   }
  34.  
  35. }
  36.  
  37. // calling the function
  38.  
  39. insertAtCursor(document.formName.fieldName, 'this value');
When you think you have done a lot, then be ready for YOUR downfall.

  1. <script>
  2. function addText(event){
  3. //document.getElementById("insertid").value +=
  4. //(event.srcElement || event.target).firstChild.nodeValue.toString();
  5. insertAtCursor(document.getElementById("insertid"), (event.srcElement || event.target).firstChild.nodeValue.toString())
  6. }
  7. </script>
  8. <textarea id="inserid"></textarea>
  9. <table onclick=addText(event)><tr><td>[bbcode][/bbcode]</td><td>[bbcode2][/bbcode2]</td></tr></table>

I think calling of addText() on click is not correct.

html Syntax (Toggle Plain Text) 
  1. <table id='my_table'><tr><td>[bbcode][/bbcode]</td><td>[bbcode2][/bbcode2]</td></tr></table>

Now on body on load bind the 'onclick' event this way

The body html:
html Syntax (Toggle Plain Text) 
  1. <script>
  2. function init() {
  3.     var table = document.getElementById('my_table');
  4.     if(table) {
  5.         table.onclick = function(e) {
  6.             // Now call your addText function
  7.             addText(e);
  8.         }
  9.     }
  10. }
  11. </script>
  12. <body onload='init();'></body>

Hope you got all that.

Note there are better way to bind events please have a look at 'addEventListener()' javascript function
