man ir shaads kods (kods iespeejams ir videeji garsh, bet nav sarezgjiits - vairaakas daljas atkaartojas) :

<script type="text/javascript">
function getSelection(ta)
 { var bits = [ta.value,'','','']; 
if(document.selection)
  { var vs = '#$%^%$#';
	var tr=document.selection.createRange()
	if(tr.parentElement()!=ta) return null;
	bits[2] = tr.text;
	tr.text = vs;
	fb = ta.value.split(vs);
	tr.moveStart('character',-vs.length);
	tr.text = bits[2];
	bits[1] = fb[0];
	bits[3] = fb[1];
  } 
else
  { if(ta.selectionStart == ta.selectionEnd) return null;
	bits=(new RegExp('([\x00-\xff]{'+ta.selectionStart+'})([\x00-\xff]{'+(ta.selectionEnd - ta.selectionStart)+'})([\x00-\xff]*)')).exec(ta.value);
  }
 return bits;
 }

function matchPTags(str)
 { str = ' ' + str + ' ';
ot = str.split(/\[[B|U|I].*?\]/i);
ct = str.split(/\[\/[B|U|I].*?\]/i);
return ot.length==ct.length;
 }

function addPTag(ta,pTag)
 { bits = getSelection(ta);
if(bits)
  { if(!matchPTags(bits[2]))
	  { alert('\t\tNav aizvērta kāda iekava.');
		return;
	  }
	ta.value = bits[1] + '<' + pTag + '>' + bits[2] + '</' + pTag + '>' + bits[3];
  }
 }

function addZTag(ta,pTag)
 { bits = getSelection(ta);
if(bits)
  { if(!matchPTags(bits[2]))
	  { alert('\t\tNav aizvērta kāda iekava.');
		return;
	  }
	ta.value = bits[1] + bits[2] + '</' + pTag + '>' + bits[3];
  }
 }

function addATag(ta,pTag)
 { bits = getSelection(ta);
if(bits)
  { if(!matchPTags(bits[2]))
	  { alert('\t\tNav aizvērta kāda iekava.');
		return;
	  }
	ta.value = bits[1] + '<' + pTag + ' HREF="uploads/___FAILA NOSAUKUMS___"' + '>' + bits[2] + '</' + pTag + '>' + bits[3];
  }
 }

</script>
</head>
<body>

<button onClick="addPTag(document.getElementById('text'),'B')"><b>Bold</b></button>
<button onClick="addPTag(document.getElementById('text'),'I')"><i>Italic</i></button>
<button onClick="addPTag(document.getElementById('text'),'U')"><u>Underline</u></button>
<button onClick="addZTag(document.getElementById('text'),'BR')">Rindkopa</button>
<button onClick="addATag(document.getElementById('text'),'A')">Links</button>

bits=(new RegExp('([\x00-\xff]{'+ta.selectionStart+'})([\x00-\xff]{'+(ta.selectionEnd - ta.selectionStart)+'})([\x00-\xff]*)')).exec(ta.value);
