But this will not work in firefox
because document.selection.createRange() is undefined
You need something like

Code:

 if (window.getSelection)
{
txt = window.getSelection();
foundIn = 'window.getSelection()';
}
else if (document.getSelection)
{
txt = document.getSelection();
foundIn = 'document.getSelection()';
}
else if (document.selection)
{
txt = document.selection.createRange().text;
foundIn = 'document.selection.createRange()';
}
else return;

Too bad later i found that window.getSelection will not work in textarea.. and yet this is bug for firefox according
http://www.squarefree.com

Code:

 function copyit(theField) {

var selectedText = document.selection;

var txt;
var foundIn;

if (window.getSelection)
{
txt=getSelectionInfo(theField);
//alert('ori='+theField.value.length);
   //alert('new='+txt.length);
if(txt.length==theField.value.length )
theField.value='';
}
else if (document.getSelection)
{
alert('2='+document.getSelection);
txt = document.getSelection();
foundIn = 'document.getSelection()';
theField.focus();
theField.value = txt;
}
else if (document.selection)
{
alert('3='+document.selection);
if (document.selection.type == 'Text') {

 txt = document.selection.createRange().text;
 alert('ori='+theField.value.length);
 alert('3='+txt.length);
 if(theField.value.length==txt.length)
 alert('clearAll!!');
 foundIn = 'document.selection.createRange()';
 theField.focus();
 theField.value = txt;
}
}
else return;

;

}
function getSelectionInfo(theField)
{
var rv = "";
var i,x;

x = theField;

 rv +=  x.value.substr(x.selectionStart, x.selectionEnd - x.selectionStart);

if(x.selectionStart==0 && x.selectionEnd==x.value.length)
return rv;
}
