var rangeObj = document.createRange ();
rangeObj.selectNodeContents (srcObj);
rangeObj.deleteContents ();
}
else { // Internet Explorer before version 9
var rangeObj = document.body.createTextRange ();
rangeObj.moveToElementText (srcObj);
rangeObj.select ();
rangeObj.execCommand ("cut");
}
}
</script>

<script type="text/javascript">
function TestSelection () {
if (window.getSelection) { // all browsers, except IE before version 9

}
else {
if (document.selection.type == "None") {
alert ("No content is selected, or the selected content is not available!");
}
else {
var textRange = document.selection.createRange ();
alert ("The text content of the selection:n" + textRange.text);
}
