the text highlighted is saved and shown in a popup in this example, but we can use it in any applications. (this is similar to T-SQL query execution process, in which we can execute only the highlighted portion).

<script language=javascript>
function getSelText()
{

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

//var mytxt = txt;
//document.getElementById("selectedtext").value = txt;

alert(txt);
alert(document.getElementById("selectedtext").value);

}
</script>

<html>
<form name=aform action="" >
<textarea name="selectedtext" rows="5" cols="20" ></textarea><br />
<input type="button" value="Get selection" onClick="getSelText()">
</form>
</html>
