This function is implemented, but feel a bit uncomfortable, you must use the HTML editor, but from the full selection of HTML editor in the code, notice the createTextRange () method, this method has been useful before, but has not been thoroughly studied. Found in MSDN that only objects such as body, textarea, and so on support the createTextRange () method, continue to be looked up in MSDN, createTextRange () returns a TextRange object, continues to consult TextRange object, found that there are many methods, first tried FindText method, found only text, can not select the object, continue to find, finally found Movetoelementtext is the way we are looking for:

<input type= "button" value= "Selected Test form" onclick= "copytable ()" > Test <table border= "1" id= "otable" > <TR> & Lt td> Test form </TD> <TD> Test form </TD> </TR> <TR> <TD> Test form </TD> <TD> Test form ;/td> </TR> </TABLE> text <script language= "JavaScript" > <!--function copytable () {var txt = Document.body.createTextRange (); Txt.movetoelementtext (otable); Txt.select (); }--> </SCRIPT>
