在textarea字段中设置焦点和突出显示

I'm displaying a textarea input via PHP using the command :

print " '<textarea rows='16' cols='30'>$flist'</textarea><BR>";

I would like the textarea to have focus and contents $flist be selected automatically. All I've found to date is how to select when the input is clicked.

How would I accomplish this using javascript (no jquery)?

Thanks, Walt

    Write your code as below:-

    // Assign a id to textarea and rewrite below line :-
    print "<textarea rows='16' cols='30'>$flist</textarea><BR>";
    

    In Js use getElementById:-

    <script>
    function setFocusToTextBox(){
       document.getElementById("mytext").focus();
    }
    </script>
