javascript - ASP textbox from right-left / left-right -

how can write right left after pressing alt+shift

and writing left right pressing alt+shift inside asp textbox

(different languages)

any ideas ??!

in .aspx markup add following

<script type="text/javascript">   function handlekeydown(e) {     var altpressed = 0;     var shiftpressed = 0;     var evt = (e == null ? event : e);      altpressed = evt.altkey;     shiftpressed = evt.shiftkey;      if (altpressed && shiftpressed) {         var textdemo = document.getelementbyid('textboxdemo');         textdemo.classlist.toggle("otherdir");     }      return true; } </script>  <style>   .otherdir {direction:rtl} </style>  <asp:textbox id="textboxdemo"  cssclass="otherdir" runat="server" clientidmode="static" /> 

in page load event, add following line:

textboxdemo.attributes.add("onkeydown", "handlekeydown()"); 

the above line add client-side event handler pressing alt-shift in html input rendered. toggle direction each time keyboard combo pressed.
