html - show * when field not valid -


i @ level 0 in breeze bear me. dont want ready made code of now. using breeze , want client side validation. want show "*" near html input if data entered not valid. below code bind data returned breeze.

               <td > <input data-bind="value: name" /></td>

how can achieve using breeze? please let me know if there live example can refer to. tried googling couldnt find examples.

not breeze, pure js might help?

<!doctype html>  <html>     <head>         <title>untitled</title>         <style type='text/css'>             span.red { color:red; }         </style>         <script>             function validatefields() {                 //usually use regex check phones, example.                 // test if value '123456' in example.                 if ('123456' == document.getelementbyid('inpphone').value) {                     document.getelementbyid('spnphonevalid').innerhtml = '';                 } else {                     document.getelementbyid('spnphonevalid').innerhtml = '*';                 }             }          </script>     </head>      <body>         phone number (only 123456):<input id='inpphone' onchange='validatefields();'> <span class='red' id='spnphonevalid'>*</span>     </body> </html>

and of course it's client's usability , not instead of server-side validation!
