jquery - Required field that should be filled only with integers -


i working upon validation of field in field should filled integers , validation field needed given?

i inserted script tags follows:

<script type="text/javascript" src="jquery.numeric.js"></script> <script> jquery(document).ready(function(){ $("#estvalue").numeric({ negative: false  },  function() { alert("no negative values"); this.value = ""; this.focus(); }); });   </script> <input name="est_value" id="estvalue" class="regi_input_1" style="width: 150px; height: 25px;" type="text" />

use html5

<input type="number" min="0" />   <input name="est_value" id="estvalue" class="regi_input_1" style="width: 150px; height: 25px;" type="number" min="0" />
