<input value="0001" name="call" id="call"> 

how call value in php script without submit? event onblur or ??

the php file have query :

select * table field = (input  html value) 

you need use ajax that.

<script> $(document).ready(function() { var value = $("#call").val(); $.ajax({ url: "you file path php code written fetch value database", type:"post", data:{"call":value}, success:function(result){alert(result);} })  }); </script>
