$().ready(function(){
    
   //Default Enter for search
   document.addEvenListener('keydown',function(event){
   if (event.keyCode === 13 ){
     $('search').click();
     }  
    });
  });

查詢鍵盤 keyCode :

<!DOCTYPE>
<html>
<body>

<input type="text" size="40" onkeypress="searchFunction(event)">
<p id="demo"></p>
<script>
function searchFunction(event){

    var x = event.keyCode;    
    //Key codes -> A number which represents an actual key on the keyboard
   
    var y =String.fromCharCode(x); 
    //The fromCharCode() method converts Unicode values into characters.
    //Character codes -> A number which represents an ASCII character

    document.getElementById('demo').innerHTML = "Number : " + x + " = Character: " + y ;    
}

</script>
</body>
</html>
