[jQuery] Best way to do this for multiple input fields?

[Carlo Landmeter]

Hi,

I'm trying to create a form with multiple input fields. These fields should
have a button to be able to check its content with .ajax.
I am able to create this function for a single field, but i don't know what
the best way would be to do it for multiple input fields:

input#item0
input#item1
input#item2
input#item3
.....

What would be the best way to create this with jquery so i can adjust a
single var to create if for x items?

Thx,

Carlo



$(document).ready(function(){
  $("span#check0").click(function(event){
    $("input#item0").ajaxStart(function(){
      $(this).addClass("loading");
    });
    $("input#item0").ajaxStop(function(){
      $(this).removeClass("loading");
    });
    $.ajax({
      type: "GET",
      url: "checkitem.php",
      data: {
      'sn': $('input#item0').val()},
      'success': function(msg) {
        if (msg == 'OK')
{$("input#item0").removeClass("nowarranty").addClass("warranty");}
        if (msg == 'NG')
{$("input#item0").removeClass("warranty").addClass("nowarranty");}
      },
      'error': function() {alert('Error: please try again');}
    });
  });
});
