获取checkbox的值放到数组中，然后连接成字符串：

var selectedItems = new Array();
$("input[@name='itemSelect[]']:checked").each(function() {selectedItems.push($(this).val());});

if (selectedItems .length == 0)
    alert("Please select item(s) to delete.");
else
    $.ajax({
    type: "POST",
    url: "/ajax_do_something.php",
    data: "items=" + selectedItems.join('|'),
    dataType: "text",
    success: function (request) {
        document.location.reload();
      },
    error: function(request,error){
        alert('Error deleting item(s), try again later.');
      }
    }
    )
