Answer 1

$('input[name*="name"]').spinner({ 
    min: 0, 
    max: 100, 
    spin: function(event, ui) { 
     $(this).change(); 
    } 
});

嘗試以下操作：

$(function() { 
    var spinner = $("#spinner").spinner({ 
     step: 2 , 
     spin: function(event, ui){ 
      handleSpinnerValue(ui.value); 
     } 
    }); 
}); 
function handleSpinnerValue(txtValue) 
{ 
    //do here whatever you want with the value; 
    alert(txtValue); 
}
