检测选择的下拉列表并返回其值和ID

Question

我有几个下拉框。有没有办法检测使用jquery更改了哪个下拉列表？

<form id="products">
 <select id="Ram">
   <option value="0">4 GB</option>
   <option value="1">8 GB</option>
 </select>

 <select id="Hdd">
   <option value="0">300 GB</option>
   <option value="1">500 GB</option>
 </select>
</form>

使用Javascript / Jquery的

$(document).ready(function() {
  $('#products').change(function() {
     var value = $(this).val(); //In here I want to detect and return the value.
     alert(value); // Want to return dropdown ID and its selected value
  });
});

Answer 1

$(document).ready(function() {
  $('select').not('ids of select tags which you want to exclude seperated by a comma').change(function() {
     var id = $(this).attr('id');
     var value = $(this).val();
     alert('ID ='+id+' Value ='+value);
  });
});

Answer 2

阿司匹林是对的，

我会改善他的答案。

$(document).ready(function() {
  $('#products select').change(function() {
     var id = $(this).attr('id');
     var value = $(this).val();
     alert('ID ='+id+' Value ='+value);
  });
});
