Question

<select id="MyId" name="Myname">
  <option value=1>Tom</option>
  <option value=12>Harold</option>e 
  <option value=32>Jenny</option>
</select>

使用

$('select option:selected').each(function () {
    var $el = $(this);
    var text = $el.attr('text');
    alert(text);
 });

我可以获得选项文字

但是如何获取选择标签名称或ID以及所选的选项文本？如下所示返回undefined:text

    $('select option:selected').each(function () {
    var $el = $(this);
    var text = $el.attr('text');
    var name = $el.attr('name');
    alert(name + ":" + text);
    });

Answer 1

使用.change()

$('select').change(function() {
   var name = $(this).attr('name'); // get select tag name
   var id = $(this).attr('id'); // get select tag id
   var selectedOption = $(this).val(); // get selected option
   var selectedText = $(this).find('option:selected').text(); // get selected option text
});

Answer 2

使用closest()或parent()获取其ID和名称必需的选择。

$('select option:selected').each(function () {    
    var select = $(this).parent('select');//the tag object
    alert($(this).closest('select').attr('id'));//id
    alert($(this).parent('select').attr('name'));//name
});

Answer 3

Try This

$('select option:selected').each(function () {
  var $el = $(this);
  var text = $el.text();
  alert(text);
});

                    var mySelect = $(this);
                    alert("selected " + mySelect.find('option:selected').text());
                });
            });
