Question

我正在制作这个演示。将一些复选框动态添加到诸如引导模态之类的隐藏内容中时，如何获取$(this)甚至检查元素的值？

$('#exampleModal').on('show.bs.modal', function(e) {

  for (var i = 0; i < 3; i++) {
    $('.modal-body').append('<input type="radio" name="addOD" value="item' + i + '" />');
  }
})

$('input:radio[name=addOD]').on('click', function() {
  console.log($(this).val());
  var val = $('input:radio[name=lenseopttype]:checked').val();
  console.log(val);
});

    </div>

如果输入是动态添加的，请将您的点击处理程序更改为类似的内容。

$(function () {
    $(document).on('click', 'input:radio[name=addOD]', function () {
        console.log($(this).val());
        var val = $('input:radio[name=lenseopttype]:checked').val();
        console.log(val);
    });
});
