如何从 标签从语义UI中的标签添加图像

Question

是否可以使用语义UI将图像添加到option标签？像这样的东西：

但是代替div标签，将它们添加到select options：

                <select class="ui dropdown">
                    <option value="1">Apple</option>
                    <option value="2">Pomello</option>
                    <option value="3">Orange</option>
                    <option value="4">Strawberry</option>
                    <option value="5">Plum</option>
                </select>

之所以需要使用select标签是因为我使用了两个动​​态下拉菜单。

一切都很好，除了没有图像或图标。

谢谢你！

您应尝试此操作

//test for getting url value from attr
// var img1 = $('.test').attr("data-thumbnail");
// console.log(img1);

//test for iterating over child elements
var langArray = [];
$('.vodiapicker option').each(function(){
  var img = $(this).attr("data-thumbnail");
  var text = this.innerText;
  var value = $(this).val();
  var item = '<li><img src="'+ img +'" alt="" value="'+value+'"/><span>'+ text +'</span></li>';
  langArray.push(item);
})

$('#a').html(langArray);

//Set the button value to the first el of the array
$('.btn-select').html(langArray[0]);
$('.btn-select').attr('value', 'en');

//change button stuff on click
$('#a li').click(function(){
   var img = $(this).find('img').attr("src");
   var value = $(this).find('img').attr('value');
   var text = this.innerText;
   var item = '<li><img src="'+ img +'" alt="" /><span>'+ text +'</span></li>';
  $('.btn-select').html(item);
  $('.btn-select').attr('value', value);
  $(".b").toggle();
  //console.log(value);
});

$(".btn-select").click(function(){
        $(".b").toggle();
    });

//check local storage for the lang

   var langIndex = langArray.indexOf('ch');
  $('.btn-select').html(langArray[langIndex]);
  //$('.btn-select').attr('value', 'en');
