Question

有没有办法在选项标签上支持悬停？我想更改选项标签的高亮颜色。

<select>
    <option value="a">a</option>
    <option value="b">b</option>
    <option value="c">c</option>
    <option value="d">d</option>
</select>

我不想使用ul li。谁能帮我吗？感谢

您实际上无法设置选项标签的样式，但这里有一个很酷的解决方法，您仍然可以使用您的选择和选项元素：https://codepen.io/wallaceerick/pen/ctsCz

（JavaScript）的

$('select').each(function(){
    var $this = $(this), numberOfOptions = $(this).children('option').length;

    $this.addClass('select-hidden'); 
    $this.wrap('<div class="select"></div>');
    $this.after('<div class="select-styled"></div>');

    var $styledSelect = $this.next('div.select-styled');
    $styledSelect.text($this.children('option').eq(0).text());

    var $list = $('<ul />', {
        'class': 'select-options'
    }).insertAfter($styledSelect);

    for (var i = 0; i < numberOfOptions; i++) {
        $('<li />', {
            text: $this.children('option').eq(i).text(),
            rel: $this.children('option').eq(i).val()
        }).appendTo($list);
    }

    var $listItems = $list.children('li');

    $styledSelect.click(function(e) {
        e.stopPropagation();
        $('div.select-styled.active').not(this).each(function(){
            $(this).removeClass('active').next('ul.select-options').hide();
        });
        $(this).toggleClass('active').next('ul.select-options').toggle();
    });

    $listItems.click(function(e) {
        e.stopPropagation();
        $styledSelect.text($(this).text()).removeClass('active');
        $this.val($(this).attr('rel'));
        $list.hide();
        //console.log($this.val());
    });

    $(document).click(function() {
        $styledSelect.removeClass('active');
        $list.hide();
    });

});

.select-options li:hover {
