请帮我。

UPD： - IE8 与 Chrome 中的结果相同

Answer 1

一些浏览器使用本机控件实现下拉菜单，并且不允许设置样式。除了用其他元素的集合和一堆 JavaScript 替换元素之外，您对此无能为力。

Answer 2

也许试试

-webkit-appearance:none;

和

-webkit-box-sizing: contents-box;

Answer 3

我用列表来做

JS：

(function ($) {
    $.fn.postcodeAddressList = function() {

        this.each(function() {
            var el = $(this),
            li = el.find('li'),
            i = li.length;

            strippedList(el);

            while(i--) {
                $(li[i]).on("click", function(e){ 
                    strippedList(el);
                    $(e.currentTarget).attr("selected", "selected");
                    el.attr("data",$(e.currentTarget).attr("data"));
                });
            } 
        });

        return this;
    };
})(jQuery);

strippedList =  function ( el) {
    var li = el.find('li'),
        i = li.length; 

     while(i--) {
         if($( li[i] ).attr("selected")!= 'defined') {
             $(li[i]).removeAttr("selected");
         }
         if (i%2) {
             $(li[i]).attr("stripped","stripped");
         }else {
             $(li[i]).removeAttr("stripped");
         }
     }

}

CSS：

.postCode li[stripped="stripped"] {
    background-color: #f5f5f5;
}
.postCode li[selected="selected"] {
    background-color: #ccc;
}
.postCode li
{
    background-image: url('../img/house.png');
    background-repeat: no-repeat;
    background-position: 5% 50%;
    padding: 7px 0 7px 4em;
    cursor: pointer;
    font-weight: bold;
    color: #333;
}
.postCode[disabled="disabled"] {
    background-color: #f5f5f5;
    border-color: #ddd;
    cursor: not-allowed;
}
.postCode {
    background-color: white;
    list-style: none outside none;
    margin-left: -10px;
    padding: 5px 0;
    width: 340px;
    height: 300px;
    overflow-y: auto;
    border: solid 1px #CCC;
    border-radius: 5px;
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
}

HTML：

<ul class="postCode" data="29392449_0S_F">
    <li data="26850525_898354S_F">Andrew Begg 24-26 Upperkirkgate Aberdeen</li>
    <li data="31763873_0S_F" stripped="stripped">Flat 1 12 Upperkirkgate Aberdeen</li>
    <li data="31763875_0S_F">Flat 1 14 Upperkirkgate Aberdeen</li>
    ...
</ul>

利用：

...
$('.postCode').postcodeAddressList();
...


...
var value = $('.postCode').attr("data");
...

结果：
