Question

我试图在下拉列表中插入图片。我尝试了以下代码，但它不起作用。实现这一目标的最佳方法是什么？

 <select>
  <option value="volvo"><IMG src="a.jpg"HEIGHT="15" WIDTH="15" BORDER="0"align="center">Volvo</option>
  <option value="saab"><IMG src="b.jpg"HEIGHT="15" WIDTH="15" BORDER="0"align="center">Saab</option>
  <option value="mercedes"><IMG src="c.jpg"HEIGHT="15" WIDTH="15" BORDER="0"align="center">Mercedes</option>
  <option value="audi"><IMG src="d.jpg"HEIGHT="15" WIDTH="15" BORDER="0"align="center">Audi</option>
  </select>

Answer 1

您无法在纯HTML中执行此操作，但您可以使用jQuery执行此操作：

JavaScript Image Dropdown

你对旧时尚的下拉感到厌烦吗？试试这个新的。图像组合框。您可以为每个选项添加一个图标。它适用于您现有的“select”元素，或者您可以通过JSON对象创建。

Answer 2

此代码仅适用于Firefox：

<select>
    <option value="volvo" style="background-image:url(images/volvo.png);">Volvo</option>
    <option value="saab"  style="background-image:url(images/saab.png);">Saab</option>
    <option value="honda" style="background-image:url(images/honda.png);">Honda</option>
    <option value="audi"  style="background-image:url(images/audi.png);">Audi</option>
</select>

编辑（2018年4月）：

Firefox不再支持此功能了。

这正是您所需要的。请在此处查看8FydL/445

以下示例代码：

CSS：

.desc { color:#6b6b6b;}
.desc a {color:#0092dd;}

.dropdown dd, .dropdown dt, .dropdown ul { margin:0px; padding:0px; }
.dropdown dd { position:relative; }
.dropdown a, .dropdown a:visited { color:#816c5b; text-decoration:none; outline:none;}
.dropdown a:hover { color:#5d4617;}
.dropdown dt a:hover { color:#5d4617; border: 1px solid #d0c9af;}
.dropdown dt a {background:#e4dfcb url('http://www.jankoatwarpspeed.com/wp-content/uploads/examples/reinventing-drop-down/arrow.png') no-repeat scroll right center; display:block; padding-right:20px;
                border:1px solid #d4ca9a; width:150px;}
.dropdown dt a span {cursor:pointer; display:block; padding:5px;}
.dropdown dd ul { background:#e4dfcb none repeat scroll 0 0; border:1px solid #d4ca9a; color:#C5C0B0; display:none;
                  left:0px; padding:5px 0px; position:absolute; top:2px; width:auto; min-width:170px; list-style:none;}
.dropdown span.value { display:none;}
.dropdown dd ul li a { padding:5px; display:block;}
.dropdown dd ul li a:hover { background-color:#d0c9af;}

.dropdown img.flag { border:none; vertical-align:middle; margin-left:10px; }
.flagvisibility { display:none;}

JS：

 $(".dropdown img.flag").addClass("flagvisibility");
    $(".dropdown dt a").click(function() {
        $(".dropdown dd ul").toggle();
    });

    $(".dropdown dd ul li a").click(function() {
        var text = $(this).html();
        $(".dropdown dt a span").html(text);
        $(".dropdown dd ul").hide();
        $("#result").html("Selected value is: " + getSelectedValue("sample"));
    });

    function getSelectedValue(id) {
        return $("#" + id).find("dt a span.value").html();
    }

    $(document).bind('click', function(e) {
        var $clicked = $(e.target);
        if (! $clicked.parents().hasClass("dropdown"))
            $(".dropdown dd ul").hide();
    });

    $(".dropdown img.flag").toggleClass("flagvisibility");

和Demo Html：

 <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>
    <dl id="sample" class="dropdown">
        <dt><a href="#"><span>Please select the country</span></a></dt>
        <dd>
            <ul>
                <li><a href="#">Brazil<img class="flag" src="http://www.jankoatwarpspeed.com/wp-content/uploads/examples/reinventing-drop-down/br.png" alt="" /><span class="value">BR</span></a></li>
                <li><a href="#">France<img class="flag" src="http://www.jankoatwarpspeed.com/wp-content/uploads/examples/reinventing-drop-down/fr.png" alt="" /><span class="value">FR</span></a></li>

            </ul>
        </dd>
    </dl>
    <span id="result"></span>

Answer 5

人，我得到了这个Bootstrap下拉列表。我稍微修改了点击事件，以保留当前选择的图像。如您所见，美元货币是默认选择：

<div class="btn-group" style="margin:10px;">    <!-- CURRENCY, BOOTSTRAP DROPDOWN -->
                <!--<a class="btn btn-primary" href="javascript:void(0);">Currency</a>-->                    
                <a class="btn btn-primary dropdown-toggle" data-toggle="dropdown" href="#"><img src="../../Images/flag-usd-small.png"> USD <span class="caret"></span></a>
                <ul class="dropdown-menu">
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-aud-small.png" /> AUD</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-cad-small.png" /> CAD</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-cny-small.png" /> CNY</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-gbp-small.png" /> GBP</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-usd-small.png" /> USD</a>
                    </li>
                </ul>
            </div>


/* BOOTSTRAP DROPDOWN MENU - Update selected item text and image */
$(".dropdown-menu li a").click(function () {
    var selText = $(this).text();
    var imgSource = $(this).find('img').attr('src');
    var img = '<img src="' + imgSource + '"/>';        
    $(this).parents('.btn-group').find('.dropdown-toggle').html(img + ' ' + selText + ' <span class="caret"></span>');
});

我在这里找到了一个兼容crossbrowser的JQuery插件。

在这种情况下可能很有用。
