• 修改select下拉框的下拉按钮


    ie上的下拉框下拉按钮真是太丑了,如何把他自定义一下呢?

    首先,把浏览器自带的下拉框去掉:  select::-ms-expand { display: none; }

    接下来,用自己喜欢的下拉图片去替换:

            select {
                padding-right:20px;
                color:#a7bce3;
                appearance:none;
                -moz-appearance:none;
                -webkit-appearance:none;
                background: rgba(21, 81, 176, 0.89) url("../../../app/img/select-icon.png") no-repeat scroll right center;
            }

    不过ie上比较奇葩,虽然改后样式看起来统一了,但是点开下拉框后,鼠标滑倒每一个option上,那颜色应该是浏览器自己添加的,我这个背景色,浏览器给配的颜色是这样的:

    所以,这个方法并不能策划地解决下拉框样式的问题,要想彻底解决,就是用、ul li来模拟下拉框。

    展示如下:

    代码如下:

    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="utf-8" />
    <title>案例测试</title>
    <script type="text/javascript" src="jquery.1.7.2.min.js"></script>
    
    <style>
    /* 公共样式 */
    * { padding: 0; margin: 0; list-style: none; font-size: 14px; }
    .hide { display: none; }
    input { outline: none; }
    
    /* 模拟下拉框 */
    .select { position: relative; margin: 50px 0 0 100px; }
    .select .input_in input { width: 188px; height: 20px; line-height: 20px; padding: 10px 0 10px 10px; border: 1px solid #d6d6d6; cursor: pointer; }
    .select .city { position: absolute; top: 40px; left: 0; }
    .select .city ul { width: 198px; border: 1px solid #d6d6d6; border-top: none; }
    .select .city ul li { padding-left: 10px; width: 188px; height: 40px; line-height: 40px; cursor: pointer; }
    </style>
    </head>
    
    <body>
    <!-- End 模拟下拉框 -->
    <div class="select">
        <div class="input_in">
            <input type="text" value="D.C" />
        </div>
        <div class="city hide">
            <ul>
                <li>New York1</li>
                <li>New York2</li>
                <li>New York3</li>
                <li>New York4</li>
                <li>New York5</li>
                <li>New York6</li>
            </ul>
        </div>
    </div>
    <!-- End 模拟下拉框 -->
    
    <script type="text/javascript" >
        $(function(){
    
    //模拟下拉框
        $('.select input').on('click',function(){
            if($('.select .city').is('.hide')){
                $('.select .city').removeClass('hide');
            }else{
                $('.select .city').addClass('hide');
            }
        })
        $('.select ul li').on('click',function(){
            $('.select input').val($(this).html());
            $('.select .city').addClass('hide');
            $('.select input').css('border-bottom','1px solid $d6d6d6');
        })
        $('.select ul li').hover(
            function(){
                $(this).css({'backgroundColor':'#fd9','font-size':'18px'});
            },function(){
                $(this).css({'backgroundColor':'#fff','font-size':'14px'});
            }
        )
        
    })
    </script>
    </body>
    
    </html>

    最好再给下拉按钮做上个下拉图标,那就完美了。
