将浏览器默认的下拉框样式清除,然后应用上自己的,再附一张向右对齐小箭头的图片即可。

 1 select { 2 /*Chrome和Firefox里面的边框是不一样的,所以复写了一下*/ 3   border: solid 1px #000; 4  5 /*很关键:将默认的select选择框样式清除*/ 6   appearance:none; 7   -moz-appearance:none; 8   -webkit-appearance:none; 9 /*在选择框的最右侧中间显示小箭头图片*/10   background: url("http://ourjs.github.io/static/2015/arrow.png") no-repeat scroll right center transparent;11 /*为下拉小箭头留出一点位置,避免被文字覆盖*/12   padding-right: 14px;13 }14 /*清除ie的默认选择框样式清除,隐藏下拉箭头*/15 select::-ms-expand { display: none; }

IE8/9并不支持 appearance:none CSS属性,想要支持的话可能需要非常特殊的方法,参考SF: 我们需要为其添加一个父容器,容器是用来覆盖小箭头的,然后为select添加一个向右的小偏移或者宽度大于父级元素。设置父级的CSS属性为超出部分不可见,即可覆盖即小箭头。然后再为父级容器添加背景图片即可。

1 <div id="parent">2   <select>3       <option>what</option>4       <option>the</option>5       <option>hell</option>6   </select>7 </div>

1 #parent {background: url('yourimage') no-repeat; width: 100px;2 height: 30px; overflow: hidden;}3 #parent select {background: transparent; border: none; padding-left: 10px; width: 120px; height: 100%;}
