仅使用CSS进行这种跨浏览器是非常困难的(如果不是不可能的话)。我能想到的唯一给你的元素设置样式的方法就是模拟它。首先,插入一个具有选定值的隐藏文本。这是一个模拟 dropdown-元素的示例 HTML :<select>
input
select
<div class = "select">
<div class = "curVal">Gender</div><div class = "arrow">V</div>
<div class = "choices">
<div class = "choice">Male</div>
<div class = "choice">Female</div>
<div class = "choice">Refuse to answer</div>
</div>
</div>
让我们设计它:
body {
font-family: 'Arial', Helvetica, Sans-Serif;
}
.select div {
display: inline-block;
}
.curVal {
height: 30px;
width: 150px;
line-height: 30px;
vertical-align: middle;
background-color: rgb(0, 162, 232);
color: white;
}
.arrow {
color: white;
background-color: rgb(0, 140, 200); /* this can be an image */
cursor: pointer;
height: 30px;
line-height: 30px;
vertical-align: middle;
position: absolute;
top: 0px;
}
.choices {
position: absolute;
left: 0px;
top: 30px;
background-color: rgb(255, 127, 39);
color: white;
padding: 3px 3px 3px 3px;
width: 150px;
}
.choices div {
display: block;
cursor: pointer;
}
一些jQuery:
$(document).ready()(function(){
$(".choices").hide();
});
$(".arrow").click(function(event) {
$(".choices").slideToggle("fast");
event.stopPropagation();
});
$(".choice").click(function() {
$(".curVal").html($(this).html());
$(".choices").slideToggle("fast");
event.stopPropagation();
});
$("html").click(function() {
$(".choices").slideUp("fast");
});
把它们放在一起,你会得到这个:jsFiddle。
我希望这对你有任何帮助!
