今天遇到一个很是纠结的问题,需求又改了!原生的select给option加样式,结果发现select选中仍是默认样式,如下图:

左思右想之后,感觉模拟一个实在太麻烦了(原来页面结构得变动、样式也得重写甚至要多写好多js和css代码,总之感觉因为这么个小需求去做大改动不(ai)值(tou)得(lan))!
...经过一番思想上的斗争与逻辑的整理,效果实现了:

直接上代码:
html:
<select name="" id="bankSelect" onChange="changSel()">
<option>中国银行</option>
<option color="yelllow" style="color:#F00">农业银行(正在升级中)</option>
<option>建设银行</option>
</select
js:
<script type="text/javascript">
function changSel(){
$('#bankSelect option[color!="yelllow"]').css('color','#000'); //option没有自定义属性color="yelllow"默认为黑色
if($("#bankSelect option:selected").text().indexOf("(")>=0 && $("#bankSelect option:selected").text().indexOf(")")>=0) //如果选中option中包含"("和")"给select加红色
{
$('#bankSelect').css('color','red');
}
else{
$('#bankSelect').css('color','#000'); //否则为默认的黑色
}
}
</script>
逻辑就是这样的了 最好是直接判断是否有color这个自定义属性
