把select下拉框的值传到id中,是网友们比较在意的问题，本人搜索整理下，晒出来和大家分享
完整的代码如下：

想要的效果是：
当我选择ems20运费时，在运送方式中点击下拉框中的运费时那么就用 店铺合计总价+ 20元 当我点击平邮50元时，店铺合计总价+ 50元.
我说的要二个地方显示，是因为他如果存在二个不同的商家的商品时，会有二个商家合起来的总价和 商家商品本身的总价。
解决方法如下：
复制代码代码如下:
<select id="collect" name="postdb[youfei]" onchange="Add(this.value,'total$rs[uid]')">
<option value='10'>快递:10元</option>
<option value='20'>EMS:20元</option>
<option value='50'>平邮:50元</option>
</select>
对name=”postdb[youfei]“属性进行操作，在action中设置名为postdb[youfei]的参数，即：private String postdb[youfei]，然后生成get/set方法，就可以取到值了! |
