<select name="proddllist1" id="proddllist1" onchange="getproductprice('proddllist1','proprice1')">
<option value="请选择商品">请选择商品</option>
<option value="纸巾">纸巾(———拥有的种类如下———)</option>
<option value="清萱318张压花方巾纸">清萱318张压花方巾纸(1*8*5)</option>
<option value="清萱120抽盒装面巾纸">清萱120抽盒装面巾纸(1*16*3)</option>
<option value="C1410+1610心相印手帕纸“几米”">C1410+1610心相印手帕纸option>
<option value="400张紫金花纯木浆压花面巾纸">400张紫金花纯木(1*30)</option>
<option value="牙刷">牙刷(———拥有的种类如下———)</option>
</select>
如何用javascript脚本语言之类的把里面的所有<option></option>节点数据全部复制到另外个<select></select>下拉框中呢?
