地址栏如何传递参数？下面的有什么错，谢谢

[chcpu]

目的想传递下拉框的值，下面解决方案没有取到值，还是“.../list.asp?selvalue=this[selectedIndex].innerText”，请帮助

<SELECT name="sel" onchange="javascript:location.href='list.asp?selvalue=this[selectedIndex].innerText'">
<OPTION value="aa" selected>aa</OPTION>
<OPTION value="ss">ss</OPTION>
<OPTION value="dd">dd</OPTION>
</SELECT>

<SELECT name="sel" onchange="location.href='list.asp?selvalue='+this.options[this.selectedIndex].value">
<OPTION value="aa" selected>aa</OPTION>
<OPTION value="ss">ss</OPTION>
<OPTION value="dd">dd</OPTION>
</SELECT>
