用js获取select所选的值

<script type="text/javascript">

function change(obj){

var strsel = obj.options[obj.selectedIndex].text;

document.getElementById("xiangmutext").value=strsel;

}

</script>

投票项目 :

<html:select property="xiangmu" onchange="change(this)">

或：<html:select property="xiangmu" onchange="change('xiangmu')">

<html:option value="1" >姚明</html:option>

<html:option value="2">买努</html:option>

<html:option value="3">科比</html:option>

</html:select>

<html:text property="xiangmutext" value="姚明"/>

text中就显示了select所选的内容
