select控件在火狐浏览器无法调用javascript解决

select 在IE和Firefox的区别 用拉框选择某个值弹出二级菜单火狐下正常在IE下面没反应

解决办法：

<script type="text/javascript">

function changePage() {

var currPage_1 = document.getElementsByName("currpage")[0];

var currPage = currPage_1.options[currPage_1.selectedIndex].value;

window.self.location = "MessageServlet?method=view&currPage="

+ currPage;

}

</script>

<select id="currpage"name="currpage" onchange="changePage()">
