html button

HTML code

<form action="" method="post">     <input type="button" onclick="metho()"></form>

metho()方法实现提交表单,并使页面跳至servlet,能实现吗

[解决办法]
给form加个id，用form提交，是这个意思么？

HTML code

<script type="text/javascript">function metho() {        var dForm = document.getElementById("dForm");        dForm.action = "process.do";        dForm.submit();    }</script><form action="" method="post" id="dForm>     <input type="button" onclick="metho()"></form>

HTML code
<script type="text/javascript">function metho() {        var dForm = documentforms[0];        dForm.action = "url";        dForm.submit();    }</script><form action="" method="post">     <input type="button" onclick="metho()"></form>
[解决办法]
<script type="text/javascript">
function metho() {
       var dForm = document.getElementById("dForm");
       dForm.action = "process.do";
       dForm.submit();
   }
</script>

<form action="" method="post" id="dForm>
    <input type="button" onclick="metho()">
</form>



-->等价于

<form action="process.do" method="post" id="dForm>
    <input type="submit"   />
</form>

上面的绕道到js里面提交到process.do
