<form method='post' action='member_login.do' >

   <input name="button" type="submit"
   class="bg03" id="button"  value="確認">

</form>

=============================================

2.

<script>

function ToSubmit(){

frm.action = "member_login.do";

}

<script>

<form method='post' action='' name="frm"  >

   <input name="button" type="submit"
    class="bg03" id="button" onclick="ToSubmit();" value="確認">

</form>

 // PS:

如果有使用action的話 type 就要用submit 否則上敘的frm.action 沒作用

這樣一來就可以用submit方式來透過jquery來審核欄位值才決定是否觸發action

==============================================

3.  直接透過 script處裡,就算在form裡也不會觸發action

<script>
$(function() {
$("#button5").click(function(){
$("#textfield").val('');
$("#textfiemail").val('');
});
});

function showtest(){
alert('ddd');
}

</script>

<form method='post' action='member_login.do' >

   <input name="button5"
    type="button" class="bg03" id="button5" onclick="showtest();" value="取消">

</form>

(  ps:

         type 也可改為reset一樣可以使用jquery 去抓button5 , 也可使用onclick

         而且還可以直接用javascript導頁也不會被檔

)

===========================================================
