通过button将form表单的数据提交到action层的实例

form表单中不需要写action的路径，需要给form表单一个唯一的id，将你要提交的信息的表单中的标签name="action中的javabean对象.javabean属性"。给button按钮添加一个onclick()点击事件，并实现该点击事件，在该onclick()方法中通过ajax将form表单中的数据提交给action层

JSP页面中的代码：

</div>
<pre><code> <div class="modal-footer"&gt;
  <button id="submitButton" onclick="saveButton()" type="button" class="btn btn-primary"&gt;更新</button>
 </div></code></pre>
</form>
   <script type="text/javascript">
    function saveButton(){
      //通过ajax异步将数据发送给action层
      $.ajax({
       url : '${pageContext.request.contextPath}/stu/stu_upstudent.action',//这里写上你的action路径
       data : $("#handleform").serialize(),//将你在form表单上提交的数据序列化
       type : 'POST',//提交方式
       dataType : 'json',//提交的数据类型
       async:true,//是否异步
       success : function(data) {//这是个回调<a href="https://www.jb51.cc/tag/hanshu/" target="_blank" class="keywords">函数</a> data表示从action中传过来的json数据
       //弹出从action层传过来的json格式的数据(用来<a href="https://www.jb51.cc/tag/xianshi/" target="_blank" class="keywords">显示</a>是否更新成功)
       alert(data.result);
       }
      });
    }
   </script></pre>
</div>
