jQuery mobile 表单提交http://blog.csdn.net/tjpu_lin/article/details/28394253最近在做手机页面用jQuery mobile开发，在用到form表单提交到时遇到了问题。后台是用servlet进行处理的，想通过Servlet里面的重定向进行页面跳转发现在手机上根本没有用，出现errorpage提示信息。查询网上资料以及jQuery mobile API得知 jQuery mobile表单提交默认是ajax提交，所以页面跳转写在servlet里面根本就不会实现页面跳转功能。于是我按照教程在form里面加了 data-ajax=“false”这一属性，发现别说是页面跳转不行，就连后台的数据库操作都做不了，报了500错误。想了好久既然用ajax提交，那么就用ajax进行页面跳转
[html] view plaincopy在CODE上查看代码片派生到我的代码片<script type="text/javascript"> $(document).ready(function () { $("#submitbtn").click(function(){ cache: false, $.ajax({ type: "POST", url: "feedback", data: $('#feedbackform').serialize(), success:function(data){ $.mobile.changePage("success.html"); } }); }); }); </script> [html] view plaincopy在CODE上查看代码片派生到我的代码片<form method="post" id="feedbackform"> t;span style="white-space:pre"> </span>//相关表单元素 <input type="button" id="submitbtn" value="提交"> </form> 注意的是js里面的data
[html] view plaincopy在CODE上查看代码片派生到我的代码片$('#feedbackform').serialize() 是必须要有的，不然servlet里面用requset.getParameter接受的数据是null，ajax和后台成功交互后用changePage跳转到成功后显示的页面。</pre><pre code_snippet_id="1849295" snippet_file_name="blog_20160824_1_2775332" name="code" class="html"><dt style="list-style: none; word-break: break-all; word-wrap: break-word; margin: 0px; padding: 4px 0px 0px 7px; float: left; width: 77px; height: 60px; font-family: Verdana, 'Lucida Grande', Arial, Helvetica, sans-serif;"><a target=_blank href="http://my.csdn.net/" style="list-style: none; text-decoration: none; word-break: break-all; word-wrap: break-word; color: rgb(59, 89, 152); margin: 0px; padding: 0px;"><img src="http://avatar.csdn.net/2/A/1/3_u011447828.jpg" alt="u011447828" style="list-style: none; word-break: break-all; word-wrap: break-word; border: none; margin: 0px; padding: 0px; width: 48px; height: 48px;" /></a></dt><dd style="list-style: none; word-break: break-all; word-wrap: break-word; margin: 0px 0px 0px -10px; padding: 4px 0px 0px; float: left; width: 500px; font-family: Verdana, 'Lucida Grande', Arial, Helvetica, sans-serif;"><ul style="list-style: none; word-break: break-all; word-wrap: break-word; margin: 0px; padding: 0px;"><li class="user_name" style="list-style: none; word-break: break-all; word-wrap: break-word; margin: 0px; padding: 0px; font-stretch: normal; font-size: 14px; line-height: 24px; font-family: Arial, Helvetica, sans-serif;"><a target=_blank href="http://my.csdn.net/" class="user_name" style="list-style: none; text-decoration: none; word-break: break-all; word-wrap: break-word; color: rgb(68, 68, 68); margin: 0px 1em 0px 0px; padding: 0px; font-weight: bold; font-stretch: normal;">afterrains</a><span style="list-style: none; word-break: break-all; word-wrap: break-word; margin: 0px; padding: 0px; color: rgb(58, 156, 211);">别在熬夜了！</span></li><li class="feed_link" style="list-style: none; word-break: break-all; word-wrap: break-word; margin: 0px 0px 0px -5px; padding: 0px; color: rgb(170, 170, 170); font-stretch: normal; line-height: 24px; font-family: Arial, Helvetica, sans-serif;"><a target=_blank href="http://my.csdn.net/" style="list-style: none; text-decoration: none; word-break: break-all; word-wrap: break-word; color: rgb(7, 81, 154); margin: 0px 6px; padding: 0px;">个人主页</a>|<a target=_blank href="http://blog.csdn.net/u011447828" style="list-style: none; text-decoration: none; word-break: break-all; word-wrap: break-word; color: rgb(7, 81, 154); margin: 0px 6px; padding: 0px;">我的博客</a></li></ul></dd>
