Ajax页面刷新错误
Posted
技术标签:
【中文标题】Ajax页面刷新错误【英文标题】：Ajax page refresh error 【发布时间】：2011-07-04 10:54:00 【问题描述】：问题是，在通过 ajax 提交表单时，页面仍然会重新加载，即使已经编写了代码来不刷新页面，而只是刷新某个 div 标签。成功刷新了div标签。
据我所知（我已经检查了五元组），javascript 表单提交和 div 刷新代码一样正确编写。
php 代码中可能存在问题，其中存在通过 ajax 刷新的表单和 div。 php文件和ajax javascript文件在下面...
Php 文件：通过调用 GET ajax=1 刷新 div。该表单称为“addmonitor”，div id 为“monitor_form” - 位于 php 代码底部约 2/3 处：

感谢您的任何见解！
【问题讨论】：
好吧，如果你们都可以亲眼看到操作，您可能会看到问题所在...使用 testingtest33 登录 uptimeology.com/monitor 并打开一些存在的监视器（单击 URL名称），然后通过表单添加新的监视器（URL）。您会看到页面和 iframe 窗口重新加载... 上面的用户名是water-car@hotmail.com 【参考方案1】：不要忘记阻止默认处理程序：
<input type="submit" value="Send" onclick="myAjaxFunction(); return false" />
【讨论】：
这是有道理的。我会做这样的事情。谢谢。 试过了。这是我的代码形式： 和我的代码在 javascript 文件中： $(function myAjaxFunction() $('.button').click(function() // 在此处验证和处理表单...不幸的是，主页仍在重新加载中。【参考方案2】：$(".button") 的href 是否设置为#？如果是这样，那将刷新页面。我建议使用类似的东西：
$(".button").click(function(e)
e.preventDefault();
【讨论】：
这是按钮：codecode
事实上它是一个提交按钮。 :) 就是这样 - 它正在提交表单...您可能希望将事件侦听器添加到表单的提交事件而不是单击按钮 :)
所以基本上不是寻找 $(".button").click 而是实现其他东西。你会推荐什么样的听众？
您是否尝试添加我提到的行？
我做了，但它没有通过函数（e）。它不知道 e 是什么以及 e.preventDefault();然后不起作用。它没有处理表单 - 没有访问下面的行。以上是关于Ajax页面刷新错误的主要内容，如果未能解决你的问题，请参考以下文章
