Python 带有web.py的表单按钮例程
我有一个有3个按钮的页面。当我按下一个按钮时，我希望页面告诉我按下了哪个按钮。最后，我想从这个页面切换流程和运行脚本，并立即在按钮旁边获得反馈。就像一个控制面板 我的问题是执行按钮操作，对其执行一些操作，然后使用按钮将结果返回到页面 我已经阅读了web.py表单教程并进行了跟踪。我还查找了templetor中的示例，其中的所有表单似乎都处理登录例程或将响应写入数据库。有时，响应会显示在新页面上，但不会显示在按钮旁边的同一页面上 在我构建表单例程的过程中，一定有一些我不了解的东西 脚本：Python 带有web.py的表单按钮例程,python,python-2.7,web.py,Python,Python 2.7,Web.py,我有一个有3个按钮的页面。当我按下一个按钮时，我希望页面告诉我按下了哪个按钮。最后，我想从这个页面切换流程和运行脚本，并立即在按钮旁边获得反馈。就像一个控制面板 我的问题是执行按钮操作，对其执行一些操作，然后使用按钮将结果返回到页面 我已经阅读了web.py表单教程并进行了跟踪。我还查找了templetor中的示例，其中的所有表单似乎都处理登录例程或将响应写入数据库。有时，响应会显示在新页面上，但不会显示在按钮旁边的同一页面上 在我构建表单例程的过程中，一定有一些我不了解的东西 脚本： #===

$def带（表单、按钮）
您一定在谈论异步请求，在异步请求中，网页可以处理请求而不刷新页面。不像web.py示例那样是登录页面
简单。对作业使用jQuery。这已经足够让你开始了。但在这里我会给你举个例子
将此代码段添加到.js文件：
$.ajax({
url: '/',
type: 'POST',
data: {
params: text
}).done(function(){
/* Do something */
});
