Ajax call with contentType: 'application/json' not working

I have an ajax call, that sends form data to a php function. Since I read a lot that using contentType: 'application/json' is best practice I wanted to give it a try as well. But unfortunately my script doesn't return anything when I use it. If I remove it, the script does what it is supposed to do. Do you have any idea what the reason might be and why? Thank you! $('#Form').su

Ajax调用contentType:'application / json'不起作用

我有一个ajax调用,它发送表单数据到一个php函数。 由于我读了很多使用contentType: 'application/json'是最佳实践,所以我也想尝试一下。 但不幸的是,当我使用它时,我的脚本不会返回任何内容。 如果我删除它,脚本会完成它应该做的事情。 你有什么想法可能是什么原因?为什么? 谢谢! $('#Form').submit(function(e) { e.preventDefault(); var content = $(this).serialize() + "&a

如何为登录和注销的用户构建文件夹?

我希望用户的个人资料显示所有内容(登录导航栏,用于发布其内容的文本框及其所有内容),然后显示他们的个人资料,其中包括注销的导航栏,用户想要显示的选定内容以及没有发布的文本框内容。 我将html文件(例如页眉,页脚和主要内容)分解为单独的php文件。 如果我想实现上述说明,这是一个好主意吗? 我仍在本地主机上开发,但这里是当前的文件结构,有点麻烦。 我也试图实现MVC,但由于我迄今为止缺乏知识,所以还没有
