Okay as the comments says I missunderstood how ajax works.好的,正如评论所说,我误解了 ajax 的工作原理。
So the answer why it doesnt show anything is - php generates page and script and then the ajax script sends data to php file.所以它没有显示任何内容的答案是 - php 生成页面和脚本,然后 ajax 脚本将数据发送到 php 文件。 To get ajax file data output I need to write JS which gonna put it into html - which is another question how to do that.要获取 ajax 文件数据 output 我需要编写 JS 将其放入 html - 这是另一个问题如何做到这一点。
