JavaScript jQuery调用php无法在iPhone / Ipad上运行

Question

I've been working on the following code today and it works quite nicely on my local machine. 我今天一直在研究以下代码，并且在我的本地计算机上运行良好。 But when I test it on my iPhone/iPad it doesn't work at all. 但是，当我在iPhone / iPad上对其进行测试时，它根本无法工作。

The code is supposed to save the duration of the page visit to a text file when the user leaves the website. 该代码应该在用户离开网站时将页面访问的持续时间保存到文本文件中。 I know there are a lot of alternative scripts for download on the internet, but I want to write this myself. 我知道可以从Internet上下载很多其他脚本，但是我想自己写。 Any suggestions are welcome. 欢迎任何建议。
