我在页面底部有Ajax。我确定为什么它不能在iPhone Safari上触发。也许正在执行，但是有一些错误。
注意 ：
- 在Mac OS X的Chrome或Safari上使用相同的代码。
- Ajax确实触发了，并且工作正常。？
Ajax似乎不会在iPhone Safari上触发
我是否使用iPhone上的Safari无法识别的旧语法？
人们将如何进行进一步调试？
您可以使用Safari WebInspector
你需要一个Mac与Xcode安装。
您需要在ip上本地运行服务器。打开您的终端并运行ifconfig，找到您的IP，然后enp1s0为ethernet或wlp2s0进行复制。
~ $ ifconfig
enp1s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.38 netmask 255.255.255.0 broadcast 192.168.1.255
wlp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.6 netmask 255.255.255.0 broadcast 192.168.1.255
在此ip上通过网站运行服务器。随着我运行轨道rails server -b 192.168.1.38 -p 3000，-b代表ip binding和-p端口。
打开Xcode并启动新的模拟器或通过USB连接设备。
请按照以下说明http://192.168.1.38:3000在iPhone仿真器上打开。
如果您在配置iPhone进行调试时遇到困难，请记住以下说明中的重要步骤：
- 仅在使用USB DEVICE 时才
Webinspector需要启用该选项。您无需在模拟器设备上标记此选项。我在模拟器上没有它，并且能够运行webinspector。 - 运行模拟器并使用移动浏览器浏览器打开页面后，您需要打开桌面浏览器浏览器并
Develop通过选中在菜单栏中启用Show develop menu in menu bar。
如果在菜单栏中看不到“开发”，请转到菜单栏，然后单击“ Safari>首选项>高级”，然后选中“在菜单栏中显示开发菜单”复选框。
- 从菜单栏中选择野生动物园
Develop -> Simulator or Iphone -> Your Page
在开发人员工具栏中，打开Timelines/Network Request或Network如指南中所示，检查您的网络请求
检查您的服务器日志以查看后端是否正在接收AJAX请求，或者检查phone simulator日志，因为您可能会看到一些与证书或其他原因有关的错误。您必须在线研究这些错误的解决方案。
当我使用构建项目时xcode，我还能够从xcode中的电话中看到控制台日志
