我在页面底部有Ajax。我确定为什么它不会在iPhone Safari上触发。或者它正在执行,但有一些错误。

注意 :

  • Mac OS X上Chrome或Safari上的相同代码.✅
  • Ajax确实触发了,并且工作正常。 ✅

Ajax似乎没有在iPhone Safari上触发

我使用iPhone上的Safari无法识别的任何旧语法吗?

如何进行并进一步调试?

您可以使用Safari Web Inspector

你需要一个与MacXcode installed

您需要在ip上本地运行服务器。打开你的终端并运行ifconfig,找到你的IP并复制enp1s0ethernetwlp2s0为wifi。

~ $ 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

在这个ip上用你的网站运行你的服务器。有轨道我运行rails server -b 192.168.1.38 -p 3000-b代表ip binding-p代表港口。

打开Xcode和start a new emulator或通过USB连接您的设备。

按照this instructions在你的iphone模拟器上打开http://192.168.1.38:3000

如果您在配置iphone进行调试时遇到困难,请记住this important steps from the instructions

  1. 只有在使用USB DEVICE时才需要启用Webinspector选项。您无需在模拟器设备上标记此选项。我don't have it on the simulator和我能够运行webinspector。
  2. 运行模拟器并使用移动safari浏览器打开页面后,您需要打开DESKTOP safari浏览器并通过检查Develop在菜单栏中启用Show develop menu in menu bar

如果在菜单栏中看不到“Develop”,请转到菜单栏并单击“Safari>首选项>高级”,然后选择“在菜单栏中显示开发菜单”复选框。

enter image description here

  1. 从菜单栏Develop -> Simulator or Iphone -> Your Page中选择safari

enter image description here

在开发人员工具栏中,打开指南中显示的Timelines/Network RequestNetwork以检查您的网络请求

检查服务器日志以查看后端是否收到AJAX请求或检查phone simulator日志,因为您可能会看到与证书或其他原因相关的一些错误。您必须在线研究这些错误的解决方案。

当我使用xcode构建项目时,我也能够从xcode中的手机中看到控制台日志

从您的问题,我了解您希望能够在移动设备而不是桌面上进行调试?如果您使用的是iPhone 7或更高版本,可以在WebInspector中打开iPhone settings

转到Settings> Safari> Advanced(它位于屏幕的底部),然后在那里可以打开WebInspector。这样您就可以在iPhone上阅读控制台了。

'WebInspector'是iPhone 7的新功能;较旧的iPhone(6或以下)使用'DebugConsole',可通过“设置”菜单以相同方式访问。 WebInspector的优点是,当iPhone连接到Mac时,您可以在桌面游戏中显示webinspector。 (从Safari菜单中选择“开发”>“显示WebInspector”。

默认情况下,调试控制台和Web检查器都处于禁用状态,因此您需要启用它们

希望这可以帮助
