Safari for Ipad not reporting line numbers on Javascript errors

问题

I am using iPad 2 with IOs 5 to develop a web application.

I have enabled the developer console to get logs , but when javascript error occurs it does not include corresponding line number.

Since the web application handles touch and gesture events, I cannot test them on desktop version of the browser!

Any help will be appreciated.

You can add a window level error handler

and have that console log the line number. You'll be getting two console logs per error, but you will have more control over the output.

You can try using regular Safari or Chrome and write it there first before using the iPad or alternatively there is the Weinre application that provides you a console like firebug / chrome developer tools.
