Is there some kind of developer toolbar that can be used within the iPad/Safari?
I am aware of the same on desktop Safari as well as I know there is a Debugger optio
On the ipad go to *Settings > Safari > Advanced * and activate the Web Inspector.
Connect your ipad with your computer.
On your computer open Safari, enable the developer tools in the settings. check the above menu for the tab Developer and find your iPad there.
Full control via console from your desktop machine over the iOS Safari and you're done!
PS: This works exact the same way with the iPhone as well..
