iphone does not support keyboard events

Recently in the Mobile Web page, there is such a need to listen to a phone input box, when the phone input to 11 for the time, the button enabled

I've been listening to the KeyUp event, and there's nothing wrong with the Android phone

But on a proud iphone, it doesn't work.

On-line search data good, it is said that the iphone installed third-party input method, the key event can not be used

Then fortunately there is an input event that can be replaced.

When input gets the focus, it is sometimes obscured by the keypad, when we can get the height of the page, and when input gets the focus, the page height is set so that input can be propped up.
