I'm trying to set focus to a particular edit field when a page opens or button is pressed. The following simple HTML/Javascript (Test.html) works with Firefox and Chrome but not Safari. Safari will clear the text with the clear button and post it with find button but not select it when the select button is pressed. Any help would be appreciated. (iOS 7 on an iPad 2)
Update -- Replaced with working code
