waitElement

The array["exist", "not exist"] contains "selector or xpath of element must exist (for some lazyload element)" & "selector or xpath of element must not exist (for some loading placeholder which need scroll into view to load)"

Example:

"waitElement": [ ".summary", "#popular.fade:not(.in)" ] 

Repeated checking before ".summary" appeared and "#popular.fade:not(.in)" disappeared.

"waitElement": ".summary" 

Repeated checking before ".summary" appeared

"waitElement": "!#popular.fade:not(.in)" # same as "waitElement": [ "", "#popular.fade:not(.in)" ] 

Repeated checking before "#popular.fade:not(.in)" disappeared.

When you set 'waitElement', it's same as the 'wait', that means current rule will effect when url is matched. You can leave a "" when you don't want to set "exist" or "not exist", when you set a "not exist", pagetual will try to trigger lazy load of target element
