Description
Fixed logic that causes the value to become 1 if colorpicker alpha slider slides to the leftmost and causes value to be 0 to form false.

undefined
andnull
types because0
is a valid value for colorpicker, not false.The solution is to use
! =
to judge onlyundefined
andnull
to make0
a valid valueclosed #17322
