I need to check with jQuery if a DIV element is not falling off-screen. The elements are visible and displayed according CSS attributes, but they could be intentionally placed off-screen by:
position: absolute;
left: -1000px;
top: -1000px;
我不能使用jQuery :visible
Select 器,因为元素的高度和宽度都不是零.
I am not doing anything fancy. This absolute position placement is the way my Ajax framework implements the hide/show of some widgets.
