回答1:

Change the selector of each position to: $(this).children(".class")

for example the code $(".fromTopToBottom") will change to $(this).children(".fromTopToBottom")

回答2:

very simple, use $(this), for example

$('.mydivclass').mouseover(function(e){
    $(this).css('color','gray'); // Current element
});

If divs are nested then you should use e.stopPropagation() to stop the event bubling.

回答3:

What you need is a "current" div concept.

1. At the beginning of mouseenter handler:

   $(".trbl").removeClass("current"); $(this).addClass("current");

2. In your case statement, $(".fromTopToBottom").css({...}) -> $(".current .fromTopToBottom").css({...})

For the effect check out http://jsfiddle.net/Qw7bw/7/

回答4:

Use $(this).find(x) rather than $(x) directly when selecting ".fromTopToBottom" and similar classes. This allows jQuery to only select childs of the hovered element http://jsfiddle.net/Qw7bw/6/

回答5:

Use $(this).children(".fromTopToBottom") instead of $(".fromTopToBottom").

This will select divs of the given class inside the element whose handler you are writing.
