Question

在OS X版Chrome中，图像不透明度上下变化。在Windows版本中不会发生这种情况。我该怎么办才能修复它？我根本不想要不透明度。

function theRotator() {
//Set the opacity of all images to 0
$('div.rotator ul li').css({opacity: 0.0});

//Get the first image and display it (gets set to full opacity)
$('div.rotator ul li:first').css({opacity: 1.0});

//Call the rotator function to run the slideshow, 6000 = change to next image after 6 seconds

setInterval('rotate()',6000);

}

function rotate() { 
//Get the first image
var current = ($('div.rotator ul li.show')?  $('div.rotator ul li.show') : $('div.rotator ul li:first'));

if ( current.length == 0 ) current = $('div.rotator ul li:first');

//Get next image, when it reaches the end, rotate it back to the first image
var next = ((current.next().length) ? ((current.next().hasClass('show')) ? $('div.rotator ul li:first') :current.next()) : $('div.rotator ul li:first'));

//Un-comment the 3 lines below to get the images in random order

//var sibs = current.siblings();
    //var rndNum = Math.floor(Math.random() * sibs.length );
    //var next = $( sibs[ rndNum ] );


//Set the fade in effect for the next image, the show class has higher z-index
next.css({opacity: 0.0})
.addClass('show')
.animate({opacity: 1.0}, 0);

//Hide the current image
current.animate({opacity: 0.0}, 0)
.removeClass('show');

};



$(document).ready(function() {      
//Load the slideshow
theRotator();
$('div.rotator').fadeIn(1000);
$('div.rotator ul li').fadeIn(1000); // tweek for IE
});

我不确定为什么Mac和Windows版本的Chrome会有所不同，但是这些行是造成不透明度衰退的原因：

//Set the fade in effect for the next image, the show class has higher z-index
next.css({opacity: 0.0})
.addClass('show')
animate({opacity: 1.0}, 0);

//Hide the current image
current.animate({opacity: 0.0}, 0)
.removeClass('show');

如果你想跳过褪色并直接从一张图片切换到另一张图片，我很确定你可以用以下内容替换整个部分：

current.removeClass('show');
next.addClass('show');

旋转滑块中的不透明度会改变Chrome OSX中的不透明度，但不会在Windows中更改
