我尝试使用jQuery淡出滚动div(而不是主窗口)中的元素,因为它们滚出视图。我正在使用fadeTo函数并在用户滚动时检查元素的位置。
See this stackoverflow thread for what I'm basing my code on
我的非视网膜监视器(使用Chrome)似乎一切正常。顶部元素正在滚动div的顶部淡出,就像它应该的那样。
然而,当我使用我的macbook pro w / retina显示器执行相同的操作时,我会得到奇怪的行为。对于滚动div中的某些元素(不是全部),fadeTo动画仅淡化div的一部分(底部)。上半部分(或更多部分)没有变化。
编辑:WAS ABLE TO MAKE A DEMO(尝试在显示器与视网膜屏幕上观看演示)。
知道为什么会这样吗?为什么我的视网膜屏幕上的表现与我的显示器上的表现不同(两者都使用相同版本的Chrome)?
我还应该提到所有这些html都被注入到现有的网页中,因此滚动div位于页面顶部的右上角(固定位置)。我正在构建Chrome扩展程序......我的代码:
$('#volleyThreadDiv' + objectId).scroll(function() {
console.log('userDidscroll...');
$('.volleyComment').each(function () {
var height = $(this).css('height');
var heightNumeric = height.substring(0, height.length - 2);
heightNumeric = Number(heightNumeric);
if ($(this).position().top + heightNumeric < 130) {
$(this).stop().fadeTo(0, 0.2);
} else {
$(this).stop().fadeTo(0, 100);
}
});
$('.volleyReply').each(function () {
var height = $(this).css('height');
var heightNumeric = height.substring(0, height.length - 2);
heightNumeric = Number(heightNumeric);
if ($(this).position().top + heightNumeric < 130) {
$(this).stop().fadeTo(0, 0.2);
} else {
$(this).stop().fadeTo(0, 100);
}
});
});

答案 0 :(得分:0)
我找到的解决方案是在.volleyCommentStatus,.volleyReplyStatus的css中添加 position:relative 。
它似乎是继承位置:静态,我认为是导致视网膜屏幕问题。
