什么会导致addClass()
/ removeClass()
属性打破流畅的过渡?
以下是我正在使用的当前脚本:
$(document).ready(function() {
var o = 0;
$("a.lbimg > img.lb-click").click(function() {
var s = $("body");
o = $(window).scrollTop(), s.css("position", "fixed"), s.css("top", "-" + o + "px"), s.css("background-position", "0 -" + o + "px"), s.addClass("no-scroll"), $("#lb-view").addClass("target");
}), $("#lb-controls").on("click", function() {
var s = $("body");
s.css("position", ""), s.css("background-position", ""), o = $(window).scrollTop(o), s.removeClass("no-scroll"), $("#lb-view").removeClass("target");
});
});
有点难以解释;但是,这似乎是特定于Safari的问题。
这是主要问题:点击照片后,它会在灯箱窗口中打开图像。然后,在关闭窗口时,body
位置仅在一瞬间跳转/移位,然后再调整回当前窗口滚动位置。从本质上讲,它打破了功能的可见流动性。
