jquery - 如何平滑地淡化元素的高度？

问题描述

我尝试在点击时淡出我的元素。但问题是，我想要它流畅，但高度在褪色后有点跳跃。有没有像垂直平滑褪色的选项？

这是一个堆栈片段：

$(".collapse-content").each(function() {
    if (!$(this).closest(".collapse-head").hasClass("active")) {
        $(this).hide();
    }
});

$('.collapse-head').hover(
    function() {
        $(this).find("blockquote").css({
            "color": "#000"
        });
    },

    function() {
        $(this).find("blockquote").css({
            "color": "#777"
        });
    }
);
$(".collapse-head").click(function() {
    $(".collapse-head").removeClass("active");
    $(this).addClass("active");
    $(".collapse-content").fadeOut("slow");
    $(this).find(".collapse-content").fadeIn("slow");
});
.collapse-head {
    cursor: pointer;
}

解决方案

@freedomn-m 说的是真的，但我认为问题出在.collapse content. 这个怎么样？

$(".collapse-head").click(function() {
    $(".collapse-head").removeClass("active");
    $(".collapse-content").slideUp(1400);
    $(this).addClass("active");
    $(".collapse-content").fadeOut(1400);
    $(this).find(".collapse-content").fadeIn(1400);
});

我slideUp为.collapse-content $(".collapse-content").slideUp(1400);
