我创建了以下 HTML。黄色框包含图像缩略图。当我将鼠标悬停在缩略图上时，它会在缩略图顶部显示一个视图链接。

但是如果我快速移动鼠标，我会让链接 div 闪烁。

这是代码 - 您可以将其复制并粘贴为 html 并进行测试。

        $(document).ready(function () {

            $('.divImage').mouseenter(function () {
                var vl = $('#viewlink');
                var vlpos = $(this).position();
                vl.css({ 'top': (vlpos.top + ($(this).height() - vl.height())), 'left': vlpos.left, position: 'absolute' });
                vl.fadeTo('1', 0.5);
                vl.css('display', 'block');
            });

            $('.divImage').mouseleave(function (event) {
                if (event.toElement.id != 'viewlink') {
                    var vl = $('#viewlink');
                    vl.fadeTo('1', 0.0, function () {

在 FF 4.0 中也没有调用 mouseleave。有任何想法吗？

我猜你在动画队列中遇到了堆积。通过在任何其他动画调用之前调用stop()来防止这种情况。

您编辑的代码（注意stop()在 each 之前添加fadeTo()）：

$('.divImage').mouseenter(function () {
            var vl = $('#viewlink');
            var vlpos = $(this).position();
            vl.css({ 'top': (vlpos.top + ($(this).height() - vl.height())), 'left': vlpos.left, position: 'absolute' });
            vl.stop(true,true).fadeTo('1', 0.5);
            vl.css('display', 'block');
        });

        $('.divImage').mouseleave(function (event) {
            if (event.toElement.id != 'viewlink') {
                var vl = $('#viewlink');
                vl.stop(true,true).fadeTo('1', 0.0, function () {
                    vl.css('display', 'block');
                });
            }
        });

        $('#viewlink').mouseleave(function (event) {
            $(this).stop(true,true).fadeTo('1', 0.0, function () {
                $(this).css('display', 'block');
            });

});

hover()没有闪烁效果更好。

$('.divImage').hover(enter, leave);

function enter() { // mouse enter
    var vl = $('#viewlink');
    var vlpos = $(this).position();
    vl.css({ 'top': (vlpos.top + ($(this).height() - vl.height())), 'left': vlpos.left, position: 'absolute' });
    vl.fadeTo('1', 0.5);
    vl.css('display', 'block');
};

function leave(event) { // mouse leave
if (event.toElement.id != 'viewlink') {
         var vl = $('#viewlink');
         vl.fadeTo('1', 0.0, function () {
         vl.css('display', 'block');
       });
    }
};

您可以更改 css 属性“可见性”
$(".element").addClass("visible");
：
.hidden { visibility: hidden; } .visible { visibility: visible; }

希望这可以帮助！
