下面是我正在使用的代码，我一直在使用 .mouseenter(function () { 没有问题...我一直在阅读，当您使用 .live() 时，它会将事件应用于现有和新的 dom 元素，但对于某些原因现在该功能根本不起作用，我的语法有问题吗？

    $(document).ready(function(){
    $("div#rows div.row div:nth-child(1)",this).nextUntil('nth-child(2)').on("mouseenter", function() {
        $('img',this).stop().animate({"bottom":"0px"}, "fast"); 
    });
    $('div',this).off("mouseleave").on("mouseleave", function() {
        $('img',this).stop().animate({"bottom":"94px"}, "fast");    
    });

});

$(document).ready(function(){
    $("div#rows div.row div:nth-child(3)",this).nextUntil('nth-child(4)').on("mouseenter", function() {
        $('img',this).stop().animate({"bottom":"0px"}, "fast"); 
    });
    $('div',this).off("mouseleave").on("mouseleave", function() {
        $('img',this).stop().animate({"bottom":"99px"}, "fast");    
});

});

更新代码以使用 .on 而不是 .live ...动画正在使用第一组帖子，但 ajax 加载的所有分页仍然没有触发事件...

要作为委托侦听器执行此操作，第一个选择器应该是 Ajax 内容的祖先。进行 ajax 调用时永远不会破坏的东西。

$('#neverDestroyed').on('mouseenter', '.actualTarget', function() {
  // stuff happens when .actualTarget has mouse enter it
});

老实说，代码有点“太长了；没读过”，但是当应用于您自己的选择器时，上面的代码应该可以解决您的问题。

仍然不确定你想要做什么，但你真的只需要一个文档。准备好，我不明白选择第一个孩子直到第二个孩子等的情况。为什么不把它应用于所有这些，如果动画值发生变化，则使用一组值并根据元素索引、ID 或其他内容获取正确的值。

$(document).ready(function(){
    var elms = $("#rows > .row").children();
    var ani = ['94', '94', '99', '99'];

    $(document).on({
        mouseenter: function(e) {
            $('img', e.target).stop().animate({"bottom":"0px"}, "fast"); 
        },
        mouseleave: function(e) {
            var i = $(this).index();
            $('img', e.target).stop().animate({"bottom": ani[i]}, "fast");
        }
    }, elms);
});
