下面是我正在使用的代码，我一直在使用.mouseenter（function（）{没有问题...我一直在阅读当你使用.live（）时它将事件应用于现有的＆amp; new dom元素，但由于某种原因，现在函数根本不起作用，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，但是ajax加载了分页的所有内容仍然没有触发事件...

要将此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。在进行ajax调用时永远不会被破坏的东西。
$('#neverDestroyed').on('mouseenter', '.actualTarget', function() {
// stuff happens when .actualTarget has mouse enter it
});
代码有点“太久了;如果我是诚实的话，没有阅读”，但是当应用于你自己的选择器时，上面应该把你排除在外。

仍然不确定你想做什么，但你真的只需要一个文件。已经，我不知道如何选择第一个孩子直到第二个孩子等等。为什么不把它应用到所有这些，如果动画值更改使用值数组并根据元素索引，ID或其他方式获取正确值。
$(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);
});
