Jquery事件在Ajax分页后不起作用

Question

下面是我正在使用的代码，我一直在使用.mouseenter(function () ){没有问题...我一直在读到，当你使用.live()时，它会将事件应用于现有的和新的dom元素，但由于某种原因，该函数现在根本不起作用了，是不是我的语法有问题？

    $(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");    
});

});

已更新代码以使用.on而不是.live...动画正在处理第一组帖子，但是ajax使用分页加载的所有内容仍然不会触发事件……

已添加html :\

Answer 1

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。一些在进行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
});

说实话，这段代码有点“太长了；没读过”，但当应用于你自己的选择器时，上面的代码应该会把你理清头绪。

我仍然不确定你想要做什么，但是你只需要一个document.ready，我不明白选择第一个孩子有什么问题，直到第二个孩子，等等。为什么不把它应用到所有的孩子，如果动画值改变，使用一个值的数组，并根据元素索引，ID或其他东西获得正确的值。

$(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);
});
