Question

我正在尝试创建一个照片列表，当您将鼠标悬停在它们上面时，它们应该放大。但是，出于某种原因，我无法让它们放大。我在顶部添加了一张相同类别的照片，这些照片放大了，所以我很困惑。

var tags = $("input[type='radio'][name='radio']:checked").val();
getPictures();
var src;

<!-- handles the radio button input then calls getPictures
$("input[name='radio']").change(function(){
    tags = $("input[type='radio'][name='radio']:checked").val();
    $('#images').empty();
    getPictures();

<!-- jQuery function to get the flickr photos

            <!-- return 3 columns
            if( i % 3 == 0 && i != 0)
                $("#images").append("<br />");

您动态插入.resize张图片，这意味着他们在页面加载后出现。要为事件创建监听器，请使用以下命令：

$('body').on('mouseenter', '.resize', function(){ ... })

对于mouseleave也一样。
