.append() 之后的 JQuery Lazyload 图像

Question

我正在使用 .append() 将图像加载到 div 中

如何在这些新附加的图像上使用惰性加载器插件？有办法做到吗？

更新:这是代码

//This is a live search script, type something in #livesearch input and it populates a #results ul list with the results
$('#livesearch').live('keyup', function(event) {
    //after ke press detected immediately clear the results div of any previous content
    $('#results').html("");
    // Use the inputed letters to send off an ajax request
    $.getJSON("http://xxxxxx.com/live/" + $(this).val(), function(resp){
            //the ajax returns a json object, next loop through the object and print out the results in a list using append
            $.each(resp.response.docs, function(index, item) {  
            $('#results').append("<li><div style='background-color:rgb(31,31,31);padding:15px;color:rgb(255,255,255);'><span class='inline' style='width:125px;height:50px;margin-right:15px'><img data-original='img/"+item.nameid+".png' src='img/grey.gif' class='lazy' style='display:inline' height='50px'></span><span class='inline' style='width:300px;'><div style='font-size:14px;'>"+item.name+"</div><div style='font-size:12px;color:rgb(99,99,99)'>Strategy | 4 months ago | Played 2,000 times</div></span></div></li>");
        });
    });

    // The list that was created includes images and could have several hundred of them, therefore I would like to lazy load them as you scroll down
    // This line of code is just one of my failed attempts
    $("img.lazy").lazyload();
});

因为图像是在文档加载后添加的，我认为惰性加载器插件很难“看到”原始 HTML 中的图像，因为它们在那里不存在。也许 LazyLoad 无法完成我想要的事情。

从 getJSON 回调中调用lazyload()

$.getJSON("http://xxxxxx.com/live/" + $(this).val(), function(resp){
    $.each(resp.response.docs, function(index, item) {  
        $('#results').append("<li>... \
            <img data-original='img/"+item.nameid+".png' \
            src='img/grey.gif' class='lazy' /> \
            ...</li>");
        });
    });
    $("img.lazy").lazyload().removeClass("lazy");
});

添加 .removeClass("lazy") 可防止延迟加载多次绑定(bind)到同一元素。
