首先我们在#container放置多个.grid

<div class="grid"> 
   <div class="img_area"> 
    <img class="lazy" src="images/pixel.gif" data-original="images/1.jpg" width="175" /> 
   </div>

   </div> 
  </div> 
  <div class="grid"> 
   <div class="img_area"> 
    <img class="lazy" src="images/pixel.gif" data-original="images/2.jpg" width="175" /> 
   </div>

   </div> 
</div> 
......

接着同样我们在#test放置多个.grid，用于滚动加载复制。

<div id="test" style="display: none;"> 
   <div class="grid"> 
    <div class="img_area"> 
     <img class="lazy" src="images/pixel.gif" data-original="images/1.jpg" width="175" /> 
    </div>

    </div> 
   </div> 
   ......
</div>

引入jQuery库、懒加载插件lazyload及瀑布流插件blocksit.min.js

<script type="text/javascript" src="jquery.js"></script> 
<script type="text/javascript" src="js/jquery.lazyload.min.js"></script> 
<script type="text/javascript" src="js/blocksit.min.js"></script>

懒加载

$("img.lazy").lazyload({
    load: function() {
        $('#container').BlocksIt({
            numOfCol: 5,
            offsetX: 8,
            offsetY: 8
        });
    }
});

滚动时加载

$(window).scroll(function() {
    // 当滚动到最底部以上50像素时， 加载新内容
    if ($(document).height() - $(this).scrollTop() - $(this).height() < 50) {
        $('#container').append($("#test").html());
        $('#container').BlocksIt({
            numOfCol: 5,
            offsetX: 8,
            offsetY: 8
        });
        $("img.lazy").lazyload();
    }
});

//window resize
var currentWidth = 1100;
$(window).resize(function() {
    var winWidth = $(window).width();
    var conWidth;
    if (winWidth < 660) {
        conWidth = 440;
        col = 2
    } else if (winWidth < 880) {
        conWidth = 660;
        col = 3
    } else if (winWidth < 1100) {
        conWidth = 880;
        col = 4;
    } else {
        conWidth = 1100;
        col = 5;
    }

    if (conWidth != currentWidth) {
        currentWidth = conWidth;
        $('#container').width(conWidth);
        $('#container').BlocksIt({
            numOfCol: col,
            offsetX: 8,
            offsetY: 8
        });
    }
});
