我想要的瀑布流是從數據庫裡讀取，但網頁進來時不會顯示全部圖片，往下滑動時才會顯示其他圖片。而這種它一次就把所有圖片讀取，滑動到底部也只是重復一遍而已。
一般瀑布流插件有配置支持動態從數據庫中讀取數據的，你認真看下API。
如果確認你的這個不支持動態讀取，只能換一個瀑布流插件了，如這個：
(function ($) {
var
//參數
setting = {
column_width: 240, //列寬
column_className: 'waterfall_column', //列的類名
column_space: 10, //列間距
cell_selector: '.cell', //要排列的磚塊的選擇器，context為整個外部容器
img_selector: 'img', //要加載的圖片的選擇器
auto_imgHeight: true, //是否需要自動計算圖片的高度
fadein: true, //是否漸顯載入
fadein_speed: 600, //漸顯速率，單位毫秒
insert_type: 1, //單元格插入方式，1為插入最短那列，2為按序輪流插入
getResource: function (index) { } //獲取動態資源函數,必須返回一個磚塊元素集合,傳入參數為加載的次數
},
//
waterfall = $.waterfall = {}, //對外信息對象
$waterfall = null; //容器
waterfall.load_index = 0, //加載次數
$.fn.extend({
waterfall: function (opt) {
opt = opt || {};
setting = $.extend(setting, opt);
$waterfall = waterfall.$waterfall = $(this);
waterfall.$columns = creatColumn();
render($(this).find(setting.cell_selector).detach(), false); //重排已存在元素時強制不漸顯
waterfall._scrollTimer2 = null;
$(window).bind('scroll', function () {
clearTimeout(waterfall._scrollTimer2);
waterfall._scrollTimer2 = setTimeout(onScroll, 300);
});
waterfall._scrollTimer3 = null;
$(window).bind('resize', function () {
clearTimeout(waterfall._scrollTimer3);
waterfall._scrollTimer3 = setTimeout(onResize, 300);
});
}
});
function creatColumn() {//創建列
waterfall.column_num = calculateColumns(); //列數
//循環創建列
var html = '';
for (var i = 0; i < waterfall.column_num; i++) {
html += '<div class="' + setting.column_className + '" style="width:' + setting.column_width + 'px; display:inline-block; *display:inline;zoom:1; margin-left:' + setting.column_space / 2 + 'px;margin-right:' + setting.column_space / 2 + 'px; vertical-align:top; overflow:hidden"></div>';
}
$waterfall.prepend(html); //插入列
return $('.' + setting.column_className, $waterfall); //列集合
}

配置getResource即可。。自己用ajax讀出數據後調用render回調即可
var totalpage = 1;//從數據庫中讀取總頁數賦值給這個js變量，如<%=你的服務器端變量名%>
function getResource(index, render) { if (index + 1 > totalpage || opt.loading) return false; opt.loading = true; $.ajax({ url: '動態頁地址', data: { page: index + 1, pagesize: 8}, type: 'POST', complete: function (xhr) { opt.loading = false; $('#pLoading').hide(); render($(xhr.responseText)); } }); }
var opt = { auto_imgHeight: true, insert_type: 1 };
if (totalpage > 1) opt.getResource = getResource;
$('#waterfall').waterfall(opt);
