PHP+Jquery combined with ajax to achieve drop-down and fade-out waterfall flow effect [no plug-in required]

Introduction:

Waterfall flow, also known as waterfall flow layout. It is a popular website page layout. The visual performance is a jagged multi-column layout. As the page scroll bar scrolls down, this layout will continuously load data blocks and append them to the current tail. The first website to adopt this layout was Pinterest, which gradually became popular in China. Most domestic fresh websites are basically of this style, such as Huaban.com, Mogujie, Meilishuo, etc.

No nonsense, just go to the code. The entire code is divided into two sections of code. The specific code is as follows.

Front desk

$category=$this->getMyVal('category',$_GET);
$xiaohuaList=Xiaohua::model()->getXiaohao($category); //打开页面默认显示的数据
?>



id;?>

title);?>
content;?>
分享

Backstage:

public function actionListXiaohua() {
$xiaohuaList=Xiaohua::model()->getXiaohua();//获取笑话信息
echo CJSON::encode($xiaohuaList);
}

js:

   
;(function($){
var
//参数
setting={
column_width:240,//列宽
column_className:'waterfall_column',//列的类名
column_space:2,//列间距
cell_selector:'.cell',//要排列的砖块的选择器，context为整个外部容器
img_selector:'img',//要加载的图片的选择器
auto_imgHeight:true,//是否需要自动计算图片的高度
fadein:true,//是否渐显载入
fadein_speed:600,//渐显速率，单位毫秒
insert_type:1, //单元格插入方式，1为插入最短那列，2为按序轮流插入
getResource:function(index){ } //获取动态资源函数,必须返回一个砖块元素集合,传入参数为加载的次数
},
//
waterfall=$.waterfall={},//对外信息对象
$waterfall=null;//容器
waterfall.load_index=0, //加载次数
$.fn.extend({
waterfall:function(opt){
opt=opt||{};
setting=$.extend(setting,opt);
$waterfall=waterfall.$waterfall=$(this);
waterfall.$columns=creatColumn();
render($(this).find(setting.cell_selector).detach(),false); //重排已存在元素时强制不渐显
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(){//创建列
waterfall.column_num=calculateColumns();//列数
//循环创建列
var html='';
