原生的javascript图片瀑布流实现，具体代码如下：

(function($){

$.fn.niceWall = function(options){

$.fn.niceWall.defaults = {

"wrap":"body",

"width":200,

"gap":10,

"url":"",

"count":null,

"callback":null

};

var opts = $.extend({},$.fn.niceWall.defaults ,options || {});

//

return this.each(function(){

var $this = $(this);

var colspanW = opts.width + opts.gap;

var arrX = [];

var arrY = [];

var iPage = 0;

var iBtn = true;

var colspan = Math.floor($(opts.wrap).innerWidth() / colspanW);

//

function setLayer(){

colspan = Math.floor($(window).innerWidth() / colspanW);

$this.css("width",colspanW * colspan - opts.gap);

for(var i = 0; i < colspan;i++){

arrX[i] = colspanW * i;

arrY[i] = 0;

}

};

setLayer();

//

function render(){

if(!iBtn) return;

iPage++;

iBtn = false;

$.getJSON(opts.url,{page:iPage},function(data){

$.each(data,function(index,element){

console.log(element)
