avalonjs制作响应式瀑布流特效

　 布局不是基于float，也不是基于绝对定位，看最下面的html,css就知道了。也没有满篇烦人的html插入，代码很清爽

function getIndex(index) {
  if (index < 10) {
    index = "00" + index;
  } else if (index < 100) {
    index = "0" + index;
  }
  return index;
}
var $ = function(id) {
  return document.getElementById(id);
};
require([ "avalon-min" ], function(avalon) {
  var waterfall = {
      load_items : null,
      loaded_items:[],
      col_num : 0,// 列数
      waterfall_model : null,
      col_width : 200,
      loaded_num : 0,
      init_num : 0,
      loading : false,
      start:0,
      resizing:false,
      find_shortest_col : function() {
      // 找出最小高度的列
        var a = avalon($('row0')).height(), min_i = 0;
        for ( var i = 1; i < this.col_num; i++) {
          var b = avalon($('row' + i)).height();
          if (b < a) {
            min_i = i;
            a = b;
          }
        }
        return min_i;
      },
      init : function(data) {
        this.load_items = data;
        this.loaded_items=this.loaded_items.concat(data);
        this.waterfall_model = waterfall_model;
        this.col_num = Math.floor(avalon(window).width()
            / this.col_width);
        this.init_num = this.col_num;
        for ( var j = 0; j < this.col_num; j++) {
          waterfall_model.img_list.push([]);
        }
        for ( var j = 0; j < this.col_num; j++) {
         // 第一行图片
          var a={};
          a.src=getIndex(data[j].src);
          a.height=data[j].height;
          a.text=data[j].text;
          waterfall_model.img_list[j].push(a);
        }
        this.start=this.col_num;
      },
      add_item : function(i) {
        var a = this.find_shortest_col();
        var b={};
        var c=this.load_items[this.init_num+i];
        if(c){
          b.src=getIndex(c.src);
          b.height=c.height;
          b.text=c.text;

          waterfall_model.img_list[a].push(b);
        }
      }
    };
    var waterfall_model = avalon.define("waterfall",function(vm) {// vm
              vm.img_list = [];
              vm.rendered = function() {// 每次图片加载渲染后执行
                 
                if(waterfall.resizing){
                  if (waterfall.loaded_num+ waterfall.init_num= 199) {
      waterfall.col_num = Math.floor(avalon(window).width()
