waterfall.js
window.onload=function(){
waterFall('main','box');
//模擬後台相應數據json

{"src":"1.jpg"},
{"src":"2.jpg"},
{"src":"3.jpg"},
{"src":"4.jpg"},
{"src":"5.jpg"},
{"src":"6.jpg"}
]
}
window.onscroll=function(){
if(checkScrollSlide){
//將數據塊渲染到當前頁面的尾部
var oParent=document.getElementById("main");
for(var i=0;i<dataInt.data.length;i++){
var oBox=document.createElement("div");
oBox.className="box";
oParent.appendChild(oBox);
var oPic=document.createElement("div");

}
function waterFall(parent,box){
//將main下的class為box的所有元素取出來
var oParent=document.getElementById(parent);
var oBoxs=getByClass(oParent,box);
console.log(oBoxs.length);
//計算整個頁面顯示的列數（頁面寬/box寬）
var oBoxW=oBoxs[0].offsetWidth;
// console.log(oBoxW);
var cols=Math.floor(document.documentElement.clientWidth/oBoxW);
// console.log(cols);
//設置main的寬
oParent.style.cssText="width:"+oBoxW*cols+"px;margin:0 auto;"
var hArr=[];//存放每列高度的數組
for(var i=0;i<oBoxs.length;i++){
if(i<cols){
hArr.push(oBoxs[i].offsetHeight);
}else{
var minH=Math.min.apply(null,hArr);//獲取當前數組最小高度值

hArr[index]+=oBoxs[i].offsetHeight;//變化數組列的高度值，因為加上了一張圖片
}

//根據class獲取元素

//console.log(scrollTop);
var height=document.body.clientHeight||document.documentElement.clientHeight;//混雜模式和標准模式下的浏覽器窗口高度獲取
return (lastBoxH<scrollTop+height)?true:false;//檢測最後一個box高度是否小於滾動高度+窗口高度，返回布爾值
}
二、JQuery
$( window ).on( "load", function(){
waterfall('main','pin');
var dataInt={'data':[{'src':'1.jpg'},{'src':'2.jpg'},{'src':'3.jpg'},{'src':'4.jpg'}]};
window.onscroll=function(){
if(checkscrollside()){
$.each( dataInt.data, function( index, value ){
var $oPin = $('<div>').addClass('pin').appendTo( $( "#main" ) );
var $oBox = $('<div>').addClass('box').appendTo( $oPin );
$('<img>').attr('src','./images/' + $( value).attr( 'src') ).appendTo($oBox);
});
waterfall();
};
}
});
/*
parend 父級id
pin 元素id
*/
function waterfall(parent,pin){
var $aPin = $( "#main>div" );
var iPinW = $aPin.eq( 0 ).width();// 一個塊框pin的寬
var num = Math.floor( $( window ).width() / iPinW );//每行中能容納的pin個數【窗口寬度除以一個塊框寬度】
//oParent.style.cssText='width:'+iPinW*num+'px;ma rgin:0 auto;';//設置父級居中樣式：定寬+自動水平外邊距
$( "#main" ).css({
'width:' : iPinW * num,
'margin': '0 auto'
});
var pinHArr=[];//用於存儲 每列中的所有塊框相加的高度。
$aPin.each( function( index, value ){
var pinH = $aPin.eq( index ).height();
if( index < num ){
pinHArr[ index ] = pinH; //第一行中的num個塊框pin 先添加進數組pinHArr
}else{
var minH = Math.min.apply( null, pinHArr );//數組pinHArr中的最小值minH
var minHIndex = $.inArray( minH, pinHArr );
$( value ).css({
'position': 'absolute',
'top': minH + 15,
'left': $aPin.eq( minHIndex ).position().left
});
//數組 最小高元素的高 + 添加上的aPin[i]塊框高
pinHArr[ minHIndex ] += $aPin.eq( index ).height() + 15;//更新添加了塊框後的列高
}
});
}
function checkscrollside(){
var $aPin = $( "#main>div" );
var lastPinH = $aPin.last().get(0).offsetTop + Math.floor($aPin.last().height()/2);//創建【觸發添加塊框函數waterfall()】的高度：最後一個塊框的距離網頁頂部+自身高的一半(實現未滾到底就開始加載)
var scrollTop = $( window ).scrollTop()//注意解決兼容性
var documentH = $( document ).height();//頁面高度
return (lastPinH < scrollTop + documentH ) ? true : false;//到達指定高度後 返回true，觸發waterfall()函數
}
三、CSS多欄布局
.container{
-webkit-column-width:160px;
-moz-column-width:160px;
-webkit-column-gap:5px;
-moz-column-gap:5px;
}
/*數據塊 磚塊*/
.container div{width:160px;
margin:4px 0;}
【css3和js實現方法比較】
--css3方式--
1：不需要計算，浏覽器自動計算，只需設置1列寬，性能高
2:列寬隨著浏覽器寬口大小進行改變，用戶體驗不好；
3：圖片排序按照垂直順序排列，打亂圖片顯示順序
4.圖片加載還是需要js
--js方式--
js實現的瀑布流不會有上面的缺點，但是性能相對要差！
