这篇文章将为大家详细讲解有关HTML中如何实现瀑布流布局,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
第一种方式:使用JavaScript:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>瀑布流布局</title>
<style>
*{padding:0;margin:0;}
.clearfix:after,
.clearfix:before {
content: " ";
display: table;
}
.clearfix:after {
clear: both;
}
.main {
position: relative;
-webkit-column-width: 210px;
-moz-column-width: 210px;
-webkit-column-gap: 5px;
-moz-column-gap: 5px;
}
.box {
float: left;
padding: 15px 0 0 15px;
}
.box .pic {
width: 180px;
height: auto;
padding: 10px;
border-radius: 5px;
box-shadow: 0 0 5px #cccccc;
border: 1px solid #cccccc;
}
.box .pic img {
display: block;
width: 100%;
}
</style>
</head>

<script>
window.onload = function(){
waterfall('main','box');
//模拟json数据
var dataJson = {'data': [{'class="lazy" data-src':'30.jpg'},{'class="lazy" data-src':'31.jpg'},{'class="lazy" data-src':'32.jpg'},{'class="lazy" data-src':'33.jpg'},{'class="lazy" data-src':'34.jpg'},{'class="lazy" data-src':'35.jpg'},{'class="lazy" data-src':'36.jpg'},{'class="lazy" data-src':'37.jpg'},{'class="lazy" data-src':'38.jpg'},{'class="lazy" data-src':'39.jpg'},{'class="lazy" data-src':'40.jpg'},{'class="lazy" data-src':'41.jpg'},{'class="lazy" data-src':'42.jpg'},{'class="lazy" data-src':'43.jpg'},{'class="lazy" data-src':'44.jpg'},{'class="lazy" data-src':'45.jpg'}]};
//监听scroll事件
window.onscroll = function(){
var isPosting = false;
if(checkScollSlide('main','box') && !isPosting){
var oParent = document.getElementById('main');
for(var i in dataJson.data){
isPosting = true;
var oBox = document.createElement('div');
oBox.className = 'box';
oBox.innerHTML = '<div class="pic"><img class="lazy" data-src="./images/'+dataJson.data[i].class="lazy" data-src+'"></div>';
oParent.appendChild(oBox);
}
isPosting = false;
waterfall('main','box');
}
}
}
function waterfall(parent,clsName){
//获取父元素
var oParent = document.getElementById(parent),
//获取所有box
aBoxArr = oParent.getElementsByClassName(clsName),
//单个box宽度
iBoxW = aBoxArr[0].offsetWidth,
// 列数
cols = Math.floor(document.documentElement.clientWidth / iBoxW);
oParent.style.cssText = 'width:'+iBoxW*cols+'px;margin:0 auto;';
//储存所有的高度
var hArr = [];
for(var i = 0; i < aBoxArr.length; i++){
if(i < cols){
hArr[i] = aBoxArr[i].offsetHeight;
}else{
//获取hArr最小值
var minH = Math.min.apply(null,hArr),
// hArr最小值索引index
minHIndex = getMinHIndex(hArr,minH);
aBoxArr[i].style.cssText = 'position:absolute;top:'+minH+'px;left:'+aBoxArr[minHIndex].offsetLeft+'px;';
//添加元素之后更新hArr

}
}
}
//获取最小值索引
function getMinHIndex(arr,val){
for(var i in arr){
if(arr[i] == val){
return i;
}
}
}
//检查是否满足加载数据条件,parent 父元素id clsName 块元素类
function checkScollSlide(parent,clsName){
var oParent = document.getElementById(parent),
aBoxArr = oParent.getElementsByClassName(clsName),
// 最后一个box元素的offsetTop+高度的一半
lastBoxH = aBoxArr[aBoxArr.length - 1].offsetTop + aBoxArr[aBoxArr.length - 1].offsetHeight / 2,
//兼容js标准模式和混杂模式
scrollTop = document.documentElement.scrollTop || document.body.scrollTop,
height = document.documentElement.clientHeight || document.body.clientHeight;
return lastBoxH < scrollTop + height ? true : false;
}
</script>
</body>
</html>
第二种方式:使用jquery:(html结构跟css同上)
$( window ).on( "load", function(){
waterfall('main','box');
//模拟数据json
var dataJson = {'data': [{'class="lazy" data-src':'30.jpg'},{'class="lazy" data-src':'31.jpg'},{'class="lazy" data-src':'32.jpg'},{'class="lazy" data-src':'33.jpg'},{'class="lazy" data-src':'34.jpg'},{'class="lazy" data-src':'35.jpg'},{'class="lazy" data-src':'36.jpg'},{'class="lazy" data-src':'37.jpg'},{'class="lazy" data-src':'38.jpg'},{'class="lazy" data-src':'39.jpg'},{'class="lazy" data-src':'40.jpg'},{'class="lazy" data-src':'41.jpg'},{'class="lazy" data-src':'42.jpg'},{'class="lazy" data-src':'43.jpg'},{'class="lazy" data-src':'44.jpg'},{'class="lazy" data-src':'45.jpg'}]};
window.onscroll=function(){
var isPosting = false;
if(checkscrollside('main','box') && !isPosting){
isPosting = true;
$.each(dataJson.data,function(index,dom){
var $box = $('<div class="box"></div>');
$box.html('<div class="pic"><img class="lazy" data-src="./images/'+$(dom).attr('class="lazy" data-src')+'"></div>');
$('#main').append($box);
waterfall('main','box');
isPosting = false;
});
}
}
});
function waterfall(parent,clsName){
var $parent = $('#'+parent);//父元素
var $boxs = $parent.find('.'+clsName);//所有box元素
var iPinW = $boxs.eq( 0 ).width()+15;// 一个块框box的宽
var cols = Math.floor( $( window ).width() / iPinW );//列数
$parent.width(iPinW * cols).css({'margin': '0 auto'});
var pinHArr=[];//用于存储 每列中的所有块框相加的高度。
$boxs.each( function( index, dom){
if( index < cols ){
pinHArr[ index ] = $(dom).height(); //所有列的高度
}else{
var minH = Math.min.apply( null, pinHArr );//数组pinHArr中的最小值minH
var minHIndex = $.inArray( minH, pinHArr );
$(dom).css({
'position': 'absolute',
'top': minH + 15,
'left': $boxs.eq( minHIndex ).position().left
});
//添加元素后修改pinHArr
pinHArr[ minHIndex ] += $(dom).height() + 15;//更新添加了块框后的列高
}
});
}
//检验是否满足加载数据条件,即触发添加块框函数waterfall()的高度:最后一个块框的距离网页顶部+自身高的一半(实现未滚到底就开始加载)
function checkscrollside(parent,clsName){
//最后一个块框
var $lastBox = $('#'+parent).find('.'+clsName).last(),
lastBoxH = $lastBox.offset().top + $lastBox.height()/ 2,
scrollTop = $(window).scrollTop(),
documentH = $(document).height();
return lastBoxH < scrollTop + documentH ? true : false;
}
第三种方式:使用css:(html结构同上)
.clearfix:after,
.clearfix:before {
content: " ";
display: table;
}
.clearfix:after {
clear: both;
}
.main {
position: relative;
[color=#ff0000]-webkit-column-width: 210px;
-moz-column-width: 210px;
-webkit-column-gap: 5px;
-moz-column-gap: 5px;[/color]
}
.box {
float: left;
padding: 15px 0 0 15px;
}
.box .pic {
width: 180px;
height: auto;
padding: 10px;
border-radius: 5px;
box-shadow: 0 0 5px #cccccc;
border: 1px solid #cccccc;
}
.box .pic img {
display: block;
width: 100%;
}
瀑布流实现方式比较:
Javascript原生方式/jquery方式
1、需要计算,列数 = 浏览器窗口宽度/图片宽度,图片定位是根据每一列的高度计算下来图片的位置;
2、图片排序是按照图片计算的位置横向排列,位置是计算出来的,比较规范
Css方式
1、不需要计算,浏览器自动计算,只需设置列宽,性能高;
2、列宽随着浏览器窗口大小进行改变,用户体验不好;
3、图片排序按照垂直顺序排列,打乱图片显示顺序;
4、图片加载还是依靠javascript/jquery实现
