Jquery瀑布流布局
瀑布流布局最近真的很流行,很多人都跟我一样想知道是怎么做出来的吧,经过网上搜索大量的参考结合N边的实验今天终于被我写出来了,为了便于大家理解我使用了jQuery(当然用源生js代码执行的效率会高一些,但是很多人多源生js不是很熟练)。

/*
原理:1.把所有的li的高度值放到数组里面
2.第一行的top都为0
3.计算高度值最小的值是哪个li
4.把接下来的li放到那个li的下面

var margin = 10;//这里设置间距
var li=$("li");//这里是区块名称
var li_W = li[0].offsetWidth+margin;//取区块的实际宽度(包含间距,这里使用源生的offsetWidth函数,不适用jQuery的width()函数是因为它不能取得实际宽度,例如元素内有pandding就不行了)
function liuxiaofan(){//定义成函数便于调用
var h=[];//记录区块高度的数组
var n = document.documentElement.offsetWidth/li_W|0;//窗口的宽度除以区块宽度就是一行能放几个区块
for(var i = 0;i < li.length;i++) {//有多少个li就循环多少次
li_H = li[i].offsetHeight;//获取每个li的高度
if(i < n) {//n是一行最多的li,所以小于n就是第一行了
h[i]=li_H;//把每个li放到数组里面
li.eq(i).css("top",0);//第一行的Li的top值为0
li.eq(i).css("left",i * li_W);//第i个li的左坐标就是i*li的宽度
}
else{
min_H =Math.min.apply(null,h) ;//取得数组中的最小值,区块中高度值最小的那个
minKey = getarraykey(h, min_H);//最小的值对应的指针
h[minKey] += li_H+margin ;//加上新高度后更新高度值
li.eq(i).css("top",min_H+margin);//先得到高度最小的Li,然后把接下来的li放到它的下面
li.eq(i).css("left",minKey * li_W); //第i个li的左坐标就是i*li的宽度
}
$("h3").eq(i).text("编号:"+i+",高度:"+li_H);//把区块的序号和它的高度值写入对应的区块H3标题里面
}
}
/* 使用for in运算返回数组中某一值的对应项数(比如算出最小的高度值是数组里面的第几个) */
function getarraykey(s, v) {for(k in s) {if(s[k] == v) {return k;}}}
/*这里一定要用onload,因为图片不加载完就不知道高度值*/
window.onload = function() {liuxiaofan();};
/*浏览器窗口改变时也运行函数*/
window.onresize = function() {liuxiaofan();};
