本文实例为大家分享了js实现瀑布流效果的具体代码，供大家参考，具体内容如下前端内容：使用Javascript和四个div，将照片放入四个div中<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
.container {
width: 1000px;
margin: 0 auto;
background-color: lightgray;
}
.item {
width: 24%;
margin-right: 10px;
float: left;
}
.item img{
width: 100%;
}
</style>
</head>
<body>
{#将内容放在container中#}
<div class="container">
{# 将图片内容放入四个item中，形成四个item#}
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
</div>
<script src="/static/js/jquery-2.1.4.min.js"></script>
<script>
$(function () {
{# 网页加载时自动执行#}
var obj = new ScrollImg();
obj.fetchImg();
obj.scrollEvent();
})
{# 定义对象#}
function ScrollImg() {
this.nid = 0;
{# 取照片方法#}
this.fetchImg = function () {
var that = this
$.ajax({
url: '/get_imgs.html',
type: 'GET',
{# 传输数据，已经取了多少照片，后台可以依据，继续取照片#}
data: {'nid': that.nid},
dataType: 'JSON',
success: function (args) {
if (args.status) {
var img_list = args.data;
$.each(img_list, function (index, obj) {
var eqv = that.nid % 4;
var tag = document.createElement('img')
tag.src = '/' + obj.img_dir;
console.log(eqv)
$('.container').children().eq(eqv).append(tag)
that.nid += 1;
})
}
}
})
}
{# 监听滚动条，当滚到底部时，自动加载数据#}
this.scrollEvent = function () {
var that = this;
$(window).scroll(function () {
var srollTop = $(window).scrollTop();
var winHeight = $(window).height();
var docHeight = $(document).height();
if (srollTop + winHeight >= docHeight - 2) {
that.fetchImg();
}
})
}
}
</script>
</body>
</html>后台内容：基于Django的FBV，函数视图，进行数据的读取和处理ajax请求def get_imgs(request):# 获取已经取得的照片数目index = request.GET.get('nid')#获取QuerySet集合对象，取从index后的10调数据imgs_list = models.Student.objects.values('id','img_dir','name')[index:index+10]
imgs_list = list(imgs_list)
