本文实例为大家分享了js实现分页效果的具体代码,供大家参考,具体内容如下
效果如下:
代码:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> <style type="text/css"> </style> </head> <body> <div id="page-nation"></div> <script src="/UploadFiles/2021-04-02/page.js">page.js
var pageNation; pageNation = (function () { function extend(target, source) { for (var obj in source) { target[obj] = source[obj]; } return target; } function pageNation(options) { var defaultOptions = { el: "body",//分页父容器 page: 1, size: 10, total: 0, styUrl: 'style.css', callback: null, IsShowBtn: {//设置需要显示的按钮 choosePageSize: true,//是否显示下拉选项 IsShowPrevOrNextBtn: true,//否显示上一页下一页按钮 IsShowEnterBtn: true,//是否显示跳转输入 IsShowTotalPage:true,//是否显示总页数 } }; this.options = extend(defaultOptions, options) || {}; this.options.el = document.querySelectorAll(this.options.el)[0]; this.pageT = Math.ceil(this.options.total / this.options.size); this.init(); if (!document.querySelector("#dynamic-style")) { this.pageStyle(); } //this.options.callback(1,self.options.size,self.options.total); } var proto = pageNation.prototype || {}; proto.rander = function (page, size, total) { this.options.page = !!page "ol"); ol.classList.add("page-ol"); let p = !!page "li"); li.innerText = i; if (i == p) { li.classList.add("hover"); } ol.appendChild(li); } return ol; })(page); }; var sizeNum = function (size) {//重置size return (function () { let select = document.createElement("select");

暂无原生js实现分页效果的评论...
稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
