Exemple de code utilisant du javascript natif pour obtenir un effet de pagination

function pageFunc(conf){
 this.myFunc = conf.click //用户点击要执行的方法
 this.total = conf.total; //总页数
 this.currentPage = 1; //当前页码
 this.init()  //初始化 
}

pageFunc.prototype.init = function(){
 var total = this.total,
 currentPage = this.currentPage,
 _this = this;

 listeners = {
 'setWhat' : function(opts) {
  _this.aClick(opts.src)
  return false;
 }
 };

 listenersPre = {
 'lmw-pre' : function(opts) {
  _this.prevClick()
  return false;
 }
 };

 listenersAdd = {
 'lmw-add' : function(opts) {
  _this.addClick()
  return false;
 }
 };

 var rootele = this.createPage(1,total);
 document.getElementById('page-coat').innerHTML = rootele

 $on(document.getElementById('page-coat'), ['click'], listeners);//点击a标签
 $on(document.getElementById('page-coat'), ['click'], listenersPre);//点击上一页
 $on(document.getElementById('page-coat'), ['click'], listenersAdd);//点击下一页

}
//创建HTML分页结构字符串
pageFunc.prototype.createPage = function(page,total){
 var str = `<a class="lmw-current" href="#" rel="external nofollow" rel="external nofollow"

//二：封装事件代理方法

 src : src,
 e : e,
 action : action
 });

 if (returnVal === false) {
 break;
 }

 src = src.parentNode;
 }
 });
};
//1、封装跨浏览器事件绑定方法
function $addEvent(obj, type, handle) {

 return;
 }

 if( type instanceof Array) {
 for(var i = 0, l = type.length; i < l; i++) {

//2、解决IE中this指向window的问题
 function createDelegate(handle, context) {
 return function() {
 return handle.apply(context, arguments);
