本文实例讲述了JS表的模拟方法。分享给大家供大家参考。具体方法如下：
<!doctype html><html> <head> <meta charset="utf-8"> <title>列表</title> <script> function List(){ this.listSize= 0; this.pos=0; this.dataStore=[];//初始化一个空数组来保存列表元素 this.clear =clear; this.find = find; this.toString= toString; this.insert = insert; this.append= append; this.remove =remove; this.front = front; this.end = end; this.prev =prev; this.next = next; this.length= length; this.currPos= currPos; this.moveTo= moveTo; this.getElement =getElement; this.length = length; this.contains = contains; function append(element){ this.dataStore[this.listSize++] = element; }; function find(element){ for(var i =0; i<this.dataStore.length; i++){ if(this.dataStore[i]===element){ return i ; } } return -1; } function remove(element){ var foundAt =this.find(element); if(foundAt!=-1){ this.dataStore.splice(foundAt,1); this.listSize--; return element; //return true 原本是这样，后面本人改为ELEMENT }else{ return false; } } function length(){ return this.listSize; } function toString(){ return this.dataStore; } function insert(element,after){ var insertPos = this.find(after); if(insertPos!=-1){ this.dataStore.splice(insertPos+1,0,element); this.listSize++; return true; }else{ return false; } } function clear (){ delete this.dataStore; this.listSize=0; this.pos=0; this.dataStore=[]; } function contains(element){ for(var i =0; i<this.dataStore.length; i++){ if(this.dataStore[i]===element){ return true ; } } return false; } function front(){ this.pos = 0; } function end(){ this.pos = this.listSize-1; } function prev(){ // if(this.pos> 0){ --this.pos; // } } function next(){ // if(this.pos< this.listSize-1){ ++this.pos; // } } function currPos(){ return this.pos; } function moveTo(pos){ this.pos= pos; } function getElement(){ return this.dataStore[this.pos]; } } var list = new List(); list.append({name:'夏广成',sex:'男'}); list.append({name:'江荣盛',sex:'男'}); list.append({name:'杜强',sex:'男'}); list.append({name:'巧华',sex:'女'}); list.append({name:'方阳',sex:'男'}); for(list.front(); list.currPos() < list.length() ; list.next()){ var item = list.getElement(); if(item.sex =='女'){ list.remove(item); } } for(list.front(); list.currPos() < list.length() ; list.next()){ var item = list.getElement(); console.log(item.name); } </script> </head> <body > </body></html>希望本文所述对大家的javascript程序设计有所帮助。
