html5本地存储实现游戏历史记录
//获取游戏历史记录
function gameHistory(){
//读取 localStage 本地存储中的浏览记录
if (window.localStorage.games){
var jsonStr = window.localStorage.games;
if(jsonStr.length<=0 || jsonStr=="" || jsonStr == null){
$("#recent_title").hide();
$("#recent").hide();
}else{
var data = JSON.parse("["+jsonStr+"]");
var len = data.length;
if (len > 0){
for(var i=0; i< len; i++){
$("#recent").append('<a style="width:20%;" href="toGameRanking.do?id='+data[i].GAME_ID+'"><img src="'+data[i].GAME_LOGO+'" /><br />'+data[i].GAME_NAME+'</a>');
if (i==4){
break;
}
}
}else{
$("#recent_title").hide();
$("#recent").hide();
}
}
}else{
$("#recent_title").hide();
$("#recent").hide();
}
}
//设置游戏浏览记录到HTML5本地存储
function setHistory(gameId,game){
//格式为：game = '{"GAME_ID":"1","GAME_NAME":"2048","GAME_LOGO":"img/e168eff1-4c90-489a-aaa9-3d9eea8350e9.png"}';
if(game.length>0){
if (window.localStorage.games){
if (window.localStorage.games.indexOf(gameId)<0){
if(window.localStorage.games.length<=0){
window.localStorage.games = game;
}else{
window.localStorage.games = game+","+window.localStorage.games;
}
}
}else{
window.localStorage.games=game;
}
}
}
