个人学习记录1：二维数组保存到cookie后再读取

二维数组保存到cookie后再读取

var heartsArray = [[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],[0,0,0,0,0,0,0,0,0,0,0],[0,0,0,0,0,0,0,0,0,0],[0,0,0,0,0,0,0,0,0,0,0]];

//将二维数组编码
var hearts = escape(JSON.stringify(heartsArray));
//保存到cookie
setHeartsToCookie(hearts);

setTimeout(function() {
    //从cookie中获取
    var val = getHeartsFromCookie("HeartsCookie");
    //解码为数组的字符串
    var newStr = unescape(unescape(val));
    //将字符串转为二维数组
    var newArray = eval(newStr);
},1000);

function setHeartsToCookie(hearts) {
    setCookie("HeartsCookie",hearts,"d1");
}
function getHeartsFromCookie(cookieName) {
    return getCookie(cookieName);
}
