JS基础——Cookie与存储

标签：web前端   javascript   cookie   

语法格式：

document.cookie  //name=leo; age=32

六、向Cookie中写入数据
语法格式：

document.cookie = 'username=leo';
document.cookie = 'age=17';

var oDate = new Date();
oDate.setDate(oDate.getDate() + 5);
document.cookie = 'username=leo；expires=' +oDate;

var oDate = new Date();
oDate.setDate(oDate.getDate() + 5);
document.cookie = 'username=leo；expires=' +oDate.toGMTString();

var oDate = new Date();
oDate.setDate(oDate.getDate() + 5);
document.cookie = 'username='+encodeURI('你好吗')+'；expires=' +oDate.toGMTString();
alert(decodeURI(document.cookie));

//读取Cookie的方法
function getCookie(key){
        var arr1 = document.cookie.split('; ');
        for(var i=0;i<arr1.length;i++){
                var arr2 = arr1[i].split('=');
                if(arr2[0] == key){
                        return decodeURI(arr2[1]);
                }
        }
}

function setCookie(key,value,t){
        var oDate = new Date();
        oDate.setDate(oDate.getDate() + t);
        document.cookie = key + '=' + encodeURI(value) + ';expire=' + oDate.toGMTString();
}
