使用javaScript 取cookie时需要注意的

Posted 2020-10-21 Lucky、Dog

function getCookie(name) {
    var cookies = window.top.document.cookie.split(‘; ‘);//分号后面有个空格
    for (var i = 0; i < cookies.length; i++) {
        var arr2 = cookies[i].split(‘=‘);
        alert(name == arr2[0]);
        alert(arr2);
        if (arr2[0] == name) {
            return arr2[1];
        }
    }
    return ‘‘;
}

分号后面有个空格！！！！！！！！
