  • jquery.cookie插件用法

    用法说明:

    $.cookie(‘the_cookie’);                                           // 读取 cookie
    $.cookie(‘the_cookie’, 'the_value’); // 存储 cookie
    $.cookie(‘the_cookie’, 'the_value’, { expires: 7 }); // 存储一个带7天期限的 cookie
    $.cookie(‘the_cookie’, '', { expires: -1 }); // 删除 cookie

    插件源码:

    jQuery.cookie = function(name, value, options) {
    if (typeof value != 'undefined') { // name and value given, set cookie
    options = options || {};
    if (value === null) {
    value = '';
    options.expires = -1;
    }
    var expires = '';
    if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) {
    var date;
    if (typeof options.expires == 'number') {
    date = new Date();
    date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));
    } else {
    date = options.expires;
    }
    expires = '; expires=' + date.toUTCString(); // use expires attribute, max-age is not supported by IE
    }
    var path = options.path ? '; path=' + options.path : '';
    var domain = options.domain ? '; domain=' + options.domain : '';
    var secure = options.secure ? '; secure' : '';
    document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join('');
    } else { // only name given, get cookie
    var cookieValue = null;
    if (document.cookie && document.cookie != '') {
    var cookies = document.cookie.split(';');
    for (var i = 0; i < cookies.length; i++) {
    var cookie = jQuery.trim(cookies[i]);
    // Does this cookie string begin with the name we want?
    if (cookie.substring(0, name.length + 1) == (name + '=')) {
    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
    break;
    }
    }
    }
    return cookieValue;
    }
    };
