1、设置cookie

export const setCookie = (key, value, expire) => {
    const d = new Date();
    d.setDate(d.getDate() + expire);
    document.cookie = `${key}=${value};expires=${d.toUTCString()}`
};

2、读取cookie

export const getCookie = (key) => {
    const cookieStr = unescape(document.cookie);
       const arr = cookieStr.split('; ');
       let cookieValue = '';
       for (let i = 0; i < arr.length; i++) {
           const temp = arr[i].split('=');
           if (temp[0] === key) {
               cookieValue = temp[1];
               break
       }
    }
    return cookieValue
};

3、删除cookie

export const delCookie = (key) => {
    document.cookie = `${encodeURIComponent(key)}=;expires=${new Date()}`
};

4、校验身份证号码

export const checkCardNo = (value) => {
    let reg = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/;
    return reg.test(value);
};

5、校验是否包含中文

export const haveCNChars => (value) => {
    return /[\u4e00-\u9fa5]/.test(value);
}

6、校验是否为中国大陆的邮政编码

export const isPostCode = (value) => {
    return /^[1-9][0-9]{5}$/.test(value.toString());
}

7、校验是否为IPv6地址

export const isIPv6 = (str) => {
    return Boolean(str.match(/:/g)?str.match(/:/g).length<=7:false && /::/.test(str)?/^([\da-f]{1,4}(:|::)){1,6}[\da-f]{1,4}$/i.test(str):/^([\da-f]{1,4}:){7}[\da-f]{1,4}$/i.test(str));
}

8、校验是否为邮箱地址

export const isEmail = (value) {
    return /^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+)+$/.test(value);
}

9、校验是否为中国大陆手机号

export const isTel = (value) => {
    return /^1[3,4,5,6,7,8,9][0-9]{9}$/.test(value.toString());
}

10、校验是否包含emoji表情

export const isEmojiCharacter = (value) => {
  	value = String(value);
    for (let i = 0; i < value.length; i++) {
        const hs = value.charCodeAt(i);
        if (0xd800 <= hs && hs <= 0xdbff) {
            if (value.length > 1) {
                const ls = value.charCodeAt(i + 1);
                const uc = ((hs - 0xd800) * 0x400) + (ls - 0xdc00) + 0x10000;
                if (0x1d000 <= uc && uc <= 0x1f77f) {
                    return true;
                }
            }
        } else if (value.length > 1) {
            const ls = value.charCodeAt(i + 1);
            if (ls == 0x20e3) {
                return true;
            }
        } else {
            if (0x2100 <= hs && hs <= 0x27ff) {
                return true;
            } else if (0x2B05 <= hs && hs <= 0x2b07) {
                return true;
            } else if (0x2934 <= hs && hs <= 0x2935) {
                return true;
            } else if (0x3297 <= hs && hs <= 0x3299) {
                return true;
            } else if (hs == 0xa9 || hs == 0xae || hs == 0x303d || hs == 0x3030
                    || hs == 0x2b55 || hs == 0x2b1c || hs == 0x2b1b
                    || hs == 0x2b50) {
                return true;
            }
        }
    }
  	return false;
}
