js各種驗證總結

1、郵箱驗證

function isEmail(str){
    var reg = /^([a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+((\.[a-zA-Z0-9_-]{2,3}){1,2})$/;
    if(!reg.test(str))
    {
        alert('請輸入有效的郵箱！');
        return false;
    }else{
        return true;
    }
}

2、電話驗證

function validatemobile(mobile)
{
    if(mobile.length==0)
    {
        alert('請輸入手機號碼！');
        return false;
    }
    if(mobile.length!=11)
    {
        alert('請輸入有效的手機號碼！');
        return false;
    }

    var myreg = /^(((13[0-9]{1})|(14[0-9]{1})|(15[0-9]{1})|(17[0-9]{1})|(18[0-9]{1})|(19[0-9]{1}))+\d{8})$/;
    if(!myreg.test(mobile))
    {
        alert('請輸入有效的手機號碼！');
        return false;
    }else{
        return true;
    }
}

3、身份證格式驗證

function checkNumber(id){
    var reg = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/;
    if (reg.test(id) === false) {
        alert("身份證輸入不合法");
        return false;
    }else{
        return true;
    }
}

4、身份證是有有效及格式驗證

function IdentityCodeValid(code) {
    var city={11:"北京",12:"天津",13:"河北",14:"山西",15:"內蒙古",21:"遼寧",22:"吉林",23:"黑龍江 ",31:"上海",32:"江蘇",33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山東",41:"河南",42:"湖北 ",43:"湖南",44:"廣東",45:"廣西",46:"海南",50:"重慶",51:"四川",52:"貴州",53:"雲南",54:"西藏 ",61:"陝西",62:"甘肅",63:"青海",64:"寧夏",65:"新疆",71:"臺灣",81:"香港",82:"澳門",91:"國外 "};
    var tip = "";
    var pass= true;

    if(!code || !/^\d{6}(18|19|20)?\d{2}(0[1-9]|1[12])(0[1-9]|[12]\d|3[01])\d{3}(\d|X)$/i.test(code)){
        tip = "身份證號格式錯誤";
        pass = false;
    }

    else if(!city[code.substr(0,2)]){
        tip = "地址編碼錯誤";
        pass = false;
    }
    else{
        //18位身份證需要驗證最後一位校驗位
        if(code.length == 18){
            code = code.split('');
            //∑(ai×Wi)(mod 11)
            //加權因子
            var factor = [ 7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2 ];
            //校驗位
            var parity = [ 1, 0, 'X', 9, 8, 7, 6, 5, 4, 3, 2 ];
            var sum = 0;
            var ai = 0;
            var wi = 0;
            for (var i = 0; i < 17; i++)
            {
                ai = code[i];
                wi = factor[i];
                sum += ai * wi;
            }
            var last = parity[sum % 11];
            if(parity[sum % 11] != code[17]){
                console.log(last);
                tip = "校驗位錯誤";
                pass =false;
            }
        }
    }
    if(!pass) groy(tip);
    return pass;
}

5、香港身份證格式及是否有效

function IsHKID(str) {
    var strValidChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

    // basic check length
    if (str.length < 8)
        return false;
  
    // handling bracket
    if (str.charAt(str.length-3) == '(' && str.charAt(str.length-1) == ')')
        str = str.substring(0, str.length - 3) + str.charAt(str.length -2);

    // convert to upper case
    str = str.toUpperCase();

    // regular expression to check pattern and split
    var hkidPat = /^([A-Z]{1,2})([0-9]{6})([A0-9])$/;
    var matchArray = str.match(hkidPat);

    // not match, return false
    if (matchArray == null)
        return false;

    // the character part, numeric part and check digit part
    var charPart = matchArray[1];
    var numPart = matchArray[2];
    var checkDigit = matchArray[3];

    // calculate the checksum for character part
    var checkSum = 0;
    if (charPart.length == 2) {
        checkSum += 9 * (10 + strValidChars.indexOf(charPart.charAt(0)));
        checkSum += 8 * (10 + strValidChars.indexOf(charPart.charAt(1)));
    } else {
        checkSum += 9 * 36;
        checkSum += 8 * (10 + strValidChars.indexOf(charPart));
    }

    // calculate the checksum for numeric part
    for (var i = 0, j = 7; i < numPart.length; i++, j--)
        checkSum += j * numPart.charAt(i);

    // verify the check digit
    var remaining = checkSum % 11;
    var verify = remaining == 0 ? 0 : 11 - remaining;

    return verify == checkDigit || (verify == 10 && checkDigit == 'A');
} 

6、香港身份證格式

function IsHKID(str) {
    var strValidChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

    // basic check length
    if (str.length < 8)
        return false;
  
    // handling bracket
    if (str.charAt(str.length-3) == '(' && str.charAt(str.length-1) == ')')
        str = str.substring(0, str.length - 3) + str.charAt(str.length -2);

    // convert to upper case
    str = str.toUpperCase();

    // regular expression to check pattern and split
    var hkidPat = /^([A-Z]{1,2})([0-9]{6})([A0-9])$/;
    var matchArray = str.match(hkidPat);

    // not match, return false
    if (matchArray == null)
        return false;
    return true;
 }
