js 格式验证大全

1.身份证号码验证：

var Common = {
//身份证号验证
    IsIdCardNo: function (IdCard) {
        var reg = /^\d{15}(\d{2}[0-9X])?$/i;
        if (!reg.test(IdCard)) {
            return false;
        }

        if (IdCard.length == 15) {
            var n = new Date();
            var y = n.getFullYear();
            if (parseInt("19" + IdCard.substr(6, 2)) < 1900 || parseInt("19" + IdCard.substr(6, 2)) > y) {
                return false;
            }

            var birth = "19" + IdCard.substr(6, 2) + "-" + IdCard.substr(8, 2) + "-" + IdCard.substr(10, 2);
            if (!Common.IsDate(birth)) {
                return false;
            }
        }
        if (IdCard.length == 18) {
            var n = new Date();
            var y = n.getFullYear();
            if (parseInt(IdCard.substr(6, 4)) < 1900 || parseInt(IdCard.substr(6, 4)) > y) {
                return false;
            }

            var birth = IdCard.substr(6, 4) + "-" + IdCard.substr(10, 2) + "-" + IdCard.substr(12, 2);
            if (!Common.IsDate(birth)) {
                return false;
            }

            iW = new Array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2, 1);

            iSum = 0;
            for (i = 0; i < 17; i++) {
                iC = IdCard.charAt(i);
                iVal = parseInt(iC);
                iSum += iVal * iW[i];
            }

            iJYM = iSum % 11;
            if (iJYM == 0) sJYM = "1";
            else if (iJYM == 1) sJYM = "0";
            else if (iJYM == 2) sJYM = "x";
            else if (iJYM == 3) sJYM = "9";
            else if (iJYM == 4) sJYM = "8";
            else if (iJYM == 5) sJYM = "7";
            else if (iJYM == 6) sJYM = "6";
            else if (iJYM == 7) sJYM = "5";
            else if (iJYM == 8) sJYM = "4";
            else if (iJYM == 9) sJYM = "3";
            else if (iJYM == 10) sJYM = "2";

            var cCheck = IdCard.charAt(17).toLowerCase();
            if (cCheck != sJYM) {
                return false;
            }
        }
        return true;
    },

    //日期验证
    IsDate: function (strDate) {
        var strSeparator = "-"; //日期分隔符
        var strDateArray;
        var intYear;
        var intMonth;
        var intDay;
        var boolLeapYear;
        strDateArray = strDate.split(strSeparator);
        if (strDateArray.length != 3) return false;
        intYear = parseInt(strDateArray[0], 10);
        intMonth = parseInt(strDateArray[1], 10);
        intDay = parseInt(strDateArray[2], 10);
        if (isNaN(intYear) || isNaN(intMonth) || isNaN(intDay)) return false;
        if (intMonth > 12 || intMonth < 1) return false;
        if ((intMonth == 1 || intMonth == 3 || intMonth == 5 || intMonth == 7 || intMonth == 8 || intMonth == 10 || intMonth == 12) && (intDay > 31 || intDay < 1)) return false;
        if ((intMonth == 4 || intMonth == 6 || intMonth == 9 || intMonth == 11) && (intDay > 30 || intDay < 1)) return false;
        if (intMonth == 2) {
            if (intDay < 1) return false;
            boolLeapYear = false;
            if ((intYear % 100) == 0) {
                if ((intYear % 400) == 0) boolLeapYear = true;
            }
            else {
                if ((intYear % 4) == 0) boolLeapYear = true;
            }
            if (boolLeapYear) {
                if (intDay > 29) return false;
            }
            else {
                if (intDay > 28) return false;
            }
        }
        return true;
    }
};

2.QQ号码

Common.Valid = {
    //验证qq号码
    QQNum: function (str) {
        var reg = /^\s*\d{4,12}\s*$/g;
        return reg.test(str);
    },
//空或有效格式验证器
    EmptyOrValid: function (validFunc) {
        var func = validFunc;
        if ($.type(validFunc) == "string")
            func = this[$.trim(validFunc)];
        return function (str) {
            return $.trim(str) === "" || func(str);
        }
    }
};

3.手机号码、电话号码、传真验证：

$(function () {
        String.prototype.isMobile = function () {
            return (/^(?:13\d|15[012356789]|18[0256789]|147)-?\d{5}(\d{3}|\*{3})$/.test($.trim(this)));
        }

        String.prototype.isTel = function () {
            //"兼容格式: 国家代码(2到3位)-区号(2到3位)-电话号码(7到8位)-分机号(1-4位)"
            return (/^(([0\+]\d{2,3}-)?(0\d{2,3}\-)?([2-9]\d{6,7})+(\-\d{1,4})?$/.test($.trim(this)));
        }
        String.prototype.isTelMobile = function () {
            //"兼容格式: 国家代码(2到3位)-区号(2到3位)-电话号码(7到8位)-分机号(1-4位)"
            return (/^(([0\+]\d{2,3}-)?(0\d{2,3}\-)?([2-9]\d{6,7})+(\-\d{1,4})?|(?:13\d|15[012356789]|18[0256789]|147)-?\d{5}(\d{3}|\*{3}))?$/.test($.trim(this)));
        }
});

使用示例如下：

if ($.trim($("#Phone").val()) != "" || $.trim($("#Fax").val()) != "") {
            if (!$.trim($("#Phone").val()).isTel()) {
                Common.ShowInfo("请输入正确的电话号码!");
                return;
            }
            if (!$.trim($("#Fax").val()).isTel()) {
                Common.ShowInfo("请输入正确的传真号!");
                return;
            }
        }
        if ($.trim($("#MobilePhone").val()) != "") {
            if (!$.trim($("#MobilePhone").val()).isMobile()) {
                Common.ShowInfo("请输入正确的手机号码！");
                return;
            }
        }
 $(function () {

});

密码验证（不能包含空格）

String.prototype.hasSpace = function () {
        return (/(^\s+)|(\s+$)|(^\S*\s*\S$)/.test($.trim(this)));
    };

  if($("#Password").val().hasSpace()){//判断
　　　　//
  }
