前端常用正则验证

1、非空验证

function cPhoneModlue() {
        var valphone = $.trim($('.phone_Module').val());
        if(valphone == ""){
            $('.phone_Module').parents(".mandatory").addClass("warning");
            truePhoneModule = false;
        }else{
            $('.phone_Module').parents(".mandatory").removeClass("warning");
            truePhoneModule = true;
        };
    };

2、手机号码验证

function cPhone() {
        var val = $.trim($('.phone').val());
        var phoneReg = /^1[34578]\d{9}$/;
        if (!phoneReg.test(val)) {
            $('.phone').parents(".mandatory").addClass("warning");
            truePhone = false;
        } else {
            $('.phone').parents(".mandatory").removeClass("warning");
            truePhone = true;
        };
        
    };

3、身份证验证

//身份证验证
    function IdentityCodeValid() { 
        var code = $.trim($('.code').val());
        var city={11:"北京",12:"天津",13:"河北",14:"山西",15:"内蒙古",21:"辽宁",22:"吉林",23:"黑龙江 ",31:"上海",32:"江苏",33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山东",41:"河南",42:"湖北 ",43:"湖南",44:"广东",45:"广西",46:"海南",50:"重庆",51:"四川",52:"贵州",53:"云南",54:"西藏 ",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"新疆",71:"台湾",81:"香港",82:"澳门",91:"国外 "};
        var tip = "";
        
        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) || code == ""){
            $('.code').parents(".mandatory").addClass("warning");
            trueCode = false;
            /*tip = "身份证号格式错误";*/
        }else if(!city[code.substr(0,2)]){
            //tip = "地址编码错误";
            $('.code').parents(".mandatory").addClass("warning");
            trueCode = false;
        }else{
            //18位身份证需要验证最后一位校验位
            if(code.length == 18){
                code = code.split('');
                //∑(ai×Wi)(mod 11)
                //加权因子
                var factor = [ 7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2 ];
                //校验位
                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]){
                    //tip = "校验位错误";
                     $('.code').parents(".mandatory").removeClass("warning");
                    trueCode = true;
                }
            }
        }
    };

4、6-15位数字与字母组合

function passwordRed(a) {
        var passwordReg = /^(?![^a-zA-Z]+$)(?!\D+$).{6,15}$/;
        var val = $(a).val();
        if (!passwordReg.test(val)) {
            //错误
        } else {
            //正确
        }
    }

5、验证第二次输入的密码

function passwordRepeat(a) {
        var name = $(a);
        if ($("#pwd_1").val() != $("#pwd_1_2").val() || name.val() == '') {
        //错误
        } else {
       //正确
        }
    }
