前端常用正则校验

校验邮箱方法

function validEmail(v){
    var result = false;
    var a = v.indexOf('-')>0?v.replace(/-/g,''):v;
    var len = a.length;
    if(len == 0)return true;
    if(v != undefined && v != "" && v != null){  //在此校验
        var  reg = /^([a-zA-Z0-9]+[_|\_|\.]?)*[a-zA-Z0-9]+@([a-zA-Z0-9]+[_|\_|\.]?)*[a-zA-Z0-9]+\.[a-zA-Z]{2,3}$/;
        result =  reg.test(a);
    }
    return result;
}

校验电话

    function validWPhone(v){
        var result = false;
        var len = v.length;
        if(len == 0) return true;
        if(v != undefined && v != "" && v != null){
            var isPhone = /^([0-9]{3,4}-)?[0-9]{7,8}$/;
            var isMob=/^[1][0-9]{10}$/;
            if(isMob.test(v)||isPhone.test(v)){
                result = true;
            }
            else{
                result = false;
            }
        }
        return result;
    }

校验手机号

    function validCustomerPhone(v){
        var result = false;
        var a = v.indexOf('-')>0?v.replace(/-/g,''):v;
        var len = a.length;
        if(len == 0) return true;
        if(v != undefined && v != "" && v != null){
            var  reg =  /^[1][0-9]{10}$/;
            result =  reg.test(a);
        }
        return result;
    }
