下拉菜单验证多个按钮W / Alert

标签: javascript jquery html

我正在尝试创建一个收集有关用户信息的表单。表格有5个步骤:

  

第1步:用户信息(姓名,电子邮件,电话,年龄,性别)

     

第2步:是或否问题

     

第3步:是或否问题

     

第4步:是或否问题

     

第5步:是或否问题

该表单允许用户进入下一阶段,或返回上一步。

在允许用户进入下一步之前,用户必须满足要求。如果问题没有得到解答,验证将提醒用户。

如何为下拉菜单添加验证/ w为所有步骤添加警报,允许用户转到下一步并返回上一步。

我的代码:

var current_fs, next_fs, previous_fs; //fieldsets
var left, opacity, scale; //fieldset properties which we will animate
var animating; //flag to prevent quick multi-click glitches

$(".next").click(function(){
    document.getElementById('btnNext').addEventListener('click',
        function(){
            //text inputs
            if(!document.getElementById('fullname').value){
                alert('Full Name is required');
                return false;
            }

            else if(!document.getElementById('email').value){
                alert('Email is required');
                return false;
            }

            else if(!document.getElementById('phone').value){
                alert('Phone Number is required');
                return false;
            }

            else if(!document.getElementById('age').value){
                alert('Age is required');
                return false;
            }

            //radio buttons
            var genderSet = false;
            var genderBtns = document.getElementsByName('gender');
            //console.log(genderBtns);
            for(var i=0, btn; btn=genderBtns[i];++i){
                if(btn.checked){
                    genderSet=true;
                    break;
                }
            }
            if(!genderSet){
                alert('Gender is required');
                return false
            }
