我正在尝试为网站编写注册表单并使用此处列出的模板：http://codepen.io/atakan/pen/gqbIz

因此我的HTML文件中的部分看起来像

<!-- multistep form -->
<form id="msform">
  <!-- progressbar -->
  <ul id="progressbar">
    <li class="active">Account Setup</li>
    <li>Social Profiles</li>
    <li>Personal Details</li>
  </ul>
  <!-- fieldsets -->
  <fieldset>
    <h2 class="fs-title">Create your account</h2>
    <h3 class="fs-subtitle">This is step 1</h3>
    <input type="text" name="email" placeholder="Email" />
    <input type="password" name="pass" placeholder="Password" />
    <input type="password" name="cpass" placeholder="Confirm Password" />
    <input type="button" name="next" class="next action-button" value="Next" />
  </fieldset>
  <fieldset>
    <h2 class="fs-title">Social Profiles</h2>
    <h3 class="fs-subtitle">Your presence on the social network</h3>
    <input type="text" name="twitter" placeholder="Twitter" />
    <input type="text" name="facebook" placeholder="Facebook" />
    <input type="text" name="gplus" placeholder="Google Plus" />
    <input type="button" name="previous" class="previous action-button" value="Previous" />
    <input type="button" name="next" class="next action-button" value="Next" />
  </fieldset>
  <fieldset>
    <h2 class="fs-title">Personal Details</h2>
    <h3 class="fs-subtitle">We will never sell it</h3>
    <input type="text" name="fname" placeholder="First Name" />
    <input type="text" name="lname" placeholder="Last Name" />
    <input type="text" name="phone" placeholder="Phone" />
    <textarea name="address" placeholder="Address"></textarea>
    <input type="button" name="previous" class="previous action-button" value="Previous" />
    <input type="submit" name="submit" class="submit action-button" value="Submit" />
  </fieldset>
</form>

JavaScript：

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(){
    if(animating) return false;

    current_fs = $(this).parent();
    next_fs = $(this).parent().next();

            //1. scale current_fs down to 80%
            scale = 1 - (1 - now) * 0.2;
            //2. bring next_fs from the right(50%)

$(".submit").click(function(){

当我点击下一个按钮时，绝对没有任何反应。我试图添加打印语句以查看是否可以解决问题，但似乎没有任何区别，我只包括与问题相关的代码，我没有添加HTML和CSS的其他部分。帮助这个问题。任何帮助将不胜感激

更新：

所以我把

$(document).ready(function() {
围绕JS功能，允许下一个按钮工作，但是我收到错误说

m.easing [this.easing]不是函数

而不是转到下一个窗口，它会在前一个

的正下方显示新窗口

更新2：

修复了问题，它与正在运行的JQuery版本有关

您错过了 jquery.easing.js 文件，并且错误。请添加以下脚本，一切正常。
