动画形式没有动画,保留在一个地方

问题描述 投票:0回答:1

是的,基本上我有一个动画形式,我从这里得到:https://tympanus.net/codrops/2010/06/07/fancy-sliding-form-with-jquery/

正如您从演示中看到的那样,当您单击某个选项时,它应该滑动到下一组选项。但对我来说,在下面的代码中,当我点击一个选项时,它只是保持静止。

  <div id="wrapper">
                <div id="steps">
                    <form id="formElem" name="formElem" action="" method="post">
                        <fieldset class="step">
                            <legend>Consultation</legend>
                            <p>
                                <input class = "consultation" type="submit" value="General Consultation">

Why is the jQuery not animating the form?

您没有导入jQuery库。

jQuery是一个API,默认情况下不包含在前端项目中,因此您需要将jQuery库包含在以下script元素中。完成后,您的项目现在可以访问jQuery库并可以为表单设置动画。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

您可以了解有关脚本及其属性以及如何使用它们的更多信息here
