我试图创建一个带有进度条的表单（逐步）。我这里有这段代码：

我遇到的问题是表单从最后一个fieldset 开始出现，并且没有收集我的信息。什么问题，我该如何解决？

【问题讨论】：

您的表单在加载时显示最后一个fieldset 的原因是，前两个在其样式标签中有display: none; opacity: 0;，而最后一个有display: block; opacity: 1。您将最后一个字段集明确设置为可见字段。你有什么问题？
不收集我的信息....我不明白。请您提一下最后显示fieldset first 的座右铭是什么。
我的意思是它不提交。
@DavidHedlund 这解决了我关于显示的问题。但是我的进度条还是在开头显示3.页。
这里是我的代码链接：PHP TEST SERVER

标签： javascript jquery html css forms

【解决方案1】：

我遇到的问题是表单从最后一个字段集中显示

您的代码明确指定了这一点：

<fieldset style="opacity: 0; transform: scale(0.8); display: none;">
...
<fieldset style="display: none; left: 0%; opacity: 0; transform: scale(0.8);">
...
<fieldset style="display: block; left: 0%; opacity: 1;">

但是我的进度条还是在开头显示3.页面

同样，这是您的标记指定的内容。所有项目都处于活动状态：

<ul id="progressbar">
    <li class="active">Account Setup</li>
    <li class="active">Social Profiles</li>
    <li class="active">Personal Details</li>
</ul>

它没有提交

你的表单提交代码是什么？

$(".submit").click(function(){
    return false;
})

这里没有明确的问题需要回答。一切都完全按照您的代码指示进行。没有明显的错误，至少与您的问题描述不符。你写过这个吗？你了解这段代码吗？如果您希望在提交时发生某些事情，您为此做了什么尝试？

【解决方案2】：

您需要清除进度条类active，并修复fieldset inline css opacity 和display，并且在之前的动画完成时忘记将animating 设置为false。
