Question

我已经在wordpress中制作了自定义联系表单，用户必须逐步填写输入内容。

我为每一步设置了fieldets，但是需要一些输入，我想检查输入值是否为空，然后让它停止。我自己尝试了一些警告，但无论是空的还是填空它都给了我警报，然后在警报点击“确定”之后它仍然会进入下一步而我不会想要那个。

我希望有人可以帮我解决这个问题。

编辑：我之前已经添加了我尝试过的jQuery。

HTML：

<div class="msform">

    <!-- progressbar -->
    <ul class="progressbar-form">
        <li class="active">Name &amp; Company Name</li>

        <li>Amount &amp; Date</li>
        <li>Subject</li>

为了防止这篇文章再次出现，我已经遗漏了CSS。

Here's a fiddle even tho it doesnt work because its wordpress stuff

Answer 1

StackOverflow相对较新，但如果我理解你的问题，你可以使用以下内容：

if($('.input1').val()){
Your Code here
}

这基本上检查input1是否包含内容，无论是复选框还是文本。

这可能是你正在寻找的东西，也许不是，但嘿，值得帮助：P

希望这有帮助！

Answer 2

它检查所需的类所有输入，也指该字段集之外的输入。所以给了fieldset一个类，让它检查。然后检查后将该类提供给下一个字段集。

显而易见，但我已经失明了。
