问题描述：

我使用此表格

<div class="row">
    <form class="col s12">
        <div class="row">
            <div class="input-field col s12">
                <input id="email2" type="email" class="validate">
                <label for="email2" data-error="wrong" data-success="right">Email</label>
            </div>
            <div class="input-field col s12">
                <input id="example" name="example" type="text" class="validate" required="" aria-required="true">
                <label for="example" data-error="wrong" data-success="right">Field</label>
            </div>
        </div>
    </form>
</div>

邮件字段正常。如果我在不正确的邮件地址中发布错误消息。

mail field is ok. if I post in an incorrect mail address error message appears.

示例字段不起作用。我会检查字段是否为空，然后显示错误。

example field not work. i would check if field is not empty and then show error.

出了什么问题？

答

您忘记添加 required =和 aria-required =true $ b这里的$ b是完整的代码段：

You forgot to add required="" and aria-required="true" here is the completes snippet:

<div class="row">
    <form class="col s12">
        <div class="row">
            <div class="input-field col s12">
                <input id="email2" type="email" class="validate" required="" aria-required="true">
                <label for="email2" data-error="wrong" data-success="right">Email</label>
            </div>
            <div class="input-field col s12">
                <input id="example" name="example" type="text" class="validate" required="" aria-required="true">
                <label for="example" data-error="wrong" data-success="right">Field</label>
            </div>
            <div class="input-field col s12">
                <button class="btn waves-effect waves-light" type="submit" name="action">Submit</button>
            </div>
        </div>
    </form>
</div>
