实现最佳实践验证空白字段

Question

我用这个表格

<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post在一个不正确的邮件地址出现错误消息。

示例字段无效。我会检查字段是否不为空然后显示错误。

怎么了？

您忘记添加 required="" 和 aria-required="true" 这是完整的片段：

<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>

/** 修复错误消息 */

label {
    width: 100%;
}
.input-field label:not(.active):after {
    font-size: 0.8rem;
    -webkit-transform: translateY(-140%);
    -moz-transform: translateY(-140%);
