html - 如何更改默认 "please include an @ in the email address"？

Question

我已经能够在用户尚未输入电子邮件时更改错误消息，但是当用户输入错误格式的电子邮件时如何更改错误消息？

这是我用 Bootstrap 4 风格编写的代码:

<div class="form-group">
    <label>Email</label>
    <input type="email" name="email" required="" class="form-control" oninvalid="this.setCustomValidity('Please Enter valid email')" oninput="setCustomValidity('')">
</div>

你可以简单地通过在输入标签中添加标题来解决这个问题

<input type="email" class="form-control" name="email" id="freeform_email"
                        placeholder="Enter an email" required="required"
                        oninvalid="this.setCustomValidity('Enter an email that contains &quot@&quot. Example: info@roshni.nl')" title="Email: the email contains '@'. Example: info@ros-bv.nl" />
                    

那么你的应该是:

<div class="form-group">
    <label>Email</label>
    <input type="email" name="email" required="" class="form-control" oninvalid="this.setCustomValidity('Please Enter valid email')"  oninput="this.setCustomValidity('')" title='<your text>'">
</div>

不客气。
