推荐答案

我认为您的问题是您已经在文本框中添加了一个值.意味着里面已经有东西了.它认为它充满了.

I think your problem is that you already add a value inside the textbox. Meaning there is already something in it. It thinks its filled.

如果您清空该字段并单击按钮，则会弹出警告，提示该字段为必填项.

If you empty the field and click the button a warning will pop-up saying that field is required.

从表单中删除value=，然后重试.

Remove the value= from your form and try again.

您还可以在输入字段之前添加文本，如下所示:

You can also add text in front of the input fields like this:

To: <input type="text" id="to" class="cleardefault to" name="to" size="8px" required /><br />具有相同的效果.但必须填写必填字段.

To: <input type="text" id="to" class="cleardefault to" name="to" size="8px" required /><br /> with the same effect. But with working required fields.
