Django中有没有一种方法可以使单击带有初始文本的表单时该文本消失？

Question

For example, on some sites in the username form box it says something like "username" and then when you click there the "username" disappears so you can type your username.

Thanks.

Answer 1

Yes, you can do this in a form.

Username =forms.CharField(max_length=35,
                          required=True, 
                          widget=forms.TextInput(attrs={'placeholder': 'Username'}))

Check out the Django Docs for more on how to customize HTML from Django Forms.

Answer 2

您需要为此使用html：

<input type="text" placeholder="This text will disappear" />

Answer 3

我认为您正在寻找占位符属性。
