django将占位符文本添加到表单字段

您必须使用占位符属性

class LoginForm(forms.Form):    username = forms.CharField(label='username')    password = forms.CharField(label='password')    def __init__(self, *args, **kwargs):        super(LoginForm, self).__init__(*args, **kwargs)        self.fields['username'].widget.attrs['placeholder'] = 'username'        self.fields['password '].widget.attrs['placeholder'] = 'password'

要么

class LoginForm(forms.Form):    username = forms.CharField(label='username',widget=forms.TextInput(attrs={'placeholder':'username'}))    password = forms.CharField(label='password',widget=forms.PasswordInput(attrs={'placeholder':'password'}))
