说到正常的POST,GET方法,我通常都知道自己的方式.

但是,在我的代码中实现ajax-jQuery以进行表单验证是我学习的重要一步.

我有一个包含3个字段的表单：
电子邮件,确认电子邮件和密码.

我正在使用此表单注册新用户.

form.py

class UserField(forms.EmailField):
    def clean(self,value):
        super(UserField,self).clean(value)
        try:
            User.objects.get(username=value)
            raise forms.ValidationError("email already taken.")
        except User.DoesNotExist:
            return value

class RegistrationForm(forms.Form):

    email = UserField(max_length=30,required = True)
    conf_email = UserField(label="Confirm Email",max_length=30,required = True)
    password = forms.CharField(label="Enter New Password",widget=forms.PasswordInput(),required=True)

    def clean(self):
        if 'email' in self.cleaned_data and 'conf_email' in self.cleaned_data:
            if self.cleaned_data['email'] != self.cleaned_data['conf_email']:
                self._errors['email'] = [u'']
                self._errors['conf_email'] = [u'Email must match.']
        return self.cleaned_data
