如何使用javascript删除django定义的属性？

我试图使密码字段仅在选中复选框时为必填字段。最初选中该复选框，以便在Django中定义必填字段：

forms.py
class SampleForm(forms.ModelForm):
    check_box = forms.BooleanField(required=False)
    password1 = forms.CharField(widget=forms.PasswordInput)
    password2 = forms.CharField(widget=forms.PasswordInput)
    class Meta:
        model=MyModel
    def __init__(self, *args, **kwargs):
        super(SampleForm,self).__init__(*args, **kwargs)
        self.fields['check_box'].widget.attrs.update({'onclick':"hidePass()",'id':"check"}) 
        self.fields['password1'].widget.attrs.update({'id':"password1"})
        self.fields['password2'].widget.attrs.update({'id':"password2"}) 

我尝试了以下方法：

<script>
function hidePass() {
  var checkBox = document.getElementById("check");
  var password1 = document.getElementById("password1");
  var password2 = document.getElementById("password2");
  
  if (checkBox.checked == true){
    password1.disabled = false;
    password1.required = true;
    password2.disabled = false;
    password2.required = true;
        
  } else {
    password1.disabled = true;
    password1.required = false;
    password2.disabled = true;
    password2.required = false;
  }
}
</script>

但是我得到了同样的结果

password1.required = false;

password1.removeAttribute("required");
