以下是我的代码，前端页面上为什么不显示短信验证码空缺的信息？
前端代码

<script>
//页面加载完自动执行函数
$(function(){
bindClickBtnSms();
bindClickSubmit();
});
//点击提交注册
function bindClickSubmit() {
$('#btnSubmit').click(function(){
$(".error-msg").empty();
//收集数据
//发送到后台
$.ajax({
url:"/register/",
type:"post",

dataType:"json",

location.href=res.data;
}else{
//错误信息
$.each(res.error,function(key,value){
$('#id_'+key).next().text(value[0]);
})
}
}
})
})
}
</script>
</body>
</html>
后端代码
class RegisterForm(BootStrapModelForm):

widget=forms.PasswordInput(),
min_length=8,
max_length=20,
error_messages={
'min_length': "密码长度不能小于8个字段",
'max_length': "密码长度不能大于20个字段",
})
confirm_password = forms.CharField(label="确认密码", widget=forms.PasswordInput())
mobile = forms.CharField(label="手机号",
validators=[RegexValidator(r'^(1[3|4|5|6|7|8|9])\d{9}$', '手机号格式错误'), ])
code = forms.CharField(label="短信验证码")
class Meta:
model = models.Username
fields = ['username', 'email', 'password', 'confirm_password', 'mobile', 'code']
def register(request):
"""注册"""
if request.method == 'GET':
form = RegisterForm()
return render(request, 'register.html', {'form': form})
form = RegisterForm(data=request.POST)
if form.is_valid():
# 验证通过，写入数据库
form.save()
return JsonResponse({'success': True, 'data': '/login/'})
return JsonResponse({'success': False, 'error': form.errors})
