django项目注册页面ajax验证

ajax post方式提交时需要在 data中添加 "csrfmiddlewaretoken":$("[name=csrfmiddlewaretoken]").val()

user/url.py

urlpatterns = [
    url(r"^check_username/$",views.check_username,name="check_username"),
    url(r"^check_password/$",views.check_password,name="check_password"),
    url(r"^check_password2/$",views.check_password2,name="check_password2"),
    url(r"^check_img_code/$",views.check_img_code,name="check_img_code"),
...]

user/register.html

{% load static from staticfiles %}



{% csrf_token %}

    

        
用户名:
        

        

    
    

        
密码:
        

        

    
    

        
确认密码:
        

        

    
    

        
 验证码:
