ajax的格式、简单使用编写,

url

from django.conf.urls import url
from django.contrib import admin
from app.views import classes
from app.views import student
from app.views import ajax
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^classes.html$',classes.get_classes),#不加^访问点击页面没反应
    url(r'^add_classes.html$',classes.add_classes),
    url(r'^del_classes.html$', classes.del_classes),
    url(r'^edit_classes.html$',classes.edit_classes),
    url(r'^set_teacher.html$', classes.set_teacher),

    url(r'^student$', student.get_student),
    url(r'^add_student$', student.add_student),
    url(r'^del_student$', student.del_student),
    url(r'^edit_student$',student.edit_student),
    url(r'^ajax1$', ajax.ajax1),
    url(r'^ajax2$', ajax.ajax2),
    url(r'^ajax3$', ajax.ajax3),

]

ajax.py

from django.shortcuts import render,HttpResponse

def ajax1(req):
    return render(req,'ajax1.html')

def ajax2(req):
    user=req.GET.get('username')
    pwd=req.GET.get('password')
    import time
    time.sleep(5)
    return HttpResponse('你好')
def ajax3(req):
    v1=req.POST.get('a1')
    v2=req.POST.get('a2')
    try:
        v3=int(v1)+int(v2)
    except Exception as e:
            v3='格式错误'
    return HttpResponse(v3)
