增加相应的请求处理函数:

def getdevjson(request):
print 'get here'
if ('key' in request.GET):
searchkey = request.GET.get('key')
return JsonResponse(search(searchkey))
else:
return HttpResponse('Sorry!')
|
返回字符串中,既可以使用from django.http import JsonResponse,也可以使用HttpResponse(json.dumps(res))

#calculate是一个按钮,点击动作绑定了提交函数submit_form,ajax的请求参数中,data中包含了查询参数,success是请求成功后的动作,注意返回的res需要进行json解析才可以正确使用:root = JSON.parse(jsondata);update(res)是一个更新网页内容的函数
路由配置修改
urls.py中修改如下:

from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
url(r'^getdevjson$','dev.views.getdevjson',name='getdevjson'),
url(r'^','dev.views.index',name='index'),
url(r'^admin/', include(admin.site.urls)),
)
|
需要注意的是为了避免路由被覆盖,将index的路由配置尽量放置在最后一行。
