...And what's the problem you're having? Any information from your Javascript console? Maybe you haven't set up your django app to use CSRF protection.

......你遇到的问题是什么？您的Javascript控制台中的任何信息？也许你没有设置你的django应用程序来使用CSRF保护。

Finally I got a 'hello' from the server!

最后我从服务器得到了一个'你好'！

urls.py:
from django.views.generic.simple import direct_to_template

(r'^hello/$',direct_to_template, {'template': 'jqueryserver.html'}),
(r'^jqueryserver/$',views.jqueryserver),

views.py:

views.py：

#other imports
from django.views.decorators.csrf import csrf_exempt
from django.core.context_processors import csrf
from django.views.decorators.csrf import csrf_protect

def jqueryserver(request):
    print "in jqueryserver"
    response_string="hello"
    if request.method == 'GET':
        if request.is_ajax()== True:
            return HttpResponse(response_string,mimetype='text/plain')

jqueryserver.html
