这几天想提高一下python的水准，本来想弄个24点运算，在网页上输出结果的，结果整着整着，就转移到了Django+jQuery上面来了。
最后，兴趣转移到了django如何使用AJAX框架上。google了一些网页，好像还很复杂的样子，偶记得当时玩PHP时好像没有那么复杂啊？学着网页上的例子来了一遍，感觉还是太麻烦。然而，当google AJAX框架的时候，居然发现jQuery是直接支持AJAX的，那么，还使用其它的plugins支持AJAX肯定是走入了歧路。鼓捣了一阵，终于找到了办法，留贴为记:

呵呵，用jQuery简单清晰多了
mysite的urls.py
(r'^ajax/', include('ajax_jq.urls')),
app的urls.py:
(r'^index/', views.index),
(r'^getdata/', views.getdata),
views.py:
def index(request):
ggg="hhhhhhhhh"
return render_to_response("index.html",locals())
FIB = [0,1]
def get_fib_sequence():
global FIB
FIB.append(FIB[-1] + FIB[-2])
return FIB
def getdata(request):
gg="2000-9-9"
if request.GET:
gg="nihao a "
if request.REQUEST.has_key("ts"):
gg = request.REQUEST["ts"]
global FIB
get_fib_sequence()
ss = " --- Fibonacii number: %d,%d" % (FIB[0], FIB[1])
gg+= ss
return HttpResponse(gg)
打开Chrome，输入127.0.0.1:8000/ajax/getdata，工作OK
