1、django获取post过来的多个键值对：

Ajax:

var languages = {};
languages['english'] = ['mark', 'james'];
languages['spanish'] = ['amy', 'john'];

$.ajax({
type: 'POST',
url: '/save/',
data: languages,
dataType: 'json'

});

Django Views.py

if request.is_ajax() and request.method == 'POST':
for key in request.POST:
print key
valuelist = request.POST.getlist(key)
print valuelist

---------------------

fiddle：

name=june; age=26;

---------------------

views.py

16 for key in request.POST: 17 print key 18 valuelist = request.POST.getlist(key) 19 print valuelist
----------------------------

Development server is running at http://192.168.1.102:8357/ Quit the server with CONTROL-C. Your method is POST!>>>>>>>>> name [u'june']
age [u'26'] [04/Apr/2012 10:58:11] "POST /getuin/ HTTP/1.1" 200 20

2、一次加载所有值：

def view_example(request):
data=simplejson.loads(request.raw_post_data)
3、获取多个值作为一个列表

request.POST get multiple values

The QueryDict.getlist() allows to get all the checkbox(or select list) values from the request.POST/GET object.
Let’s assume we have a simple form with the following checkboxes. Each checkbox contains an ID of an artist. 1 <form method="post" action=""> 2 ... 3 <input value="1" name="artists" type="checkbox"> 4 <input value="2" name="artists" type="checkbox"> 5 <input value="3" name="artists" type="checkbox"> 6 ... 7 </form>
In views.py : 1 def handle(request): 2 if request.method == 'POST': 3 artists = request.POST.getlist('artists') # now artists is a list of [1,2,3]
