django通过ajax发起请求返回JSON格式的数据，djangojson,这是python,dja

这是python,django handler代码：

def checkemail(request):    user = None    if request.POST.has_key('email'):        useremail = request.POST['email']        result = {}        user = User.objects.filter(useremail__iexact = useremail)    if user:        result = "1"        result = simplejson.dumps(result)    else:        result = "0"        result = simplejson.dumps(result)    return HttpResponse(result, mimetype='application/javascript')

这是AJAX部分

if(valid_email($('#reg-for-email').val())){            var email = $('#reg-for-email').val();            //这里把用户输入的EMAIL地址提交到后台数据库中去验证是否已存在。            $.ajax({               type:"POST" ,               url:"/reg/checkemail",               data:"email=" + email ,               cache: false,               success: function(result){                   if (result==1)                     {                       $("#reg-for-email-msg").removeClass("g-hide");                       $('#reg-for-email-msg').removeClass("msg-isok").addClass("msg-error").html("该邮箱已存在！");                       eok = true;                     }                     else                     {                       $("#reg-for-email-msg").addClass("g-hide");                       eok = false;                     }               }             })        }

URL的配置是:

url(r'^reg/checkemail/', 'reg.views.checkemail', name='ce'),
