def DoubleSelect(request):
        CZKType=request.POST.get('CZKType')
        czkclass= CZKClass.objects.filter(CZKType=CZKType)
        data = {'list':czkclass}
        for test in czkclass:
            print data
            print test.CZKType
            print test.CZKName
       # return HttpResponse("%s" % simplejson.dumps({"czkList":czk}))
        return  HttpResponse("%s" % simplejson.dumps(uni_str(data, encode)), mimetype = "application/json")

我想看看 return  HttpResponse("%s" % simplejson.dumps(uni_str(data, encode)), mimetype = "application/json") 在没有返回之前前台用 success: function(data){
                alert(data.msg);
                window.location.reload()
            } 也没有返回!

使用firebug调试，另外在后台打印Response的值。
