ajax高級操做

$('#ajax_submit').click(function () {
            $.ajax({
                'url':'/app_ajax',
                'type':'post',
                'data':$("#f1").serialize(),      #將一個form表單所有發送到後臺
{#                'data':{'app_name':'123','host_lists':[1,2,3,4]},#}
                traditional:true,    #支持能發送數組格式到後臺 
                dataType:'JSON',      #不用將後臺返回的json格式解析，省去obj = JSON.parse(data)
                success:function (obj) {
                    if(obj.status=='true'){
                        $('#msg').removeClass('hide').text(obj.data);
{#                        location.reload();#}
                    }else {
                        $('#msg').removeClass('hide').text(obj.error);
                    }
                },
                error:function () {    #只有後臺出的錯誤 沒有被捕獲到，或不識別才執行
                    alert('undifine error');
                }
            })


後臺：

def app_ajax(request):    ret = {"status":"true","data":"none","error":"none"}    try:        name = request.POST.get('app_name')        hosts = request.POST.getlist('host_lists')        if name and hosts:            obj = models.app.objects.create(name=name)            obj.r.add(*hosts)            ret['data']='success'        else:            ret['status']='false'            ret['error']='error'    except Exception as e:        pass    return HttpResponse(json.dumps(ret))
