直接代码显示:

view.py文件代码

from django.http import JsonResponse #django ajax部分

def ajax_kchart(request):  
    times = request.POST['shijian']
    chnl = request.POST['chnl']
    chnl_data = keywork_chart(chnl,times)
    data_list = []
    for j in chnl_data:
        data_list.append(j)
    return JsonResponse(data_list,safe=False)

这里关键关注两点 ajax_kchart函数名 和
JsonResponse(data_list,safe=False)返回json的函数

ajax_kchart函数名需要出现在url配置中,Django 1.7
及然后的本子才足以用到JsonResponse,若返回参数是列表,要令safe=False

url.py代码:

url(r'^workchart/$', 'keywork.views.ajax_kchart', name='ajax_kchart'),
