直接代码展示:
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)
这里重点关注两点 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 及以后的版本才可以用到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‘),
