您好我有以下模板，我想发送一个POST请求来激活ajax以保存多个复选框的选择。当我查看控制台时，它会在用户按下按钮时显示GET请求，为什么会这样？

这是用户选择复选框的个人资料页面的视图。
def profile(request):
owner = User.objects.get (formattedusername=request.user.formattedusername)
reportdetail = QVReportAccess.objects.filter(ntname = owner.formattedusername, active = 1).values('report_name_sc')

reportGroups = QVReportAccess.objects.filter(ntname = owner.formattedusername).values_list('report_group_id', flat=True)
reportlist = QvReportList.objects.filter(~Q(report_id__in= reportIds)).exclude(active=0)
allreportgrouplist = QvReportList.objects.filter(~Q(report_id__in= reportIds)).filter(report_group_id = 100)
bhreportgrouplist = QvReportList.objects.filter(~Q(report_id__in= reportIds)).filter(report_group_id = 200)

pireportgrouplist = QvReportList.objects.filter(~Q(report_id__in= reportIds)).filter(report_group_id = 1100)
screportgrouplist = QvReportList.objects.filter(~Q(report_id__in= reportIds)).filter(report_group_id = 1200)

othreportgrouplist = QvReportList.objects.filter(~Q(report_id__in= reportIds)).filter(report_group_id = 99999)
# if request.method == 'POST':
# reportnamesc = request.POST.get('report_name_sc', '')
# checked = request.POST.get('request_reports', '')
# request_reports = #request_reports.objects.get(report_name_sc=reportnamesc)
# request_reports.request_reports = checked
# request_reports.save()
args = {'user':owner, 'applicationaccess':reportaccess, 'applicationlist':reportlist, 'bhgrouplist':bhreportgrouplist, 'cegrouplist':cereportgrouplist, 'fingrouplist':finreportgrouplist

return render(request, 'accounts/profile.html', args)
但是，由于我的帖子从未发生过，ajax不保存我的值，我可以在我的表单上执行request.POST ['request_reports']，只提取已检查的报告。
如果有更好的方法可以完成从一个html模板到表单的用户选择减少报告的任务，我愿意接受建议。

您不会阻止按钮的默认操作，即提交表单 - 而表单又使用默认操作GET。
点击事件处理程序获取event参数并调用event.preventDefault();。
