Django Ajax template

<div>    <input type="text" name="user" id="user"/>    <input type="text" name="pwd" id="pwd" />    <input type="button" id="btn" value="提交"/></div><script>$(function(){    bindBtn();});function bindBtn(){    $('#btn').click(function(){      #这里绑定个点击事件        var u = $('#user').val();        var p = $('#pwd').val();        #dataType:'JSON' 也可以使用这个进行数据的转换        $.ajax({            url:'/aj/',               #提交的url            type:'POST',              #提交的方法            data:{'uuu':u,'ppp':p},            success:function(data){    #等待返回数据的回调函数                var data_dict = JSON.parse(data);   #取字典中的值                if (data_dict.status){                                 location.href = '/home/' }else{                      alert(data_dict.error);                      }            }        })})}</script>

#views.py 的方法def aj(request):    if request.method == "GET":        return render(request,'aj.html')    elif request.method == "POST":        user = request.POST.get('uuu')        pwd = request.POST.get('ppp')        obj=models.UserInfo.objects.\        filter(username=user,password=pwd).\        first()        ret = {'status':True,'error:None'}        if obj:            request.session['user'] = user #存session            request.session['pwd'] = pwd            return HttpResponse(json.dumps(ret))        else:            ret['status'] = False            ret['error'] = "用户名或者密码错误"            return HttpResponse(json.dumps(ret))
