Question

我正在创建反馈应用，在结果部分，我需要为每个问题显示Google Charts。列是静态的是和没有，但是数据需要动态设置，所以我使用window.load来显示页面。显示数据的格式是

Question
chart

有更好的方法吗？

views.py

@expose('/_charts',methods=["GET","POST"])
def load_chart(self):
    stream_id=request.args.get('stream',0,type=int)
    subject_id=request.args.get('subject',0,type=int)
    teacher_id=request.args.get('teacher',0,type=int)
    question=[(ques.id,ques.question) for ques in Questions.query.all()]
    chart_data=[]
    for key,value in question:
        ans_yes=Submissions.query.filter_by(submission=1,question_id=key,subject_id=subject_id,user_id=teacher_id).count()
        ans_no=Submissions.query.filter_by(submission=2,question_id=key,subject_id=subject_id,user_id=teacher_id).count()
        my_chart=PieChart("teacher_chart"+str(key),options={'title': 'Submission', "width": 500,"height": 300,"is3D":True})
        my_chart.add_column("string", "Answer")
        my_chart.add_column("number", "percent")
        my_chart.add_rows([["Yes", ans_yes],
        ["NO", ans_no]])
        chart_data.append(my_chart)
        charts.register(my_chart)
    print(chart_data)
    return self.render('admin/result_chart.html',stream_id=stream_id,

问题=问题，chart_data = chart_data）

result_chart.html

 <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<div class="container">
    <div class="row" >
    {% for key,question in question %}
        <p>{{key}},{{question}}</p>
        <br>
        {{ charts.teacher_chart+key }}
        {% endfor %}

    </div>
</div>
<!-- <script  type="text/javascript" src="{{ url_for('static',filename='js/jquery-3.2.1.min.js') }}"></script> -->
{{ charts_init }}

results.html

 <script type="text/javascript" charset="utf-8">
$(document).ready(function(){
    $("#teacher_select").on('click',function(){

            stream_id=$("stream_select").val();
            subject_id=$("subject_select").val();
            teacher_id=$("teacher_select").val();


        $('#showdata').load("{{url_for('results.load_chart')}}",'stream=stream_id')


    });

});

修改好的，所以除了 [Deprecation] Synchronous XMLHttpRequest 之外我还修复了动态图表问题但现在我遇到了一个新问题。我无法弄清楚如何以

的格式打印它

图表

chart_data这里是一个列表，而问题循环是列表中的元组。

views.py

@expose('/_charts',methods=["GET","POST"])
    def load_chart(self):
        stream_id=request.args.get('stream',0,type=int)
        subject_id=request.args.get('subject',0,type=int)
        teacher_id=request.args.get('teacher',0,type=int)
        question=[(ques.id,ques.question) for ques in Questions.query.all()]
        chart_data=[]
        for key,value in question:
            ans_yes=Submissions.query.filter_by(submission=1,question_id=1,subject_id=1,user_id=2).count()
            ans_no=Submissions.query.filter_by(submission=2,question_id=1,subject_id=1,user_id=2).count()
            # ans_no=Submissions.query.filter_by(submission=2,question_id=key,subject_id=subject_id,user_id=teacher_id).count()
            my_chart=PieChart("teacher_chart"+str(key),options={'title': 'Submission', "width": 500,"height": 300,"is3D":True})
            my_chart.add_column("string", "Answer")
            my_chart.add_column("number", "percent")
            print("\t\t\t",ans_no)

            my_chart.add_rows([["Yes", ans_yes],["NO", ans_no]])
            chart_data.append(my_chart.name)

            charts.register(my_chart)

        return self.render('admin/result_chart.html',stream_id=stream_id,question=question,chart_data=chart_data)
