arttemplate 后台返回的数据格式问题

1.

2.JSON.parse() 方法用于将一个 JSON 字符串转换为对象。

    $("body").on("click","#analyze",function(){
        $("#modal").modal("show");
        var url = "chartData";
        $.ajax({
           header:{
                Accept:"application/json; charset=utf-8"
            },
            method: 'get',
            url: url,
            success:function(data){
                data = JSON.parse(data);
                console.log(data);
                var html1 = template("standard-lists",data);
                $("#standard-answer").html(html1);
                var html2 = template("studentanswer-lists",data);
                $("#student-answer").html(html2);
            }
        })
    });

 3.循环，判断

<tbody id="student-answer">
                                                <script type="text/html" id="studentanswer-lists">
                                                    {{each sourceAndVoiceMusicList as sa}}
                                                    {{if sa.noteIsTrue==false}}
                                                    <tr class="anerror">
                                                    {{/if}}
                                                    {{if sa.noteIsTrue==true}}
                                                    <tr>
                                                    {{/if}}
                                                    
                                                        <td>{{sa.voiceNoteName}}</td>
                                                        <td>{{sa.rectifyNote}}</td>
                                                        <td>{{sa.voicePitchToFreq}}</td>
                                                        <td>{{sa.voiceNoteLength}}</td>
                                                        {{if sa.noteIsTrue==true}}
                                                        <td><span class="answer-right"></span></td>
                                                        {{/if}}
                                                        {{if sa.noteIsTrue==false}}
                                                        <td><span class="answer-error"></span></td>
                                                        {{/if}}
                                                        {{if sa.lengthIstrue==false}}
                                                        <td><span class="answer-error"></span></td>
                                                        {{/if}}
                                                        {{if sa.lengthIstrue==true}}
                                                        <td><span class="answer-right"></span></td>
                                                        {{/if}}
        
                                                    </tr>
                                            
                                                    {{/each}}
                                                </script>
                                            </tbody>

4.没有循环的数据显示格式

<script type="text/html" id="cardinal-list">
    <p>音符总数：{{noteCount }}</p>
    <p>音高正确数：{{noteNo}}</p>
    <p>音长正确数：{{lengthNo}}</p>
    <p>音准正确数：{{trueNO}}</p>
    <p>准确率：{{accuracy*100+"%"}}</p>
</script>

5.后台给的数据

    "voiceMusicList": [
        {
