Question

我正在用 asp.net C# 创建图表，准备 JSON 字符串格式的图表数据，并将 JSON 发送到 Java Script 以进行图表渲染

我在后面的 C# 代码中准备了 JSON，然后将其发送到 Java 脚本

这是我的 JSON

{
   "chart":{

      "theme":"carbon",
      "valueFontColor":"000000",
      "rotateValues":"0"
   },
   "data":[
      {
         "label":"AN INTEGRATED SYSTEMS LLC",
         "value":"859050",
         "link":"newchart-json-AN INTEGRATED SYSTEMS LLC"
      },
      {
         "label":"BAHAN N",
         "value":"623295",
         "link":"newchart-json-BAHAN N"
      }
      
   ],
   "linkeddata":[
      {
         "id":"CO TA L.L.C.",
         "linkedchart":{
            "chart":{
               "captionLinkedChart":"",
               "theme":"carbon"
            },
            "data":[
               {
                  "label":"AN INTEGRATED SYSTEMS LLC",
                  "value":"859050"
               },
               {
                  "label":"Total",
                  "value":"41722065"
               }
            ]
         }
      }
   ]
}

这是我调用 JSON 的脚本

     <script>
     var json = '<%=jsonString%>';
     
    FusionCharts.ready(function() {
      var satisfactionChart = new FusionCharts({
        type: 'column2d',
        renderAt: 'chart-container',
        width: '400',
        height: '300',
        dataFormat: 'json',
        dataSource: json,
        
      });
</script>




public partial class MYPAGE: System.Web.UI.Page 

{
 public string jsonString = "";
 protected void Page_Load(object sender, EventArgs e) 
{ 
jsonString = SendJson(); 
}

和SendJson();将从 SQL 中获取数据并准备 JSON 格式

JSON , Uncaught SyntaxError: Unexpected identifier
