javascript - 使 json 字符串与饼图数据源的确切字符串匹配？如何

Question

这是我收到的 JSON 字符串

    "{Date:'15/05/2015',y:'6'},
     {Date:'01/08/2015',y:'6'},
     {Date:'02/08/2015',y:'6'},
     {Date:'08/08/2015',y:'72'},
     {Date:'09/08/2015',y:'6'},"

我必须使其与饼图中的数据源完全相同

    var datas = [
                  {date:"02/02/2015",y:6},
                  {date:"15/05/2015",y:6},
                  {date:"01/08/2015",y:6},
                  {date:"02/08/2015",y:6}
                   ];

这里正在工作 js fiddle js fiddle working for json

这是我用于制作 json 的 C Sharp 代码

        foreach (KeyValuePair<string, int> pair2 in dic)
        {
            int perce = pair2.Value;
            var perct = ((double)perce / total) * 100;
            int perc = Convert.ToInt32(perct);
            string datesval = pair2.Key;
            StringBuilder sb = new StringBuilder();
            sb.Append("Date:'" + datesval + "',y:" + perc + "");
            string newq = sb.ToString();
            list.Add(newq);

        }


     StringBuilder sb2 = new StringBuilder();
        foreach (string element in list)
        {
            for (int m = 0; m <= list.Count() - 1; m++)
            {
                sb2.Append("{" + list[m] + "},");
                line = sb2.ToString();

              }
            break;
        }

应使用 javascript 修改字符串

remove (") double quote from start of string and add [ . also remove (,") from end and add ]

还显示错误 Uncaught TypeError: undefined is not a function on line $('#container').highcharts({

使用字符串生成器和 eval ，我正在从您构建的行扩展上述内容

         string c = line;
        StringBuilder builder = new StringBuilder(c);
      //  builder.Replace(",\"","]");
       // builder[0] = '[';
        TrimEnd(builder,',');
       // builder.AppendFormat("[\"{0}\"]", builder.ToString());

        string combine = "["+ builder.ToString();
        string newcom = combine + "]";
        return newcom;
   }
    static void TrimEnd(StringBuilder builder, char letter)
    {
        // ... If last char matches argument, reduce length by 1.

        if (builder.Length == 0)
        {
            string c = "sorry";
        }
        else if (builder[builder.Length - 1] == letter)
        {
            builder.Length -= 1;
        }

    }

在 ajax 成功的情况下这样做

    var v = eval(response.d);

现在在饼图中使用它

第二个错误是因为 jquery 文件相互冲突，首先使用 jquery 1.9.1.js，然后使用图形文件
