wx-charts 微信小程序图表 -- radarChart C# .net .ashx 测试

radarChart：原始代码

new wxCharts({
    canvasId: 'radarCanvas',
    type: 'radar',
    categories: ['1', '2', '3', '4', '5', '6'],
    series: [{
        name: '成交量1',
        data: [90, 110, 125, 95, 87, 122]
    }],
    width: 320,
    height: 200,
    extra: {
        radar: {
            max: 150
        }
    }
});

 

 

C#：服务器关键代码：

        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
            StringBuilder sb = new StringBuilder();
  
            sb.Append("{");
            sb.Append("\"XCXArray\":");
            sb.Append("[");
            sb.Append("{");
            sb.Append("\"canvasId\": \"radarCanvas\", ");
            sb.Append("\"type\": \"radar\", ");
            sb.Append(" \"categories\":[\"1\", \"2\", \"3\", \"4\", \"5\", \"6\"], ");
            sb.Append(" \"series\": [{ ");
            sb.Append("\"name\": \"成交量1\", ");
            sb.Append("\"data\": [90, 110, 125, 95, 87, 122] ");
            sb.Append("}], ");
            sb.Append("\"width\": 320, ");
            sb.Append("\"height\": 200 "); 

            sb.Append("}");
            sb.Append("]");
            sb.Append("}");

            context.Response.Write(sb.ToString());
        }

 

 

JS:关键代码

 /**
   * 生命周期函数--监听页面加载
   */
  onLoad: function (options) {

    var that = this;
    /*
      这个地方非常重要，重置data{}里数据时候setData方法的this应为
      以及函数的this, 如果在下方的sucess直接写this就变成了wx.request()
      的this了 url: 'http://comsn.cn/Msm/HerNeo.ashx',
    */
    wx.request({
      url: 'http://localhost:51887/HandlerTest.ashx', //访问服务器 URL
      data: {
        'TypeID': "0",
        'ImageID': '',
        'Name': ''
      },
      method: 'POST',
      header: {
        'content-type': 'application/x-www-form-urlencoded'
      },
      success: function (res) {
        var dddf = res.data.XCXArray;  // 获取 Charts 参数
        that.setData({
          XCXArray: res.data
        })
        console.log(dddf);
        console.log(dddf[0].series[0].name);
----------------------------------------------------------
------- 配置 Charts 参数 参数
        new wxCharts({
          canvasId: dddf[0].canvasId,
          type: dddf[0].type,
          categories: dddf[0].categories,
          series: [{
            name: dddf[0].series[0].name,
            data: dddf[0].series[0].data  
          }],
          width: dddf[0].width,
          height: dddf[0].height,
          extra: {
            radar: {
              max: 150
            }
          }
        }); 
------------------------------------------------------
      },
      fail: function (res) {
        console.log('submit fail');
      },
      complete: function (res) {
        console.log('submit complete'); 
      }
    }) 
   
  },
