說明：這是我做項目時自己寫的小例子，里面有冗余的參數。
開發環境 vs2012 asp.net mvc4 c#
1、顯示效果
2、HTML代碼
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="EchartsPic.aspx.cs" Inherits="MvcAppTest.EchartsPic" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

<script type="text/javascript">
var yearMax = 2017; $(function () { GetGSList(); }); function GetGSList() { var html = ''; $.ajax({ type: 'post', url: 'Home/GetEarthPartList', data: { yearId: yearMax }, dataType: 'json', success: function (d) { var legendText = new Array(); var maxInt = d.totalEH; var title3 = "用地分階段查詢"; var serailData = new Array(); $.each(d, function (index, val) { switch (index) { case 'wgEH': legendText.push('A類用地(畝)'); var obj = { value: val, name: 'A類用地(畝)' }; serailData.push(obj); break; case 'wjEH': legendText.push('B類用地(畝)'); var obj = { value: val, name: 'B類用地(畝)' }; serailData.push(obj); break; case 'gsEH': legendText.push('C類用地(畝)'); var obj = { value: val, name: 'C類用地(畝)' }; serailData.push(obj); break; case 'gxEH': legendText.push('D類用地(畝)'); var obj = { value: val, name: 'D類用地(畝)' }; serailData.push(obj); break; case 'ysEH': legendText.push('E類用地(畝)'); var obj = { value: val, name: 'E類用地(畝)' }; serailData.push(obj); break; case 'zjEH': legendText.push('F類用地(畝)'); var obj = { value: val, name: 'F類用地(畝)' }; serailData.push(obj); break; default: break; } }); var picObject = new CreatPicObject("工業用地分階段統計", "單位：畝", legendText, maxInt, title3, serailData); var myChart = echarts.init(document.getElementById('divPic')); myChart.setOption(picObject); }, error: function (d) { console.log(d); } }); } </script>
</head>
<body>
<div id="divPic" style="width:500px;height:500px;">
</div>
</body>
</html>
3、Home控制器的代碼
public JsonResult GetEarthPartList(string yearId) { EPTHZValueModel hzvalueModel = new EPTHZValueModel(); hzvalueModel.gsEH = 1200; hzvalueModel.gxEH = 800; hzvalueModel.plEH = 300; hzvalueModel.wgEH = 1300; hzvalueModel.wjEH = 2300; hzvalueModel.ysEH = 130; hzvalueModel.zjEH = 345; decimal[] myArray = new decimal[] { hzvalueModel.gsEH, hzvalueModel.gxEH, hzvalueModel.wgEH, hzvalueModel.wjEH, hzvalueModel.plEH, hzvalueModel.ysEH, hzvalueModel.zjEH }; hzvalueModel.totalEH = MaxO(myArray); return Json(hzvalueModel, JsonRequestBehavior.DenyGet); }
private decimal MaxO(decimal[] myList) { decimal a = 0, b = 0; for (int i = 0; i < myList.Length; i++) { a = b - myList[i]; if (a < 0) { b = myList[i]; } } return b; }
public class EPTHZValueModel { public System.Decimal totalEH { get; set; } public System.Decimal wgEH { get; set; } public System.Decimal wjEH { get; set; } public System.Decimal plEH { get; set; } public System.Decimal gsEH { get; set; } public System.Decimal gxEH { get; set; } public System.Decimal ysEH { get; set; } public System.Decimal zjEH { get; set; } }
