当用到.net 时，很多新手都为如何解决.cs文件里数组赋值给.aspx中js数组的问题。这次主要和大家分享怎么解决这个问题！
 
第一步：定义cs数组

cs代码：using System.Data;using System.Configuration;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;using System.Data.SqlClient;public partial class _Default : System.Web.UI.Page

{

    public double[] la = new double[25]; //定义为公共数组

    public double[] ln = new double[25];

    public int[] id = new int[25];

    public int k1 = 0;  //定义为公共,用于赋值循环

    protected void Page_Load(object sender, EventArgs e)

    {

            }

}

第二步：将cs数组赋值

string mycnnConnectionString1 = System.Configuration.ConfigurationManager.AppSettings["strcon"].ToString();    //创建连接字符串

        SqlConnection mycnn1 = new SqlConnection(mycnnConnectionString1);

        mycnn1.Open();

        SqlCommand cmd1 = new SqlCommand("select id,lat,lng from station  ", mycnn1);

        SqlDataReader dr1 = cmd1.ExecuteReader();

        int k2 = 0;

        int k3 = 0;

        int k4 = 0;

        string buf1 = "";

        double buf2 = 0;

        double buf3 = 0;

        int buf4 = 0;

        while (dr1.Read())

        {

            //lat

            buf2 = (double)dr1["lat"];

            la[k2] = buf2;

            k2++;

            //lng

            buf3 = (double)dr1["lng"];///数据库读取float型的数据要用double

            ln[k3] = buf3;

            k3++;

            //id

            buf4 = (int)dr1["id"];

            id[k4] = buf4;

            k4++;

        }

第三步：将cs数组赋值个js数组

aspx代码:

.........

 <script type="text/javascript">

//赋值的代码要写在这里<script type="text/javascript">代码...</script>

         var jingdu= new Array();

         var weidu=new Array();

         var id=new Array();<%

   for(int i=0;i<25;i++){

  %>

         jingdu.push(<%=ln[i]%>);

         weidu.push(<%=la[i]%>);

         id.push(<%=id[i] %>);

  <% 

   }

  %></script>
