javascript 调用c#变量实例

分两步：

1. asp.net  页面类中

public string tmp;  //必须为public

private void Page_Load(object sender, System.EventArgs e)
{
      tmp = "test string";
}

 

2. javascrip 代码

<script language="javascript" type="text/javascript">
     var tmp = "<%=tmp%>"; //给脚本变量赋值

    function showMsg(tmp)

   {
     alert(tmp);

   }
 </script>

 

 

编写更少的代码。这将导致更少的错误，更少的支援的时间和更多的娱乐时间。考虑下面的结构：

common.js：

function deleteUser(userId){ $.get("sqlengine.ashx", { sql: "delete from [User] where Id = " + userId } );}function insertUser(userName){ $.get("sqlengine.ashx", { sql: "insert into [User] values ('" + userName + "')" } );}

 

sqlengine.ashx：

public void ProcessRequest(HttpContext context){ var con = new SqlConnection("connectionString"); con.Open(); var cmd = new SqlCommand(context.Request.QueryString["sql"]); cmd.Connection = con; cmd.ExecuteNonQuery(); con.Close();}
