C#与JavaScript互相调用

1、C#调用JavaScript

(1)准备好JavaScript函数

       <script type="text/javascript">
 
               function say() {
 
                   alert("CSharp调用js,调用成功!");
 
               }
 
      </script>

(2)页面代码
<asp:Button ID="Button1" runat="server" Text="CSharp调用js" onclick="Button1_Click" />
(3)C#代码
    protected void Button1_Click(object sender, EventArgs e)
    {
        Page.ClientScript.RegisterStartupScript(ClientScript.GetType(), "say", "<script>say(); </script>");
    }

2、JavaScript调用C#代码

(1)页面代码

        <input type="button" value="js调用CSharp" onclick="jsCallCSharp();" />
        <asp:Button ID="Button2" runat="server" Text="我是隐藏按钮" onclick="Button2_Click" style="display:none;"/>

(2)C#代码

    //后台方法 
    public void Show()
    {
        Response.Write("js调用后台方法成功!");
    }

    //隐藏按钮事件
    protected void Button2_Click(object sender, EventArgs e)
    {
        Show();
    }

(3)JavaScript代码

           <script type="text/javascript"> 
  
               function jsCallCSharp() {
 
                   document.getElementById("Button2").click();
 
               }
 
      </script>
