Question

这是从asp.net代码调用javascript函数的代码：

aspx文件：

<%@ Page Language="C#" MasterPageFile="~/MasterPage.Master" AutoEventWireup="true" CodeBehind="Restaurants.aspx.cs" Inherits="WebApplication1.WebForm1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
    <script type="text/javascript">
        function alertMe() {
            alert('Hello');
        }
    </script>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="body" runat="Server">
</asp:Content>

aspx.cs文件：

     protected void Page_Load(object sender, EventArgs e)
            {
                if (!Page.IsPostBack)
                {
                    Page.ClientScript.RegisterStartupScript(this.GetType(), "CallMyFunction","alertMe()", true);
                 }
               }

问题：asp.net代码无法调用javascript函数我搜索了几个链接的解决方案： http://www.dotnetcurry.com/showarticle.aspx?ID=273 Calling JavaScript Function From CodeBehind http://www.devcurry.com/2009/01/execute-javascript-function-from-aspnet.html

但找不到解决方案。任何人都可以帮助我。

我不确定如何从cs代码中调用它，但是你不能把这样的东西放到你的aspx页面上吗？

 <script type="text/javascript">
    function alertMe() {
        alert('Hello');
    }

var isPostBack = '<%=Page.IsPostBack%>' == 'True' ? true : false;

if (!isPostBack){
   alertMe();
}
</script>
