试试这个来调用你的javascript来自代码:

  protected   void  Page_Load( object  sender,EventArgs e)
{
Page.ClientScript.RegisterStartupScript( this .GetType(),< span class =code-string> Call_my_function showError('你好这是来自服务器端的消息!') true );
}


 Page.ClientScript.RegisterStartupScript( this  .GetType(),  alert   showError('我是男孩'); true ); 





在您的代码隐藏中使用以上内容它应该可以工作..

解决方案

hi,
Try this to call your javascript from code behind:

protected void Page_Load(object sender, EventArgs e)
    {
        Page.ClientScript.RegisterStartupScript(this.GetType(), "Call_my_function", "showError('hello this is a message from server side!')", true);
    }


Page.ClientScript.RegisterStartupScript(this.GetType(),"alert","showError('I am a boy');",true);



Use the above in your code-behind and it should work..
