从ASP.net代码后面调用JavaScript函数 [英] Call JavaScript function from ASP.net code behind

问题描述

我正在尝试从后面的代码中调用JavaScript函数，但到目前为止还算不上成功.我试图在 Page_Load 方法内添加以下代码段.

I’m trying to call a JavaScript function from Code behind but no luck so far. I tried to add the following snippets inside Page_Load method.

我尝试了以下方法

ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "foo", "alert('test22222')", true);

也如下

Page.ClientScript.RegisterStartupScript(Type.GetType("System.String"), "addScript", "alert('test22222');", true);

没有人为我工作.我在这里想念什么吗?我想在加载页面之前显示警报消息.

None worked for me. Is there anything I’m missing here? I would like to show the alert message before loading the page.

任何帮助表示赞赏.谢谢.

Any help appreciated. Thanks.

推荐答案

您可以在page_prerender事件中实现它

you can implement it in page_prerender event

    protected void page_prerender( object sender, EventArgs e )
{
         your code here;
}
