导航到新页面并显示警报框 [英] Navigate to a new page and display an alert box
问题描述
我正在使用ASP.Net WebForm开发应用程序.用户单击按钮后,应用程序将导航到新页面并提示欢迎使用JackiesGame"对话框
I am developing an application by using ASP.Net WebForm. Once user click a button, application will navigate to a new page and prompt out a dialog box "Welcome to JackiesGame"
但是,我可以导航到新页面,但不会显示警报对话框.
However, I able to navigate to new page but the alert dialog box does not display.
以下是我的示例代码
void cmdCancel_Click(object sender, EventArgs e)
{
HttpContext.Current.Response.Redirect(Globals.NavigateURL(TabId), true);
Page page2 = HttpContext.Current.CurrentHandler as Page;
ScriptManager.RegisterStartupScript(page2, page2.GetType(), "alertMessage", "alert('Insert Successfully')", true);
}
推荐答案
在第2页中添加以下内容.在页面加载时,它将仅在页面首次加载脚本时进行注册.
Add the following in page 2. On the page load it will register only for the first time the page loads the script.
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
var reg = Request["Welcome"]
if(reg != null && reg.ToString() == "yes"){
ScriptManager.RegisterStartupScript(this, this.GetType(), "alertMessage", "alert('Insert Successfully')", true);
}
}
}
重定向后的所有代码都将被忽略,因为它必须重定向到新页面.因此,代码永远不会被触发.
All code after the redirect is getting ignored since it has to redirect to a new page. So the code never gets triggered.
编辑 添加了一个示例,说明了它的外观
EDIT Added a example of how it can look further
void cmdCancel_Click(object sender, EventArgs e)
{
string myUrl = Globals.NavigateURL(TabId)+"?Welcome=yes";
HttpContext.Current.Response.Redirect(myUrl, true);
}
