Question

Hi,
How to ensure 2nd button below is not there

to this code?

Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "ShowMessage('货币简称错误。');", true);

Answer 1

Hi @Peter_1985 ,
You need to provide the ShowMessage() JavaScript code so that we can help you solve the problem.
You can look at the usage of RegisterStartupScript Method https://learn.microsoft.com/en-us/dotnet/api/system.web.ui.clientscriptmanager.registerstartupscript?view=netframework-4.8
You can refer to the demo:

Code behind:

protected void Button1_Click(object sender, EventArgs e)  
{  
        Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "ShowMessage()", true);  
}

change the ShowMessage() function to allow this.

Answer 3

My best guess is you copied the Bootstrap modal sample code. Simply remove the HTML.

<button type="button" class="btn btn-primary">Save changes</button>

If this does not answer your question then you'll need to clarify how you expect the logic to work and provide sample code.
