问题描述
基本上，我只想在特定时间在asp.net应用程序中显示一个弹出框.所以我正在使用以下代码..
aspx页面:
Hi ,
Basically I want to display a popup box only at a specific time in asp.net application. so i''m using the following code..
aspx page :
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript">
function timedMsg()
{
var t=setTimeout("alert('good morning!')",6000);
}
</script>
</head>
C#代码:
C# code :
protected void Button1_Click(object sender, EventArgs e)
{
StringBuilder script = new StringBuilder();
script.Append("<script type=\"text/javascript\">");
script.Append("timedMsg();");
script.Append("</script>");
Page.ClientScript.RegisterClientScriptBlock(typeof(object), "JavaScriptBlock", script.ToString());
}
这工作正常，但我不想将settimeout设置为固定为6000.我需要从数据库中检索值并将其分配给settimeout.所以我修改了如下代码.
aspx页面:
this works fine but i dont want to set settimeout as fixed as 6000. i need to retrieve value from database and assign it to settimeout. so i modified the coding as below..
aspx page :
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript">
function timedMsg(var x)
{
var t=setTimeout("alert('I am displayed after 3 seconds!')",x);
}
</script>
</head>
C#代码:
C# code :
protected void Button1_Click(object sender, EventArgs e)
{
int x = 6000;
StringBuilder script = new StringBuilder();
script.Append("<script type=\"text/javascript\">");
script.Append("timedMsg("+x+");");
script.Append("</script>");
Page.ClientScript.RegisterClientScriptBlock(typeof(object), "JavaScriptBlock", script.ToString());
}
但是此代码无法正常工作.警报框没有弹出.这是将值传递给脚本的正确方法吗?还是要满足要求还需要做些什么?..请帮助我..
谢谢..
but this code is not working. the alert box is not popping up. is this a correct method to pass values to the script?. or what else to be done to meet the requirement?.. pls help me..
thanks..
推荐答案
function timedMsg(var x)
{
var t=setTimeout("alert('I am displayed after 3 seconds!')",x);
}
替换上面的代码
Replace the above code
function timedMsg(x)
{
var t=setTimeout("alert('I am displayed after 3 seconds!')",x);
}
