我尝试使用protected void Page_Load(object sender, EventArgs e)
{
string connectionString;
SqlConnection cnn;
connectionString = @"Data Source=(LocalDb)\.;Initial Catalog=asp-Points;Integrated Security=True;AttachDBFilename=|DataDirectory|\Database1.mdf";
cnn = new SqlConnection(connectionString);
cnn.Open();
SqlCommand command;
SqlDataReader dataReader;
string sql, Output = "";
sql = "Select [Point] from [dbo].[table]";
command = new SqlCommand(sql, cnn);
dataReader = command.ExecuteReader();
// This logic to handle subtraction of data from database.
while (dataReader.Read())
{
int point = Convert.ToInt16(dataReader.GetValue(0));
if (prev != -1)
{
calcedPoint = point - prev;
Output = Output + calcedPoint.ToString() + "</br>";
}
prev = point;
}
Response.Write(Output);
dataReader.Close();
command.Dispose();
cnn.Close();
}
每10秒显示一次跨度，但似乎没有生效。当前，即使没有10秒，跨度也会连续显示。如何解决？
setIntervalvar i = 0;
var messages = {from: {type: "Other"}};
var myInterval = setInterval(function() {
if (i === 2) return clearInterval(myInterval);
if (messages.from.type === "Other") {
$('.chat_converse').append("<span class='msg_item'>lorem ipsum</p></span>");
}
$('.chat_converse').append("<span class='msg_item2'>textextext</p></span>");
i++;
}, 10000);
我需要期望的是每10秒显示2个跨度，并在每2个跨度之后显示附加的附录。
预期输出：

<div class="chat_converse"></div>
