Hi Everybody

I use from a repeater for get last 3 news from database.
I want show only the first news in page load and after 3 second I want show second news instead of first news and after 3 second I want show third news instead of second news and after 3 second I want show first news instead of third news and ...

I implement bellow code that show only one of the news randomly. Please edit my java script for doing this action.

ASP.NET

<div id="RightContext">
    <asp:SqlDataSource runat="server" ID="DataSource"
        ConnectionString="<%$ConnectionStrings:Database %>"
        SelectCommand="GetNews"
        SelectCommandType="StoredProcedure"></asp:SqlDataSource>
 
    <asp:Repeater runat="server" ID="Repeater" DataSourceID="DataSource">
        <ItemTemplate>
            <div class="News-Ticker" id="TickerID">
                <h3><%#Eval("Title") %></h3>
                <span>Reference:<%#Eval("Reference") %></span>
                <br />
                <span>Date:<%#Eval("IssueDate") %></span>
                                        
            </div>
        </ItemTemplate>
    </asp:Repeater>
 
    <script type="text/javascript">
 
        var News = document.getElementById("RightContext");
        var current = Math.floor(Math.random() * 3);
 
        for (var i = 2; i >= 0; i--) {
            if (i != current) {
                News.children[i].parentNode.removeChild(News.children[i]);
            }
        }
 
    </script>
 
</div>

The above logic is to display only one message choose by random. So there is no logic exist to display the message as you expect.

I remove 2 news of 3 news therefore exist one news and page will be show that news.
I want change this news after some second without user action.

The current variable randomizes a number. You should use that variable to keep the article(news) that is currently displayed and use it to change to a new article after three seconds.

news was fetched from DB therefore I can fetched that in Java script. If you can do this please give me more information how I can use from a variable in java script that was fetched from data base?

Try the below logic. Hope it helps you, instead of the multiple divs with class 'News-Ticker' use repeater. Thats it. Post your feedback whether it works or not, so that we can fix'em up.
