JavaScript return false not stopping postback on link control

Hi there the postback would be avoided only when the function returns false in the case when it returns true it would be send the page to the server. Please look at the following example which will make your doubt clear enough.

<script type="text/javascript">

        function display(e) {
            return true;
        }


        function displayFalse(e) {
            return false;
        }
    </script>
    <form id="form1" runat="server">
    <div>
        <a  id="A1" href="Test.aspx" class="vnlink" onclick="return display(event);">Submit_true</a>
        <a  id="btn11" href="Test.aspx" class="vnlink" onclick="return displayFalse(event);">Submit_false</a>
    </div>
    </form>

But it's not worknig , u can see in my query that i have mentioned the same thing . return false is not working .

please give us some other alternate solution.

It will not work when your function returns true to check try both the where return false;
