リストビューがあります。編集、更新、削除をクリックしたときにページが何度も読み込まれないようにしたいです。編集をクリックして行を編集すると、ページはポストバックを実行します。ポストバックを実行しないために何をする必要がありますか。

My code is


     <script type="text/javascript">
    $(document).ready(function() {
    $.ajax({
    type: "POST",
    contentType: "application/json; charset=utf-8",
    url: "TestOrigin.aspx/BindDatatable",
    data: "{}",
    dataType: "json"

    });
    });
    </script>
    <script type="text/javascript">

    function javascriptfunction()
    {
    return false;
    }
    </script>

関数の前にreturnを置く

OnClientClick="return javascriptfunction()"

そして最後にjava-script関数で書き込みます

return false;
