<div id="Menudiv" style="background-color: White; border: 1px solid #cccccc; padding: 10px;
        display: none; position: absolute;">
        <ul>
            <li>测试1</li>
            <li>测试2</li>
            <li>测试3</li>
        </ul>
    </div>

 <script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script>
 <script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>

<script type="text/javascript">
    $(function() {
        $("#testdiv ul li").each(function() {
            $(this).bind("contextmenu", function(e) {
                var e = e || window.event;
                $("#Menudiv").css({ display: "block" });
                 if (! -[1, ]) {
                    e.cancelBubble = true; //IE下阻止事件传播
                    e.returnValue = false;
                }
                else {
                    e.stopPropagation();   //Firefox,opera,chrome下阻止事件传播
                }
                return false;   //这句一定要加，否则会弹出浏览器默认的右键菜单
            });
        });
        $(document).click(function() {
            $("#Menudiv").css({ display: "none" });
        });
