jQuery-垂直浮动DIV
原标题:jQuery - vertically floating DIV

我有一个应用程序,它有三列布局,内容从左列到右列(当然还有后列)来回移动。在两者之间,有一个“命令菜单”——你可以根据诸如此类的事情来做。

交易是这样的——左边的项目是垂直排列的,你可以在上面表演。我想让命令菜单跟随鼠标(垂直,但在其列内),这样当选择一个项目进行操作时,菜单就会垂直对齐。

我完全(最好是?)愿意用jQuery做这件事,但我的尝试失败了。

以下是当前标记:

<table class="stuff_area">
    <tr>
        <td id="stuff_left">
            <div class="shipmentList">
                <asp:Literal ID="ltrShipments" runat="server"></asp:Literal>
            </div>
        </td>
        <td id="stuff_controls" class="stuff_area_input">
            <div id="follower">
                <input id="btnAll" type="button" value="All" /><br/>
                <input id="btnNone" type="button" value="None" /><br />
                <input id="btnStuff" type="button" value=">>" /><br />
            </div>
        </td>
        <td id="stuff_right"></td>
    </tr>
</table>

I m specifically interested in making the div with class="follower" float up an down. FWIW, I can t get any movement, so there is a good chance that getting me some vertical movement (I want to limit its movement to up/down) will get you the win.

想法?

最佳回答
  $(function() {
    $(".stuff_area td").mouseenter( function( event ) {
      $("#follower").offset({ top: $(this).offset().top });
    } );
  });

偏移量方法应该可以执行您想要的操作。我假设您的服务器控件创建了一个表,如果没有,请用更合适的选择器替换.stuff_area td
