javascript - 在选定的 gridview 行旁边自动滚动 detailsview

Question

我有一个 ASP.NET GridView ，它有几个关联的详细信息 View 和一个辅助 GridView 。当用户单击 gridview 中的一行时，detailsviews 会在 gridview 的右侧弹出。这很好，但是随着 gridview 行数的增加，详细信息 View 在页面上被推得越来越低，使用户很难找到它们，并且令人沮丧。

我想做的是当用户选择他们感兴趣的行时，将详细信息 View 的顶部与所选行对齐。

我试过设置 CSS:

[id$="ContentPlaceHolder1_dvProductionReport"], 
[id$="ContentPlaceHolder1_dvOraclePartDetails"], 
[id$="ContentPlaceHolder1_gvReceipts"] 
{
    position: fixed;
}

这没有用。我还尝试使用 this example 通过 JavaScript 定位它(在此示例中仅使用第一个选择器) :

<script type="text/javascript" src="https://code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript">
    $().ready(function () {
        //var $scrollingDiv = [id$ = "ContentPlaceHolder1_dvProductionReport"];
        var elements = document.querySelector('[id$="ContentPlaceHolder1_dvProductionReport"]');
        console.log(elements);

        $(window).scroll(function () {
            elements
                .stop()
                .animate({ "marginTop": ($(window).scrollTop() + 30) + "px" }, "slow");
        });
    });
</script>

但这在 Chrome 中不起作用，因为显然“animate”是 Chrome 中的关键字，但是 example适用于 Firefox。

问题:

我如何在用户滚动时保持细节 View 在 View 中，或者至少弹出与他们选择的 GridView 中的行对齐的细节 View ？

编辑:回应@rexroxm 的建议:我已经添加: <div style="position: absolute"><td>...</td></div>围绕第一个细节 View 。这没有任何区别，所以我将其添加到 .CSS 文件中:

[id$="ContentPlaceHolder1_dvProductionReport"], 
[id$="ContentPlaceHolder1_dvOraclePartDetails"], 
[id$="ContentPlaceHolder1_gvReceipts"] 
{
    position: absolute;
}

我可以看到 position: absolute; 的 CSS显示在所有三个相关的详细信息 View (2) 和 GridView (1) 上。如果我在 Chrome > Inspect > Developer tools 中检查样式，我会看到 position: absolute;在第一个 View 中显示了所有三个，但在第二个 View 中显示了它(不确定这些被称为什么，但它们会向您显示您选择的元素的 CSS 样式)。我也试过使用:

[id$="ContentPlaceHolder1_dvProductionReport"], 
[id$="ContentPlaceHolder1_dvOraclePartDetails"], 
[id$="ContentPlaceHolder1_gvReceipts"] 
{
    position: absolute !important;
}

这也显示为划线。

这是整个 <td>...</td> ，很抱歉，它很长，但它可能会有所帮助:

        <td>
        <div style="position: absolute">

Answer 1

您可以保留 detailsview 的 position:absolute 这样它将保留在您的页面/ View 中。当有人在主 gridview 中单击用户时，您可能会将其数据绑定(bind)到辅助 gridview，然后显示它。在容器 div/table 的 style 中将其 position 设置为 absolute 将使它保持在 View 中。您还可以在包含辅助 Gridview 的 div 的右上角放置一个十字按钮，它使用事件 onclick 设置 display:none。
