如何让光滑网格 div 根据表格的大小调整大小

Question

我希望我们有一些熟悉slickGrid的用户看到StackOverflow如何使用它也:)

我有一个包含我的光滑网格的 HTML，如下所示：

  <div style="position:relative; overflow:visible; width:600px; margin:25px 0 0 0;">
    <div id="myGrid" style="width:100%;overflow:visible; min-height:100px; max-height:300px;"></div>
  </div>
  <div class="options-panel">
    <h2>Demonstrates:</h2>
    <ul>
      <li>adding basic keyboard navigation and editing</li>
      <li>custom editors and validators</li>
      <li>auto-edit settings</li>
    </ul>
    <h2>Options:</h2>
    <button onclick="grid.setOptions({autoEdit:true})">Auto-edit ON</button>
    &nbsp;
    <button onclick="grid.setOptions({autoEdit:false})">Auto-edit OFF</button>
  </div>

          var sign = cols[i].sortAsc ? 1 : -1;
          var value1 = dataRow1[field], value2 = dataRow2[field];

我想要的是让我的 slickGrid 收集数据，然后让div 自动调整大小以包含更新的网格。 目前看来div 大小必须静态设置？ 如果我不设置div "myGrid" 的高度值，它只是将其高度设置为 0。 我希望div 随着它加载的网格的大小而扩展。

gitHub（https://github.com/mleibman/SlickGrid/wiki/_pages）上的slickgrid文档非常有限（公平地说，作者承认这一点）。 我在谷歌上也遇到了很多麻烦。

我知道它是特定于软件的，但真的希望我们有一些光滑的网格大师，因为这个工具看起来很棒！

Answer 1

您可以使用

autoHeight选项来实现此目的。

  options = {
    ...
    autoHeight: true
  };

包含的div 将展开以容纳整个网格，从而避免使用滚动条。

您可以在此处找到示例。

Answer 2

我建议将以下代码添加到 onpagingInfoChanged

dataView.onPagingInfoChanged.subscribe(function (e, pagingInfo) {
//......
///******************************************************
    var divSize = 2 + (options.rowHeight * (pagingInfo.pageSize +1)); 
    $("#myGrid").css( 'height' , divSize+'px' )
    grid.resizeCanvas()
///*******************************************************
});

有点懒惰，我在高度上添加了 2 px 以确保 VScrollbar 不会出现，但我相信你可以找到更令人愉悦的东西。

不幸的是，自动高度和分页不能一起使用。 如果要使用分页，可以按如下方式自动调整表的高度（请务必在呈现数据之前执行此操作）：

// Determine the total width of the grid div element
var gridWidth = 0;
for( i in columns )
{
    if( columns[i].width != null && columns[i].width != 0 )
    {
        // Use the specified width
        gridWidth += columns[i].width;
    }
    else
    {
        // If the column width is not specified, or is zero, try to use the default column width
        if( columns[i].defaultColumnWidth == null ) // If default also does not exist
            gridWidth += 80;                        // Pick an arbitrary default width (could replace with CSS property)
        else
            gridWidth += columns[i].defaultColumnWidth;
    }
}

// Calculate the height of the Div by adding the values of the header row height and the row height * # rows
var rowH = (options.rowHeight != null ? options.rowHeight : 25); // If no rowHeight is specified, use the default size 25 (could be set by CSS)
var headerH = 0;
// First, determine whether to account for the header row
if( options.showHeaderRow == null || options.showHeaderRow == true )
{  
    // If so, use specified height, or default height
    if( options.headerRowHeight == null )
        headerH = 25;
    else
        headerH = options.headerRowHeight;        
}
// Set the table size
var divSize = (json.length * rowH) + headerH + 1;
$j("#myGrid").css( 'height' , divSize+'px' )
             .css( 'width'  , gridWidth+'px' );
