如何让 slickgrid div 根据表格大小调整大小

Question

我希望我们有一些熟悉 slickGrid 的用户也了解 StackOverflow 如何使用它 :)

我有一个包含我的 slickGrid 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>

      return {valid: false, msg: "This is a required field"};
    } else {
      return {valid: true, msg: null};
    }
  }

  var grid;
  var data = [];
  var columns = [

  ];
  var options = {

    autoEdit: true,
    multiColumnSort: true

  $(function () {

      var d = (data[i] = {});

      d["id"] = i;
      d["date"] = "06/31/2012";
      d["venue"] = "Sample Venue";
      d["event"] = "Sample Event";
      d["desc"] = "$45 Door";
      d["visible"] = (i % 5 == 0);
    }

    grid = new Slick.Grid("#myGrid", data, columns, options);

    grid.setSelectionModel(new Slick.CellSelectionModel());

    grid.onAddNewRow.subscribe(function (e, args) {
      var item = args.item;
      grid.invalidateRow(data.length);
      data.push(item);
      grid.updateRowCount();
      grid.render();
    });

    grid.onSort.subscribe(function (e, args) {
      var cols = args.sortCols;

      data.sort(function (dataRow1, dataRow2) {
        for (var i = 0, l = cols.length; i < l; i++) {
          var field = cols[i].sortCol.field;
          var sign = cols[i].sortAsc ? 1 : -1;
          var value1 = dataRow1[field], value2 = dataRow2[field];
          var result = (value1 == value2 ? 0 : (value1 > value2 ? 1 : -1)) * sign;
          if (result != 0) {
            return result;
          }
        }
        return 0;
      });
      grid.invalidate();
      grid.render();
    });
  })
</script>

<hr />EOP

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？如果我没有为 div "myGrid" 的高度设置值，它只是将它的高度设置为 0。我希望 div 随着它加载的网格的大小而扩展。

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

我知道它是特定于软件的，但真的希望我们有一些 slickGrid Guru，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，从而无需滚动条。

你可以找到一个例子here。

Answer 2

很遗憾，autoHeight 和 paging 不能一起使用。如果你想使用分页，你可以按如下方式自动调整表格的高度（一定要在渲染数据之前这样做）：

// 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' );

Answer 3

我建议在 onpagingInfoChanged 中添加以下代码

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，我将 2 px 添加到高度以确保 VScrollbar 不会出现，但我相信您可以找出更令人愉悦的东西。
