在调整主网格大小时调整子网格列的大小

时间：2013-01-08 13:34:53

标签： jquery jqgrid

我使用下面的示例代码来创建带有subGrids的jqGrid。

在我的情况下，我删除了subGrids的标题。所以，它看起来像是一个分组。

这里，每当我调整主网格列的大小。我检查了jqGrid文档，发现＆＃34; resizeStop ＆＃34;返回列id和新宽度。

但是，没有找到类似setSize的列。

你的问题非常有趣，但答案并不容易。然而，我投入了一些时间并为您提供了the following demo，其中展示了如何实施解决方案。该实现基于对the source code内部函数dragEnd的分析，该函数将在mouseup回调内部调用（请参阅here）。列标题上的mousemove回调（请参阅here）和mousedown（请参阅here）一起播放。

结果the demo调整子网格列的大小：

enter image description here

我在演示中包含了在调整列大小后调整整个网格大小的技巧。它最初在the answer中描述。我在每个生产网格中都使用它，因为我更喜欢没有滚动条的网格。

下面我将包含演示的完整代码（全部来自document.ready处理程序）：

var myData = [
        {
            id: "10",
            c1: "My Value 1.1",
            c2: "My Value 1.2",
            c3: "My Value 1.3",
            c4: "My Value 1.4",
            subgridData: [
                { id: "10", c1: "aa", c2: "ab", c3: "ac", c4: "ad" },
                { id: "20", c1: "ba", c2: "bb", c3: "bc", c4: "bd" },
                { id: "30", c1: "ca", c2: "cb", c3: "cc", c4: "cd" }
            ]
        },
        {
            id: "20",
            c1: "My Value 2.1",
            c2: "My Value 2.2",
            c3: "My Value 2.3",

        $subgrid.closest("div.ui-jqgrid-view")
            .children("div.ui-jqgrid-hdiv")
            .hide();
    },
    resizeStop: function (newWidth, index) {
        // grid.dragEnd()
        var widthChange = this.newWidth - this.width,
            $theGrid = $(this.bDiv).find(">div>.ui-jqgrid-btable"),
            $subgrids = $theGrid.find(">tbody>.ui-subgrid>.subgrid-data>.tablediv>.ui-jqgrid>.ui-jqgrid-view>.ui-jqgrid-bdiv>div>.ui-jqgrid-btable");
        $subgrids.each(function () {
            var grid = this.grid;
            // we have subgrids which have no internal subgrids
            // it reduce the number of columns to 1
            // we have rownumbers: true in the main grid, but not in subgrids
            // it reduce the number of columns to additional 1
            // so we should use (index - 2) as the column index in the subgrids
            grid.resizing = { idx: (index - 2) };
            grid.headers[index - 2].newWidth = (index - 2 === 0) || (index - 1 === grid.headers.length) ? newWidth - 2 : newWidth;
            grid.newWidth = grid.width + widthChange;
            grid.dragEnd.call(grid);
            $(this).jqGrid("setGridWidth", grid.newWidth, false);
        });
        $theGrid.jqGrid("setGridWidth", this.newWidth, false);
    }
}).jqGrid("navGrid", "#pager", {add: false, edit: false, del: false});

更新：The answer根据上述解决方案的代码引入了新的setColWidth方法。一个使用新的setColWidth方法来简化resizeStop的代码。
