javascript - Adding dgrids with variable widths to TabContainer

Question

I'm populating a TabContainer with grids (Dojo 1.8, dgrid) that are showing the results of a query for different datasets. Each tab is the result of a single dataset. The different datasets will have a varying number of fields, so I'm dynamically building each grid and adding it to a ContentPane, which gets added to the TabContainer.

My current problem is seting the width of the grids when they are built. The datasets could have from two fields to upwards of 100 fields to be shown in the grid. I've set a default width in CSS for the grid of 600px, but the grid will only show the first six fields of the dataset. If I set the width to "auto", it is only as wide as the TabContainer, removing the scroll bar and cutting off the data. Is it possible to set a width for each grid separately?

This is what the result looks like

This is the code for populating the TabContainer

function buildColumns(feature) {
    var attributes = feature.attributes;
    var columns = [];

    for (attribute in attributes) {
        if (attribute != "Shape") {
            var objects = {};
            objects.label = attribute;
            objects.field = attribute;
            columns.push(objects);
        }
    }
    return columns;
}

function populateTC(results, evt) {
    try {
        if (dijit.byId('tabs').hasChildren) {
            dijit.byId('tabs').destroyDescendants();
        }

        if (results.length == 0) {
            console.log('Nothing found.');
            return;
        }

        var combineResults = {};
        for (var i = 0, len = results.length; i < len; i++) {
            var result = results[i];
            var feature = result.feature;
            var lyrName = result.layerName.replace(' ', '');
            if (combineResults.hasOwnProperty(lyrName)) {
                combineResults[lyrName].push(result);
            }
            else {
                combineResults[lyrName] = [result];
            }
        }

        for (result in combineResults) {
            var columns = buildColumns(combineResults[result][0].feature);
            var features = [];

            for (i = 0, len = combineResults[result].length; i < len; i++) {
                features.push(combineResults[result][i].feature);
            }

            var data = array.map(features, function (feature) {
                return lang.clone(feature.attributes);
            });

            var dataGrid = new (declare([Grid, Selection]))({
                id: "dgrid_" + combineResults[result][0].layerId,
                bufferRows: Infinity,
                columns: columns,
                "class": "resultsGrid"
            });


            dataGrid.renderArray(data);
            dataGrid.resize();

            dataGrid.on(".dgrid-row:click", gridSelect);

            var cp = new ContentPane({
                id: result,
                content: "<b>" + combineResults[result][0].layerName + "\b",
                //content: dataGrid,
                title: combineResults[result][0].layerId
            }).placeAt(dijit.byId('tabs'));

            cp.addChild(dataGrid);

            cp.startup();
            cp.resize();
        }
        tc.startup();
        tc.resize();
        map.infoWindow.show(evt.screenPoint, map.getInfoWindowAnchor(evt.screenPoint));
    }
    catch (e) { console.log(e.message); }
}

Answer 1

问题不在于网格宽度，而在于列宽。它们适合容器。

如果你给一列一个固定的宽度，你会得到想要的效果。

您应该能够设置样式.dgrid-cell或.dgrid-column-[index]

我还需要根据列数据进行更多控制。您可以通过为列提供自己的 renderHeaderCell 和 renderCell 方法来控制样式。（风格指dom-style）

renderHeaderCell: function(node) {
    style.set(node, 'width', '50px');
}

renderCell:  function(object, value, node) {
    style.set(node, 'width', '50px');
}

Answer 2

我能够使用 AddCssRule 动态更改网格的大小

var dataGrid = new (declare([Grid, Selection]))({
    id: "dgrid_" + combineResults[result][0].layerId,
    bufferRows: Infinity,
    columns: columns,
    "class": "resultsGrid"
});

dataGrid.renderArray(data);

var gridWidth = "width: " + String(columns.length * 100) + "px";
dataGrid.addCssRule("#" + dataGrid.id, gridWidth);
dataGrid.resize();
dataGrid.refresh();

这是一个显示结果的小提琴。单击彩色多边形以显示不同的网格（尽管有时会将内容推到网格的标题中）。此外，选项卡未正确呈现，但应该有 0、224 和 227（如果您还单击了一个点）。
