我有一个包含状态列的数据源。我还有一个数组PART_STATUS，其中包含所有可能的状态。
是否可以在该列中显示具有所有PART_STATUS状态的下拉菜单，并选择正确的选项？

最佳答案
可能的解决方案＃1
您可以使用“更新”功能，并在columnSettings中为要使用的组合编辑器指定STATUS列。 PART_STATUS将充当STATUS单元中组合编辑器的数据源。
例如，您可以添加:
$.ig.loader({
//...
resources: "igGrid.Paging.Updating,igCombo"
});
//...
$("#grid1").igGrid({
//...
features: [
{
name: "Updating",
editMode: "cell",
columnSettings: [
{
columnKey: "STATUS",
editorType: "combo",
editorOptions: {
dataSource: PART_STATUS
}
}
]
}
]
});
可能的解决方案2
另一种处理方式使得组合最初可见，这是无需更新，而是为“状态”列创建模板，并在该列的每一行上创建一个新的组合。
由于将不会显示更新，这意味着需要手动保存数据。
着色也可以实现，我已经介绍了如何实现。它会在每个组合上使用。
//...
var PART_STATUS = [
{"Name": "Out For Cleaning", "TextColor": "black", "BackgroundColor": "white"},
{"Name": "Out For Repair", "TextColor": "white", "BackgroundColor": "red"},
{"Name": "Out For Refurb", "TextColor": "black", "BackgroundColor": "white"},
{"Name": "Need Cleaning", "TextColor": "black", "BackgroundColor": "white"},
{"Name": "Need Repair", "TextColor": "black", "BackgroundColor": "white"},
{"Name": "Need Refurb", "TextColor": "white", "BackgroundColor": "blue"},
{"Name": "Removed", "TextColor": "black", "BackgroundColor": "white"},
{"Name": "Cleaned", "TextColor": "white", "BackgroundColor": "green"},
{"Name": "Repaired", "TextColor": "black", "BackgroundColor": "yellow"},
{"Name": "Refurbished", "TextColor": "black", "BackgroundColor": "white"}
];
$.ig.loader(function () {
$("#grid1").igGrid({
//...
columns: [
//...
{ headerText: "Status", key: "STATUS", dataType: "string", width: "200px", template: "<input class='combo' value='${STATUS}'/>"}
],
rowsRendered: function () {
$(".combo").igCombo({
dataSource: PART_STATUS,
width: "100%",
enableClearButton : false,
//Template for the dropdown items when clicking on the arrow so they have colors as well:
itemTemplate: "<div style='color: ${TextColor}; background-color:${BackgroundColor};' title='${Name}'>${Name}</div>",
//Assign text color and background color for the initially selected value:
create: function(evt, ui) {
var inTextColor = $(evt.target).data("igCombo").options.dataSource[$(evt.target).data("igCombo").selectedIndex()].TextColor;
var inBgColor = $(evt.target).data("igCombo").options.dataSource[$(evt.target).data("igCombo").selectedIndex()].BackgroundColor;
$(evt.target).css({ 'color': inTextColor, 'background-color': inBgColor});
},
selectionChanged: function (evt, ui) {
//Update data source, so the new selected value would be saved
var rowId = parseInt(ui.owner.element.closest("tr").attr("data-id"));
$("#grid1").data("igGrid").dataSource.setCellValue(rowId, "STATUS", ui.items[0].value, true);
//Update text color and background color when changing a new value
var newTextColor = ui.owner.options.dataSource[ui.owner._activeID].TextColor;
var newBgColor = ui.owner.options.dataSource[ui.owner._activeID].BackgroundColor;
ui.owner.element.css({ 'color': newTextColor, 'background-color': newBgColor});
}
});
}
});
});
