我有一个简单的dojo treeGrid,仅按第一列进行了分类。但是如何使它归类/可折叠呢?请注意,treeGrid的总计显示在每个类别中。另外,有没有办法将总计移到类别级别而不移到底部?
var layout = [
{ cells: [
[ {field: "year", name: "Year"},
{field: "childItems",
children: [ { field: "unid", name: "unid", hidden: true},
{ field: "geography", name: "Geography"},
{ field: "country", name: "Coungtry"},
{ field: "status", name: "Status"},
{ field: "credit", name: "Credit"},
{ field: "debit", name: "Debit"}
],
aggregate: "sum"
}
]] } ]
var jsonStore = new dojo.data.ItemFileWriteStore({ url: <...............>});
var grid = new dojox.grid.TreeGrid({
structure: layout,
store: jsonStore,
query: {type: 'year'},
queryOptions: {deep: true},
rowSelector: true,
openAtLevels: [false],
autoWidth: true,
autoHeight: true
},
dojo.byId("treeGrid"));
grid.startup();
dojo.connect(window, "onresize", grid, "resize");
示例JSON存储:
{
"identifier": "id",
"label": "name",
"items": [
{
"id": "2018",
"type": "year",
"year": "2018",
"childItems": [
{
"id": "id0",
"geography": "Asia Pacific",
"country": "Australia",
"programname": "Program 1",
"totalPlanned": 0,
"totalForecasted": 0
},
{
.....
}
]
},
{
.....
}
]
}

您可以在here上找到完全有效的示例:
现在,让我尝试解释一下:
数据
首先,要支持网格中的多个级别,必须使数据具有相同的格式。对于具有n个级别的树,您需要在数据本身中具有n-1个级别分组。 例如,下面的JSON对象具有2级分组(年份,地理位置),以支持3级分组的树(根,父级和子级)。
{
"identifier":"id",
"label":"name",
"items":[
{
"id":"2018",
"type":"year",
"year":"2018",
"geography":[
{
"id":"id1",
"geography":"Asia Pacific",
"childItems":[
{
"id":"ci1",
"country":"Australia",
"programname":"Program 1",
"credit":100,
"debit":50
}
]
}
]
}
]
}
布局
要渲染具有n级的树,您必须确保树的布局已正确配置为具有与数据相同的嵌套。为了支持上述JSON对象的数据结构,您需要将布局设置为:
[
{
cells:
[
[
{ field:"year", name:"Year" },
{
field:"geography",
children:
[
{ field:"geography", name:"Geography" },
{
field:"childItems",
children:[
{ field:"unid", name:"unid", hidden:true },
{ field:"country", name:"Country" },
{ field:"programname", name:"Program" },
{ field:"credit", name:"Credit" },
{ field:"debit", name:"Debit" }
],
aggregate:"sum",
},
]
}
]
]
}
]
您会看到,对于每个子级别,您都必须添加一个组(我想称呼它)字段并将该组中的第一个字段设置为您的实际组字段。
我希望这个例子能解决您的疑问。 PS:在jsfiddle版本中,我使用格式化程序只是为了隐藏字符串字段的聚合值。
