我正在使用以下 Infragistics 组件来查看分层数据。http://www.igniteui.com/tree/drag-and-drop-single-tree
我已经像下面一样初始化了树视图，以查看最初扩展的树的所有节点。如果我错过了显示所有最初折叠的节点的选项，有人可以建议我吗？
$("#tree").igTree({
checkboxMode: "off",
singleBranchExpand: true,
nodeClick: function (evt, ui) {
if (ui.node.data.Folder == "") {
var agreements = [];
var entry = [];
entry.push(ui.node.data.AgreementNbr);
entry.push(ui.node.data.ExternalDescription);
entry.push(ui.node.data.Description);
entry.push(ui.node.data.EffDate);
entry.push(ui.node.data.ExpDate);
entry.push(ui.node.data.ReleaseStatus);
agreements.push(entry);
$('#example').DataTable({
responsive: true,
columns: [
{ title: "Agreement Number" },
{ title: "External Description" },
{ title: "Description" },
{ title: "Effective Date." },
{ title: "Expiry Date" },
{ title: "Release Status" }
],
data: agreements,
destroy: true,
processing: true,
});
}
else {
var output = ui.node.data.Folder.map(function (obj) {
var a = [obj.AgreementNbr, obj.ExternalDescription, obj.Description, obj.EffDate, obj.ExpDate, obj.ReleaseStatus];
return Object.keys(a).map(function (key) {
return a[key];
});
});
console.log(output);
$('#example').DataTable({
responsive: true,
columns: [
{ title: "Agreement Number" },
{ title: "External Description"},
{ title: "Description"},
{ title: "Effective Date"},
{ title: "Expiry Date"},
{ title: "Release Status"}
],
data : output,
destroy: true
});
}
},
