我的示例 Json 对象如下所示:
{
"o": [
{
"level": 0,
"outlineItemId": 8,
"parentItemId": null,
"parentItem": null,
"order": 0,
"text": "section 1",
"isLeaf": "false",
"expanded": "true"
},
{
"level": 1,
"outlineItemId": 9,
"parentItemId": 8,
"parentItem": {
"level": 0,
"outlineItemId": 8,
"parentItemId": null,
"parentItem": null,
"order": 0,
"text": "section 1",
"isLeaf": "false",
"expanded": "true"
},
"order": 0,
"text": "sub 1",
"isLeaf": "false",
"expanded": "true"
},
{
"level": 2,
"outlineItemId": 10,
"parentItemId": 9,
"parentItem": {
"level": 1,
"outlineItemId": 9,
"parentItemId": 8,
"parentItem": {
"level": 0,
"outlineItemId": 8,
"parentItemId": null,
"parentItem": null,
"order": 0,
"text": "section 1",
"isLeaf": "false",
"expanded": "true"
},
"order": 0,
"text": "sub 1",
"isLeaf": "false",
"negateDevice": null,
"expanded": "true"
},
"order": 0,
"text": "sub sub 1",
"isLeaf": "true",
"expanded": "true"
}
]
}
早些时候,当树被配置为:
treeReader: {
level_field: "level",
parent_id_field: "parentItemId",
leaf_field: "isLeaf",
expanded_field: "expanded"
},
我正在显示正确的缩进和图像图标,但是当 json obj 始终具有“扩展”:“真”时它们没有被扩展,所以我尝试了下面的代码。
treeReader: {
level_field: "o.level",
parent_id_field: "o.parentItemId",
leaf_field: "o.isLeaf",
expanded_field: "o.expanded"
},
现在我没有得到图像图标,并且之前扩展的树现在是平的。
我的 Json 阅读器以防万一我搞砸了..
jsonReader: {
root: 'o',
id: 'o.outlineItemId',
parentItemId: 'o.parentItem.outlineItemId',
text: 'o.text',
repeatitems: false,
page: function(obj) { return 1; },
total: function(obj) { return 1; },
records: function(obj) { return obj.o.length; },
},
任何帮助将不胜感激。沙阿
