My sample Json object is shown below:
{
"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"
}
]
}
Earlier when the tree was configured as:
treeReader: {
level_field: "level",
parent_id_field: "parentItemId",
leaf_field: "isLeaf",
expanded_field: "expanded"
},
I was displaying the correct indentation and image icons, however they were not expanded when the json obj always had "expanded":"true" so i tried the below code.
treeReader: {
level_field: "o.level",
parent_id_field: "o.parentItemId",
leaf_field: "o.isLeaf",
expanded_field: "o.expanded"
},
Now I am not getting the Image icons and the tree which was expanded earlier is now flat.
My Json reader just in case i goofed up..
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; },
},
Any help will be appreciated. Shah
Got it!
For the reader i had to include cell:'' and remove the o. references. and also loaded:true in the json object.
