I stole this script from a different post:
function convertToHierarchy() {
var arry = [
{ "Id": "1", "Name": "abc", "Parent": "", "attr": "abc" },
{ "Id": "2", "Name": "abc", "Parent": "1", "attr": "abc" },
{ "Id": "3", "Name": "abc", "Parent": "2", "attr": "abc" },
{ "Id": "4", "Name": "abc", "Parent": "2", "attr": "abc" }
];
var nodeObjects = createStructure(arry);
for (var i = nodeObjects.length - 1; i >= 0; i--) {
var currentNode = nodeObjects[i];
if (currentNode.value.Parent === "") {
continue;
}
var parent = getParent(currentNode, nodeObjects);
if (parent === null) {
continue;
}
parent.children.push(currentNode);
nodeObjects.splice(i, 1);
}
console.dir(nodeObjects);
return nodeObjects;
}
function createStructure(nodes) {
var objects = [];
for (var i = 0; i < nodes.length; i++) {
objects.push({
value: nodes[i],
children: []
});
}
return objects;
}
function getParent(child, nodes) {
var parent = null;
for (var i = 0; i < nodes.length; i++) {
if (nodes[i].value.Id === child.value.Parent) {
return nodes[i];
}
}
return parent;
}
This script produces:
[{
"value": {
"Id": "1",
"Name": "abc",
"Parent": "",
"attr": "abc"
},
"children": [{
"value": {
"Id": "2",
"Name": "abc",
"Parent": "1",
"attr": "abc"
},
"children": [{
"value": {
"Id": "4",
"Name": "abc",
"Parent": "2",
"attr": "abc"
},
"children": []
}, {
"value": {
"Id": "3",
"Name": "abc",
"Parent": "2",
"attr": "abc"
},
"children": []
}]
}]
}]
What I'm looking for is:
[{
"Id": "1",
"Name": "abc",
"Parent": "",
"attr": "abc",
"children": [{
"Id": "2",
"Name": "abc",
"Parent": "1",
"attr": "abc",
"children": [{
"Id": "4",
"Name": "abc",
"Parent": "2",
"attr": "abc"
}, {
"Id": "3",
"Name": "abc",
"Parent": "2",
"attr": "abc"
}]
}]
}]
I need to get rid of "value" wrapper primarily, and the empty child node secondarily.
I know I can write a clean up script, but that would be less than best practice.
Would be great if someone knows how to fix, or suggest a different script!
Thanks
