iterating through a nested JSON object
Hi,
I build a nested JSON object for a list of strings delimited by '-' to build a heirarchy. I was successfully able to get the nested JSON object from the Script below. However now I want to list this heirarchy in JSON object in HTML using div tags so I can indent children is this possible at all.?
var input = ["Fred-Jim-Bob", "Fred-Jim", "Fred-Thomas-Rob", "Fred"];
var output = [];
for (var i = 0; i < input.length; i++) {
var chain = inputi.split("-");
var currentNode = output;
for (var j = 0; j < chain.length; j++) {
var wantedNode = chainj;
var lastNode = currentNode;
for (var k = 0; k < currentNode.length; k++) {
if (currentNodek.name == wantedNode) {
currentNode = currentNode[k].children;
break;
}
}
// If we couldn't find an item in this list of children
// that has the right name, create one:
if (lastNode == currentNode) {
var newNode = currentNode[k] = {name: wantedNode, children: []};
currentNode = newNode.children;
}
}
}
output JSONifies as:
[{
"name": "Fred",
"children": [{
"name": "Jim",
"children": [{
"name": "Bob",
"children": []
}]
}, {
"name": "Thomas",
"children": [{
"name": "Rob",
"children": []
}]
}]
}]
