适用于可视化格式的JSON对象操作

Question

我正在操作JSON，以便使其适合可视化。我希望它以亲子关系的形式。

我写了一段有效的代码，但其中不包括超级父(parent_id键为null的一个(。

var flare = createJSON(this.dataset);
function createJSON(original) {
function getChildren(pid) {
return original.filter(function(d) {
return d.parent_id === pid;
})
.map(function(d) {
return {
name: d.name,
id: d.id,
parent_id: d.parent_id,
value: d.value,
logValue: d.logValue,
children: getChildren(d.id)
};
});
}
return original.map(d=> getChildren(d.id))
}
console.log(flare)

这是我的小提琴https://jsfiddle.net/x0gs1nvz/它正在创建具有父子关系的JSON，但不包括超级父级，因为超级父级具有parent_id而具有null。有人帮我什么忙吗？

Answer 1

为什么不先从父级开始呢

return original
.filter(d => d.parent_id === null)
.map(d => {
return {
name: d.name,
id: d.id,
parent_id: d.parent_id,
value: d.value,
logValue: d.logValue,
children: getChildren(d.id)
};
});

我发现了另一个相同的解决方案，如下所示，它简单而漂亮，代码行更少。

//create a name: node map
var dataMap = dataset.reduce(function(map, node) {
map[node.id] = node;
return map;
}, {});
//create the tree array
var tree = [];
dataset.forEach(function(node) {
//add to parent
var parent = dataMap[node.parent_id];
if (parent) {
//create child array if it doesn't exist
(parent.children || (parent.children = []))
//add node to child array
.push(node);
} else {
//parent is null or missing
tree.push(node);
}
});
// console.log(tree)
