Мне предоставляется строка B1-FEOL-SPUTTER-0015
, строка будет разделена на -
(тире), а затем использована для создания вложенного массива объектов.Это оригинальное дерево:
[{
"text": "B1",
"nodes": [{
"text": "FEOL",
"nodes": [{
"text": "SPUTTER"
}, {
"text": "COATING"
}, {
"text": "EXPOSING"
}, {
"text": "DEVELOP"
}, {
"text": "PLATING"
}, {
"text": "BOND"
}]
}, {
"text": "BEOL",
"nodes": [{
"text": "GRINDING"
}, {
"text": "BALLDROP"
}, {
"text": "PROBING"
}, {
"text": "BACKCOATING"
}, {
"text": "MARKING"
}, {
"text": "SORTING"
}, {
"text": "TUG"
}]
}]
}, {
"text": "B2",
"nodes": [{
"text": "FEOL",
"nodes": [{
"text": "SPUTTER"
}, {
"text": "COATING"
}, {
"text": "EXPOSING"
}, {
"text": "DEVELOP"
}, {
"text": "PLATING"
}, {
"text": "BOND"
}]
}, {
"text": "BEOL",
"nodes": [{
"text": "GRINDING"
}, {
"text": "BALLDROP"
}, {
"text": "PROBING"
}, {
"text": "BACKCOATING"
}, {
"text": "MARKING"
}, {
"text": "SORTING"
}, {
"text": "TUG"
}]
}]
}]
Я пытался использовать рекурсивные функции, вводя новые значения в .forEach(manipulateTree)
.Однако я не смог заставить его создать новые узлы в массиве, что должно быть сделано в операторе else
.
import fs from 'fs'
import path from 'path'
import util from 'util'
// This is avaliable in the link below, leading to pastebin
let tree = require('./server/configs/tree.json')
// The values I used to test:
// This works
// const newBranch = 'B1-FEOL-SPUTTER-0015'
// This doesn't
const newBranch = 'B3-ASDF-DSDF987SDF7-0015'
const locations = newBranch.split('-')
let nodes = {}
let iteration = -1
const manipulateTree = branch => {
iteration++
// Found node
if (branch.text === locations[iteration]) {
// Check if the iteration is second last in the branch array
if (iteration === locations.length - 2) {
branch.nodes.push({
'text': locations[iteration + 1],
'location': locations.join('-')
})
} else {
// If not then the recursive function will continue operation
if (branch.nodes && branch.nodes.length > 0) {
const found = branch.nodes.find(node => node.text === locations[iteration + 1])
if (found) {
branch.nodes.forEach(manipulateTree)
}
}
}
} else {
console.log('No such node')
if (iteration === locations.length - 1) {
branch = {
'text': locations[iteration],
'location': locations.join('-')
}
} else {
branch = {
'text': locations[iteration],
'nodes': []
}
}
}
return branch
}
if (tree && tree.length > 0) {
tree.forEach(manipulateTree)
}
console.log(util.inspect(tree, false, null, true))
Конечный результат, который мне нужен, таков:
