我正在尝试使用lodash显示我拥有的JSON的所有值,就我所知,它最适合这种情况,如您所见,json很深,某些类别为空,这对我来说更具挑战性,我想知道哪个函数最适合显示这样的非结构化和深层JSON.是foreach还是filter？ Lodash是这里最好的选择吗？数据最终将显示在react应用程序中,但现在我正在尝试进行映射/ foreach /过滤器或可以动态遍历所有项目的任何内容.
预期的输出是列表项嵌套树. >
{
"name": "Menu","children": [
{
"type": "category","name": "Burgers","children": [
{
"type": "item","name": "Burger 1","children": [
{
"type": "modifier","name": "Promo","children": [
{
"type": "item","name": "Promo 1"

最佳答案
只要您处理了未知深度的数据,就应该使用递归.

}
let body = document.querySelector('body');
function print(obj){
let str = `<li>${obj.name}</li>`;
if(obj.children){
str += '<ul>'
for(let c of obj.children) str += print(c)
str += '</ul>'
}
return str;
}
document.body.innerHTML = print(obj);
