      "children":[ 
        {
          "name":"Dynamic Menu 1", 
          "reponsetype":"4",
          "ussdcode":"123*2",

Answer 1

您可以使用递归来实现。

尝试一下：

let arr = { "name": "123", "reponsetype": "2", "ussdcode": "123", "parrentussd": "0", "children": [{ "name": "1 Menu", "reponsetype": "2", "ussdcode": "123*1", "parrentussd": "123" }, { "name": "Menu 2", "reponsetype": "2", "ussdcode": "123*2", "parrentussd": "123", "children": [{ "name": "Dynamic Menu 1", "reponsetype": "4", "ussdcode": "123*2", "parrentussd": "123*2" }] }] }
let res = [];

function getChild(obj) {
  for (let i = 0; i < obj.children.length; i++) {
    if (obj.children[i].children) {
      getChild(obj.children[i]);
      delete obj.children[i].children;
      res.push(obj.children[i])
   } else {
      res.push(obj.children[i])
   }
 }
}
getChild(arr);
console.log(res);
