在JavaScript中，你可以使用
for...in循环和JSON.parse()方法来获取树形JSON数组中的所有ID。以下是一个示例：```javascript function getIdsFromJson(jsonArray) { var ids = []; for (var i = 0; i < jsonArray.length; i++) { var id = jsonArray[i].id; ids.push(id); } return ids; }
var jsonArray = [ { id: 1, children: [ { id: 2 }, { id: 3 } ] }, { id: 4, children: [ { id: 5 }, { id: 6 } ] } ];
console.log(getIdsFromJson(jsonArray)); // 输出: [1, 2, 3, 4, 5, 6] ```
在这个示例中，我们首先创建了一个名为
getIdsFromJson的函数，它接受一个JSON数组作为参数。然后，我们使用一个for...in循环遍历数组中的每个元素。对于每个元素，我们获取其id属性，然后将这个属性添加到ids数组中。最后，我们返回ids数组。
