你可以使用JavaScript和Python分别编写函数来删除指定路径的数据。以下是JavaScript和Python的示例代码：
JavaScript函数：
function removeDataByLabel(data, labelPath) {
for (let i = 0; i < data.length; i++) {
const item = data[i];
if (item.label === labelPath[0]) {
if (labelPath.length === 1) {
data.splice(i, 1);
i--;
} else if (item.children) {
removeDataByLabel(item.children, labelPath.slice(1));
if (item.children.length === 0) {
delete item.children;
}
}
}
}
}
const a = [
{ label: 1, prop: 1 },
{
label: 2,
children: [
{ label: 21, prop: 21 },
{ label: 22, prop: 22 },
],
},
{
label: 3,
children: [{ label: 21, prop: 21 }],
},
];
removeDataByLabel(a, [2, 21]);
console.log(a);
Python函数：
def remove_data_by_label(data, label_path):
i = 0
while i < len(data):
item = data[i]
if item["label"] == label_path[0]:
if len(label_path) == 1:
data.pop(i)
elif "children" in item:
remove_data_by_label(item["children"], label_path[1:])
if not item["children"]:
del item["children"]
i += 1
a = [
{"label": 1, "prop": 1},
{
"label": 2,
"children": [
{"label": 21, "prop": 21},
{"label": 22, "prop": 22},
],
},
{
"label": 3,
"children": [{"label": 21, "prop": 21}],
},
]
remove_data_by_label(a, [2, 21])
print(a)
这两个函数将会移除包含指定路径的数据。在JavaScript中，我们使用递归函数来遍历并删除数据，而在Python中，我们使用迭代方式实现相同的逻辑。
