)Di atas ialah tatasusunan, yang mengandungi maklumat menu Ia mungkin mempunyai banyak dimensi Sekarang ada soalan Jika id menu ialah 8, iaitu, indeksnya ialah $arr[4]['_child'][5]['_child'][8]. . Bagaimanakah saya boleh menulis menu ini? Fungsi mengembalikan tatasusunan yang mengandungi semua nilai indeks Contohnya, menu dengan id 8 mengembalikan [4,5,8].

_Child array Hanya tambahkan id menu induk pada setiap tatasusunan, dan kemudian baca lapisan demi lapisan melalui indeks, jika tidak, anda perlu untuk gelung untuk menilai tatasusunan demi tatasusunan. Kesannya terlalu teruk

function EachTree(json, id) {
var path = [];
for (var i = 0; i < json.length; i++) {
var arr = json[i], _id = arr["id"];
path.push(_id);
if (_id == id) {
return path;
}
if (arr["_child"] && arguments.callee(arr["_child"], id)) {
return path;
}
}
}
console.log(EachTree(json, 8));
