删除嵌套数组中的某一项
[{
"title": "parent",
"expanded": true,
"folder": true,
"id": "0",
"children": [
{
"title": "parent[0]",
"expanded": true,
"folder": true,
"id": "1",
"children": [
{"title": "Books", "id": "2"},
{"title": "Kindle Books", "id": "3"},
{"title": "Books For Study", "id": "4"},
{"title": "Audiobooks", "id":"5"}
]
},
{
"title": "parent[1]", "id": "6", "folder": true, "children": [
{"title": "Music", "id": "7"},
{"title": "MP3 Downloads", "id": "8"},
{"title": "Musical Instruments & DJ", "id": "9"},
]
}
]
}]
想根据id来删除数组中的某一项，数组长度不确定，是嵌套的，知道用递归。。但是不会写，哪位能帮忙写下。。

这样应该就可以了，你试试<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Document</title></head><body><script type="text/javascript">function call(arr,tag){ for(var i = arr.length ; i > 0 ; i--){ if(arr[i-1].id == tag){ arr.splice(i-1,1); }else{ if(arr[i-1].children){ call(arr[i-1].children,tag) } } }}var arr = [{'title': 'parent','expanded': true,'folder': true,'id': '0','children': [ { 'title': 'parent[0]', 'expanded': true, 'folder': true, 'id': '1', 'children': [ { 'title': 'Books', 'id': '2' }, { 'title': 'Kindle Books', 'id': '3' }, { 'title': 'Books For Study', 'id': '4' }, { 'title': 'Audiobooks', 'id': '5' } ] }, { 'title': 'parent[1]', 'id': '6', 'folder': true, 'children': [ { 'title': 'Music', 'id': '7' }, { 'title': 'MP3 Downloads', 'id': '8' }, { 'title': 'Musical Instruments & DJ', 'id': '9' }, ] }]}];call(arr,2); console.dir(arr);</script></body></html>
