问题描述
我正在使用JSON和getJSON函数等,我正在尝试从JSON中获取数据,这些数据可以包含多个级别并且可以有多个子级。在那一刻,我可以看到我想要的值.each与另一个.each,例如:
I'm new working with JSON and the getJSON function etc and I'm trying to get data from a JSON that goes down several levels and can have multiple children. At the minute I can see the values I want by using .each with another .each such as:
$.each(data, function(i, value1) {
$.each(value1, function(i, value2) {
$.each(value2, function(i, value3) {
$.each(value3, function(i, value4) {
$.each(value4, function(i, value5) {
$.each(value5, function(i, value6) {
alert ("we got "+i);
});
唯一的问题是,我赢了我总是知道JSON中有什么内容,它可以拥有无限的孩子。那么我将如何让它变得如此动态?
The only problem is, I won't always know what is in the JSON and it could have unlimited children. So how would I go about making it dynamic as such?
基本上我正在寻找的东西是什么东西继续检查孩子,直到它达到最低水平。
Basically what I'm looking for is something to keep checking for children until it gets to the lowest level.
另外,我知道最后的值是无论价值在哪里的索引JSON,
Also, I know the value i at the very end is the index for whatever value is in the JSON,
有没有办法自动化这个,以便我可以检查比方说,JSON中的'name'会返回'name'的值吗?
Is there any way to automate this also so that I could check for say, 'name' in the JSON and it would return the value of 'name'?
以下是我正在尝试使用的JSON示例:
Here is a sample of the JSON i'm trying to work with:
[
{
"children": [
{
"children": [
{
"children": [
{
"children": [
{
"bucketPath": "AUDIO\\audio0.mp3",
"id": 305,
"modified": "2012-08-02T10:06:52",
"name": "audio0.mp3",
"state": "closed"
}
推荐答案
使用递归:
function recurse(name, obj) {
if (!obj || typeof obj != "object")
alert("found leaf '"+name+"': "+obj);
else
$.each(obj, recurse);
}
recurse("root", data);
编辑:根据您的JSON,可以制作它更具体:
Based on your JSON, one could make it more specific:
function recurse(arr) {
for (var i=0; i<arr.length; i++)
for (var prop in arr[i])
if (prop == "children") // && arr[i].children instanceof Array
recurse(arr[i].children);
else
alert("we got "+prop+": "+arr[i][prop]);
}
recurse(data);
