我刚刚编写了一个节点js代码,你仍然可以使它在js中的浏览器上工作,但是你需要下载下划线库here。
_und = require('underscore');
data = [{
"id": 1,
"children": [{
"id": 7,
"children": [{
"id": 8,
"children": [{
"id": 4
}, {
"id": 5
}, {
"id": 11
}
]
}, {
"id": 9
}
]
}, {
"id": 6
}, {
"id": 10
}
]
}, {
"id": 2,
"children": [{
"id": 3
}, {
"id": 12
}
]
}, {
"id": 13
}
]
function parse_tree_2(n) {
return(_und.map(n, parse_tree));
}
function parse_tree(n) {
if (n['children']) {
return({id: n['id'], children: parse_tree_2(n['children'])});
} else {
return({id: n['id']});
}
}
result = _und.map(data, parse_tree);
console.log("Result: %j", result);
你可以把到一个文件中,并与节点执行它(通过下载与强调NMP安装节点)。
在普通的js它会是这样的:
<script type="text/javascript" src="http://underscorejs.org/underscore-min.js"></script>
<script type="text/javascript">
data = [{
"id": 1,
"children": [{
"id": 7,
"children": [{
"id": 8,
"children": [{
"id": 4
}, {
"id": 5
}, {
"id": 11
}
]
}, {
"id": 9
}
]
}, {
"id": 6
}, {
"id": 10
}
]
}, {
"id": 2,
"children": [{
"id": 3
}, {
"id": 12
}
]
}, {
"id": 13
}
]
function parse_tree_2(n) {
return(_.map(n, parse_tree));
}
function parse_tree(n) {
if (n['children']) {
return({id: n['id'], children: parse_tree_2(n['children'])});
} else {
return({id: n['id']});
}
}
result = _.map(data, parse_tree);
console.log("Result: %j", result);
</script>
Ruby代码:
require 'json'
data = <<EOF
[{
"id": 1,
"children": [{
"id": 7,
"children": [{
"id": 8,
"children": [{
"id": 4
}, {
"id": 5
}, {
"id": 11
}
]
}, {
"id": 9
}
]
}, {
"id": 6
}, {
"id": 10
}
]
}, {
"id": 2,
"children": [{
"id": 3
}, {
"id": 12
}
]
}, {
"id": 13
}
]
EOF
json = JSON.parse(data)
def parse_tree(n)
if n["children"]
{id: n["id"], children: n['children'].map {|c| parse_tree(c)} }
else
{id: n["id"]}
end
end
result = json.map {|n| parse_tree(n) }
puts result
你说的 “父数据” 是指? – sawa 2013-04-04 04:43:43
即父母ID。 – user456064 2013-04-04 05:02:22
更新您的问题,然后将该数组作为结果添加到该数据样本中,然后我会在5或10分钟内为您提供代码。不要删除问题,它是一个有效的问题,我很乐意为您提供帮助。 – rorra 2013-04-04 05:13:12
