我正在尝试用每个节点的路径创建一个树:
Plunkr实际演示(仅参见控制台):https://plnkr.co/edit/peCIZcSzChF3b2WnaOxk?p=preview
原始数据: (这是标签列表,“父”是父ID)
var originals=[
{"id":1,"name":"Grammaire","parent":null},
{"id":2,"name":"Orthographe","parent":null},
{"id":8,"name":"Orthographe lexicale","parent":2},
{"id":9,"name":"Orthographe grammaticale","parent":2},
{"id":10,"name":"Adjectif couleur","parent":9},
{"id":11,"name":"Nombre","parent":8},
{"id":12,"name":"Annalyse grammaticale","parent":1},
{"id":19,"name":"Concordance des temps","parent":1},
{"id":20,"name":"annalyse 2","parent":12}
];
所以应该制作一个这样的树:
1-Grammaire
12-Annalyse grammaticale
20-Annalyse 2
19-Concordance des temps
2-Orthographe
8-Orthographe lexicale
9-Orthographe grammaticale
10-Adjectif couleur
11-Nombre
我得到了一个代码:
function convert(array){
var map = {};
for(var i = 0; i < array.length; i++){
var obj = array[i];
obj["children"] = [];
map[obj.id] = obj;
var parent = obj.parent || '-';
if(!map[parent]){
map[parent] = {
children: []
};
}
map[parent].children.push(obj);
}
return map['-'].children;
}
结果:
[
{"id":1,"name":"Grammaire","parent":null,
"children":[
{"id":12,"name":"Annalyse grammaticale","parent":1,
"children":[{"id":20,"name":"annalyse 2","parent":12,"children":[]}]
},
{"id":19,"name":"Concordance des temps","parent":1,"children":[]}
]},
{"id":2,"name":"Orthographe","parent":null,
"children":[
{"id":8,"name":"Orthographe lexicale","parent":2,
"children":[
{"id":11,"name":"Nombre","parent":8,"children":[]}]
},
{"id":9,"name":"Orthographe grammaticale","parent":2,
"children":[{"id":10,"name":"Adjectif couleur","parent":9,"children":[]}]
}
]
}
]
问题!
例如,对于id = 20
的节点 {"id":20,"name":"annalyse 2","parent":12,"children":[]}
我需要为此节点获取父节点id和名称,如下所示:
{"id":20,"name":"annalyse 2","parent":12,"children":[]
"parentNodes"= [{"id":1,"name":"Grammaire"},{"id":12,"name":"Annalyse grammaticale"},{"id":20,"name":"annalyse 2"}]
}
我不想要循环解决方案,因为我已经制作并制作了我的代码错误,因为我需要克隆这个对象。
欢迎任何帮助,我知道我必须做一个递归函数谁添加“路径”但我失败直到现在 谢谢
答案 0 :(得分:0)
可能需要一些修复但是有效!
function setPath(array){
function initPath(node,liste){
liste.push({"id":node.id,"name":node.name});
node["path"] = tools_clone(liste) ;
for(var n in node.children){
initPath(node.children[n],tools_clone(liste));
}
}
for(var i = 0; i < array.length; i++) {
var p = [];
initPath(array[i],p);
}
}
var r = convert(originals);
setPath(r);
