这是我正在处理的JSON对象:
var r={
"id": "A",
"name": "Analysis",
"url": "A.html",
"root": true,
"children": [
{
"id": "B",
"name": "Introduction",
"url": "B.html",
"root": true,
"children": [{
"id": "C",
"name": "Creating",
"url": "c.html#I1"
}, {
"id": "D",
"name": "Running",
"url": "d.html#I2"
}]
},
{
"id": "E",
"name": "Transient Analysis",
"url": "E.html",
"root": true,
"children": [{
"id": "F",
"name": "RC",
"url": "F.html#T1"
}, {
"id": "G",
"name": "RLC",
"url": "G.html#T2"
}]
}
]
}
我希望这是另一个键值
path="home.html"
它不仅应该附加到根节点,还应该附加到它的所有子节点。
所以看起来应该是这样。
var r= {
"id": "A",
"name": "Analysis",
"url": "A.html",
"path":"home.html",
"root": true,
"children": [
{
"id": "B",
"name": "Introduction",
"url": "B.html",
"root": true,
"path":"home.html",
"children": [{
"id": "C",
"name": "Creating",
"url": "c.html#I1",
"path":"home.html"
}, {
"id": "D",
"name": "Running",
"url": "d.html#I2",
"path":"home.html"
}]
},
{
"id": "E",
"name": "Transient Analysis",
"url": "E.html",
"root": true,
"path":"home.html",
"children": [{
"id": "F",
"name": "RC",
"url": "F.html#T1",
"path":"home.html"
}, {
"id": "G",
"name": "RLC",
"url": "G.html#T2",
"path":"home.html"
} ]
}
]
}
到目前为止,我试过这个:
r.path={"home.html"}
和
var to_concatjson = JSON.parse(r);
to_concatjson["path"] = {"home.html"};
但两者都不适合我。
上述问题的进一步修改:
假设我正在从我的文件1加载我的json内容
文件1看起来像
[
{
"id":"a", "name":"a","children":[
{ "id":"b", "name":"b","children":[
{ "id":"b", "name":"b"},
{ "id":"c", "name":"c"},
{ "id":"d", "name":"d"}
]
},
{ "id":"e", "name":"e","children":[
{ "id":"f", "name":"f"},
{ "id":"g", "name":"g"},
{ "id":"h", "name":"h"}
]
},
]
}
]
我的json文件的内容加载在result [0]中。当我调用addPath时:
result[0]=addPath(result[0]);
它向我显示一个错误,“forEach”将不起作用,因为它不是对象的属性。
答案 0 :(得分:2)
使用此代码执行此操作: -
function addPath(obj){
if(!obj.hasOwnProperty('path')){
obj.path = 'home.html';
}
if(obj.hasOwnProperty('children')){
obj.children.forEach(function(obj1){
obj1 = addPath(obj1);
});
}
return obj;
}
r = addPath(r);
答案 1 :(得分:0)
我知道我的方式不是最佳的,但它正在发挥作用:
我通过 .replace(...)
(没有循环)
var r = JSON.parse(JSON.stringify(r).replace(new RegExp("\"url\"", 'g'), '"path": "home.html", "url"'));
console.log(r);
var r={
"id": "A",
"name": "Analysis",
"url": "A.html",
"root": true,
"children": [
{
"id": "B",
"name": "Introduction",
"url": "B.html",
"root": true,
"children": [{
"id": "C",
"name": "Creating",
"url": "c.html#I1"
}, {
"id": "D",
"name": "Running",
"url": "d.html#I2"
}]
},
{
"id": "E",
"name": "Transient Analysis",
"url": "E.html",
"root": true,
"children": [{
"id": "F",
"name": "RC",
"url": "F.html#T1"
}, {
"id": "G",
"name": "RLC",
"url": "G.html#T2"
}]
}
]
}
var r = JSON.parse(JSON.stringify(r).replace(new RegExp("\"url\"", 'g'), '"path": "home.html", "url"'));
console.log(r);
