我有一个复杂的JavaScript对象如下。搜索JavaScript对象中所有值的路径
一个例子对象:
var object= {
"name": "tfifkhul",
"id": "262761",
"children": [
{
"name": "rthrth",
"id": 0,
"children": [
{
"name": "test",
"id": "262762",
"children": []
}
]
},
{
"name": "rthsrth",
"id": 0,
"children": [
{
"name": "test",
"id": "262762",
"children": []
}
]
},
{
"name": "rthrthhrth",
"id": 0,
"children": [
{
"name": "test",
"id": "262762",
"children": [
{
"name": "rtjrtj",
"id": 0,
"children": [
{
"name": "fwefwefwef",
"id": "262768",
"children": []
}
]
},
{
"name": "hsrtjrtdjrtj",
"id": 0,
"children": [
{
"name": "we4yhesrhy",
"id": "262764",
"children": []
}
]
},
{
"name": "lol",
"id": "262763",
"children": [
{
"name": "fwefwefwef",
"id": "262768",
"children": [
{
"name": "87ok78",
"id": "262765",
"children": [
{
"name": "78o78",
"id": 0,
"children": [
{
"name": "we4yhesrhy",
"id": "262764",
"children": [
{
"name": "test1",
"id": 0,
"children": [
{
"name": "",
"id": "262766",
"children": []
}
]
},
{
"name": "test2",
"id": 0,
"children": [
{
"name": "",
"id": "262766",
"children": []
}
]
}
]
}
]
},
{
"name": "7o78o76o8",
"id": 0,
"children": [
{
"name": "",
"id": "262766",
"children": []
}
]
},
{
"name": "ko",
"id": 0,
"children": [
{
"name": "",
"id": "262767",
"children": []
}
]
}
]
}
]
}
]
}
]
}
]
}
]
};
我需要创建一个功能来搜索与给定值时关键的“ID”的所有匹配值。
到目前为止,我已创建了一个递归函数:
function searchOccurances(theObject, value,path) {
var result = null;
if(theObject instanceof Array) {
for(var i = 0; i < theObject.length; i++) {
result = searchOccurances(theObject[i],value,path+","+i);
}
}
else
{
for(prop in theObject) {
if(prop == 'id') {
if(theObject[prop] == value) {
keyOccurances.push(path);
}
}
if((theObject[prop] instanceof Array) || (theObject[prop] instanceof Object))
{
if((theObject[prop].length!=undefined)&&(theObject[prop].length!=0))
{
result = searchOccurances(theObject[prop],value,path+","+prop);
}
}
}
}
return result;
}
keyOccurances=[];
searchOccurances(object,262762,'');
console.log(keyOccurances);
//Output
[",children,0,children,0", ",children,1,children,0", ",children,2,children,0"] -- correct
keyOccurances=[];
searchOccurances(object,262768,'');
console.log(keyOccurances);
//Output
[",children,1,children,0,children,1,children,0", ",children,1,children,0,children,2,children,0"] --wrong
该函数返回匹配值的逗号分隔的路径阵列,但并不似乎正在正确的结果。对于值为'262762'的第一次调用给出了更正路径列表,但是值'262768'给出了不正确的路径列表。
请帮忙。
