filteredKeylist = [key for key, values in keyDict.items() if filterString in values]
当我不确定key2的位置时,如何获得key2的孩子?
答案 0 :(得分:0)
var keys = Object.keys(data);
这将返回键名称的字符串数组。 ["key1", "key2"]
我认为你需要:
var childnames = Object.keys(data[key2]);
您可以通过以下方式将其转换为这些对象的数组:
var key2children = [];
for(var i=0; i< childnames.length; i++){
key2children.push(data[key2][cildnames[i]);
}
编辑也许这有帮助?:
//To get the children of an object
function getChildObjects(tgtobj){
var objchildren = [];
objectkeys = Object.keys(tgtobj);
for(var i=0; i< objectkeys.length; i++){
key2children.push(tgtobj[objectkeys[i]);
}
return objectchildren;
}
//This could be used to get the children of a child object in a function like this:
function getChildOjectsOfChildByName(tgtobj, name){
return getChildObjects(tgtobj[name]);
}
//usage example:
var key2childojects = getChildOjectsOfChildByName(data, "key2");

您必须使用for循环和递归来获取嵌套密钥。
function searchObj(obj, searVal){
for (ii in obj){
if(ii === searVal){
console.log(ii, ' -- my key');
} else{
console.log(ii, ' -- no key here');
searchObj(obj[ii], searVal);
}
}
}
searchObj(data, 'child21');
