[英]Rename each object in a nested JSON structure to its .name property if possible
I'm looking for a way in which I can achieve the following transformation: 我正在寻找一种可以实现以下转换的方法:
The following code contains the old + new structure: 以下代码包含新旧结构:
function test_cleanHierarchyUp() {
console.log("Test for cleaning up hierarchy")
// I don't have children, so just keep me as is.
var bottom_level_object = {
'test': 'testest',
'more test': 'test',
'test': ''
}
var middle_object = {
children: bottom_level_object,
Name: "Middle Yeah!"
}
var original_object = [{
Name: "I am a name",
RandomName: '',
Children: middle_object
},
{
Name: "I am a name too",
Children: bottom_level_object
}
]
console.log("-----")
console.log("Source object: ")
console.log(original_object)
// Target structure:
// I don't have children, so just keep me as is.
var bottom_level_object_new = {
'test': 'testest',
'more test': 'test'
}
// Empty string (object 'Random') was removed from object.
var middle_object_new = {
"Middle Yeah!": {
children: bottom_level_object,
Name: "Middle Yeah!"
}
}
var target_object = {
"I am a name": {
Name: "I am a name",
Children: middle_object_new
},
"I am a name too": {
Name: "I am a name too",
Children: bottom_level_object_new
}
}
console.log("-----")
console.log("Target object: ")
console.log(target_object)
}
I did try: Recursion still hasn't dropped for me, unfortunately. 我确实尝试过:不幸的是,递归对我而言仍然没有放弃。 A minor addition is in the code, in the same recursion function I'd like to remove all attributes for which the value is an empty string.
在代码中,在相同的递归函数中做了一个小小的添加,我想删除所有值为空字符串的属性。
// Hierarchy Clean up functions
// Todo with this datastructure
// - How do I remove all fields with value of ""
// - For each object in the tree, change the object's key into its 'Name' attribute
function cleanHierarchyUp(obj) {
// obj is an array of objects, with or without a 'children' object (array of objects again)
// Goal: the object name should be its '.Name' name attribute if it exists
// Goal: if possible: all 'keys' for which the value is an empty string should be removed.
obj.forEach(function(element, index) {
// console.log(element)
if (element.Children) {
obj[element.Name] = cleanHierarchyUp(element)
} else {
obj[element.Name] = element
}
})
return obj
}
Help or direction is greatly appreciated. 帮助或指示,不胜感激。
I believe this does what you want: 我相信这可以满足您的需求:
function createObjectFromArray(objArr) {
console.log('objArr', objArr);
var newObject = {};
objArr.forEach(function(object, index) {
if (!object.hasOwnProperty('Name') || object.Name.length < 1) return;
var objectName = object.Name;
console.log(objectName)
newObject[objectName] = {};
newObject[objectName] = setObjectKeys(object, newObject[objectName])
});
console.log('newObject', newObject)
return newObject;
}
function setObjectKeys(object, newObject) {
Object.keys(object).forEach(function(key){
if ((typeof object[key] == 'string')) {
if (object[key].length > 0) {
newObject[key] = object[key];
}
} else if (keyIsObject(object, key)) {
newObjectKey = key;
if(object[key].Name) {
newObjectKey = object[key].Name;
}
newObject[newObjectKey] = setObjectKeys(object[key], {});
} else {
newObject[key] = object[key];
}
});
return newObject;
}
function keyIsObject(object, key) {
return Object.prototype.toString.call(object[key]) === '[object Object]';
}
var bottom_level_object = {
'test': 'testest',
'more test': 'test',
'test': ''
}
var middle_object = {
children: bottom_level_object,
Name: "Middle Yeah!"
}
var original_object = [{
Name: "I am a name",
RandomName: '',
Children: middle_object
}, {
Name: "I am a name too",
Children: bottom_level_object
}];
createObjectFromArray(original_object);
