Grouping by fields after reduce is not working in JavaScript - javascript

There is a complex object and based on an array which is given as an input I need to modify its properties. Illustration is shown below. If the "field" is same , add them to "or" array .If its different "field" add them to "and" array along with its "value". I am using Set to get keys from both source and input and using them to group based on its keys. Also whenever there are duplicates .ie., suppose the "filterObj" already has the same (field, value) pair. Be it in "and" or inside "or",Then don't add it in the final object
Sandbox: https://codesandbox.io/s/optimistic-mirzakhani-pogpw-so-dpvis
There is a TestCases file in the sandbox which its needs to pass
let filterObj = {
feature: "test",
filter: {
and: [{ field: "field2" }]
}
};
let obj = [{ field: "field2", value: "3" }];
let all_filters = [];
if (filterObj.filter.and && filterObj.filter.and.hasOwnProperty("or")) {
all_filters = [...filterObj.filter.and.or];
} else if (filterObj.filter.and) {
all_filters = [...filterObj.filter.and];
}
const all_objs = [...obj, ...all_filters];
const uniqKeys = all_objs.reduce(
(acc, curr) => [...new Set([...acc, curr.field])],
[]
);
const updateItems = uniqKeys.map(obj => {
const filter_items = all_objs.filter(item => item.field === obj);
let resultObj = {};
if (filter_items && filter_items.length > 1) {
resultObj.or = [...filter_items];
} else if (filter_items && filter_items.length === 1) {
resultObj = { ...filter_items[0] };
}
return resultObj;
});
var result = { ...filterObj, filter: { and: [...updateItems] } };
console.log(result);

Try it.
I redid the implementation, it happened more universally.
Parses any filters according to your algorithm that it finds.
All test cases are worked.

A way to convert an object with keys of . seperated strings into a JSON object

I'm trying to figure out a way to turn and object like this :
{ "test.subtest.pass" : "test passed", "test.subtest.fail" : "test failed" }
into JSON like this:
{ "test": { "subtest": { "pass": "test passed", "fail": "test failed" }}}
sometimes there may be duplicate keys, as above perhaps there would be another entry like "test.subtest.pass.mark"
I have tried using the following method and it works but it's incredibly ugly:
convertToJSONFormat() {
const objectToTranslate = require('<linkToFile>');
const resultMap = this.objectMap(objectToTranslate, (item: string) => item.split('.'));
let newMap:any = {};
for (const [key,value] of Object.entries(resultMap)) {
let previousValue = null;
// #ts-ignore
for (const item of value) {
// #ts-ignore
if (value.length === 1) {
if(!newMap.hasOwnProperty(item)) {
newMap[item] = key
} // #ts-ignore
} else if (item === value[value.length - 1]) {
if(typeof previousValue[item] === 'string' ) {
const newKey = previousValue[item].toLowerCase().replace(/\s/g, '');;
const newValue = previousValue[item];
previousValue[item] = {};
previousValue[item][newKey] = newValue;
previousValue[item][item] = key;
} else {
previousValue[item] = key;
}
} else if (previousValue === null) {
if (!newMap.hasOwnProperty(item)) {
newMap[item] = {};
}
previousValue = newMap[item];
} else {
if (!previousValue.hasOwnProperty(item)) {
previousValue[item] = {}
previousValue = previousValue[item];
} else if (typeof previousValue[item] === 'string') {
const newValue = previousValue[item];
previousValue[item] = {};
previousValue[item][item] = newValue;
} else {
previousValue = previousValue[item];
}
}
}
}
return newMap;
}
We can utilize recursion to make the code a little less verbose:
function convertToJSONFormat(objectToTranslate) {
// create root object for the conversion result
const result = {};
// iterate each key-value pair on the object to be converted
Object
.entries(objectToTranslate)
.forEach(([path, value]) => {
// utilize a recursive function to write the value into the result object
addArrayPathToObject(result, path.split("."), value);
});
return result;
}
function addArrayPathToObject(root, parts, value) {
const p = parts.shift();
// base-case: We attach the value if we reach the last path fragment
if (parts.length == 0) {
root[p] = value
return;
}
// general case: check if root[p] exists, otherwise create it and set as new root.
if(!root[p]) root[p] = {};
addArrayPathToObject(root[p], parts, value)
}
This function utilizes the fact that objects are pass-by-reference to recursively traverse through the object starting at its root until setting the desired value.
You can add error-handling and other such concerns as necessary for your use.
#Meggan Naude, toJson function copies json object to reference obj for provided keys and value.
const p = { "test.subtest.pass" : "test passed", "test.subtest.fail" : "test failed" };
const result = {} ;
const toJson = (obj, keys, value) => {
if (keys?.length === 1) {
obj[keys[0]] = value;
return obj
} else {
const k = keys.splice(0, 1)
if (k in obj) {
toJson(obj[k], keys, value)
} else {
obj[k] = {};
toJson(obj[k], keys, value)
}
return obj
}
}
Object.keys(p).forEach(key => toJson(result, key.split('.'), p[key]))
console.log(result);

Filter letter by letter on Array Angular

I am trying to filter letter by letter on an array as below
MyJSON
"mainArr":[
{
"data":false,
"myArr":[
{
"myNumber": 12345,
},
{
"myNumber": 8961,
}
]
}
]
And here is code which I am drafting below for search but unable to pick object based on letter keypress or key down or ion-input
if (filterVal && filterVal.trim() !== '') {
this.myArray = this.myArray.filter(function (item) {
const results: any = [];
const obj = item.mainArr[0];
if (_.has(obj, 'myArr')) {
console.log(obj.myArr.indexOf(filterVal));
for (let i = 0; i < obj.myArr.length; i++) {
if (obj.myArr.indexOf(filterVal) !== -1)
return results.push(obj.myArr[i]);
}
}
}
});
}
Refered URL
Tried another way of implementing it, but backspace is not re-binding to original array
let results: any = [];
events.subscribe('filterSearch', (filterVal: string) => {
if (filterVal && filterVal.trim() !== '') {
results = Object.assign(this.allEventsSorted.filter(function (item: any): any {
const fltDty = item.mainArr[0];
if (_.has(fltDty, 'myArr')) {
return _.some(
item.mainArr[0].myArr,
function (tag): any {
return _.startsWith(tag.myNumber, filterVal);
// return _.includes(tag.myNumber, filterVal);
}
);
}
}));
this.allEventsSorted = results;
}
});

traversing a json for empty array value

i have a below json
{
"loanDetails": [
{
"vehicleDetail": {
"RCBookImageReferences": {
"imagePathReferences": [
{
}
]
}
},
"chargeDetails": [
{
}
],
"commissionDetails": [
{
}
],
"disbursementDetails": [
{
}
]
}
]
}
in the above json i need to traverse every key and if i find it emty then set the parent as empty array ie the output should be as below
{"loanDetails":[]}
i used the code below
function isEmpty(obj) {
for(var prop in obj) {
if(obj.hasOwnProperty(prop))
return false;
}
return true;
}
But it did not give me the expected result.I'm stuck here any help will be much helpful.
The function clean takes an object and loops over its keys, calling clean recursively
on each object-valued property.
If the result of cleaning is an empty object, delete the key in question.
If the object itself turns out to be empty, return undefined, triggering deletion of the property holding that object at the higher level.
function clean(obj) {
var isEmpty = true;
for (var key in obj) {
var val = obj[key];
if (val === null || typeof val !== 'object' || (obj[key] = clean(val))) {
isEmpty = false;
} else {
delete obj[key];
}
}
return isEmpty ? undefined : obj;
}
>> a = { x: 1, b: { y: [] }, c: { d: { } } }
>> clean(a)
<< Object {x: 1}
This should make it recursive. With two solutions.
Solution 1: empty test function
var boolValue = true;
for(var prop in obj) {
if(obj.hasOwnProperty(prop) && typeof obj[prop] === 'object')
{
boolValue = recursiveIsEmpty(obj[prop]);
}
else
{
return false;
}
}
return boolValue ;
//test and set empty string
recursiveIsEmpty(jsonDataObj['loanDetails']) ? jsonDataObj['loanDetails'] = [] : null;
Solution 2 recursive empty function that empties parent obj
function recursiveIsEmpty(obj) {
var boolValue = true;
for(var prop in obj) {
if(obj.hasOwnProperty(prop) && typeof obj[prop] === 'object')
{
boolValue = recursiveIsEmpty(obj[prop]);
if (boolValue)
{
delete obj[prop]; //an object is empty. Delete from parent;
}
}
else
{
return false;
}
}
return boolValue; //returns an empty object
}
recursiveIsEmpty(jsonDataObj['loanDetails']) //returns jsonDataObj['loanDetails'] = [];
This checks if obj has a property that is an object. If so load that object and check it's properties. If not return false, because that will be string or number and that confirms the object is not empty.
Your JSON-string is not valid. When corrected, you can use a reviver function parameter (see MDN) to remove 'empty' arrays (aka properties with criteria you specify).
To be clear, the reviver function takes care of the traversing on all levels of the parsed object. If it returns undefined the property is removed from the object. The reviver used in the snippet thus removes all properties containing arrays with empty objects, or empty arrays.
The snippet demonstrates this.
// json string corrected
var foo = '{"loanDetails": [{"vehicleDetail": {"RCBookImageReferences": '+
'{"imagePathReferences": [{}]}}, "chargeDetails": [{}],'+
'"commissionDetails": [{}],"disbursementDetails": [{}]}]}';
// parse it, using reviver parameter
var fooparsed = JSON.parse( foo,
function (key, value) { //<= reviver here
return (value.length && value.length == 1 &&
value[0] instanceof Object &&
Object.keys(value[0]).length == 0) ||
value instanceof Array && !value.length
? undefined : value;
}
);
// print
Helpers.log2Screen( Object.print(fooparsed) );
<script src="http://kooiinc.github.io/JSHelpers/Helpers-min.js"></script>
if you are doing this using ajax then you should go with seriallizing the jason array using javascript.
at the time of passing data through json
data: "your data",
use this
data:$(form).serialize(),
it will pass all the key of that form which you are passing ,
if you want to see its result the try to print it on console

Knockoutjs: Remove/add element from array nested in viewmodel

I want to remove and add an element from an array which is nested in a ko.observable object. I'm using the ko.mapping utility to map json data to my viewmodel. Inside the json data i have an array and it is this array that i want to remove and add an element from.
The add and remove functions are call from HTML bindings.
See my current code for doing this. It is not elegant at all, i know that, that is why i'm asking for help. How do i do see smarter?
function BaseViewModel() {
var self = this;
self.newItem = null;
self.selectedItem = ko.observable();
self.getNewItem = function () {
return self.newCleanItem(self.newItem);
}
self.read = function (search, callback) {
self.baseService.read(search, callback);
}
self.readCallback = function (data) {
if (self.newItem == null)
self.newItem = data;
self.selectedItem(data);
showInputContainer();
}
self.addLog = function () {
var item = new self.getNewItem();
var newItem = item.tLogs[0];
var currentSelectedItem = ko.mapping.toJS(self.selectedItem);
currentSelectedItem.tLogs.push(newItem);
self.selectedItem(currentSelectedItem);
showInputContainer(activeTab);
};
self.removeLog = function (item) {
var currentSelectedItem = ko.mapping.toJS(self.selectedItem);
currentSelectedItem.tLogs.pop(item);
vm.selectedItem(currentSelectedItem);
showInputContainer();
}
self.newCleanItem = function (data) {
for (var d in data) {
if (Object.prototype.toString.call(data[d]) === '[object Array]') {
var array = data[d];
for (var item in array) {
if (framework.baseFunctions().isNumeric(item)) {
for (var i in array[item]) {
array[i] = "";
}
}
}
data[d] = array;
}
else {
data[d] = "";
}
}
return data;
}
}
My jsondata could look that this:
jsondata = {
caseName: "test",
caseDescription: "This is a test",
tLogs: [
{
name: "log1",
date: "2013-03-19"
},
{
name: "log2",
date: "2013-02-02"
}
]
}

Find an element in an array recursively

I have an array of objects. Every object in the array has an id and an item property that is an array containing other object. I need to be able to find an element in an array by id. Here is a sample of what I have done so far, but the recursive function is always returning undefined.
How can I quit the function and return the item when I have called the function recursively several times?
$(function () {
var treeDataSource = [{
id: 1,
Name: "Test1",
items: [{
id: 2,
Name: "Test2",
items: [{
id: 3,
Name: "Test3"
}]
}]
}];
var getSubMenuItem = function (subMenuItems, id) {
if (subMenuItems && subMenuItems.length > 0) {
for (var i = 0; i < subMenuItems.length; i++) {
var item;
if (subMenuItems[i].Id == id) {
item = subMenuItems[i];
return item;
};
getSubMenuItem(subMenuItems[i].items, id);
};
};
};
var searchedItem = getSubMenuItem(treeDataSource, 3);
alert(searchedItem.id);
});
jsFiddle
You should replace
getSubMenuItem(subMenuItems[i].items, id);
with
var found = getSubMenuItem(subMenuItems[i].items, id);
if (found) return found;
in order to return the element when it is found.
And be careful with the name of the properties, javascript is case sensitive, so you must also replace
if (subMenuItems[i].Id == id) {
with
if (subMenuItems[i].id == id) {
Demonstration
Final (cleaned) code :
var getSubMenuItem = function (subMenuItems, id) {
if (subMenuItems) {
for (var i = 0; i < subMenuItems.length; i++) {
if (subMenuItems[i].id == id) {
return subMenuItems[i];
}
var found = getSubMenuItem(subMenuItems[i].items, id);
if (found) return found;
}
}
};
I know its late but here is a more generic approach
Array.prototype.findRecursive = function(predicate, childrenPropertyName){
if(!childrenPropertyName){
throw "findRecursive requires parameter `childrenPropertyName`";
}
let array = [];
array = this;
let initialFind = array.find(predicate);
let elementsWithChildren = array.filter(x=>x[childrenPropertyName]);
if(initialFind){
return initialFind;
}else if(elementsWithChildren.length){
let childElements = [];
elementsWithChildren.forEach(x=>{
childElements.push(...x[childrenPropertyName]);
});
return childElements.findRecursive(predicate, childrenPropertyName);
}else{
return undefined;
}
}
to use it:
var array = [<lets say an array of students who has their own students>];
var joe = array.findRecursive(x=>x.Name=="Joe", "students");
and if you want filter instead of find
Array.prototype.filterRecursive = function(predicate, childProperty){
let filterResults = [];
let filterAndPushResults = (arrayToFilter)=>{
let elementsWithChildren = arrayToFilter.filter(x=>x[childProperty]);
let filtered = arrayToFilter.filter(predicate);
filterResults.push(...filtered);
if(elementsWithChildren.length){
let childElements = [];
elementsWithChildren.forEach(x=>{
childElements.push(...x[childProperty]);
});
filterAndPushResults(childElements);
}
};
filterAndPushResults(this);
return filterResults;
}
