how to make array of object using an array? - javascript

I have one array
var ar=['aa','cc','po']
I want to push objects in new array after checking the value of given array .In other words
I have these given conditions
var ar=['aa','cc','po']
var arr =[{name:"po"},{name:'aa'},{name:'cc'}];
Expected Output in new Array
[{name:'aa'},{name:'cc'},{name:"po"}]
As "aa" in in 0 index then I added object whose name property aa.
I try like this .but I used two for look .is there any simple way to do this
FIDDLE
var newArr=[];
for(var i=0;i<ar.length ;i++){
var text =ar[i];
for(var j=0;j<arr.length ;j++){
var obj =arr[j];
console.log(obj.name);
/*if(obj.name===text){
newArr.push(obj);
}*/
}
}
console.log(newArr);

This is a proposal in two part, first build an object with the reference to the items of arr and the create a new array with the given items of ar.
var ar = ['aa', 'cc', 'po'],
arr = [{ name: "po" }, { name: 'aa' }, { name: 'cc' }],
object = Object.create(null),
result = [];
arr.forEach(function (a) {
object[a.name] = a;
});
ar.forEach(function (a) {
object[a] && result.push(object[a]);
});
document.write('<pre>' + JSON.stringify(result, 0, 4) + '</pre>');

Using forEach iterator and generate object reference based on name and then generate result array using map()
var ar = ['aa', 'cc', 'po']
var arr = [{
name: "po"
}, {
name: 'aa'
}, {
name: 'cc'
}];
var ref = {};
// generating object reference with name property
arr.forEach(function(v) {
ref[v.name] = v;
});
// generating result array
// or you can use forEach as #NinaScholz answer
var res = ar.map(function(v) {
return ref[v];
}).filter(function(v) { // use filter to avoid null values , in case of missing elements
return v != null;
});
document.write('<pre>' + JSON.stringify(res, null, 3) + '</pre>');

Try this:
function convert(source) {
var
obj = [],
i;
for (i = 0; i < source.length; ++i) {
obj.push({name: source[i]});
}
return obj;
}
convert(['aa', 'bb', 'cc']); // [{name:'aa'},{name:'bb'},{name:'cc'}]

This would work if you want to assign values from array in sequence:
var ar=['aa','cc','po']
var arr =[{name:"po"},{name:'aa'},{name:'cc'}];
arr.map(function(obj,key){
obj.name = ar[key];
});
console.log(arr);

Do like this
var ar = ['aa', 'cc', 'po']
var arr = [{ name: "po"}, { name: 'aa'}, { name: 'cc'}];
$.each(ar, function(i, v) {
arr[i].name = v;
});
console.log(arr)
Fiddle

var array=['a','b','c'];
var arrayObj=[];
for(var i=0;i<array.length;i++){
var obj={};
obj.name=array[i];
arrayObj.push(obj);
}
console.log(JSON.stringify(arrayObj));
Output:
[{"name":"a"},{"name":"b"},{"name":"c"}]

I guess this is one very functional way of doing this job with no more than an assignment line. However Anoop Joshi's answer is more elegant provided that the ar array is shorter than equal to in length to the arr array.
var arr = ['aa','cc','po'],
ar = [{name:"po"},{name:'aa'},{name:'cc'}],
res = arr.map(e => ar[ar.findIndex(f => f.name == e)]);
document.write("<pre>" + JSON.stringify(res) + "</pre>");

array indexOf with objects?

I know we can match array values with indexOf in JavaScript. If it matches it wont return -1.
var test = [
1, 2, 3
]
// Returns 2
test.indexOf(3);
Is there a way to match objects? For example?
var test = [
{
name: 'Josh'
}
]
// Would ideally return 0, but of course it's -1.
test.indexOf({ name: 'Josh' });
Since the two objects are distinct (though perhaps equivalent), you can't use indexOf.
You can use findIndex with a callback, and handle the matching based on the properties you want. For instance, to match on all enumerable props:
var target = {name: 'Josh'};
var targetKeys = Object.keys(target);
var index = test.findIndex(function(entry) {
var keys = Object.keys(entry);
return keys.length == targetKeys.length && keys.every(function(key) {
return target.hasOwnProperty(key) && entry[key] === target[key];
});
});
Example:
var test = [
{
name: 'Josh'
}
];
var target = {name: 'Josh'};
var targetKeys = Object.keys(target);
var index = test.findIndex(function(entry) {
var keys = Object.keys(entry);
return keys.length == targetKeys.length && keys.every(function(key) {
return target.hasOwnProperty(key) && entry[key] === target[key];
});
});
console.log(index);
Note that findIndex was added in ES2015, but is fully polyfillable.
Nope, you can't and the explanation is simple. Despite you use the same object literal, two different objects are created. So test would have another reference for the mentioned object if you compare it with the reference you are looking for in indexOf.
This is kind of custom indexOf function. The code just iterates through the items in the object's array and finds the name property of each and then tests for the name you're looking for. Testing for 'Josh' returns 0 and testing for 'Kate' returns 1. Testing for 'Jim' returns -1.
var test = [
{
name: 'Josh'
},
{
name: 'Kate'
}
]
myIndexOf('Kate')
function myIndexOf(name) {
testName = name;
for (var i = 0; i < test.length; i++) {
if(test[i].hasOwnProperty('name')) {
if(test[i].name === testName) {
console.log('name: ' + test[i].name + ' index: ' + i);
return i;
}
}
}
return -1;
}
You can loop on array and then look for what you want
var test = [{ name: 'Josh' }]
const Myname = test.map((item) => { return item.name; }).indexOf("Josh")

How to create a json data using two arrays and return it to ajax

key:[id,name,address]
value:[7,John,NewYork]
I wish to create a json data like{"id": 7, "name": "John", "address": "NewYork"} using for(...){...},
and then return it to ajax
$.ajax({
//what kind of format should json data be here?
data:??json data??,
dataType: 'json',
});
Please help me
To the first part of your question:
You could use Array#forEach() and assign all properties with the correspondet value.
var key = ['id', 'name', 'address'],
value = [7, 'John', 'New York'],
object = {};
key.forEach(function (k, i) {
object[k] = value[i];
})
document.write('<pre>' + JSON.stringify(object, 0, 4) + '</pre>');
You could:
iterate through both arrays...
...add the 1st array element to an empty obj as a key...
...and assign the 2nd array element to the 1st array element as it's value.
Each iteration will be paired as key/value when stringified as a JSON.
I'm surprised it actually worked, take a look at the demo below:
SNIPPET
var x = ['id', 'name', 'address'];
var y = [7, 'John', 'NewYork'];
function arrMerge(k, v) {
var obj = {};
for (var i = 0; i < k.length; i++) {
obj[k[i]] = v[i];
}
return obj;
}
var z = arrMerge(x, y);
var json = JSON.stringify(z);
console.log(json);
You can write a general function that zips two arrays together into an object if they're of equal length (also assuming they're in the correct order).
function zip(arr1, arr2) {
if (arr1.length !== arr2.length) return false;
const obj = {};
for (let i = 0; i < arr1.length; i++) {
const key = arr1[i];
obj[key] = arr2[i];
}
return obj;
}
zip(arr1, arr2); // { id: 7, name: "John", address: "NewYork" }
DEMO
You can then use that object as the value of data in your AJAX process.
data
Type: PlainObject or String or Array
Data to be sent to the server. It is converted to a query string, if not already a string.
jQuery documentation
I guess unlike forEach, since it returns the result, Array.prototype.reduce() comes very handy for these operations. You can even use it at the stage of declaring your JSON data (jData here).
var key = ['id', 'name', 'address'],
value = [7, 'John', 'New York'],
jData = JSON.stringify(key.reduce((p,c,i) => {p[c] = value[i]; return p},{}));
document.write("<pre>" + jData + "</pre>");

From js object to array [duplicate]

My application creates a JavaScript object, like the following:
myObj= {1:[Array-Data], 2:[Array-Data]}
But I need this object as an array.
array[1]:[Array-Data]
array[2]:[Array-Data]
So I tried to convert this object to an array by iterating with $.each through the object and adding the element to an array:
x=[]
$.each(myObj, function(i,n) {
x.push(n);});
Is there an better way to convert an object to an array or maybe a function?
If you are looking for a functional approach:
var obj = {1: 11, 2: 22};
var arr = Object.keys(obj).map(function (key) { return obj[key]; });
Results in:
[11, 22]
The same with an ES6 arrow function:
Object.keys(obj).map(key => obj[key])
With ES7 you will be able to use Object.values instead (more information):
var arr = Object.values(obj);
Or if you are already using Underscore/Lo-Dash:
var arr = _.values(obj)
var myObj = {
1: [1, 2, 3],
2: [4, 5, 6]
};
var array = $.map(myObj, function(value, index) {
return [value];
});
console.log(array);
Output:
[[1, 2, 3], [4, 5, 6]]
Simply do
Object.values(obj);
That's all!
I think you can use for in but checking if the property is not inerithed
myObj= {1:[Array-Data], 2:[Array-Data]}
var arr =[];
for( var i in myObj ) {
if (myObj.hasOwnProperty(i)){
arr.push(myObj[i]);
}
}
EDIT - if you want you could also keep the indexes of your object, but you have to check if they are numeric (and you get undefined values for missing indexes:
function isNumber(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
myObj= {1:[1,2], 2:[3,4]}
var arr =[];
for( var i in myObj ) {
if (myObj.hasOwnProperty(i)){
if (isNumber(i)){
arr[i] = myObj[i];
}else{
arr.push(myObj[i]);
}
}
}
If you know the maximum index in you object you can do the following:
var myObj = {
1: ['c', 'd'],
2: ['a', 'b']
},
myArr;
myObj.length = 3; //max index + 1
myArr = Array.prototype.slice.apply(myObj);
console.log(myArr); //[undefined, ['c', 'd'], ['a', 'b']]
Since ES5 Object.keys() returns an array containing the properties defined directly on an object (excluding properties defined in the prototype chain):
Object.keys(yourObject).map(function(key){ return yourObject[key] });
ES6 takes it one step further with arrow functions:
Object.keys(yourObject).map(key => yourObject[key]);
Nowadays, there is a simple way to do this : Object.values().
var myObj = {
1: [1, 2, 3],
2: [4, 5, 6]
};
console.log(Object.values(myObj));
Output:
[[1, 2, 3], [4, 5, 6]]
This doesn't required jQuery, it's been defined in ECMAScript 2017.
It's supported by every modern browser (forget IE).
The best method would be using a javascript -only function:
var myArr = Array.prototype.slice.call(myObj, 0);
x = [];
for( var i in myObj ) {
x[i] = myObj[i];
}
ECMASCRIPT 5:
Object.keys(myObj).map(function(x) { return myObj[x]; })
ECMASCRIPT 2015 or ES6:
Object.keys(myObj).map(x => myObj[x])
How about jQuery.makeArray(obj)
This is how I did it in my app.
ES8 way made easy:
The official documentation
const obj = { x: 'xxx', y: 1 };
let arr = Object.values(obj); // ['xxx', 1]
console.log(arr);
The solving is very simple
var my_obj = {1:[Array-Data], 2:[Array-Data]}
Object.keys(my_obj).map(function(property_name){
return my_obj[property_name];
});
Fiddle Demo
Extension to answer of bjornd .
var myObj = {
1: [1, [2], 3],
2: [4, 5, [6]]
}, count = 0,
i;
//count the JavaScript object length supporting IE < 9 also
for (i in myObj) {
if (myObj.hasOwnProperty(i)) {
count++;
}
}
//count = Object.keys(myObj).length;// but not support IE < 9
myObj.length = count + 1; //max index + 1
myArr = Array.prototype.slice.apply(myObj);
console.log(myArr);
Reference
Array.prototype.slice()
Function.prototype.apply()
Object.prototype.hasOwnProperty()
Object.keys()
If you want to keep the name of the object's properties as values. Example:
var fields = {
Name: { type: 'string', maxLength: 50 },
Age: { type: 'number', minValue: 0 }
}
Use Object.keys(), Array.map() and Object.assign():
var columns = Object.keys( fields ).map( p => Object.assign( fields[p], {field:p} ) )
Result:
[ { field: 'Name', type: 'string', maxLength: 50 },
{ field: 'Age', type: 'number', minValue: 0 } ]
Explanation:
Object.keys() enumerates all the properties of the source ; .map() applies the => function to each property and returns an Array ; Object.assign() merges name and value for each property.
I made a custom function:
Object.prototype.toArray=function(){
var arr=new Array();
for( var i in this ) {
if (this.hasOwnProperty(i)){
arr.push(this[i]);
}
}
return arr;
};
After some tests, here is a general object to array function convertor:
You have the object:
var obj = {
some_key_1: "some_value_1"
some_key_2: "some_value_2"
};
The function:
function ObjectToArray(o)
{
var k = Object.getOwnPropertyNames(o);
var v = Object.values(o);
var c = function(l)
{
this.k = [];
this.v = [];
this.length = l;
};
var r = new c(k.length);
for (var i = 0; i < k.length; i++)
{
r.k[i] = k[i];
r.v[i] = v[i];
}
return r;
}
Function Use:
var arr = ObjectToArray(obj);
You Get:
arr {
key: [
"some_key_1",
"some_key_2"
],
value: [
"some_value_1",
"some_value_2"
],
length: 2
}
So then you can reach all keys & values like:
for (var i = 0; i < arr.length; i++)
{
console.log(arr.key[i] + " = " + arr.value[i]);
}
Result in console:
some_key_1 = some_value_1
some_key_2 = some_value_2
Edit:
Or in prototype form:
Object.prototype.objectToArray = function()
{
if (
typeof this != 'object' ||
typeof this.length != "undefined"
) {
return false;
}
var k = Object.getOwnPropertyNames(this);
var v = Object.values(this);
var c = function(l)
{
this.k = [];
this.v = [];
this.length = l;
};
var r = new c(k.length);
for (var i = 0; i < k.length; i++)
{
r.k[i] = k[i];
r.v[i] = v[i];
}
return r;
};
And then use like:
console.log(obj.objectToArray);
You can create a simple function to do the conversion from object to array, something like this can do the job for you using pure javascript:
var objectToArray = function(obj) {
var arr = [];
if ('object' !== typeof obj || 'undefined' === typeof obj || Array.isArray(obj)) {
return obj;
} else {
Object.keys(obj).map(x=>arr.push(obj[x]));
}
return arr;
};
or this one:
var objectToArray = function(obj) {
var arr =[];
for(let o in obj) {
if (obj.hasOwnProperty(o)) {
arr.push(obj[o]);
}
}
return arr;
};
and call and use the function as below:
var obj = {1:'a', 2:'b', 3:'c', 4:'d', 5:'e'};
objectToArray(obj); // return ["a", "b", "c", "d", "e"]
Also in the future we will have something called Object.values(obj), similar to Object.keys(obj) which will return all properties for you as an array, but not supported in many browsers yet...

How to convert an array of objects into a mapped object in JavaScript?

How can I convert something like initialArray array of JSON objects into finalObject map?
var initialArray = [
{ id:'id1', name:'name1' },
{ id:'id2', name:'name2' },
{ id:'id3', name:'name3' },
{ id:'id4', name:'name4' }
];
var finalObject = {
'id1':'name1',
'id2':'name2',
'id3':'name3',
'id4':'name4'
}
Things to consider:
IDs are strings.
I tried for in loop - couldn't make it to work - http://jsfiddle.net/5af9R/23/
Any ideas?
You need to operate on the objects in your array, not strings containing their indexes in the array.
You should also use a regular for loop to iterate over an array.
Your JSFiddle, fixed:
var x = [ {id:'1', img:'img1'}, {id:'2', img:'img2'}, {id:'3', img:'img3'} ];
var resp = {};
for( var i = 0 ; i < x.length ; i++ ){
var obj = x[i];
resp[obj.id] = obj.img;
}
document.write( JSON.stringify(resp, undefined, 2) );
​
DEMO
You can loop over the array, and for each object, add a new property to finalObject whose property name is the id, and whose value is the name.
var finalObject = {};
for (var i = 0, max = initialArray.length; i < max; i++)
finalObject[initialArray[i].id] = initialArray[i].name;
resp[key.id] = key.img;
You correctly call it key. But you need a value;
resp[x[key].id] = x[key].img;
var finalObject = initialArray.reduce(function(ret, obj){
ret[obj.id] = obj.name;
return ret;
}, {});
This solution is specific to the property names for the specific question, but Array.prototype.reduce is a function I use all the time for any sort of array iteration that requires a non-array result.
You're not using For In correctly jsFiddle
var x = [ {id:'1', img:'img1'}, {id:'2', img:'img2'}, {id:'3', img:'img3'} ];
var resp = {};
for( var key in x ){
resp['id' + x[key].id] = x[key].img;
}
document.write( JSON.stringify(resp, undefined, 2) );
​
for (var i=0; i<x.length; i++) {
var id = 'id' + x[i].id;
var img = x[i].img;
resp[id] = img;
}
if i have understood correctly you can do something like
var x =' [ {"id":"1", "img":"img1"}, {"id":"2", "img":"img2"}, {"id":"3", "img":"img3"}]';
var resp = {};
var json = $.parseJSON(x);
$(json).each(function(i,v){
resp[v.id]=v.img;
});
console.log( resp);
DEMO
you talked about json but in the fiddle you provided there was no json even jquery was not added as a resource so i made some assumptions
Today I was on the same question and I didn't find an answer here, except the answer of #adam-rackis.
The way I found is :
var initialArray = [
{ id:'id1', name:'name1' },
{ id:'id2', name:'name2' },
{ id:'id3', name:'name3' },
{ id:'id4', name:'name4' }
],
finalObject = {};
$.each(initialArray, function(k,v) {
finalObject[v.name] = v.value;
});

}
return r;
}
Function Use:
var arr = ObjectToArray(obj);
You Get:
arr {
key: [
"some_key_1",
"some_key_2"
],
value: [
"some_value_1",
"some_value_2"
],
length: 2
}
So then you can reach all keys & values like:
for (var i = 0; i < arr.length; i++)
{
console.log(arr.key[i] + " = " + arr.value[i]);
}
Result in console:
some_key_1 = some_value_1
some_key_2 = some_value_2
Edit:
Or in prototype form:
Object.prototype.objectToArray = function()
{
if (
typeof this != 'object' ||
typeof this.length != "undefined"
) {
return false;
}
var k = Object.getOwnPropertyNames(this);
var v = Object.values(this);
var c = function(l)
{
this.k = [];
this.v = [];
this.length = l;
};
var r = new c(k.length);
for (var i = 0; i < k.length; i++)
{
r.k[i] = k[i];
r.v[i] = v[i];
}
return r;
};
And then use like:
console.log(obj.objectToArray);
You can create a simple function to do the conversion from object to array, something like this can do the job for you using pure javascript:
var objectToArray = function(obj) {
var arr = [];
if ('object' !== typeof obj || 'undefined' === typeof obj || Array.isArray(obj)) {
return obj;
} else {
Object.keys(obj).map(x=>arr.push(obj[x]));
}
return arr;
};
or this one:
var objectToArray = function(obj) {
var arr =[];
for(let o in obj) {
if (obj.hasOwnProperty(o)) {
arr.push(obj[o]);
}
}
return arr;
};
and call and use the function as below:
var obj = {1:'a', 2:'b', 3:'c', 4:'d', 5:'e'};
objectToArray(obj); // return ["a", "b", "c", "d", "e"]
Also in the future we will have something called Object.values(obj), similar to Object.keys(obj) which will return all properties for you as an array, but not supported in many browsers yet...
