Input-
{
"0": {
"NAME": "ABC"
},
"1": {
"NAME": "DEF"
},
"2": {
"NAME": "GHI"
},
"3": {
"NAME": "JKL"
},
"4": {
"NAME": "MNO"
}
}
I have this input. I want to get only names in array format like this Output-
["ABC", "DEF", "GHI", "JKL", "MNO"].
try
var arr =[]; for( var i in data ) { if (data.hasOwnProperty(i)){ arr.push(data[i]); } }
Loop over the keys of the object and map its NAME property into an array.
var input = { "0": { "NAME": "ABC" }, "1": { "NAME": "DEF" }, "2": { "NAME": "GHI" }, "3": { "NAME": "JKL" }, "4": { "NAME": "MNO" } };
var result = Object.keys(input).map(function(key){
return input[key].NAME;
});
console.log(result);You will have to loop over object and get values.
var data={0:{NAME:"ABC"},1:{NAME:"DEF"},2:{NAME:"GHI"},3:{NAME:"JKL"},4:{NAME:"MNO"}};
var result = Object.keys(data).map(x=>data[x].NAME)
console.log(result)var data={0:{NAME:"ABC"},1:{NAME:"DEF"},2:{NAME:"GHI"},3:{NAME:"JKL"},4:{NAME:"MNO"}};
var result = [];
for(var key in data){
result.push(data[key].NAME)
}
console.log(result)Because the keys are numeric, or can easily be converted to a number, if you add a length property then you can utilize the built in array iteration methods. You could then use the reduce method to build your array.
Here is an ES6 example:
const input={0:{NAME:"ABC"},1:{NAME:"DEF"},2:{NAME:"GHI"},3:{NAME:"JKL"},4:{NAME:"MNO"}};
input.length = Object.keys(input).length;
const result = Array.prototype.reduce.call(input,
(output, element, index) => ((output[+index] = element.NAME), output), []);
console.log(result); // ["ABC", "DEF", "GHI", "JKL", "MNO"]var result={0:{NAME:"name1"},1:{NAME:"name2"},2:{NAME:"name3"}};
var array = [];
for(var i=0; i<=result.length-1; i++){
array.push(result[i].NAME);
}
console.log(array)
for..in on objects. for will not work as result is a single object and does not have a property length. Also, please add explanation to your answer. Just adding code is not good enough
