I am trying to convert an object to an array with pure javascript.
I want to convert this:
[{"itemCode":"Mob-mtr"},{"itemCode":"640-chr"}]
to this:
["Mob-mtr","640-chr","541-mtr"]
i have tried this code:
var arr = Object.keys(obj).map(function (key) {return obj[key]});
and a bunch of other variations with no success.
Any idea how i can convert this object to an array?
You can use the property directly for the return value.
var array = [{ "itemCode": "Mob-mtr" }, { "itemCode": "640-chr" }],
result = array.map(function (a) { return a.itemCode; });
document.write('<pre>' + JSON.stringify(result, 0, 4) + '</pre>');
var data = [{"itemCode":"Mob-mtr"},{"itemCode":"640-chr"}];
var arr=[];
//get all objects in data.
data.forEach(function(obj){
//get all properties of the object.
Object.keys(obj).forEach(function(prop){
arr.push(obj[prop]);
});
});
console.log(arr);
The chosen answer is perfect, but maybe this will help when these properties are not same or unpredictable, who knows.
var oldArray = [
{"itemCode": "Mob-mtr"},
{"itemCode": "640-chr"},
{"itemCode": "541-mtr"}
];
var newArray = [];
oldArray.forEach(function(v) {
newArray.push(v['itemCode']);
});
document.write(newArray);
