how to add many values to one key in javascript ob

Question

I have an object var obj = {key1: "value1", key2: "value2"}; I want to add multiple values or array of values to key1 or key2 e.g var obj = {key1: "arrayOfValues", key2: "value2"}; is it possible? basically I want to send it to php for process.

Answer 1

You can make objects in two ways.

1. Dot notation
2. Bracket notation

Also you can be define values in array with/without initial size. For scenario one you can do the following in worst case scenario:

var obj = {}
obj.key1 = new Array();
obj.key2 = new Array();
// some codes related to your program
obj.key1.push(value1);
// codes ....
obj.key1.push(value);
// ... same for the rest of values that you want to add to key1 and other key-values

If you want to repeat the above codes in bracket notation, it will be like this

var obj = {}
obj['key1'] = new Array();
obj['key2'] = new Array();
// some codes related to your program
obj['key1'].push(value1);
// codes ....
obj['key1'].push(value);
// ... same for the rest of values that you want to add to key1 and other key-values

With bracket notation, you can use characters e.g 1,3,%, etc. that can't be used with dot notation.

Answer 2

You can just define an array for the property:

var obj = {key1: ["val1", "val2", "val3"], key2: "value2"};

Or, assign it after the fact:

var obj = {key2: "value2"};
obj.key1 = ["val1", "val2", "val3"];
