This is my code:

var data = {};
data.uuid = uuid;
data.method = "addAddress";

//Other parameters
var par = {};
par.name = "test";
par.surname = "test";

data.concat(par); //doesn't work

var url = myURL;
var result = $.ajax({
    url: url,
    data: data,
    async: false
});

I want to merge two variables array. It is possible to merge this variables?

Answer 1

Variables data and par are objects and there is not concat method in Objects.. So you end up with a TypeError: "data.concat is not a function".

But you can merge the two Objects like this:

var data = {},
    par = {};

data.uuid = 1234;
data.method = 'addAddress';

par.name = 'test';
par.surname = 'test';

Object.keys(par).forEach(k => data[k] = par[k]);

console.log(data);

Note that properties of data that are also in par will be overwritten.
