I have an array with some ids, the return object of my request to the WebService is as shown in code snippet number 1.

I would like to know if there is any way via jQuery, to just extract the values and leave my JSON as shown by the object of the second code snippet:

How are you?

   [{
            "id": "1"
        }, {
            "id": "2"
        }, {
            "id": "3"
        }, {
            "id": "4"
        }, {
            "id": "5"
        }]

How I wish you were:

["1","2","3","4","5"]

You can use the Array.map method to extract only ids .

Example:

let dados = [
    { "id": "1" },
    { "id": "2" },
    { "id": "3" },
    { "id": "4" },
    { "id": "5" }
];

let ids = dados.map(item => item.id);

console.log(ids);

If you can not use arrow functions , another example:

var dados = [
    { "id": "1" },
    { "id": "2" },
    { "id": "3" },
    { "id": "4" },
    { "id": "5" }
];

var ids = dados.map(function(item) {
    return item.id;
});

console.log(ids);
