I've been researching until I get tired ... what I'd like to do was something like:

var janela = window.open(
    "https://www.google.com/", 
    "_blank"
);
var pesquisa = janela.document.getElementById("lst-ib");
pesquisa.value = "string que quero no input";

But it does not work, I put:

var janela = window.open(
    "https://www.google.com/", 
    "_blank"
);
var pesquisa = janela.document.getElementById("lst-ib");
console.log(pesquisa);

printed null

WHY?

Anyone help me?

    var pesquisa = "string que quero no input";
    var janela = window.open(
        "https://www.google.com/?q=" + pesquisa, 
        "_blank"
    );

See if this helps, the text you put into search will enter as a GET in the google domain and with the field filled, but the search is not done you need to select search.

You need to wait for the window to load so that the element is available and you can change it. You can do this by treating the event onload :

var janela = window.open(
    "https://www.google.com/", 
    "_blank"
);
janela.onload = function(){
    var pesquisa = janela.document.getElementById("lst-ib");
    pesquisa.value = "string que quero no input";
}

If you are testing the location of your machine you will probably take a security permission error, for example "ERR_BLOCKED_BY_CLIENT".
