To create a div for each result obtained through a request in an API, the API in use is "https://jsonplaceholder.typicode.com". My intention is to replicate a div "caixaPost" for each obtained result. 

var usuarioId = document.getElementById("usuarioId");
var postId = document.getElementById("postId");
var tituloPost = document.getElementById("tituloPost");
var descricaoPost = document.getElementById("descricaoPost");

var idUsuario = document.getElementById("idUsuario");
document.getElementById("botaoBuscaId").onclick = RequisicaoPorUsuario;

function RequisicaoPorUsuario() {

    var HttpClient = function () {
        this.get = function (aUrl, aCallback) {
            var anHttpRequest = new XMLHttpRequest();
            anHttpRequest.onreadystatechange = function () {
                if (anHttpRequest.readyState == 4 && anHttpRequest.status == 200)
                    aCallback(anHttpRequest.responseText);
            }
            anHttpRequest.open("GET", aUrl, true);
            anHttpRequest.send(null);
        }
    }

    //puxa o id do usuário informado
    var usuarioId = idUsuario.value;

    //da um alert pra verificar se ta puxando corretamente
    alert(usuarioId);

    //concatena a url de busca com o ID do Usuário informado
    var url = "https://jsonplaceholder.typicode.com/posts/?userId="+usuarioId;

    var client = new HttpClient();
    client.get(url, function (response) {
        var response1 = JSON.parse(response);
        console.log(response);

        // exibe todos os dados buscados em uma janela de Alert
        alert(response);

        // Aqui eu desejo criar um laço que crie uma janela de post para cada "resultado" obtido...
    });

Simple as that baby!

notice how the construction is made:

        // Aqui eu desejo criar um laço que crie uma janela de post para cada "resultado" obtido...
        let element = "";
        for (let index = 0; index < response1.length; index++) {
            element = `
              <div>
                <h1>title: ${response1[index].title}</h1>
                <p>body: ${response1[index].body}</p>
              </div>
            `;

          }
   document.getElementById("divResultado").innerHTML = element;


var usuarioId = document.getElementById("usuarioId");
var postId = document.getElementById("postId");
var tituloPost = document.getElementById("tituloPost");
var descricaoPost = document.getElementById("descricaoPost");

var idUsuario = document.getElementById("idUsuario");
document.getElementById("botaoBuscaId").onclick = RequisicaoPorUsuario;

function RequisicaoPorUsuario() {

    var HttpClient = function () {
        this.get = function (aUrl, aCallback) {
            var anHttpRequest = new XMLHttpRequest();
            anHttpRequest.onreadystatechange = function () {
                if (anHttpRequest.readyState == 4 && anHttpRequest.status == 200)
                    aCallback(anHttpRequest.responseText);
            }
            anHttpRequest.open("GET", aUrl, true);
            anHttpRequest.send(null);
        }
    }

    //puxa o id do usuário informado
    var usuarioId = idUsuario.value;

    //concatena a url de busca com o ID do Usuário informado
    var url = "https://jsonplaceholder.typicode.com/posts/?userId="+usuarioId;

    var client = new HttpClient();
    client.get(url, function (response) {
        var response1 = JSON.parse(response);
        console.log(response1[0]);
        
        // Aqui eu desejo criar um laço que crie uma janela de post para cada "resultado" obtido...

  • Perfect Julio, the path I am looking for is exactly this, but there is still a problem, it ta listing only the last response of the request. From what I’ve observed he’s running a perfect loop, but when writing the next element he ends up writing the first written element.

@Júlio Henrique great answer only that in the section below we must make a slight change to work as expected

        // Aqui eu desejo criar um laço que crie uma janela de post para cada "resultado" obtido...
        let element = ""; // (Antes  let element = "";
        for (let index = 0; index < response1.length; index++) {
            element += ` // (element = `) Dessa forma os itens vão ser acumulados em vez de se sobreescrever
              <div>
                <h1>title: ${response1[index].title}</h1>
                <p>body: ${response1[index].body}</p>
              </div>
            `;

          }

   document.getElementById("divResultado").innerHTML = element;

  • Thanks @Vinicius, one more question, aren’t those "$" dollar bills referring to Jquerry? vetoed the use of Jquerry in the test, if use automatically I am disqualified.

  • If you can’t use jQuery just remove ${} and use response1[index]. * use the character ` before and after concatenating the variable

  • Perfect friend, the syntax went like this, it worked perfectly: var postUserId = Sponse.data[i]. userid; element += &#xA; <div class="caixaUsuarioId">Usuário ID: +postUserId+</div>&#xA; ;

  • Very good friend, success there in your project !
