我如何使用 javascript 在正确的位置创建 html

Question

我尝试使用 javascript 创建 HTML 个元素，我设法创建了它们，但它们出现在错误的位置。我也在使用 bootstrap.

我现在遇到的问题是如何在页面的特定位置创建 html 元素。

在这种情况下，在我的模态主体下 div-> 容器流体 div -> 新行 div

let a = 1;

//function to create text area and date picker with unique id
function create() {

  let input = document.createElement("input");
  input.setAttribute('type', 'text');
  input.setAttribute('class', 'form-control');
  input.setAttribute("id", "txt" + a);

  let pickdate = document.createElement("input");
  pickdate.setAttribute('type', 'date');
  pickdate.setAttribute("id", "pickdate" + a);

  document.body.appendChild(pickdate);
  document.body.appendChild(input);

  a++;
}

.col-md-11 {
  background-color: yellow;
  text-align: right;
  border: 2px solid white;
}

.col-md-2 {
  background-color: lightblue;
  text-align: right;
  border: 2px solid white;
}

.col-md-8 {
  background-color: pink;
}

.col-md-4 {
  background-color: orange;
  text-align: center;
  border: 2px solid white;
}

.col-md-1 {
  background-color: violet;
  align: left;
}

.col-md-5 {
  background-color: grey;
  align: left;
}

.col-md-3 {
  background-color: yellow;
  align: left;
}

.col-md-10 {
  background-color: grey;
}

Answer 1

您正在将元素附加到主体，而不是获取模态节点并像下面那样附加到它。

function create() {

  let input = document.createElement("input");
  input.setAttribute('type', 'text');
  input.setAttribute('class', 'form-control');
  input.setAttribute("id", "txt" + a);

  let pickdate = document.createElement("input");
  pickdate.setAttribute('type', 'date');
  pickdate.setAttribute("id", "pickdate" + a);

  document.querySelector('.modal-body').appendChild(pickdate);
  document.querySelector('.modal-body').appendChild(input);

  a++;
}

Answer 2

在您的创建函数中，首先创建一个新的 div.row。将元素附加到它，最后将该行附加到模式。

let a = 1;

//function to create text area and date picker with unique id
function create() {
  let row = document.createElement('div');
  row.className = 'row';
  let input = document.createElement("input");
  input.setAttribute('type', 'text');
  input.setAttribute('class', 'form-control');
  input.setAttribute("id", "txt" + a);

  let pickdate = document.createElement("input");
  pickdate.setAttribute('type', 'date');
  pickdate.setAttribute("id", "pickdate" + a);

  row.append(pickdate, input);
  document.querySelector('.modal-body .container-fluid').appendChild(row);

  a++;
}
