insertadjacentelement in javascript code example

Example 1: Uncaught TypeError: Failed to execute 'insertAdjacentElement' on 'Element': parameter 2 is not of type 'Element'

The second parameter of insertAdjacentElement() should be a html object.
The trick below works :)


var htmlString = `<div class="item clearfix" id="income-${obj.id}">
            <div class="item__description">${obj.descripiton}</div>
            <div class="right clearfix">
                <div class="item__value">${obj.value}</div>
                <div class="item__delete">
                    <button class="item__delete--btn"><i class="ion-ios-close-outline"></i></button>
                </div>
            </div>
        </div>`
 var htmlObject = document.createElement('div');
 htmlObject.innerHTML=htmlString;
 document.querySelector(".income__list").insertAdjacentElement('beforeend', htmlObject);

Example 2: HTML DOM insertAdjacentElement() Method

<!DOCTYPE html>
<html>
<body>

<h1>HTML DOM insertAdjacentElement() Method</h1>

<p>This method inserts a specified element, into a specified position.</p>

<span style="color:red">My span</span>

<h2 id="myH2">My Header</h2>

<p>Click the button to insert the red span after the header:</p>

<button onclick="myFunction()">Move span</button>

<script>
function myFunction() {
  var s = document.getElementsByTagName("span")[0];
  var h = document.getElementById("myH2");
  h.insertAdjacentElement("afterend", s);
}
</script>

</body>
</html>
