Question

Whenever the user hits the "Enter" key, a new element will be generated and added to the bottom of an existing element

I am in need of creating a new element at the end of another element. For instance, let's say I have this element:

<div id="elmtobetrig">Element that should be followed by another element when the user hits enter after this text. <!--Element placeholder--></div>

I have tried the following code:

<div contenteditable="true" id="elmtobetrig"></div>
    <script>document.addEventListener("keyup", function(event) {
    if (event.keyCode === 13) {
      document.querySelector("div#elmtobetrig").createElement("line").innerHTML = "<br> This content should appear at the bottom of the element &nbsp; "
    }
  });</script>

However, it seems that using createElement() on a specific element is not possible... Is there an alternative way to achieve what I am attempting?

Answer №1

It seems like there is an issue with how you are creating the line element.

First, you should utilize the document.createElement method
Next, use .innerHTML to insert text into the element.
Finally, make sure to use .append to add the element to a parent element.

<div contenteditable="true" id="elmtobetrig"></div>
<script>
  document.addEventListener("keyup", function(event) {
    if (event.keyCode === 13) {
      let line = document.createElement("line")
      line.innerHTML = "<br> this should go to the bottom of the element &nbsp; "
      document.querySelector("div#elmtobetrig").append(line)
    }
  });
</script>

Explanation

The createElement() method creates the specified HTML element using the provided tagName, but it does not automatically append the element to any parent.

Remember to create the element, set its attributes, and then ensure that you append it to a parent element. If you skip the appending step, the element will not be added to the DOM correctly.
