It is not possible to update the content of this element using document.getElementById and storing it in a variable

Having trouble with this simple code. Looking for some assistance!

<p id="p">
   Test
</p>

<script>
  var p_tag = document.getElementById("p");

  document.p_tag.innerHTML = "Hey";
</script>

Answer №1

Edit the code snippet to remove "document." before p_tag.

<script>
  var p_tag = document.getElementById("p");
  
  p_tag.innerHTML = "Hey";
</script>

Replace the original code with this:

<script>
  var p_tag = document.getElementById("p");

  p_tag.innerHTML = "Hello";
</script>

Answer №2

It seems like you may be attempting the following:

<p id="p">
   Test
</p>

<script>
  var p_tag = document.getElementById("p");
    p_tag.innerHTML = "Hey";
</script>

Remember, there is no need to duplicate the document since it is already contained in the variable.

Answer №3

var p_tag is a variable that you have already declared as an HTMLElement. It references the existing <p id="p">Test</p>, so make sure to use it correctly:

p_tag.innerHTML = "Hey";

The document object does not interact with your declared variables, so there will not be a p_tag property on document.

You can also simplify this by using:

document.getElementById("p").innerHTML = "Hey";

Answer №4

<p id="p">
   Experiment
</p>

<script>
  var p_element = document.getElementById("p");// locates the html element with id="p"

  This produces an error: document.p_tag.innerHTML = "Hello";
  This is the correct code: p_element.innerHTML = "Hello";// replaces all content inside the element with "Hello"
</script>
