I am at a loss, here! I keep failing this challenge and am starting to feel a little down about this.

I feel like I keep following the lessons and yet I am still being quizzed on parts of javascript that I haven't learned yet.

I have just learned the textContent method etc and it seems like a method that would be useful to use here, but I am so wrong.

I am having a very difficult time connecting the dots.

app.js 
let inputValue = document.getElementById('linkName').value

a.textContent = inputValue;
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <div id="content">
            <label>Link Name:</label>
            <input type="text" id="linkName">
            <a id="link" href="https://teamtreehouse.com"></a>
        </div>
        <script src="app.js"></script>
    </body>
</html>

The browser doesn't know what a.textContent means because you haven't declared a variable called "a" yet. You have to target the anchor tag with another .getElementById and store that value in a variable. let inputValue = document.getElementById('linkName').value; let a = document.getElementById('link');

a.textContent = inputValue;

You have the right idea. As Joel said, you should select the <a> tag using one of a few viable methods. Here's one answer:

  • let inputValue = document.getElementById('linkName').value;
  • document.querySelector('a').textContent = inputValue;

In your code, you've set a.textContent = inputValue but you haven't specified what a is.

You can either create the new variable a to get this line of code to work, or instead of creating another variable, do another element selector and update its textContent directly, whichever makes the most sense to you.

Good luck!
