Store the value of the text input element in the variable inputValue

using const inputValue = document.querySelectorAll(input.id); or const inputValue = document.querySelectorAll(input.linkName);

is not working.

app.js 
let inputValue = document.querySelectorAll('input.linkName');
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>

You have a few issues here:

  • The selector "input.linkName" would target an input element with a class of "linkName", but this element has an ID of "linkName"
  • Since ID's are all unique, you can shorten the selector to just "#linkName"
  • "querySelectorAll" returns a collection but you need a single element. You can use "querySelector" instead.
  • once you've targeted the element, you need to get the "value" property from it
