JavaScript JavaScript and the DOM (Retiring) Making Changes to the DOM Modifying Elements

I cant make a variable hold two values at the same time!

This code challenge asks me to make inputValue equal the value of the input tag, which I can do easily, but then it says to make the link stored in the a tag the value of input value, and when I do that it says "Looks like task one is no longer passing". I cant find a way around it!

app.js 
let tinput = document.getElementById("linkName");
let a = document.getElementById("link");
tinput.value = a.value;
let inputValue = tinput.value;
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>

Hi Peter,

The second task says, "Set the text content of the a tag to be the value stored in the variable inputValue."

Your code would look like this:

let tinput = document.getElementById("linkName"); 
let a = document.getElementById("link"); 
let inputValue = tinput.value; 
a.textContent = inputValue;

The 4th line is what you're missing. You're setting the textContent of a (a tag) to be the value you stored in inputValue.

Cheers,

Yeah, that makes sense now that you point it out, Thanks :)

I think (my payment is overdue, I can't see the challenge!) what they want is for you to take inputValue and make the inner text of the link read as that value. So something like this:

let tinput = document.getElementById("linkName");
let a = document.getElementById("link");
let inputValue = tinput.value;
a.innerText = inputValue;

Your concept was right, but I was supposed to set it to textContent instead of innerText, Thanks for your help though!

I was able to get both tasks to pass with these two lines of code:

let inputValue = linkName.value;
link.textContent = inputValue;
