How do I set the value of my "text" id to my randomThing variable(a random item from my array) when the randomize button is clicked?

<!DOCTYPE html>


    A random item: <input type="text" id="thing"> <button>randomize</button>

    <button id="generate">Generate!</button>
    <p id = "paragraph"></p>
    document.getElementById("generate").onclick = function() {
	document.getElementById("paragraph").innerHTML = "Random thing: " + 

    var thingArray [
    "saucepan", ]
     var randomThing = thingArray[Math.floor(Math.random()*myArray.length)];

Welcome, mad_catter.

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Note: Backticks are not single quotes.


To answer your question:
This line will cause an error:

var randomThing = thingArray[Math.floor(Math.random()*myArray.length)]

Otherwise, what you are asking is odd. You are doing something similar here:

document.getElementById("paragraph").innerHTML = "Random thing: " + 

Could you be more specific as to what you want?

Some of what you are asking is pretty trivial in the Free Code Camp context, so you might find that if you’re not getting the instruction and material you need in your current studies, the FCC curriculum will really help you get started. At a modest guess I’d say investing a 4-5 hours working through the curriculum here will really pay off. You can find the curriculum at

With your current questions, we don’t have enough context to know what you already know or don’t know, so it is impossible to guide you without just telling you the answer (which we won’t do).

It is pretty typical on here for people to share a codepen / / jsfiddle example of what they have tried so that anyone helping has more of an idea of what help is actually helpful.

Please provide some example of what you’ve tried and I’m sure you’ll get more help.

Happy coding :slight_smile:
