Tell us what’s happening:

I don’t understand why my code is not working.
I am trying to throw an alert when there is no text input.
What is wrong with my code?

Hello, your close but you need a function first with an if statement and a return, right now you’ve kind of combined a click event with the if statement. So a function followed by the the other logic. I guess you could just rearrange things here but you still need a function for the input

<code>goes here</code>

One backtick for a single variable in a sentence.

Keep the triple backticks on a separate line

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.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

I ran into some problem with that, can you give me an example?

Example above, and I’ve edited your post as well.

Triple backticks on a line by themself for a block of code. Single backticks around a single word to show it as code.

Hi thanks for answering, but I found the real problem.
I put the script tag that contains the JS code in the head element before the button, instead I should’ve put it after button, at the end of my HTML.
