QUESTION

Why do I receive this ReferenceError?

Asked 2022-Mar-25 at 11:34

ReferenceError: array is not defined

I've been trying to add click event listeners to multiple buttons but when I run it in the console it gives me the referenceError above.

Below is my javascript code:

let buttons = document.querySelectorAll(".save");
console.log(array);

buttons.forEach((button) => {
  button.addEventListener("click", () => {
    alert("forEach worked");
  });
});

I have looked at other questions on StackOverFlow for an answer, but they basically all say that I should put the tag at that the end of the html body so that the html can load before. I tried this and it doesn't work still.

Here is my html code for reference:

<body>
    <div class="Container1">
        <li class="dropdown">
              <ul class="dropdown-menu dropdown-menu--animated">

        <h1 class="trails-head">Trails</h1>
        <h2 class="trails-h2">One of the things that makes hiking so exciting is endless options of trails you can take,each each is a very different experience. Hiking is also an incredible way to keep fit while discoering new places. Additionally it is a very social activity and is an amazing activity for friends, work colleagues or any other group.</h2>
        <h3 class="trails-h3">Different Terrain</h3>
        <h4 class="trails-h4">With different terrain comes a different experience. But it also comes with different preparations and equiptment. With a dry and rocky hike it is better to wear good hiking boots with decent grip. You could also bring a walking stick to help with stability in the more difficult patches of the hike. If you are planning hiking in a snowy and frozen climate it is of course better to wear hiking boots with ice grip or spikes. It is of course going to be colder and then it is smart to pack some warm but lightweight clothes.</h4>

The problem is console.logging an array object, that doesn't exist. After deleting the line, ReferenceError shouldn't be a problem.
