Why does querySelector only select the first element and how can I fix this?

Question

I am trying to make a calendar where when I click on one of the dates, a form pops up that you have to fill in. I cannot get this to work correctly. The only one I can get to work is the very first "1" date. Everything else does not work and I don't know how to fix it. I have tried rewriting the code and switching to id's, but nothing will work. Any help is appreciated. Thanks!

document.querySelector(".weekdays").addEventListener("click",
  function() {
    document.querySelector(".bg-modal").style.display = "flex";
  });

.bg-modal {
  width: 100%;
  background-color: rgba(0, 0, 0, .7);
  height: 100vh;
  position: fixed;
  z-index: 20;
  display: none;
}

.modal-content {
  width: 30%;
  height: 50%;

  border-radius: 30px;
  background: linear-gradient(to bottom, #2ad6ff, #0069ff);

  border-radius: 20px;
  border: none;
  resize: none;
  font-size: 15px;
  padding-left: 3%;
  padding-top: 2%;
}

  left: 47%;
  top: 85%;
  transform: translateX(-50%);
  background-color: white;

Because that's literally what [`querySelector`](https://developer.mozilla.org/en-US/docs/Web/API/Element/querySelector) is defined to do. If you want all of the matching elements, use [`querySelectorAll`](https://developer.mozilla.org/en-US/docs/Web/API/ParentNode/querySelectorAll). — Heretic Monkey, Mar 05 '19 at 22:49

Use querySelectorAll instead which would return you a list of node. You then have to iterate over then and attach the event handlers.

document.querySelectorAll(".weekdays").forEach(elem => elem.addEventListener("click",
 () => {
    document.querySelector(".bg-modal").style.display = "flex";
  }));

Use querySelectorAll and forEach:

 document.querySelectorAll('.weekdays').forEach(e => e.addEventListener('click', listener)):

querySelector just returns the first element match, querySelectorAll returns all elements that match.

if you want to acces all Class you have to use the querySelectorAll. It's the right way to use class and Javascript like in the doc : https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelectorAll After this you just have to use a forin to parse it.

Try to include the actual code in your answer, not links to code. Links can change and therefore break and become not useful – Blundering Philosopher Mar 05 '19 at 22:53

Because querySelector():

returns the first Element within the document that matches the specified selector, or group of selectors.

If you want to get multiple nodes use querySelectorAll(). It returns a NodeList (it can be iterated just like a normal array).

Why does querySelector only select the first element and how can I fix this?
