More than one Modal Boxes on one page

Question

Here I put in 2 buttons where clicking these would popup a modal box.

 <li type="button" id="myBtn" class="w3-hide-small w3-center"><a href="#" class="w3-hover-white">1</a></li>
 <li type="button" id="myBtn2" class="w3-hide-small w3-center"><a href="#" class="w3-hover-white">2</a></li> 

Here's the modal information for week one:

<!-- MODAL INFORMATION FOR WEEK 1  -->
<div id="myModal" class="modal">
  <div class="modal-content">
      <span class="close">×</span>
    <p><h2><font color="black">Week 1</font></h2></p>
    <div class="modal-body">
      <p><font color="black"> ex1</p>
    </div>
  </div>
</div>

Here's the modal information for week two:

<div id="myModal2" class="modal">
  <div class="modal-content">
      <span class="close">×</span>
    <p><h2><font color="black">Week 2</font></h2></p>
      <p><font color="black"> Example 1 </p>
  </div>
</div>

Script:

<script>
// Get the modal
var modal = document.getElementById('myModal');
var modal2 = document.getElementById('myModal2');

// Get the button that opens the modal
var btn = document.getElementById("myBtn");
var btn2 = document.getElementById("myBtn2");

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks the button, open the modal 
btn.onclick = function() {
    modal.style.display = "block";
}

btn2.onclick = function() {
    modal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
    modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
    if (event.target == modal) {
        modal.style.display = "none";
    }
}
</script>

I thought that changing the ID would allow me to treat the modal boxes differently from one another, and also that i'm calling "Btn" and "Btn2" differently.

When I click on 1 and 2, they both open up the same text from week one and 2.

Answer 1

The reason why you are seeing the same content is because you are targeting the same modal:

btn.onclick = function() {
    modal.style.display = "block";
}

btn2.onclick = function() {
    modal.style.display = "block"; <--- should be modal2
}

Answer 2

Try to add a data attribute for the modal. You need to same id in your modal with the same data-target for the button

ex

<!-- MODAL INFORMATION FOR WEEK 1  -->
<div id="myModalA" class="modal">
  <div class="modal-content">
      <span class="close">×</span>
    <p><h2><font color="black">Week 1</font></h2></p>
    <div class="modal-body">
      <p><font color="black"> ex1</p>
    </div>
  </div>
</div>


<div id="myModal2" class="modal">
  <div class="modal-content">
      <span class="close">×</span>
    <p><h2><font color="black">Week 2</font></h2></p>
      <p><font color="black"> Example 1 </p>
  </div>
</div>


 <li type="button" id="myBtn" class="w3-hide-small w3-center" data-target="myModalA"><a href="#" class="w3-hover-white">1</a></li>


 <li type="button" id="myBtn2" class="w3-hide-small w3-center" data-target="myModal2"><a href="#" class="w3-hover-white">2</a></li>
