I think, I have solved the problem.
New Script:
<script>
// Get the modal
var modal_1 = document.getElementById("myModal_1");
// Get the button that opens the modal
var btn_1 = document.getElementById("myBtn_1");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close_1")[0];
// When the user clicks the button, open the modal
btn_1.onclick = function() {
modal_1.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal_1.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal_1) {
modal_1.style.display = "none";
}
}
</script>
<script>
// Get the modal
var modal_2 = document.getElementById("myModal_2");
// Get the button that opens the modal
var btn_2 = document.getElementById("myBtn_2");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close_2")[0];
// When the user clicks the button, open the modal
btn_2.onclick = function() {
modal_2.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal_2.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.addEventListener("click", function(event) {
if (event.target == modal_2) {
modal_2.style.display = "none";
}
})
</script>
