Ik heb een pagina waar ik een modal wil oproepen gemaakt mbv het voorbeeld van W3schools

<div class="frame-back">
<p>Text</p>
<button id="myBtn">Klik om verder te lezen</button>
</div>
</div>
<div id="myModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<span class="close">×</span>
<p>Some text in the Modal..</p>
</div>
</div>
<script src="script/modal.js"></script>]
en het script
[ var modal = document.getElementById('myModal');
var btn = document.getElementById("myBtn");
var span = document.getElementsByClassName("close")[0];
btn.onclick = function() {
modal.style.display = "block";
}
span.onclick = function() {
modal.style.display = "none";
}
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
<p>Text</p>
<button id="myBtn">Klik om verder te lezen</button>
</div>
</div>
<div id="myModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<span class="close">×</span>
<p>Some text in the Modal..</p>
</div>
</div>
<script src="script/modal.js"></script>]
en het script
[ var modal = document.getElementById('myModal');
var btn = document.getElementById("myBtn");
var span = document.getElementsByClassName("close")[0];
btn.onclick = function() {
modal.style.display = "block";
}
span.onclick = function() {
modal.style.display = "none";
}
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
Nu wil ik meerdere links die een modal op moeten kunnen roepen op 1 pagina, maar dit werkt niet. (Eén enkele wel)
Ik heb geprobeerd om elk item een eigen nummer en script mee te geven, maar ook dat werkt niet. Hoe kan ik dit oplossen?
Hoe moet ik het shier cript invoeren, zodat het er als script uitziet?
Edit:
Ik heb code-tags geplaatst. Gelieve dit in het vervolg zelf toe te voegen aan je bericht.

Ook zou je een library kunnen inzetten om dit werk wat makkelijker (en cross browser compatible) te maken. Als je van jQuery gebruik maakt is dit volgens mij zo gepiept.
Over de code van @Jan hierboven: dit lijkt mij nogal veel code voor iets relatief simpels? Waarom ken je de data-index attributen dynamisch toe? Deze kun je gewoon in HTML toevoegen?
Ik heb het opgalost via jquery, dat was uiteindelijk eenvoudiger
