I'm disabling the share button from inside of photoswipe-ui-default.js
file right now. However I'm wondering whether there is a posibility to do it from outside of that code?
Well I would just disable it through the options listed in the documentation: https://photoswipe.com/documentation/options.html
Otherwise you could do the following:
<script>
var divsToHide = document.getElementsByClassName("pswp__button pswp__button--share"); //divsToHide is an array
for(var i = 0; i < divsToHide.length; i++){
divsToHide[i].style.visibility = "hidden"; // or
divsToHide[i].style.display = "none"; // depending on what you're doing
}
</script>
