引导程序 5：使用 javascript 显示模态

Question

I'm making a neat gallery with bootstrap 5 , and I wondered how I could trigger a bootstrap modal without using "data-bs-..." in my HTML (to avoid duplicating those data- attributes 50 times).

I managed to get a full functionning javascript for the sources, but the.modal() functions and.show() functions don't seem to work. Here's the thing:

function gallery(_src) {
var fullPath = _src;
var fileName = fullPath.replace(/^.*[\\\/]/, '');
var newSrc = "./assets/img/" + fileName;
document.querySelector("div#galleryModal img").src = "./assets/img/" + fileName;

document.getElementById("galleryModal").show(); }

I'm blocked on this last javascript line. The objective: trigger #galleryModal.

Thanks for reading, thanks for helping !

We need to Create a modal instance if we want to operate with javascript check the below code and you find more info https://getbootstrap.com/docs/5.0/components/modal/#via-javascript

var galleryModal = new bootstrap.Modal(document.getElementById('galleryModal'), {
  keyboard: false
});


galleryModal.show();
