@Faq

You need to initialise the modal like:

MicroModal.init({
  onShow: modal => console.info(`${modal.id} is shown`), // [1]
  onClose: modal => console.info(`${modal.id} is hidden`), // [2]
  openTrigger: 'data-custom-open', // [3]
  closeTrigger: 'data-custom-close', // [4]
  openClass: 'is-open', // [5]
  disableScroll: true, // [6]
  disableFocus: false, // [7]
  awaitOpenAnimation: false, // [8]
  awaitCloseAnimation: false, // [9]
  debugMode: true // [10]
});

So you use the onShow event listener to add your logic into or add a function reference.

https://micromodal.vercel.app/

I always set:

awaitCloseAnimation: true

So for example:

MicroModal.init({
  onShow: function(modal, activeElement, event){
     microModalShow(modal, activeElement, event);
   }
 …
});

function microModalShow(modal, activeElement, event) {
   if(modal.id === ‘someModalId’){
     console.log('event target data bundle id: ', event.target.getAttribute("data-bundle-id")); 
     // 1
   }
}

thank you @charlesr1971 , but still getting:
Uncaught TypeError: Cannot read properties of undefined (reading 'target')
It might be because of using different jquery version?

jQuery.fn.jquery
'3.4.1'

Your example using:
'3.6.3'

@Faq Hmmm. That’s a bit strange. Not sure that JQuery is being used, when I reference:

event.target

Although, maybe your version of JQuery is clashing with something in the micromodal library. I reckon this is highly unlikely?

All I can say, is that my codePen works, so maybe you have an old version of micromodal?

Try copying my code and then adapting it, for your own purposes. Once you have done this, if it still throws an error, post your code and I will try and debug it.

This kind of code, just won’t work:

$('#edit_data_modal').on('show.bs.modal', function (event) {
    var button = $(event.relatedTarget); // Button that triggered the modal
    var bundle_id = button.data('bundle_id'); // Extract info from data-* attributes
    var modal = $(this);
    modal.find('#bundle_id').val(bundle_id);
});

Yeah that was the case, had 0.4.2, solved with yarn upgrade micromodal@^0.4.10, again thank you :)

@Faq Awesome 👏🏻

Has any one integrated a way to have next and previous buttons for every modal thats on the page?

@jason-enstedt Yes. You could do something like:

JS:

var ordinal = 0;
		
function microModalShow(dir){
  var dir = (arguments[0] != null) ? arguments[0] : 'next';
	
	const modal = document.querySelectorAll(".modal");
	const max = modal.length;
	
	console.log('microModalShow modal: ',modal);
	
	console.log('microModalShow max: ',max);
	
	if (dir === 'next') {
		ordinal++;
	}
	else {
		ordinal--;
	}
	if (ordinal <= 0) {
		ordinal = 1;
	}
	if (max > 0) {
		if (ordinal > max) {
			ordinal = 1;
		}
	}
	MicroModal.show('modal-' + ordinal);
}

<a href="javascript:void(0);" class="mdl-button" onclick="microModalShow('previous');">Previous</a>
<a href="javascript:void(0);" class="mdl-button" onclick="microModalShow('next');">Next</a>
