JS equivalent for jQuery one()

Question

Can someone point me towards a solution for the following? I\'m trying to find a JS equivalent for this jQuery code:

var formSelector = \'my selector here\';         


        

Answer 1

Here's a really simple solution using data attributes.

document.querySelector('#click').addEventListener('click', function(e){
    if(e.currentTarget.dataset.triggered) return;
    e.currentTarget.dataset.triggered = true;
    alert('clicked');
})
