How can I change the color of the markers (using leaflet), by click a button that is located in the infowindow of said marker?

Question

The markers represented on my map come from my database. Each of those markers have a infowindow with two buttons, "Recusar" and "Aceitar", if the button "aceitar" is clicked I want to change the color of just the marker that I selected previously. If the button "recusar" is clicked I want that marker to be deleted of my map. The function called "aceite()" doesn't work.

<div id="map"></div>

 <script>
     var map = L.map('map').setView([39.694502, -8.130573], 7);
     L.tileLayer('https://api.maptiler.com/maps/topo/256/{z}/{x}/{y}.png?key=7YZ2VQZiOPItbtjSPYWe', {

}).addTo(map);

Can someone help me solve this problem?

Change your code to:

var clickedmarker = null;
function onClick(e) {
    var popup = e.target.getPopup();
    var content = popup.getContent();
    clickedmarker = e.target;

    console.log(content);
}


function aceite() {
    var greenIcon = L.icon({
        iconUrl: 'https://cdn3.iconfinder.com/data/icons/basicolor-signs-warnings/24/186_fire-512.png',
        iconSize: [35, 35], // size of the icon
        shadowSize: [50, 64], // size of the shadow
        iconAnchor: [22, 94], // point of the icon which will correspond to marker's location
        shadowAnchor: [4, 62],  // the same for the shadow
        popupAnchor: [-3, -76] // point from which the popup should open relative to the iconAnchor


    });

    if(clickedmarker){ //if the object exists and is not null / undefined
      clickedmarker.setIcon(greenIcon);
    }
    clickedmarker = null;
}

//For deleting the marker:
function recusado(){
    if(clickedmarker){ //if the object exists and is not null / undefined
      clickedmarker.removeFrom(map);
    }
    clickedmarker = null;
}
