Closing automatic popup on button click in OpenLayers?

Question

I'm using the fixed popup, to show the location, according to the latitude and longitude entered by the user. When you click the button to delete the search, would you like to run or close the automatic popup? How should I do? I'm using OpenLayers

var view = map.getView();

popup_lat_long.setPixelPosition([10,10], 'auto')
map.addOverlay(popup_lat_long)

document.getElementById('butonSearchLatLong').addEventListener('click', function() {
       
    view = map.getView();
    zoom = view.getZoom();
    
    var lat = parseFloat(document.getElementById('lat').value);
    var lon = parseFloat(document.getElementById('lon').value);

    // Converting lat long to mercator projection
    proj_lat_long = ol.proj.fromLonLat([lat, lon])

    // Zoom to lat lon
    map.setView(
        new ol.View({
            center: proj_lat_long,
            zoom: 17
        })

    popup_lat_long.setPixelPosition([10,10], 'auto')
    popup_lat_long.show(proj_lat_long, 'Lat: ' + lat + '<br/> Lon: ' + lon); 
});

document.getElementById('buttonDeleteLatLong').addEventListener('click', function() {
    view.setZoom(zoom);
    map.setView(view)
        
});

If you look at the docs of the ol-ext fixed popup, you'll see it has .hide() method, by which displayed popup can be hidden.

So relevant part of your code could look like this:

document.getElementById('buttonDeleteLatLong').addEventListener('click', function() {
  view.setZoom(zoom);
  map.setView(view);
  popup_lat_long.hide();
});
