Activate getFeatureInfo on button cklick

[diskmanti]

Hello,

I am trying to use your plugin and activate the getFeatureInfo request on a button click, a separate button using easyButton. I red the docs but there was no mention on how to activate the request on a button press, only on map click event.

Thanks in advance

The standard WMS GetFeatureInfo request requires an (x,y) pixel value from a previously returned image from GetMap request.
For similar task I use workaround with positioning map to object with known coordinates and calling identify function with necessary arguments:

var point = L.latLng(...);
map.setView(point, map.getZoom(), { animate: false });
wmsOverlay.identify({                    
    containerPoint: map.latLngToContainerPoint(point),
    latlng: point
});

It's probably possible to do this without altering map state, but it will require some work with projecting/unprojecting coordinates.
