Is there any way to v3 google.maps.Polygon disappear?

Question

Is there any way to v3 google.maps.Polygon disappear?

Instead of just hiding / removing the standard Google Maps V3 polygon, I want to disappear.

Is it possible? Are there any plugins there?

Answer 1

The following is the solution that I created to solve the uniform extinction of stroke and filling, and I made it easily reusable, making it a function.

seconds is the time that fading and callback will occur so that you can perform another action after it completes.

In my project, my callback function removes the polygon from the map and removes the variable.

function polygon_fadeout(polygon, seconds, callback){
    var
    fill = (polygon.fillOpacity*50)/(seconds*999),
    stroke = (polygon.strokeOpacity*50)/(seconds*999),
    fadeout = setInterval(function(){
        if(polygon.strokeOpacity + polygon.fillOpacity <= 0.0){
            clearInterval(fadeout);
            polygon.setVisible(false);
            if(typeof(callback) == 'function')
                callback();
            return;
        }
        polygon.setOptions({
            'fillOpacity': Math.max(0, polygon.fillOpacity-fill),
            'strokeOpacity': Math.max(0, polygon.strokeOpacity-stroke)
        });
    }, 50);
}

Javascript setInterval()/clearInterval() . - :

var opacity = [1, 0.8]
var polygon = new google.maps.Polygon({
        strokeColor: "#000099",
        strokeOpacity: opacity[0],
        strokeWeight: 2,
        fillColor: "#0000FF",
        fillOpacity: opacity[1],
        paths: [ /* your points here */ ]
});

var interval = setInterval(function() {
  if (opacity[0] <= 0.0 && opacity[1] <= 0.0) {
    clearInterval(interval);
    polygon.setVisible(false);
  } else {
    opacity[0] = Math.max(0.0, opacity[0] - 0.1);
    opacity[1] = Math.max(0.0, opacity[1] - 0.1);
    polygon.setOptions({strokeOpacity: opacity[0], fillOpacity: opacity[1]});    
  }
}, 50);
