How to change the radius of the circle around the marker in Google Map API
11,183
You'll have to do something like this:
google.maps.event.addDomListener(
document.getElementById('circle_radius'), 'change', function() {
circle.setRadius(document.getElementById('circle_radius').value)
});
with this function you'll set up a function as listener for the circle_radius combo value change event. The function will update the radius of your circle with the value of the combo.

I am trying to change the circle radius by changing the value of combo-menu. So I wrote the a function for onchange as below.
function changeRadius(){ var selectedRadius = (document.getElementById("circle_radius").value)*1000; var circle = new google.maps.Circle({ map: map, radius: selectedRadius // radius unit is meter. }); var marker2 = new google.maps.Marker({ map: map, position: new google.maps.LatLng(40,-90), draggable: true, title: 'Drag me!' }); circle1.bindTo('center', marker2, 'position'); }
But It doesn't work. Any idea?
