javascript - Is there a way to tell Google map to zoom out centered on a marker and show a calculated bounding box? -


when visitor clicks site shows streetview @ location. when exit picture code fetches nearest 2 marker coordinates (from mongodb) , zooms map out include calculated bounding box.

i have map remain centered on marker visited , zoom out enough show complete bounding box. user keep track of they've been.

click image calculate bounding box

the marker image 1 on left. can see bounding box centered.

enter image description here

i've had read through nothing seemed obvious me. google api v3 have method this? 

/**** collect data restful service code gets nearest 2 markers , calculates zoom set map include them in view. ****/ bounds = new google.maps.latlngbounds(); bounds.extend(new google.maps.latlng( data.locs.lat, data.locs.lng )); nearest = {}; $.ajax({     type: "get",     datatype: "json",     data: { lat : data.locs.lat,  //the marker viewing              lng : data.locs.lng},     async: false,     url: "php/restful.get.nearest.markers.php",     success: function (data) {         nearest = data;       } }); $.each(nearest, function ()  {     bounds.extend(new google.maps.latlng( this.locs.lat, this.locs.lng )); }); /**** end collect data restful service ****/ map.fitbounds(bounds);   new google.maps.rectangle({     bounds: bounds,     map: map,     fillcolor: "#000000",     fillopacity: 0.2,     strokeweight: 0 });

this not easiest way can start.

look @ google maps api mapoptions. see property called zoom, third bottom, controls map zoom(obviously).

then there 2 methods getzoom , setzoom in map's methods can used programmatically control zoom level of map.

you have experiment these , of course setcenter should not big issue.

experiment , find zoom level covers, in terms of distance, calculate bounding box covers , set zoom level , center accordingly.
