Extrapolate lat long from google map api in old static page code and put the variable in the Openstreetmap code

We have an old static site with google maps api in hundreds of pages. I'd like some help to extract the var cordinated here ( for example 38.11401,13.355926 (var fenway = new [login to view URL](38.11401,13.355926 )) and add the value to the open street map lat long value. Google code example function initialize() { var fenway = new [login to view URL](38.11401,13.355926); var mapOptions = { center: fenway, zoom: 15, mapTypeId: [login to view URL] }; var map = new [login to view URL]( [login to view URL]("map_canvas"), mapOptions); var panoramaOptions = { position: fenway, pov: { heading: 34, pitch: 10, zoom: 1 } }; var panorama = new [login to view URL]([login to view URL]("pano"),panoramaOptions); [login to view URL](panorama); initialize = function(){}; } var mymap = [login to view URL]('mapid').setView([here lat long from google var], 18); [login to view URL]('[login to view URL]{id}/{z}/{x}/{y}.png?access_token=[login to view URL]', { maxZoom: 18, attribution: 'Map data © <a href="[login to view URL]">OpenStreetMap</a> contributors, ' + '<a href="[login to view URL]">CC-BY-SA</a>, ' + 'Imagery © <a href="[login to view URL]">Mapbox</a>', id: '[login to view URL]' }).addTo(mymap); var marker = [login to view URL]([here lat long from google var], {draggable: true} ) .addTo(mymap); var popup = [login to view URL](); function onMapClick(e) { popup .setLatLng([login to view URL]) .setContent("You clicked the map at " + [login to view URL]()) .openOn(mymap); } [login to view URL]('click', onMapClick);
