HTML5 geolocation watchPosition getting called just once -


i creating android application using html 5 , want access latlong user user moves. have used watchpostion isgiving me user location once.

    var watchid; var geoloc;  function showlocation(position) {   var latitude = position.coords.latitude;   var longitude = position.coords.longitude;      var ll=new google.maps.latlng(latitude, longitude);     map.setcenter(ll);    console.log("latitude : " + latitude + " longitude: " + longitude); }  function errorhandler(err) {   if(err.code == 1) {     console.log("error: access denied!");   }else if( err.code == 2) {     console.log("error: position unavailable!");   }     }     if(navigator.geolocation){       // timeout @ 60000 milliseconds (60 seconds)       var options = {timeout:60000};       geoloc = navigator.geolocation;       watchid = geoloc.watchposition(showlocation,                                       errorhandler,                                      options);      }else{       console.log("sorry, browser not support geolocation!");    }

i've been working on similar few months ago. remember having same issue. maybe help.

$(document).ready(function(){       initlocationprocedure(); }  function initlocationprocedure() {     map = new google.maps.map(document.getelementbyid('map_canvas'), {           zoom : 17     });      if (navigator.geolocation) {         navigator.geolocation.getcurrentposition(displayandwatch, locerror, {             enablehighaccuracy : true,             timeout : 60000,             maximumage : 0         });     } else {         alert("your phone not support geolocation api");     } }  function displayandwatch(position) {     // set current position     setuserlocation(position);     // watch position     watchcurrentposition(); }  function setuserlocation(pos) {     // marker userlocation     userlocation = new google.maps.marker({            map : map,            position : new google.maps.latlng(pos.coords.latitude, pos.coords.longitude),            title : "you here",            icon : "../img/user-location.svg",     // scroll userlocation     map.panto(new google.maps.latlng(pos.coords.latitude, pos.coords.longitude)); });

here looking for

function watchcurrentposition() {     var positiontimer = navigator.geolocation.watchposition(function(position) {         setmarkerposition(userlocation, position);         map.panto(new google.maps.latlng(position.coords.latitude, position.coords.longitude));     }); }  function setmarkerposition(marker, position) {      marker.setposition(new google.maps.latlng(position.coords.latitude, position.coords.longitude));      console.log(position); }
