Google Maps Javascript API: marker.setPosition Issue
google-maps, javascript, marker
Solution
setPosition is a method. You need to modify your code to
marker.setPosition(myLatlng);
Please check whether it works.
Problem
It's probably something obvious... but I cannot see it. The following code works as expected for everything except the marker.setPosition action: ``` <head> <title>Test Simulation</title> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> html { height: 100% } body { height: 100%; margin: 0; padding: 0 } #map_canvas { height: 100% } </style> <script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?key=x&sensor=false"> </script> <script type="text/javascript"> var marker = null; var myLatlng = null; var map = null; var image = null; var mapOptions = null function movemarker() { xmlhttp=new XMLHttpRequest(); xmlhttp.open("GET","http://x.com/x13/?testloc=1",false); xmlhttp.send(); var data = xmlhttp.responseText; vals = data.split(','); latv = parseFloat(vals[0]); lonv = parseFloat(vals[1]); myLatlng = new google.maps.LatLng(latv,lonv); var fld = document.getElementById('before_map'); fld.innerText = ' ' + 'lat:' + latv + ', lon: ' + lonv + ' ' + myLatlng.toString(); marker.setPosition = myLatlng; } function initialize() { myLatlng = new google.maps.LatLng(44.809122,-36.650391); mapOptions = { center: myLatlng, zoom: 3, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions); image = 'http://x.com/x_icon.gif'; marker = new google.maps.Marker( { position: myLatlng, map: map, icon: image, title:"Hello World!" }) window.setInterval("movemarker()",5000); } </script> </head> <body onload="initialize(); "> <div id="before_map">Test area...</div> <div id="map_canvas" style="align:right; width:600; height:500"></div> ``` The "before_map" test area shows the new latitude and longitude values -- which update every 5 seconds. I've made adjustments based on answers to similar questions but I'm still stuck.
