JavaScript - Google Maps Api V3 - Sidebar Problem
Hello, I had this working in v2, but I'm migrating to v3 and I'm having some trouble with my sidebar. I think it might be variable scope problem, but I can't find the answer.
I have a form which appends entries to an xml file, and my map script imports the xml to create markers and infowindows (all working). Functions to close the infowindow and recenter the map all work as well. It should also display a clickable sidebar with the names of the markers as links. It displays a side bar, but I only get one line which says 'undefined'. Here is my code: Code: var infowindow = new google.maps.InfoWindow(); var map = new google.maps.Map(); var side_bar_html = ""; var gmarkers = []; var shortname; var marker; function initialize() { var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","rp4.xml",false); xmlhttp.send(); xmlDoc = xmlhttp.responseXML; var markers = xmlDoc.getElementsByTagName("marker"); var point = new google.maps.LatLng(40.8068620, -96.6816790); var myOptions = { /* center: new google.maps.LatLng(40.8068620, -96.6816790), */ center: point, zoom: 4, mapTypeId: google.maps.MapTypeId.ROADMAP, /* mapTypeControl: True, mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU} */ }; // create the map map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); function bindInfoWindow(marker, map, infowindow, nfo) { google.maps.event.addListener(marker, 'click', function() { infowindow.close(); infowindow.setContent(nfo); infowindow.open(map, marker); map.panTo(marker.getPosition()); // map.setCenter(new google.maps.LatLng(lat,lng); map.setCenter(marker.getPosition()); }); } // document.getElementById("side_bar").innerHTML = side_bar_html; for (var i = 0;i<markers.length;i++) { var lat = parseFloat(markers[i].getAttribute("lat")); var lng = parseFloat(markers[i].getAttribute("lng")); point = new google.maps.LatLng(lat,lng); shortname = markers[i].getAttribute("company"); var company = markers[i].getElementsByTagName("company")[0].firstChild.nodeValue; var contact = markers[i].getElementsByTagName("contact")[0].firstChild.nodeValue; var str = markers[i].getElementsByTagName("str")[0].firstChild.nodeValue; var city = markers[i].getElementsByTagName("city")[0].firstChild.nodeValue; var phone = markers[i].getElementsByTagName("phone")[0].firstChild.nodeValue; var email = markers[i].getElementsByTagName("email")[0].firstChild.nodeValue; var web = markers[i].getElementsByTagName("web")[0].firstChild.nodeValue; var nfo = "<h1>"+company+"</h1>"+ "<p><b>"+company+"</b><br />"+ contact+"<br />"+ str+"<br />"+ city+"<br />"+ phone+"<br />"+ "<a href='mailto:"+email+"'>"+email+"</a></p>"+ "<a href='http://"+web+"'>"+web+"</a>"; marker = new google.maps.Marker({ position: point, map: map, title: company, clickable: true, }); marker.setMap(map); bindInfoWindow(marker, map, infowindow, nfo); } document.getElementById("side_bar").innerHTML = side_bar_html; } function myclick(k) { google.maps.event.trigger(gmarkers[k], "click"); // save the info we need to use later for the side_bar gmarkers.push(marker); // add a line to the side_bar html side_bar_html += '<a href="javascript:myclick(' + (gmarkers.length-1) + ')">' + shortname + '<\/a><br>'; return marker; } Similar TutorialsHi, Not sure where to post this. I currently have a web app which utilises Google Maps & Directions, however some of these maps and directions will be used in pdf creation with tcpdf. The problem arises with the fact that tcpdf doesn't read javascript and therefore cant show the map. Any ideas on what I can do to compensate? I am not familiar with the Google Maps API, but reading through several tutorials and their documentation I have been able to create a basic version of what I need. It is simply a list of places to the right of the map, which can be clicked and will center the map on that location. However, I seem to be unable to use geocoding so that I can use addresses instead of latitude and longitudes. Here's what I have so far: http://www.mpapo.org/testzone/gmaps.html That is the functionality that I need, but I need to be able to use addresses instead of coordinates. I found this script from a tutorial: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"/> <title>Google Maps JavaScript API Example</title> <script src="http://maps.google.com/maps?file=api&v=2&key=ADD_YOUR_KEY_HERE" type="text/javascript"></script> <script type="text/javascript"> //<![CDATA[ var geocoder; var map; var restaurant = "The Old Mohawk Restaurant"; var address = "821 Mohawk Street, Columbus OH"; // On page load, call this function function load() { // Create new map object map = new GMap2(document.getElementById("map")); // Create new geocoding object geocoder = new GClientGeocoder(); // Retrieve location information, pass it to addToMap() geocoder.getLocations(address, addToMap); } // This function adds the point to the map function addToMap(response) { // Retrieve the object place = response.Placemark[0]; // Retrieve the latitude and longitude point = new GLatLng(place.Point.coordinates[1], place.Point.coordinates[0]); // Center the map on this point map.setCenter(point, 13); // Create a marker marker = new GMarker(point); // Add the marker to map map.addOverlay(marker); // Add address information to marker marker.openInfoWindowHtml(place.address); } //]]> </script> </head> <body onload="load()" onunload="GUnload()"> <div id="map" style="width: 400px; height: 300px"></div> </body> </html> And it works, but how would I integrate it with the other script? I have tried several times/ways but it always crashes. Any ideas? Code: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var geocoder; var loc; geocoder = new google.maps.Geocoder(); var input = "32.83036,34.974339" var latlngStr = input.split(",",2); var lat = parseFloat(latlngStr[0]); var lng = parseFloat(latlngStr[1]); var latlng = new google.maps.LatLng(lat, lng); geocoder.geocode({'latLng': latlng}, function(results, status) { loc = results[1].formatted_address; }); </script> I need to use that var ("loc") in another place in my code, after the function finished running. Hi, I'm not sure where I have translated this incorrectly. I have one google map embedded on my page which works fine. But I wanted to add a second one. I thought the easiest way to do this would be to have a second page which is called later on with all the details on it for the second map. However although I think (this I presume is where I went wrong) I have replicated the instructions correctly the place holder for the second map just remains blank. This is the code for my called page with the instructions for the second map: PHP Code: <?php echo $_POST['Map'] . '<br />'; ?> <div id="placemap_canvas"></div> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> html {height:250px} body {height:250px} #placemap_canvas {width:100%; height:150px;} </style> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true" /> </script> <script type="text/javascript"> var latlng = new google.maps.LatLng ( <?php include("dbconnect.php"); $result = mysql_query("SELECT * FROM regions WHERE RegionPId='{$_POST['Map']}'"); while($row = mysql_fetch_array($result)){ echo $row['maplink']; } mysql_close($con); ?> ); var myOptions = { zoom: 4, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("placemap_canvas"), myOptions); } </script> And this is the script of the main page, just in case I would be better off keeping them both in one place. Code: <head> <script type="text/javascript"> function loadSubPlace(File,ID,Msg,Eile,EID,Esg){ loadXMLDoc1(File,ID,Msg); var mimer = setTimeout(function(){loadXMLDoc1(Eile,EID,Esg)},5000); } </script> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> html {height:250px} body {height:250px} #map_canvas {width:30%; height:250px;} </style> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true" /> </script> <script type="text/javascript"> function initialize() { var latlng = new google.maps.LatLng ( <?php include("dbconnect.php"); $result = mysql_query("SELECT * FROM countries WHERE Country='{$_SESSION['Country']}'"); while($row = mysql_fetch_array($result)){ echo $row['Map']; } mysql_close($con); ?>); var myOptions = { zoom: 4, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); } </script> </head> <body onload="initialize()"> <div class="countryright" id="map_canvas"> include("dbconnect.php"); $snowball=explode(';',$_POST['syringa']); $turnsol=$snowball[1]; $violet =$snowball[2]; $wakerobin=$snowball[3]; global $turnsol; global $violet; global $wakerobin; echo '<center><b><big>' . $wakerobin.

'\'));" />'; echo '<br /><br /><div id="txtHintPlaceSub"></div><br /><br />'; mysql_close($con); ?> I've cut out the script that doesn't relate to this so I hope I haven't missed anything important. I have some problems with intergrating google maps into my page I cant seem to get a marker to appear on my map. I have tried numerous methods but non seem to work. I have integrated the google maps on my main site, repositioned and re-sized. The code below is a test page i work on to get code to work. It's just a map on a page entire code: <!DOCTYPE HTML> <html> <head> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> html { height: 100% } body { height: 100%; margin: 25px; padding: 25px } #map_canvas { height: 100% } </style> <script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?key=AIzaSyDrxZnpYBNIwzBFVYaDY__BMONEjNEGZaI&sensor=false"> </script> <script type="text/javascript"> function initialize() { var myLatlng = new google.maps.LatLng(-25.363882,131.044922); var myOptions = { zoom: 4, center: myLatlng, mapTypeId: google.maps.MapTypeId.ROADMAP } var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);} var marker = new google.maps.Marker({ position: myLatlng, map: map, title:"Hello World!" }); </script> </head> <body onload="initialize()"> <div id="map_canvas" style="width:100%; height:100%"></div> </body> </html> can anybody tell my where i am going wrong and just the map appears with no marker? thanks I am using jMapping(http://vigetlabs.github.com/jmapping/) for using jQuery with google maps. What I'm trying to do is add an event listener so that when you click on a marker it will call a function I made within the jMapping function. Does anyone have any clues? everything I've tried doesn't work.
Hi I have just started looking at the Google maps, and have atutorial that will get the co-ordinates. What I want this to do, is then populate two fields on a form one called longitude and one called latitude Code: function usePointFromPostcode(postcode, callbackFunction) { localSearch.setSearchCompleteCallback(null, function() { if (localSearch.results[0]) { var resultLat = localSearch.results[0].lat; var resultLng = localSearch.results[0].lng; var point = new GLatLng(resultLat,resultLng); callbackFunction(point); }else{ alert("Postcode not found!"); } }); localSearch.execute(postcode + ", UK"); } Any ideas/tips would be be much appreciated Hey all I'm quite a newbie at javascript and I'm trying to have links to google maps markers. I have a page with my embeded google maps on it and some markers. What I'm basically looking to do is have a web page with a menu down the side and when you click the menu items, the google maps markers would pop up on the map. For example, city attractions down a side menu and when you click say restaurants, the markers would pop up the location restaurants in a certain place, then you could click pubs and the restaurant markers would dissapear and the pub markers would appear. Can anyboy help me with this or even direct me to some code that would help. Thanks all. I'm completely at a loss how to embed a map with the new google maps api setup. I found a snippet of code that I dropped in with some small database variables pulled in and was done. Then an error came that the API was no good. So I went in and set up an anaccount, got an api and now I just simply have no clue what their instructions are saying I need to do. Gah! Here's what I originally had: I now have a Client ID, client secret and stuff. But no clue how to set up this url, etc. Code: </script> <script src="//maps.google.com/maps?file=api&v=2&key=AIzaSyD4iE2xVSpkLLOXoyqT-RuPwURN3ddScAI" type="text/javascript"></script> <script type="text/javascript"> function initialize() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById("map_canvas")); map.setCenter(new GLatLng(<?php echo $c_row['location_longitude']; ?>,<?php echo $c_row['location_latitude']; ?>), 13); // Add the latitude/longitude marker to the map var point = new GLatLng(<?php echo $c_row['location_longitude']; ?>,<?php echo $c_row['location_latitude']; ?>); map.addOverlay(new GMarker(point)); map.setUIToDefault(); } } </script> <b>Map:<br><br><div id="map_canvas" style="width: 500px; height: 300px; z-index:4000;border-width:medium;border-color:#030;"></div></b> Hey I'm quite new at javascript and am currently in the process of creating a site that embeds google maps using an xml document.

Each pin is setup to use our blue custom icon image. I'm trying to make it so that when you click on a pin, that particular pin changes to a green version of the icon, and all the reset stay blue.

I'm developing a small application with Google Maps API for use in Wordpress and didn't want to place all the javascript into the Worpress page template file. But whenever I place the javascript that works fine in page tempalte into separate javascript file in Wordpress, all of the code using Google Maps API except the code that runs Maps itself stops working. So the Maps runs but for example Geocoder does not. I'm simulatenously using Google's jQuery API. I hope someone has experience with this and can help me. Hi, Not sure how difficult this will be but im working on a javascript/HTML5 game, and thought it would be interesting to allow for people to add their score to a google map at their location. I can get the google map and allow people to add their own markers but i dont no how i would store them, and then reload them when someone plays the game. any ideas? Thanks, Luke I'm trying to make a map that will show your current location, but also load an xml file to show certain attractions in your area. I have the code to work for getting your current location, but I can't figure out how to implement loading the xml file and placing markers based off of that xml file. Here is the code for getting my location: Code: function show_position(p) { document.getElementById('current').innerHTML="latitude="+p.coords.latitude.toFixed(2)+" longitude="+p.coords.longitude.toFixed(2); var pos=new google.maps.LatLng(p.coords.latitude,p.coords.longitude); map.setCenter(pos); map.setZoom(14); var infowindow = new google.maps.InfoWindow({ content: "<strong>yes</strong>" }); var marker = new google.maps.Marker({ position: pos, map: map, title:"You are here" }); google.maps.event.addListener(marker, 'click', function() { infowindow.open(map,marker); }); } </script > Can anybody help me figure this out? Thank you in advance |
