JavaScript - Simple Problem Using Infowindows In Google Maps Api3
Similar TutorialsWould someone as be so kind to check my google maps script. For some reason the map is centering yet no marker (and info window) is being displayed. I'm (foolishly) using php to echo out the lat and long and the info window content yet everything seems to output okay...... Did a quick java de-bug and found the following error; Quote: Error: myLatlng is not defined Source File: xxx Line: 45 However the lat and lng are echo' out okay and the map is centered on the co-ordinates???? Much thanks!!!! Code: <script type="text/javascript">
function initialize() {
var myOptions = {
center: new google.maps.LatLng(53.989723,-7.361760),
zoom: 13,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
var contentString = '<div>'+
'<h3 id="fs">Alcohol Early Intervention Project (Cavan/Monaghan)</h1>'+
'<div>'+
'<p>Click here for a streetview map</p>'+
'</div>'+
'</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Alcohol Early Intervention Project (Cavan/Monaghan)"
});
var marker = new google.maps.Marker({
position: map.getCenter(),
map: map,
title: 'Click to zoom'
});
google.maps.event.addListener(marker, 'click', function() {
if (map.getZoom() == 13) {
map.setZoom(4);
} else {
map.setZoom(8);
}
});

I need to use that var ("loc") in another place in my code, after the function finished running. 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;

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;
}
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"

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? Hi, 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? 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>

I've cut out the script that doesn't relate to this so I hope I haven't missed anything important. 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 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.
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>

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. What I'm trying to do is categories the markers on my map. I am trying to make it so there are check boxes at the bottom and when i check the boxes, i.e. theatres, the markers will appear for the theatres and disappear when unchecked. Using some example code i have modified, i have so far got the maps to pickup the markers from the xml with the check boxes but the markers are all just on the page and the check boxes dont do anything and I am stuck as to of why. here's my code: Code: <!DOCTYPE HTML>

If anybody help with this and tell me where I am going wrong, it would be much appreciated. thanks 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 Hello, I'm just beginning to work with javascript and having a heck of a time with the syntax. I've worked with PC's for over 25 years, but my programming skills are weak and rusty. I have a jpg image(s) that I'm trying to get to "overlay" a Google base map and I know I'm so close, but can't figure it out. I've looked at plenty of sample code on Google's code pages, as well as others but I'm missing something. I can send the code if someone could please help. Thanks in advance! I need help making this script output a route on the map on top of the dollar amount it outputs right now. Here is a link to what im working on http://stallionshockey.org/testweb/ Any help would be greatly appreciated Thanks, Josh My google maps is showing a grey box and no map?!

Just need to properly add that to the end. I am okay at editing and adapting codes, but I don't know the sytax. Tried JSLINT but still confused. Probably quite simple. Thanks 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 Hey all, I was wondering if someone would be able to help me with a problem I've been having. I'm attempting to find coordinates for several addresses at a time. I'm using a for-loop to loop through an array of addresses. I figured it would be best to have a separate function to evaluate the coordinate given an address, and just call it in every loop. Note that my code below is simplified (I removed the for loop because that's not where I'm having trouble). I know that the issue is probably because I'm trying to return a value from an anonymous function... I tried making the variable global, I tried having a return line from within the anonymous function, nothing has worked... any tips? Thanks -- Code follows Code: function initialize(){
var geocoder = new google.maps.Geocoder(); // creating a new geocode object
var locCood = findcood('44106', geocoder);
}
function findcood(addr, geocoder)
{
var cood;
if (geocoder) {
geocoder.geocode({'address': addr}, function(results, status, cood){
if (status == google.maps.GeocoderStatus.OK)
cood = results[0].geometry.location;
else {
cood = null;
alert("Geocode was not successful for the following reason: " + status);
}
});
}
else
{
alert("No Geocode");
cood = null;
}
alert(cood);
return cood;
}
