Google Map Api V3 Marker Focus

Similar Tutorials

View Content

Hey Guys,

I am currently building a web app that uses Google Maps V3 api.

You select a check box which then shows a marker on the map.

My issue is, when you select and the marker is placed, I need the map to focus to that point, it currently embeds but doesn't focus.

Is there a particular function I could use to achieve this?

My current code is shown below:

Code:

var locations = [
    // Longitude, Latitue, Content, Country Code, City Name
	[51.481383, -3.114967, holidayOverlay, 'UK', 'Cardiff'],
	[52.362393, 4.893379, holidayOverlay, 'NL', 'Amsterdam'],
	[48.852314, 2.350089, holidayOverlay, 'FR', 'Paris'],
	[40.18884, -3.716812, holidayOverlay, 'SP', 'Madrid'],
	[53.800651, -4.064941, holidayOverlay, 'IT', 'Rome'],
	[42.041134, 1.889648, holidayOverlay, 'SP', 'Costa Brava'],
	[36.79334, 27.234421, holidayOverlay, 'GR', 'Kos'],
	[37.014581, -7.933888, holidayOverlay, 'PT', 'Algarve'],
	[28.358776, -14.05426, holidayOverlay, 'PT', 'Fuerteventura'],
	[29.046854, -13.589973, holidayOverlay, 'SP', 'Lanzarote'],
];

// Only create marker when checked
for (i = 0; i < locations.length; i++) {
    if (locations[i][4] == location) {
        var marker = new google.maps.Marker({
            position: new google.maps.LatLng(locations[i][0], locations[i][1]),
            map: map,
            icon: plotImage
        });
        var title = locations[i][4];
        var content = locations[i][2];
    }
}

I have left a lot of the code out to save you a headache.

Thanks.

I am having a problem with google maps api. i have created a map which will place a marker on the location entered in a text field.

There are two other fields on the page called latbox and lngbox which i want to be populated when the marker is initially created and when it is dragged. so far im just working on the dragged and cant get it working although trying multiple ways.

Code:

    <script type="text/javascript">
  var geocoder;
  var map;
  var marker=false;
  function initialize() {
    geocoder = new google.maps.Geocoder();
    var latlng = new google.maps.LatLng(-34.397, 150.644);
    var myOptions = {
      zoom: 8,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
  }

      
    function codeAddress() {
    var address = document.getElementById("address").value;
    geocoder.geocode( { 'address': address}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
        map.setCenter(results[0].geometry.location);
        var marker = new google.maps.Marker({
            map: map,
            position: results[0].geometry.location,
            draggable: true
        });
      } else {
        alert("Geocode was not successful for the following reason: " + status);
      }
    });
  }
  
      google.maps.event.addListener(marker, 'drag', function(event){
       document.getElementById("latbox").value = event.latLng.lat();
       document.getElementById("lngbox").value = event.latLng.lng();
    });
    </script>
  </head>
  <body onload="initialize()">
    <div id="map_canvas" style="width:320px; height:320px"></div>
      <div>
    <input id="address" type="textbox" value="Sydney, NSW" />
    <input type="button" value="Locate" onclick="codeAddress()" />
  </div>
      <div id="latlong">
    <p>Latitude: <input size="20" type="text" id="latbox" name="lat" ></p>
    <p>Longitude: <input size="20" type="text" id="lngbox" name="lng" ></p>

Right I have google maps connected to a database which holds stockists and their information. The user enters their postcode and radius and markers are put on the map of stockists in the radius of their postcode. I have this all working fine and the database chucks the information into an xml file fine. The problem im having is displaying the information in the pop up window of the marker.

the only information displayed in the sidebar entry is the name and distance and on the marker just the name.

I've been looking for a solid solution for how to add numbers to markers. Most that I've seen involve an asp page with a post back of an image based on the query string.

I am trying to do something like what MarkerClusterer does. Here is an example:
http://google-maps-utility-library-v...e_example.html

I've looked over their code and cant seem to pull out the part where it adds the numbers to the marker, I'm still new to jquery.

Here is a link to the source code:

Would 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;

Google Maps Api Geocode And Update Marker Position

Hello,

I have the code below but for some reason it only works when adding the marker to the map (map click). When I drag the marker around, the coordinates and closest address don't update.

This code works if I add the marker straight in the initialize() function but not when I add it within the addListenerOnce for map click event.

I want to be able to add 1 marker to the map, and update its address and coordinates when dragging the marker around.

If someone can help me sort this out...

Google Maps - Marker/info Bubble Problems

I've been trying for some time now to create some code which dynamically adds markers to a google map. I've now managed this but I still have a slight problem I think with the javascript side of things.

I've included a snippet of the code which shows 2 markers on the map. They should be 2 different markers but they are the same, and the contents of the popup bubble should be each individual postcode, but they both show the same postcode. Does anyone have any ideas?

Thanks

Inserting Google Maps Coordinates Into Text Field After Marker Location Updated

Similar Tutorials

Hi guys,

Hopefully a really quick question. I'm a JS novice, and am looking for a way to output the coordinates of a Google maps marker into the value of two text fields, one for latitude and one for longitude.

The code below is a simple location search which returns a result with a draggable marker. Currently, the coordinates in both text fields update when the location search is performed, but not when the marker is dragged to a new location afterwards.

Does anyone know the code to simply update the coordinates each time the marker is dropped on a new location?

      map.clearOverlays();
      if (!response || response.Status.code != 200) {

Most Efficient Way To Auto-refresh A Chatbox?

Similar Tutorials

View Content

If you go to a Youtube video by Justin Bieber or Rebecca Black, comments are constantly being posted and it seems like the autorefresh for the comments kicks in every half second. I don't plan on having millions of users viewing my page, but still, wouldn't having every user make a [mysql] request to the server every half second really take a toll on the server (especially since I don't plan to ever have the resources that Youtube has)? Facebook also seems to have instantaneous auto-refreshes, be it in comment boxes or their chat interface.

So what would be the best method to implement a near-instantaneous autorefresh system with minimal resource usage?

How To Auto Refresh The Page Only One Time?

Similar Tutorials

View Content

I've a web page when a user logs in, it will have a link that shows the "username" and a link for "logout".

After the user logs out, the "username" and the "logout" links will change to "login" and "register" links, respectively.

The page uses javascript to check a user cookie, if the user cookie exists, it will show the "username" link and the link for "logout". If no user cookie exists, "login" and "register" links will replace the "username" and "logout" links.

Here's the problem: When a user who has log in, clicks the "logout" link, a perl script will delete the user cookie, and redirects back to the same page. The page does not show "login" and "register" links AUTOMATICALLY. Both links will appear ONLY after the user MANUALLY Refreshes the page.

It appears that I need a system to refresh the page automacally ONLY one time. How can this be done?

Auto Refresh On Jquery Script

I currently have this on my companies website and it's having a bit of trouble sometimes where it will only work after a refresh. Is it possible to do a refresh of this div and script as soon as the site loads, instead of using the auto refresh. I tried using auto refresh and it works but whatever time interval I put for the auto refresh is the time that the script pops up, so it kind of just makes it worst.

Code:

					showHeading: false,
					headingText: "Latest Tweets",
					showProfileLink: false,
					showTimestamp: false
				});
			});
