JavaScript - Go To Google Maps Location On Page Load
Hi:
I'm new to this forum and JS. I simply want to be able to use the Google Maps API v3 to allow a location value entered in my app (by the user) to show that location via Google maps. The code below accomplishes this via an onClick event. How to accomplish the same WITHOUT an onClick? To be clear, it appears I need to be able to perform the geocode lookup to get the long/lat coordinates and then apply them. That all needs to occur on page load. Any tips on how to re-arrange this code to accomplish the desire goal are appreciated. Thanks much. Bill Code: <html>

Similar TutorialsI'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 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? Code: <html>

Many thanks in advance, I appreciate anyone who wants to help out! 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. Hi everyone, I'm putting together a family tree type organization chart and looking to be able to drag it around to view different parts similar to google maps. I believe javascript is the way to handle this but need some help pointing me in the right direction. Any help would be greatly appreciated. Thanks, Mike Hi all , I need some help in altering the location tag and the View Larger Map links to open in a new window, currently it opens in the same window.

I have a page with a GoogleMap with a GoogleBar and I would like the GoogleBar to appear with something written in it already and to have that search executed. In other words, I would like to "write something to the GoogleBar and press Enter" automatically as soon as the map loads. How can I do this? btw: By GoogleBar, I mean the search bar that appears on the map after using the enableGoogleBar() function. 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>

If anybody help with this and tell me where I am going wrong, it would be much appreciated. 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. Hi guys, I am a new poster and new to google maps. I have been working on geocoding and I have a problem, the example below works fine, all rollovers and icons work perfectly. However, the info window will only display for one point. I am assuming I have this line of code in the wrong place. new google.maps.event.addListener(marker, 'click', function() {infowindow.open(map,marker);}); Can anyone please help me?

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! Hello! 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. hello all, what i would like to implement is the following : http://mon.grnet.gr/network/maps/lite/?load&ip but, the problem is that, although the numerical data that show the traffic volume passing through a link are available to me, i do not have clue on how i can display them onto the map ... ? i would be thankful, if you could give me a piece of advice. Hello, I am working on creating a map using the google maps API. I would like to update the markers and info windows using an XML database. I know how to parse the XML using PHP if I was just going to create a table on the page, but for the life of me I can't find a complete and simple description of how to do it with javascript. I've been reading tutorials and W3 schools reference for over a week trying to figure it out. I'm new to javascipt, so some of the stuff I don't really understand. I did find a similar question posted on this forum, although I can't get it working. Here is my code (note: this code doesn't work, I know that I'm missing some way to load the xml and parse it, but I don't see how its done): Code: <!!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

The XML is set up like this: Code: <?xml version="1.0" encoding="UTF-8"?> <rp> <partner company="nameofcompany1" short="name1" street="123 fake street" city="New York" state="New York" zip="12345" lat="52.45545612" lng="-0.52664" /> <partner company="nameofcompany2" short=name2" street="231 notreal street" city="Chicago" state="IL" zip="23456" lat="55.45646" lng="-0.895423" /> </rp> I'm not really concerned with geocoding using the code, the number of entries shouldn't be more than a couple dozen, and I won't be adding a bunch at a single time. I was able to get the map working how I would like it, with multiple infowindows and markers, but I was having to put each into the code manually, with unique variables for each marker and info window. It seems like there is a much cleaner way to do this. If anyone can help me, it would be much appreciated. Hello i have a problem i need to resolve here is the script Code: script src="http://maps.google.com/maps?file=api&v=2.x&key=ABQIAAAAzr2EBOXUKnm_jVnk0OJI7xSosDVG8KKPE1-m51RBrvYughuyMxQ-i1QfUnH94QxWIa6N4U6MouMmBA" type="text/javascript"></script>

</p>

</form>
</body>
its all working well but i need to use it differently. Is there a way to make the form submit automatically , i already have the address and i will <php> it from my database. i want that the map will show in the page as soon as the user clicked on an ad(real estate ad). Basically what we need here is: To know how to call the functions and give the address from the database. <body onload="initialize()" onunload="GUnload()"> <form action="#" onsubmit="showAddress(this.address.value); return false"> <p> <input type="text" size="60" name="address" value="1600 Amphitheatre Pky, Mountain View, CA" /> <input type="submit" value="Go!" /> </p> <div id="map_canvas" style="width: 500px; height: 300px"></div> </form> </body> Is there a way just to use this command without the form onsubmit="showAddress(this.address.value); return false">? And give the address as a variable ? and when the page is uploading it will have already passed the address and the map will show Danny |
