1.1.2
A jQuery Latitude and Longitude plugin to pick a location using Google Maps.
Supports multiple maps. Works on touchscreen. Easy to customize markup and CSS.
Basic functions
Move the marker on the map to receive the updated latitude, longitude and zoom values in the hidden fields
"location_changed" event will be fired, with the gllLatlonPicker Node JS object as attribute for easy access
Map with location search field:
If the search has results, the first element will appear on the map (with the default zoom value 11)
You can set default latitude, longitude and zoom values in the hidden fields
Use any custom id you want
Map with reverse lookup:
WHen the position changes the location's name will be returned
The "location_changed" event will also be fired with the gllLatlonPicker Node JS object as attribute
To disable this, you can set queryLocationNameWhenLatLngChanges param to false
Adjust latitude, longitude and zoom fields on the fly:
Set any default latitude, longitude and zoom values. The map shows your data after pressing the update button.
Any fields can be hidden or visible fields to ease user input
To use the Maps JavaScript API and the Geocoding API, you must get an API key which you can then add to your website, or web server. The API key is used to track API requests associated with your project for usage and billing. https://developers.google.com/maps/documentation/javascript/get-api-key#get-an-api-key
Import jQuery and Google Maps (don't forget to change the Google Maps script import tag to include your API key):
<script src="https://github.com/wimagguc/jquery-latitude-longitude-picker-gmaps/raw/master/js/jquery-2.1.1.min.js"></script>
<script src="https://github.com/wimagguc/jquery-latitude-longitude-picker-gmaps/raw/master//maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&sensor=false"></script>Import the plugin:
<link rel="stylesheet" type="text/css" href="https://github.com/wimagguc/jquery-latitude-longitude-picker-gmaps/blob/master/css/jquery-gmaps-latlon-picker.css"/>
<script src="https://github.com/wimagguc/jquery-latitude-longitude-picker-gmaps/raw/master/js/jquery-gmaps-latlon-picker.js"></script>Add a HTML markup:
<fieldset class="gllpLatlonPicker">
<input type="text" class="gllpSearchField">
<input type="button" class="gllpSearchButton" value="search">
<div class="gllpMap">Google Maps</div>
<input type="hidden" class="gllpLatitude" value="20"/>
<input type="hidden" class="gllpLongitude" value="20"/>
<input type="hidden" class="gllpZoom" value="3"/>
</fieldset>(See more options in the demos)
If you want to modify the default parameters, you need to disable the auto-init procedure first. You can do this by adding the following code when importing the plugin scripts:
<link rel="stylesheet" type="text/css" href="https://github.com/wimagguc/jquery-latitude-longitude-picker-gmaps/blob/master/css/jquery-gmaps-latlon-picker.css"/>
<script>
$.gMapsLatLonPickerNoAutoInit = 1;
</script>
<script src="https://github.com/wimagguc/jquery-latitude-longitude-picker-gmaps/raw/master/js/jquery-gmaps-latlon-picker.js"></script>Then copy the init code from "jquery-gmaps-latlon-picker.js" and extend it. Here is an example:
<script>
$(document).ready(function() {
// Copy the init code from "jquery-gmaps-latlon-picker.js" and extend it here
$(".gllpLatlonPicker").each(function() {
$obj = $(document).gMapsLatLonPicker();
$obj.params.strings.markerText = "Drag this Marker (example edit)";
$obj.params.displayError = function(message) {
console.log("MAPS ERROR: " + message); // instead of alert()
};
$obj.init( $(this) );
});
});
