    Help needed for populating the html5 geolocation value in the text box in a form

    hi,
    I would be helpful if you can guide me with my code below is my code and I wish to populate my value of the text box with the value i get from my geolocation of the device which I obtain from the javascript below so that i can use for various purpose for searching or may be for filling the form with the current geolocation values.

    i am able to get the location when i press the button but i am unable to populate textboxes below with the values i get by using my browser.

    I would be thankful if anyone can help me with the correction of my codes

    This works in Firefox 30 and IE11 but Chrome 36.x won't let me "unblock" my own computer from location tracking.

    I think most of your problem was not using the correct element IDs in your JS. But I took that opportunity to update the HTML to the 21st century .

    FYI, I used this page as a resource:
    https://developer.mozilla.org/en-US/...ng_geolocation

    HTML Code:
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="UTF-8">
    <title>Lat-Lon</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min.css">
    <style>
    .display{
    	padding-top: 20px;
    	padding-bottom: 20px;
    }
    </style>
    <script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
    <script src="http://code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min.js"></script>
    <script src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>
    
    <script>
    function showlocation() {
    	navigator.geolocation.getCurrentPosition(function(position) {
    		callback(position.coords.latitude, position.coords.longitude);
    	});
    }
    
    function callback(lat,lon) {
    	document.getElementById('latitude').innerHTML = lat;
    	document.getElementById('longitude').innerHTML = lon;
    
    	document.getElementById('latitude1').value = lat;
    	document.getElementById('longitude1').value = lon;
    
    }
    </script>
    </head>
    <body>
    <div>
    	<input type="button" value="Show my location" onclick="javascript:showlocation()">
    </div>
    
    <div class="display">
    	Latitude: <span id="latitude"></span><br>
    	Longitude: <span id="longitude"></span>
    </div>
    
    <form>
    	<input type="text" id="latitude1" name="latitude1" value = "">
    	<input type="text" id="longitude1" name="longitude1" value = "">
    </form>
    </body>
    </html>
