Quick Reference
The navigator.geolocation property returns a geolocation object that can be used to locate the user’s position.
<!-- html element to place output -->
<p id="my_output"></p>// get location
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(my_position);
}
else {
document.getElementById('my_output').innerHTML = 'Geolocation is not supported by this browser.';
}
function my_position(position) {
document.getElementById('my_output').innerHTML = 'Latitude: ' + position.coords.latitude + '<br>' + 'Longitude: ' + position.coords.longitude;
}Note
The geolocation property is only available in secure contexts like HTTPS, and only after the user approves it.
Output
Latitude: 29.75589716474406
Longitude: -141.85376793156011Syntax
navigator.geolocationJavaScript Notes:
- When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- JavaScript is a case-sensitive language; firstName is NOT the same as firstname
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
- JavaScript variables must begin with a letter, $, or _
- JavaScript variables are case sensitive (x is not the same as X)
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
