You can now take advantage of HTML5 Geolocation API in order to get user’s location details such as latitude and longitude. What was our requirement? 1) Whenever user visits our website, we want to track user’s location (e.g. latitude and longitude). 2) Page should ask to access location only one time during that session, it should not ask every-time. Using geolocation API will ask user to whether user wants to share location or not? Implementation: Below code snippet shows how to use HTML Geolocation API and store user’s location details in cookie so that it should not ask to share location each time. Step-1: Define two hidden textboxes to store user’s latitude and longitude value.
Step-2: Write jQuery to access user’s latitude and longitude and store it in cookie for future use.
