navigator.geolocation.getCurrentPosition in cordova/android gives max 10 meter accuracy. I didn't use any plugin for geolocation. But some other apps shows 3 meter accuracy for the same place. navigator.geolocation.getCurrentPosition won't give better accuracy? Sadly the cordova-plugin-geolocation for Android doesn't provide any native code, just have the minimal code to handle the permissions for Android 6+. For getting the location it uses the WebView implementation of geolocation, so if using enableHighAccuracy: true you don't get the accuracy you expect, there is nothing you can do about

I'm trying to play with the scope of js to pull a variable out of navigator.geolocation.getCurrentPosition var lat; function callback (position) { lat = position.coords.latitude; } navigator.geolocation.getCurrentPosition(callback,fail,{timeout:10000}); // after getCurrentPosition succeeds alert(lat); // this alerts null The above code cannot store position.coords.latitude in the lat variable because of the scope. Is there a way to do this? You have to remember the async\ajax nature. this is the execution order of your code: var lat; alert(lat); // this alerts null navigator.geolocation

I'm building a small script that clients will install on their page. Geolocation is not necessary for it, however if it exists it would be nice to have. Is there a way for me to check if the clients page has requested geolocation information and if the user selected allow get the lat & lon without creating another prompt? It isn't possible with the geolocation API but it is possible with the new permission API This code is useful if you want to try to receive the coordinates but don't want to bother the user with a prompt dialog cuz the coordinates is not that important and may as well

Apart from setting a cookie the first time round, is there a way of detecting whether a user has already given permission for navigator.geolocation to return the lat/long of the browser? If there is, what is it and is it the same across all browsers or different across all browsers? This subject has been partially answered elsewhere According to GeoLocation API – Chrome / Safari – Permission management and Visual Differences , Chrome asks for a revokable one-time permission. I haven't finished reading the article, but it would seem that storage of permissions is not a purely-Chrome thing to do

I need JavaScript to display a manual entry if geolocation is declined. What I have tried: Modernizr.geolocation navigator.geolocation Neither describes if user has previously declined access to geolocation. Cristian Sanchez watchPosition and getCurrentPosition both accept a second callback which is invoked when there is an error. The error callback provides an argument for an error object. For permission denied, error.code would be error.PERMISSION_DENIED (numeric value 1 ). Read more here: https://developer.mozilla.org/en/Using_geolocation Example: navigator.geolocation.watchPosition
