地理位置API无法与Vue.js一起使用

Question

I am trying to grab geolocation for my app. Geolocation should be grabbed on created hook.

if (navigator.geolocation) {
  navigator.geolocation.getCurrentPosition(displayLocationInfo);
}

function displayLocationInfo(position) {
  const lng = position.coords.longitude;
  const lat = position.coords.latitude;

  console.log(`longitude: ${ lng } | latitude: ${ lat }`);
}

But my console is empty.

The real way to use Geolocation API is to check the availability of it on your device/browser before using it, so just add an else block to your existing code. Hope it'll help :) See more at MDN

 if ("geolocation" in navigator) { /* geolocation is available */ navigator.geolocation.getCurrentPosition(displayLocationInfo); function displayLocationInfo(position) { const lng = position.coords.longitude; const lat = position.coords.latitude; console.log(`longitude: ${ lng } | latitude: ${ lat }`); } } else { /* geolocation IS NOT available */ console.log('geolocation IS NOT available on your browser'); }
