The content of this article is about the method code of js to obtain GPS coordinates. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
No more nonsense, let’s go straight to the code
1. This is relatively simple
function getLocation(){ if(navigator.geolocation){ //判断是否有这个对象 navigator.geolocation.getCurrentPosition(function(pos){ console.log("经度:"+pos.coords.longitude+ "纬度:"+pos.coords.latitude) }) }else{ console.log("当前系统不支持GPS API") } }
2. It’s more comprehensive. In fact, it’s not necessary. It depends on the individual. Like it
function getLocation(){ var options={ enableHighAccuracy:true, maximumAge:1000 } if(navigator.geolocation){ //浏览器支持geolocation // alert("浏览器支持geolocation"); navigator.geolocation.getCurrentPosition(onSuccess,onError,options); }else{ //浏览器不支持geolocation alert("浏览器不支持geolocation"); } }
When the acquisition is successful
function onSuccess(pos){ console.log("经度:"+pos.coords.longitude+ "纬度:"+pos.coords.latitude) }
When the acquisition fails, this error is deliberately written in detail to let you understand why it failed
function onError(error){ switch(error.code){ case 1: alert("位置服务被拒绝"); break; case 2: alert("暂时获取不到位置信息"); break; case 3: alert("获取信息超时"); break; case 4: alert("未知错误"); break; } }
