<!DOCTYPE html> <html> <head> <title>Geolocation</title> <meta name="viewport" content="initial-scale=1.0, user-scalable=no"> <meta charset="utf-8"> <style> /* Always set the map height explicitly to define the size of the div * element that contains the map. */ #map { height: 100%; } /* Optional: Makes the sample page fill the window. */ /* map包含在body中，使用百分比表达时，是根据父容器的大小决定的，所以body html必须写为100% */ html, body { height: 100%; margin: 0; padding: 0; } </style> </head> <body> <div id="map"></div> <script> // Note: This example requires that you consent to location sharing when // prompted by your browser.
