  var x = document.getElementById("x");
  function getLocation() {
    if (navigator.geolocation) {
      navigator.geolocation.getCurrentPosition(showPosition, showError);
    } else {
      x.innerHTML = "该浏览器不支持定位功能！";
    }
  }
  function showPosition(position) {
    x.innerHTML = "纬度：" + position.coords.latitude + "\n经度："
        + position.coords.longitude;
  }
  function showError(error) {
    switch (error.code) {
    case error.PERMISSION_DENIED:
      x.innerHTML = "用户拒绝对获取地理位置的请求。";
      break;
    case error.POSITION_UNAVAILABLE:
      x.innerHTML = "位置信息是不可用的。";
      break;
    case error.TIMEOUT:
      x.innerHTML = "请求用户地理位置超时。";
      break;
    case error.UNKNOWN_ERROR:
