Question

我想在JavaScript内插入一个链接。

我想要此链接infoWindow.setContent('<a href="add-sesizare.php?lat=">Adaugă sesizare pentru locația ta actuală </a>.'); 将用户发送到add-sesizare.php?lat=&lng=&userid=

<?php include 'header.php'; 
session_start();


 if (isset($_SESSION['user'])) {
    $email = $_SESSION['user'];
    $query = "SELECT * FROM useri WHERE email='$email' LIMIT 1";
    $result = mysqli_query($con,$query);
    $user = mysqli_fetch_assoc($result);
    $userid = $user['id'];
} else { header('Location: login.php'); }
?>

您的'与"存在问题，并且您没有尝试添加地理位置服务返回的经纬度本地值（我认为这是必需的））。

infoWindow.setContent('<a href="add-sesizare.php?lat=' + pos.lat + '&long=' + pos.lng + '&userid=' + user_id +'">Adaugă sesizare pentru locația ta actuală </a>.');

（使用'表示JavaScript字符串，使用"引用HTML）。

代码段：

// Note: This example requires that you consent to location sharing when
// prompted by your browser. If you see the error "The Geolocation service
// failed.", it means you probably did not give permission for the browser to
// locate you.
var map, infoWindow;
var user_id = "$userid";

function initMap() {
  map = new google.maps.Map(document.getElementById('map'), {
    center: {
      lat: 46.35,
      lng: 21.3
    },
    zoom: 15
  });
  infoWindow = new google.maps.InfoWindow;

  // Try HTML5 geolocation.
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(function(position) {
      var pos = {
        lat: position.coords.latitude,
        lng: position.coords.longitude
      };
      infoWindow.setPosition(pos);
      infoWindow.setContent('<a href="add-sesizare.php?lat=' + pos.lat + '&long=' + pos.lng + '&userid=' + user_id + '">Adaugă sesizare pentru locația ta actuală </a>.');
      infoWindow.open(map);
      map.setCenter(pos);
    }, function() {
      handleLocationError(true, infoWindow, map.getCenter());
    });
  } else {
    // Browser doesn't support Geolocation
    handleLocationError(false, infoWindow, map.getCenter());
  }

  google.maps.event.addListener(map, 'click', function(event) {
    window.location = 'add-sesizare.php?lat=' + event.latLng.lat() + '&long=' + event.latLng.lng() + '&userid=' + user_id;
  });
}

function handleLocationError(browserHasGeolocation, infoWindow, pos) {
  infoWindow.setPosition(pos);
  infoWindow.setContent(browserHasGeolocation ?
    'Error: The Geolocation service failed.' :
    'Error: Your browser doesn\'t support geolocation.');
  infoWindow.open(map);
}

/* 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. */

html,
body {
  height: 100%;
  margin: 0;
  padding: 0;
}

<div id="map"></div>
