我有一个Cordova/Phonegap应用程序,可以将地理位置(经度/纬度)推送到本地存储。我有一个问题,让这些变量推到mySQL数据库。我只是想在连接到mySQL时发送数据。我的代码看起来像:
index.html(地理位置设置)

    //find location info//
    function geolocation(){
        var options = enableHighAccuracy = true;
      watchID = navigator.geolocation.watchPosition(onSuccess, onError, options);

    //this functions runs if geolocation is returned//
        function onSuccess(position) {
            var lat = position.coords.latitude;
            var lng = position.coords.longitude;
            //save to local storage
            localStorage.setItem("latitude", lat);
            localStorage.setItem("longitude", lng);
            //tell user their lng and lat
            //alert("lat: " + lat + "long: " + lng);
        }
        //if cant get location give error//
        function onError(error) {
            alert("message: " + error.message);
            localStorage.setItem("message", error.message);
         }
        }
    geolocation();

在将数据发送到本地存储时工作正常。现在我需要做的就是onNetworkAvailable,将数据推送到mySQL。
My ondevice.js(在我的头脑中引用)
    // Wait for PhoneGap to load
//
function onDeviceReady() {
    if (parseFloat(window.device.version) === 7.0) {
          document.body.style.marginTop = "20px";
    }
      }

    document.addEventListener("deviceready", onDeviceReady, false);

    // PhoneGap is loaded and it is now safe to make calls PhoneGap methods

var isNetworkAvailable=true;

function onDeviceReady() {
    checkConnection();
    document.addEventListener("offline", setOffline, false);
    document.addEventListener("online", setOnline, false);
     }

     function checkConnection() {
         var networkState = navigator.network.connection.type;

     var states = {};
     states[Connection.UNKNOWN]  = 'Unknown connection';
     states[Connection.ETHERNET] = 'Ethernet connection';
     states[Connection.WIFI]     = 'WiFi connection';
     states[Connection.CELL_2G]  = 'Cell 2G connection';
     states[Connection.CELL_3G]  = 'Cell 3G connection';
     states[Connection.CELL_4G]  = 'Cell 4G connection';
     states[Connection.NONE]     = 'No network connection';

     alert('Connection type: ' + states[networkState]);
     }

 function networkAvailable() {
      return isNetworkAvailable;

     //var userID = $(this).attr('id');
    var getlat = window.localStorage.getItem("latitude", lat);
    var getlng = window.localStorage.getItem("longitude", lng);
     //alert($(this).attr('id'));
            $.ajax({
                type: "POST",
                url: 'myurl/dbUserLocation.php',
                data: { getlat : getlat, getlng : getlng},
                success: function(data)
                {
                    alert("Data sent!");
                },
        complete:function remove(){
        localStorage.removeItem("latitude");
        localStorage.removeItem("longitude");
        },
        error: function(){
        alert('Code 303A');
        }
                });
            }

    function setOffline() {
             isNetworkAvailable=false;
    }

    function setOnline() {
            isNetworkAvailable=true;
    }

以及要发送到mySQL的dbUserLocation.php:
      ini_set('display_errors',1);
      error_reporting(E_ALL);

      header('Access-Control-Allow-Origin: *');

      $hostdb = 'myhostip';
      $namedb = 'mydbname';
      $userdb = 'root';
      $passdb = 'mydbpass';

      $conn = new PDO("mysql:host=dbip; dbname=$namedb", $userdb, $passdb);
      $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);

      if(isset($_POST['longitude']) && ($_POST['latitude'])) {

      $longitude = $_POST['longitude'];
      $latitude = $_POST['latitude'];

      $stmt = "INSERT INTO row_location (latitude,longitude)
               VALUES (:longitude,:latitude)";

      $q = $conn->prepare($stmt);
      $results = $q->execute(array(
        ":longitude"=>$longitude,
        ":latitude"=>$latitude
     ));
      }
      exit();

如前所述,我的经纬度存储到数据库没有问题。但让它发送到我的mySQL数据库是我有困难做的事情。我使用这种方法是因为我正在为移动设备开发(准确地说是Cordova/Phonegap)。
这方面的任何帮助都是有利的。

最佳答案

如果有人有问题发送本地存储坐标…我可以让我的数据发送。。。我设置了ajax来发布引用本地存储中Cordova/Phonegaps getItem的新vars。我的代码如下。。。工作完美!希望这能帮助任何人实现同样的目标。

    var getlat = window.localStorage.getItem("latitude");
    var getlng = window.localStorage.getItem("longitude");
    $.ajax({
        type: "POST",
        url: 'http:myurl/dbUserLocation.php',
        data: { latitude : getlat, longitude : getlng },
        success: function(data)
        {
            alert("Location Data Sent!");
        },
        complete:function remove(){
            localStorage.removeItem("latitude");
            localStorage.removeItem("longitude");
        },
        error: function(){
            alert('Code 303A');
        }
    });
