发送JavaScript变量到PHP [英] Send JavaScript variable to PHP

问题描述

什么即时试图做的，是发送一个JavaScript变量到PHP函数。我正在开发一个jQuery Mobile的应用程序，你可以检查，当你达到一个特定的经度/纬度。但我有与发送的经度/纬度到PHP函数的问题。林把它发送到一个PHP函数，因为我也会做的，我已经保存在我的数据库中的经度/纬度的对比。

What im trying to do here is sending a JavaScript variable to a PHP function. What I'm developing is a jQuery Mobile App where you can check in when you reach a specific longitude/latitude. But I'm having problem with sending the longitude/latitude to the PHP-function. Im sending it to a PHP-function because im gonna do a comparison with the longitude/latitude that I've stored in my database.

下面是我的code。

        function testResults() {

            if(navigator.geolocation) {
                //Get the current position
                navigator.geolocation.getCurrentPosition(function(position) {
                    var latitude = position.coords.latitude;
                    var longitude = position.coords.longitude;
                    document.write("lat", latitude);
                    document.write('<br /><br />');
                    document.write("long", longitude);
                });
            } else {
                alert("Sorry... your browser does not support the HTML5 GeoLocation API");
            }

         //////////// Here I tried with jQuery/Ajax. I know that it's wrong.
        ////////////  Im putting it here so that it maybe clarifies what Im 
       ////////////   trying to do.

            $.post("checkLocation.php", {
                lat : latitude,
                longi : longitude
            }, function(data) {
                alert("Data Loaded: " + data);
            });

      ////////////////////////////////////////////////////////////////////

        }

        testResults();

我该如何解决这个问题？我试着使用JSON，但我没有得到它的工作。任何帮助将AP preciated。

How do I approach this problem? I've tried with JSON, but i didn't get it to work. Any help will be appreciated.

推荐答案

您要发送请求之前，你的地理位置回应

You're sending the request before you get the geolocation response

您需要做的是在回调中。

You need to do it inside the callback.
