i have to do something and i have already a part of work. I want to insert longitude(long) and latitude(lat) in mysql database. found this code who gives me lon and lat

我必须做点什么，而且我已经完成了一部分工作。我想在mysql数据库中插入经度（长）和纬度（纬度）。发现这个代码给了我lon和lat

<!DOCTYPE html>
<html>
<body>

<p>Click the button to get your coordinates.</p>

<button onclick="getLocation()">Try It</button>

<p id="demo"></p>

<script>
    var x = document.getElementById("demo");

    function getLocation() {
        if (navigator.geolocation) {
            navigator.geolocation.getCurrentPosition(showPosition);
        } else { 
            x.innerHTML = "Geolocation is not supported by this browser.";
        }
    }

    function showPosition(position) {
        x.innerHTML = "Latitude: " + position.coords.latitude + 
            "<br>Longitude: " + position.coords.longitude;
    }
</script>

</body>

This code print long and lat, that i want is to get long and lat in php and run sql query behind.

这段代码打印long和lat，我想要的是在php中运行并运行sql查询。

Using ajax you can save latitude and longitude into the database. For this update your script as given below.

使用ajax，您可以将纬度和经度保存到数据库中。对于此更新，您的脚本如下所示。

function showPosition(position) {
    x.innerHTML = "Latitude: " + position.coords.latitude + 
    "<br>Longitude: " + position.coords.longitude;

    saveData(position.coords.latitude,position.coords.longitude);

}

function saveData(latitude,longitude){
        $.ajax({
        url: 'save_data.php', // Script to save latitude and longitude
        type: 'GET', 
        data: { latitude : latitude, longitude : longitude },
        dataType: "json",     
        success: function(result) {
            //Return result
        }
    });
}
