如何将javascript值插入sql数据库，这是Microsoft数据库

Question

hi i am tryign to create a store locator and i want to put the users latitude and longitude up into the data base how would i do this i am using javascript to get the results and im going to use php for the database this is the code i am using to get the users location

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



function showPosition1(position) {
var locations = [
    ['store1', -2.063150, 2.516503, 4],
    ['store2', -2.064824, 52.518436, 5],
    ['store3', -2.068214, 52.519898, 3],
    ['store4', -2.068558, 52.512769, 2],
    ['store5', -2.070875, 52.510758, 1]
];




lon1 = position.coords.longitude * 0.0174532925;
lat1 = position.coords.latitude * 0.0174532925;
i = 0;

while (i < locations.length) {
    function round(x) {
        return Math.round(x * 10) / 10;
    }
   x.innerHTML += "<br>Distance " + round(calcDist(lon1, lat1, locations[i][1] * 0.0174532925, locations[i][2] * 0.0174532925));
    i++;

}

}

all my code is working i just want to be able to put the lon 1 and lat1 into my database any ideas would be much appreciated thanks in advance

You would create another page that does your database insert.
Assuming you are using IIS - you write a page in C# or VB that reads the Request.QueryString["latitude"] & Request.QueryString["longitude"].
From there you can use standard .net code to update the SQL Server.

To send the data from browser to server:
On the client side (javascript) you would use the jQuery ajax method to call that page passing your data. eg

    $.ajax({
    url: 'url_to_server_page.aspx'
    , data: 'latitude=90&longitude90'})
    , success: function (data) { alert('data'); }
});

If you're not using ASP then only your language would change but the basic struture of how you send data to the server is the same - client page sending data to server page. This ajax example uses a default GET for simplicity but since you are updating a database you should do this as a POST.
