how to pass form values from javascript to jsp page

开发者 https://www.devze.com 2023-01-24 07:08 出处：网络

This is my sample html page which contains inline javascript which calculates the geocode and tries to return the latitude and longitude .But my question is how to submit all the form values with latitude and longitude returned from showlocation function to submitform.jsp page and display latitude value in jsp page .

                if (!response || response.Status.code != 200) {
                    alert("Sorry, we were unable to geocode the first address");

                }
                else {
                    var lat1 = response.Placemark[0].Point.coordinates[1];
                    var lng1 = response.Placemark[0].Point.coordinates[0];

                    return {latitude: lat1, longitude: lng1};

   String Latitude=request.getParameter("Latitude");
    out.println("latitude is :"+request.getParameter("Latitude"));

one way directly append it in url like myJsp.jsp?lat=value&lon=value GET,

another way is to keep a hidden param and set lat , lon in it and POST it.
