Pass value of a variable from javascript to asp.net mvc

[manugm_1987]

Hello everyone,

I am very new to asp.net and asp.net mvc as well. I am stuck with the following problem please help. I have the following javascript

<script type="text/javascript">
        var allMarks = [];
        google.load("maps", "2");
        var geocoder;
       var lat;
        function initialize() {
            var map = new google.maps.Map2(document.getElementById("map"));
            map.setCenter(new google.maps.LatLng(37.4419, -122.1419), 10);
            map.setUIToDefault();
            GEvent.addListener(map, "click", function (overlay, latlng) {
                if (latlng) {
                    var marker = new GMarker(latlng);
                    allMarks.push(latlng);
                    map.addOverlay(marker);
                    marker.openInfoWindow(latlng.toString());
                    lat = latlng.toString();
              }
            });
           
            geocoder = new google.maps.Geocoder();
        }
        google.setOnLoadCallback(initialize);
 
    </script>

Now how can i pass lat variable value in javascript to my asp.net mvc actionresult method in the controller. The method is like

public ActionResult GetValues(string Latitude)
{
     //Get the value from javascript, process the value here
}

Thank you

I've used hidden fields on the page to do this. Others may have a better way but this has worked OK for me before. Include a label as a hidden field on the page and write the variable into it using javascript.
Your .Net code can then read from the label, obtaining the variable.

Thanks for the reply. I am using asp.net MVC will this hidden fields work for MVC as well.

The best solution is use Json string and pass that string to your action result method.
