manipulating frame url by script

[Erwin van der Zwart]

Hi Uwe,

Create a frame and give it the additional class "position" and create 3 objects where your LON, LAT and ZOOM variables are written to and create this custom JS:

Code:

$(function(){
 if (typeof grp != 'undefined') {
   grp.listen('40/1/15', function(object, state) {
     var LON = grp.getvalue('40/1/15') || 0;
     var LAT = grp.getvalue('40/1/16') || 0;
     var ZOOM = grp.getvalue('40/1/17') || 15;
     $('.position').find('iframe').attr('src', 'http://osmand.net/go.html?lat=' + LAT + '&lon=' + LON + '&z=' + ZOOM)
   }, true);
 }
});

$(function(){
 if (typeof grp != 'undefined') {
   grp.listen('40/1/16', function(object, state) {
     var LON = grp.getvalue('40/1/15') || 0;
     var LAT = grp.getvalue('40/1/16') || 0;
     var ZOOM = grp.getvalue('40/1/17') || 15;
     $('.position').find('iframe').attr('src', 'http://osmand.net/go.html?lat=' + LAT + '&lon=' + LON + '&z=' + ZOOM)
   }, true);
 }
});

$(function(){
 if (typeof grp != 'undefined') {
   grp.listen('40/1/17', function(object, state) {
     var LON = grp.getvalue('40/1/15') || 0;
     var LAT = grp.getvalue('40/1/16') || 0;
     var ZOOM = grp.getvalue('40/1/17') || 15;
     $('.position').find('iframe').attr('src', 'http://osmand.net/go.html?lat=' + LAT + '&lon=' + LON + '&z=' + ZOOM)
   }, true);
 }
});

This will update the URL in the frame as soon as one of the 3 object values are changing, it happens client side so no refresh of the client is needed.

BR,

Erwin
