Hi,
it depends how your java classes look like.
If you have a class like this one:
public class Coordinates {
private double lat;
private double lng;
}
You could have a list in your acton:
public class SomeAction {
private List coordinates;
...
public List getCoordinates() {
return coordinates;
}
}
In a JSP you could access coordinates like this:
var flightPlanCoordinates = [
{lat: ,
lng: },
]
Be aware that this is just a very simple example. You should adjust it to
your app.

Christoph

I'd rather use a JSON endpoint instead of directly populating such
variable in a page.

Struts 2.3.28.1 - Populate Java Property from Controller inside JavaScript
Hi all,
First of all, greetings, from Brazil.
I would like to populate this Java Script variable with name
*flightPlanCoordinates
*from a Action Controller.
var flightPlanCoordinates = [
{lat: -23.533592, lng: -46.742744},
{lat: -23.533592, lng: -46.742744},
{lat: -23.533870, lng: -46.742804},
{lat: -23.533978, lng: -46.742890}
];
Whats the best approach to do? I how can I use tag libs from Struts to
mount this *flightPlanCoordinates ?*
Thanks in advance,
Bisconcini
