Detect change variable

[matija]

You mean from an IntraWeb event?

You need to add JavaScript to deal with it:

For instance, in a Callback call, you should use:

WebApplication.CallbackResponse.AddJavaScriptToExecute('MyIndex = 3');

This will be executed when the request is received by the browser.

If that's not what you want, please add more details to your question

My case:

Create OpenLayers Map: Intraweb -> JS:='MyMap(markers);' -> AddToInitProc(JS);

if click to marker -> change var MyIndex in Javascript

I have to say now it has changed this MyIndex and return this variable?
