Javascript - how to add Listener for krpano variable changed ?

Hi all,

I want to ask if it is possible to create a listener in javascript that would catch every change of a variable from the patch.

I inlude krpano via javascript. and I need to get the information in javascript (outside the krpano XML file) that the krpano variable has changed. How to achieve this please?

I am solving the problem of having a lot of functions in javascript to lighten the krpano. but I need them to communicate with each other. if a variable in patch changes, something must happen in javascript.

thanks in advance for any advice

Hi,

i declare in initvars some variable:

example :

embedpano({
...

initvars : {
test_variable : 1

}

})
in hotspot in XML i have declared : <hotspot name="test" ... url="../img_%$test_variable%.png" />

what i need to achieve is :

if the value of the variables changes, let the hotspot image also change.

but this will not happen to me. Therefore, I need to find out the information that the variable has changed and then I can change the url of the hotspot.
If there was a way to change the image after changing the krpano variable, that would be great. but I don't know if it is possible to achieve this if the value of the krpano variable changes outside of XML

Via XML -> hotspot on click action.

but i think i can/want update this variable too in ma Javascript code.

Thank you kme, your answer helped me a lot. well thank you :)
