Want to change the style of the marker for the current event

HI everyone ,

I currently display all the location for the week on a map , but i would like to change the style of the marker for the current event .
Problem is , there is no distinction between all marker and there is no relation between location and event exept the id .
I don’t know how to do that in js.
Maybe someone can help me ?

Thanks
