how to only get nodes on real roads way via overpass api

as the title shows, I want to get the OSM nodes data, which are on roads.
For roads, we can define it as the Way feature as highway tag. (I found this tip from a previous post).
How to do that?

EDIT; find the solution by myself:
way[highway](50.7460,7.170,50.7461,7.171);node(w);

the above query will output the all the nodes on the ways tagged as highway and within the bounding box. The key part is node(w). For more information, you can go to this osm wiki:
