How to update Router Component VL layout from parent/other page?

I have a mian page = home,
and a Router Component VL inside of this page,
VL cache:false,

I have a button with fun in the page home:


it is working, but scroll back to this #VL-download-2 will showup again.

cuz cache must be:false,
so, is there anyway to change div’s css from other page workin $setState??
