[Javascript] Div targeting

[dev at qroute.net]

Can "DIV"s be an alternative frames ?
Instead of creating a traditional frame say with 2 rows I want to create two
divisions.
Since I can create a position for each division and set the ability to
scroll content in divisions, the end result would appear the same as a 2 row
frame.

My question is how do you upload the contents of one division from another ?
How does the targeting work ?
