updating variables without refreshing

So I'm using an interface with multiple tabs co-depending on one another, but when i make changes in one, in order to see the changes I need to refresh my browser, is there any way possible to update those variables without refreshing the browser? for instance i have a local variable that receives data from a CDT and in another tab I delete a row from my CDT but if I don't refresh the page, that row is still displaying. Any help?
