Is There Page Return Button

[raining010]

Hi, Admin

 

does DF supply an action, that could return to the previous page? I didn't find it. No matter which page comes to this one, while click this button, it could return to the previous page.

 

Thanks

There isn't a built in function to do precisely that, but we added the push() and pop() functions on variables to make it easy to implement yourself.  Basically create two sequences, setPage() and popPage().  SetPage() looks like this:

 

function setPage(string newPage)

   global string pageStack // declare just in case

   pageStack.push(page.strCurrentPage)

   page.strCurrentPage = newPage

 

then popPage() looks like this:

 

page.strCurrentPage = pageStack.pop()

 

That's it.  Now whenever you want to change the page, call setPage(), and whenever you want to go back, call popPage().
