getPreviousDynamicPage( )
Gets the previous dynamic page URL.
Description
The getPreviousDynamicPage()
function can only be called on a dynamic page
dataset.
The function returns a Promise that is resolved to the relative URL of the
previous dynamic page or null
if there is no previous page.
The previous page is determined by the lexicographical order of the dynamic page relative URLs. You can see all of the relative URLs for a dynamic page by viewing the collection connected to the page.
URLs for items that do not match the dataset's filters are not returned.
For example, consider the following situation:
- You have a collection of employees that contains a boolean field named Active.
- Your dynamic page datset is filtered to only show employees where Active is true.
- Some of your dynamic page URLs include:
- employees/Alice
- employees/Bob
- employees/Cathy
If Bob is not an active employee, when you call getPreviousDynamicPage()
from Cathy's page, the returned Promise will resolve to "employees/Alice"
.
Pass the returned URL to the to()
function to
navigate to the previous dynamic page.
