The dccLocation
component represents the location or address bar in your web
browser. Through its href
, pathname
, search
and hash
properties
you can access different portions of the URL that the app is loaded on.
See the URLs & Multipage Apps chapter for more details.
For example, given the URL http://127.0.0.1:8050/page-2?a=test#quiz
:
href
= "http://127.0.0.1:8050/page-2?a=test#quiz"
pathname
= "/page-2"
search
= "?a=test"
hash
= "#quiz"

id
(character; required):
The ID of this component, used to identify dash components in
callbacks. The ID needs to be unique across all of the components in
an app.
pathname
(character; optional):
pathname in window.location - e.g., “/my/full/pathname”.
search
(character; optional):
search in window.location - e.g., “?myargument=1”.
hash
(character; optional):
hash in window.location - e.g., “#myhash”.
href
(character; optional):
href in window.location - e.g.,
“/my/full/pathname?myargument=1#myhash”.
refresh
(a value equal to: ‘callback-nav’ | logical; default TRUE
):
Use True
to navigate outside the Dash app or to manually refresh a
page. Use False
if the same callback that updates the Location
component is also updating the page content - typically used in
multi-page apps that do not use Pages. Use ‘callback-nav’ if you are
updating the URL in a callback, or a different callback will respond
to the new Location with updated content. This is typical with
multi-page apps that use Pages. This will allow for navigating to a
new page without refreshing the page.
