[−][src]Struct dominator::events::PopStateEvent
A PopStateEvent
is dispatched to the window every time the active history entry changes
between two history entries for the same document. If the history entry being activated was
created by a call to history.push_state()
or was affected by a call to
history.replace_state()
, the PopStateEvent
's state property contains a copy of the history
entry's state object.
Note that just calling history.push_state()
or history.replace_state()
won't trigger a
PopStateEvent
. The PopStateEvent
is only triggered by doing a browser action such as a
clicking on the back button (or calling history.back()
). And the event is only
triggered when the user navigates between two history entries for the same document.
Browsers tend to handle the PopStateEvent
differently on page load. Chrome and Safari always
emit a PopStateEvent
on page load, but Firefox doesn't.
Methods
impl PopStateEvent
[src]
pub fn state(&self) -> Value
[src]
The state object associated to the new history entry, if that entry was created with push_state or affected by replace_state.
Example usage:
let state: Option<MyStruct> = event.state().try_into().ok();
