aura:locationChange

This event is automatically fired when the hash part of the URL has changed.

Use an <aura:handler> tag to react to a hash value change. A component can have only one <aura:handler event="aura:locationChange"> tag to handle this event.

1<aura:handler event="aura:locationChange" action="{!c.update}"/>

This client-side controller handles the aura:locationChange event. In this example, the handler is wired to the update action.

1({
2    update : function (component, event, helper) {
3        // Get the new hash from the event
4        var loc = event.getParam("token");
5        // Do something else
6    }
7})
