In 22order to make use of the announcer, it is best to request its availability 23in the announcing element. 24 25Example: 26 27 Polymer({ 28 29 is: 'x-chatty', 30 31 attached: function() { 32 // This will create the singleton element if it has not 33 // been created yet: 34 Polymer.IronA11yAnnouncer.requestAvailability(); 35 } 36 }); 37 38After the `iron-a11y-announcer` has been made available, elements can 39make announces by firing bubbling `iron-announce` events. 40 41Example: 42 43 this.fire('iron-announce', { 44 text: 'This is an announcement!' 45 }, { bubbles: true }); 46 47Note: announcements are only audible if you have a screen reader enabled. 48 49 50
