Can be used to listen to tap evens (i.e. click/touch), preventing their
bubbling, or preventing normal execution. To stop either bubbling or
normal execution, callback should explicitly return false. By default,
bubbling and normal execution is not prevented.
onTap() adds a listener to a click or touch event to element wrapped
with event helper.
captureTap() installs a capture phase listener and callback returning
false at that moment intercepts tap before any action is taken by other
listeners (i.e. PolyGerrit buttons).
Sample code
``` js
Gerrit.install(plugin => {
plugin.hook('reply-text').onAttached(element => {
if (!element.content) { return; }
plugin.eventHelper(element.content).onTap(() => {
console.log('reply test tapped!');
});
plugin.eventHelper(element.content).captureTap(() => {
// Prevent onTap() handler from being called.
return false;
});
});
});
```
