Fastclick for Quasar Framework

This is a fork of the original Fastclick and is being used and maintained by Quasar Framework.
This is injected only for iOS platform (PWA or Cordova) and assumes you're already on that platform.

FastClick is a simple, easy-to-use library for eliminating the 300ms delay between a physical tap and the firing of a click event on mobile browsers. The aim is to make your application feel less laggy and more responsive while avoiding any interference with your current logic.

Compatibility

• iOS 7+ platform, on a Quasar PWA or Quasar Cordova

Usage

import Fastclick from '@quasar/fastclick'
FastClick()

Advanced

Ignore certain elements with needsclick

Sometimes you need FastClick to ignore certain elements. You can do this easily by adding the needsclick class.

<a class="needsclick">Ignored by FastClick</a>

Use case 1: non-synthetic click required

Internally, FastClick uses document.createEvent to fire a synthetic click event as soon as touchend is fired by the browser. It then suppresses the additional click event created by the browser after that. In some cases, the non-synthetic click event created by the browser is required, as described in the triggering focus example.

This is where the needsclick class comes in. Add the class to any element that requires a non-synthetic click.

Use case 2: Twitter Bootstrap 2.2.2 dropdowns

Another example of when to use the needsclick class is with dropdowns in Twitter Bootstrap 2.2.2. Bootstrap add its own touchstart listener for dropdowns, so you want to tell FastClick to ignore those. If you don't, touch devices will automatically close the dropdown as soon as it is clicked, because both FastClick and Bootstrap execute the synthetic click, one opens the dropdown, the second closes it immediately after.

<a class="dropdown-toggle needsclick" data-toggle="dropdown">Dropdown</a>

Examples

FastClick is designed to cope with many different browser oddities. Here are some examples to illustrate this:

• basic use showing the increase in perceived responsiveness
• triggering focus on an input element from a click handler
• input element which never receives clicks but gets fast focus
