You've probably heard of iOS's dreaded 300ms tap delay. React's onClick attribute falls prey to it. Facebook's working on a solution in the form of TapEventPlugin, but it won't be made available until 1.0.

If you're reading this, you're probably working on a project that can't wait until they figure out how they want to publish it. This repo is for you.

When Facebook solves #436 and #1170, this repo will disappear.

var injectTapEventPlugin = require("react-tap-event-plugin");
injectTapEventPlugin();

See demo project for a complete working example.

var React = require("react");
var ReactDOM = require("react-dom");
injectTapEventPlugin = require("react-tap-event-plugin");
injectTapEventPlugin();

var Main = React.createClass({
  render: function() {
    return (
      <a
        href="#"
        onTouchTap={this.handleTouchTap}
        onClick={this.handleClick}>
        Tap Me
      </a>
    );
  },

  handleClick: function(e) {
    console.log("click", e);
  },

  handleTouchTap: function(e) {
    console.log("touchTap", e);
  }
});

ReactDOM.render(<Main />, document.getElementById("container"));

When a tap happens, the browser sends a touchstart and touchend, and then 300ms later, a click event. This plugin ignores the click event if it has been immediately preceeded by a touch event (within 750ms of the last touch event).

Occasionally, there may be times when the 750ms threshold is exceeded due to slow rendering or garbage collection, and this causes the dreaded ghost click.

The 750ms threshold is pretty good, but sometimes you might want to override that behaviour. You can do this by supplying your own shouldRejectClick function when you inject the plugin.

The following example will simply reject all click events, which you might want to do if you are always using onTouchTap and only building for touch devices:

var React = require('react'),
injectTapEventPlugin = require("react-tap-event-plugin");
injectTapEventPlugin({
  shouldRejectClick: function (lastTouchEventTimestamp, clickEventTimestamp) {
    return true;
  }
});

Use the demo project and it's README instructions to build a version of React with the tap event plugin included.
