add-one-dom-event-listener v1.0.2

依赖于add-dom-event-listener

但是同一个element只绑定一种event一次，不重复绑定

var addEventListener = require('add-one-dom-event-listener');
var handler = addEventListener(document.body, 'click', function(e){
  console.log(e.target); // works for ie
  
  console.log(e.nativeEvent); // native dom event
});
handler.remove(); // detach event listener
