Why is my event listener written in Google Closure not working?

问题

I have a function in my Google Closure code with an event listener that aims to append HTML generated by a soy template to the body when the body loads:

/**
 * Constructs the home page.
 */
AppLoader.prototype.constructHomePage = function() {
  goog.events.listen(document.body, 'onload', function() {
      document.body.innerHTML = templates.home.main();});
}

(new AppLoader()).constructHomePage();

However, it does not work. Chrome Console also offers no errors. What I have tried is the below code, which uses the addEventListener function native to javascript.

... class instantiation
/**
 * Constructs the home page.
 */
AppLoader.prototype.constructHomePage = function() {
  document.body.innerHTML = templates.home.main();
}

document.body.addEventListener('load', function() {
  (new AppLoader()).constructHomePage();
}, false);

This latter method works, but does not use Closure at all, so I don't feel that it is reliable. Why is my event listener written in Google Closure not working?

回答1:

you should stop the browser events.

event.stopPropagation();

回答2:

You should attach it to the window object.

goog.events.listenOnce(
  window
, goog.events.EventType.LOAD
, function(){
    window.alert( 'Ready for ADVANCED_COMPILATION!' );
  }
);
