在JavaScript事件处理程序同步或异步调用 [英] Asynchronous or Synchronous calling of event handlers in javascript

问题描述

是事件处理程序同步或异步执行在JavaScript中？
这里是一个正显示出是同步执行的事件处理程序 JS斌。

Are event handlers executed synchronously or asynchronously in JavaScript? Here is JS bin which is showing that event handler is executed synchronously.

code：

$('#toclick').bind('custom', function() {
    for (var i=0; i<100000; i++) {}
    console.log('Inside click handler');
});

$('#toclick').trigger('custom');
console.log('Outside click handler');

Output:
Inside click handler
Outside click handler

这意味着，如果我们触发一个事件，它下面的code不会，除非所有的事件处理程序被执行处决。我说得对不对？

This means if we trigger an event, the code below it won't be executed unless all the event handlers are executed. Am I right ?

斌与多个事件处理程序

推荐答案

这是正确的。所有的事件处理程序同步并在绑定顺序解雇。

That's correct. All event handlers are fired synchronously and in order of binding.
