注意 : See 事件冒泡和捕获 for more information on bubbling.

句法

var doesItBubble = event.bubbles;

值

A 布尔 ，其是 true if the event bubbles up through the DOM.

范例

function handleInput(e) {
  // Checks whether the event bubbles and ...
  if (!e.bubbles) {
    // ... passes the event along if does not
    passItOn(e);
  }
  // Already bubbling
  doOutput(e);
