javascript - 什么时候调用 "DOMNodeInserted"事件？

Question

DOMNodeInserted 当节点“被附加到”或“被附加”时调用事件？

我问这个是因为下面的代码:

function AddTextToContainer () {
    var textNode = document.createTextNode ("My text");
    var container = document.getElementById ("container");

    if (container.addEventListener) {
        container.addEventListener ('DOMNodeInserted', OnNodeInserted, false);
    }
    container.appendChild (textNode);
}

还有:

function AddTextToContainer () {
   var textNode = document.createTextNode ("My text");
   var container = document.getElementById ("container");

   if (textNode.addEventListener) {
       textNode.addEventListener ('DOMNodeInserted', OnNodeInserted, false);
   }
   container.appendChild (textNode);
}

两者 在 Chrome 中调用 OnNodeInserted。是错误吗？

Answer 1

这是来自 W3C

DOMNodeInserted
Fired when a node has been added as a child of another node. 
This event is dispatched after the insertion has taken place. 
The target of this event is the node being inserted.
Bubbles: Yes
Cancelable: No
Context Info: relatedNode holds the parent node

关键是 Bubbles: Yes - 这就是它也在容器上发射的原因。
