cap*_*gon 0 html javascript dom javascript-events
我想"抓住" <body>创造的第一个时刻.我试过用DOMNodeInserted/ DOMNodeInsertedIntoDocument.这是我的代码:
<html>
<head>
<script>
document.addEventListener("DOMNodeInserted", handleDomInserted, true);
document.addEventListener("DOMNodeInsertedIntoDocument", handleDOMNodeInsertedIntoDocument, true);
function handleDOMNodeInsertedIntoDocument(e) {
console.log(e);
}
function handleDomInserted(e) {
console.log(e);
}
</script>
</head>
<body>
<div id="foo">
<span id="bazz"></span>
</div>
</body>
</html>
为什么这些函数永远不会被调用？
谢谢!
代码是正确的,但是当浏览器最初解析HTML时,不会触发JavaScript事件.JS evens只会在JS完成DOM操作时触发.
例如,如果将以下内容添加到代码示例中,则会触发事件:
<script>
var d = document.createElement('div');
d.innerHTML = 'test';
document.body.appendChild(d);
</script>
