将内容添加到DOM计数总页面加载时间？

Question

I mean if I append some contents like this: 我的意思是如果我附加一些这样的内容：

<body>
 //contents
 <script>body.appendChild('<img src="new.png">');
 // other contents
</body>

the browser will fire window.onload considering only the original html or it will take in consideration the load of the new image too? 浏览器会只考虑原始的html来激活window.onload，还是会考虑到新图像的负载？ ( new.png ) ? （ new.png ）？

Answer 1

Besides that code/markup being incorrect, it will consider the new image. 除了代码/标记不正确之外，它还会考虑新的图像。 To append it to the DOM will be to download whatever the src attribute points to. 将它附加到DOM将是下载src属性指向的任何内容。

However, if this code was placed inside of a window.onload = function() { ... } , then it wouldn't be considered because its download would not occur until your window was loaded. 但是，如果此代码放在window.onload = function() { ... } ，则不会考虑它，因为在加载窗口之前不会进行下载。

Here is the code that would actually work... 这是实际可行的代码......

var img = new Image;

img.src = 'http://www.gravatar.com/avatar/3535689c965d66db3d2a936ced96192a?s=32&d=identicon&r=PG';
img.alt = 'Example';

document.body.appendChild(img);
