没有。

肯定有。


document.location.href =''someOtherPage .html'';


我敢打赌停止在上一页加载图片。


或者，遍历图像集合并将所有src属性设置为'''';

它将停止下载它们。

为什么你问？

也许是因为他想知道？

当然可以，但是如果你考虑一下，OP也不大可能是

想要停止加载当前文档。

或者，循环遍历images集合并将所有src属性设置为'''';
它将停止下载它们。

在文档加载完成之前，你无法可靠地访问DOM树，包括document.images

集合，所以你不能

可靠地防止图像加载。


这让我们留下：不。（惊喜！）

Hi,

Is there some way in JavaScript to stop the downloading of pictures from a
web page?

Thank you.

No. Why do you ask?

Sure there is.

document.location.href = ''someOtherPage.html'';

I bet that stops the images from loading in the previous page.

Or, loop through the images collection and set all src properties to '''';
and it will stop downloading them.
Why do you ask?

Maybe because he wanted to know?

Sure, but if you think about it, it is highly unlikely that the OP also
wants to stop the current document from being loaded.

You cannot reliably access the DOM tree, including the document.images
collection, before the document has finished loading, so you cannot
reliably prevent the images from loading.

Which leaves us with: No. (Surprise!)
