href图片链接下载点击 [英] href image link download on click

问题描述

我生成普通链接，例如:<a href="/path/to/image"><img src="/path/to/image"/></a>在网络应用中.

I generate normal links like: <a href="/path/to/image"><img src="/path/to/image" /></a> in a web app.

当我点击链接时，它会在新页面中显示图片.如果要保存图片，则需要右键单击它并选择另存为"

When I click on the link, it displays the picture in a new page. If you want to save the picture, then you need to right click on it and select "save as"

我不想要这种行为，我希望当我点击链接时弹出一个下载框，这是否可能仅使用 html 或 javascript?怎么样?

I don't want this behaviour, I would like to have a download box popping out when I click on the link, is that possible just with html or javascript? How?

如果不是，我想我将不得不编写一个 download.php 脚本并将其调用到以文件名作为参数的 href 中...?

If not I guess I would have to write a download.php script and call it into the href with the file name as parameter...?

推荐答案

<a download="custom-filename.jpg" href="/path/to/image" title="ImageName">
    <img alt="ImageName" src="/path/to/image">
</a>
