href图像链接下载点击

问题描述

我生成正常链接，如：< a href =/ path / to / image>< img src =/ path / to / image/>< / a> ; 在网络应用程序中。

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，则需要右键单击并选择另存为

我不想要这个行为，我想要当我点击链接时，一个下载框弹出，是可能只是用html或javascript？如何？如果不是，我想我将不得不编写一个download.php脚本并将其称为href文件名作为参数？？

解决方案

 < a download =custom-filename.jpghref =/ path / to / imagetitle =ImageName> 
< img alt =ImageNamesrc =/ path / to / image> 
< / a> 
  

尚未完全支持 ，但您可以使用modernizr （在非核心检测）来检查浏览器的支持。

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

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"

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?

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...?

解决方案

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

It's not yet fully supported http://caniuse.com/#feat=download, but you can use with modernizr https://modernizr.com/download/?adownload-setclasses (under Non-core detects) to check the support of the browser.
