js怎么实现点击下载文件?

js实现点击下载文件的方法:

实现方法

var link = document.createElement('a');
link.setAttribute("download", "");
link.href = "you file url";
link.click();
Copy after login

解释:创建一个a标签,然后设置 download 属性,这个是重点,有这个属性才能下载,然后设置下载的链接。

在网上找了很多的方法,基本就是通过下面方法打开:

window.location.href="你的url"; 
 
window.open("你的url")
Copy after login

但是文件是 txt 或者 img 的话,那么谷歌浏览器就会直接打开这些文件。
