数据中下载文件的文件名：Application / octet-stream; [英] Filename of downloaded file in data:Application/octet-stream;

问题描述

 < input type =button$ 
我试图使用数据uri以下列方式下载文件： b $ b onclick =window.location.href ='data：Application / octet-stream; content-disposition：attachment; filename = file.txt，$ {details}'
 value =Download/> gt ; 
  

问题是下载的文件总是被命名为'Unknown'，无论我尝试使用
文件名。这是给文件起一个名字的正确方法吗？或者其他的东西需要被
完成？

解决方案

这是解决方案，您只需添加<$ c




code $ a pre> < a href =data：application / csv; charset = utf-8，Col1％2CCol2％2CCol3％0AVal1％2CVal2％2CVal3％0AVal11％2CVal22％2CVal33％0AVal111％2CVal222％ 2CVal333
download =somedata.csv>示例< / a>


另一个解决方案是使用JQuery / Javascript

锚的下载属性

I am trying to download a file using data uri in following manner:

<input type="button"
  onclick="window.location.href='data:Application/octet-stream;content-disposition:attachment;filename=file.txt,${details}'"
  value="Download"/>

The problem is that the downloaded file is always named 'Unknown', whatever I try to use as filename. Is this the correct way to give the file a name ? or something else needs to be done ?

解决方案

Here's the solution, you just have to add a download attribute to anchor tag a with desired name

<a href="data:application/csv;charset=utf-8,Col1%2CCol2%2CCol3%0AVal1%2CVal2%2CVal3%0AVal11%2CVal22%2CVal33%0AVal111%2CVal222%2CVal333"
  download="somedata.csv">Example</a>

Another solution is to use JQuery/Javascript
