问题描述
我正在使用纯Javascript编写文本编辑器。我希望这样当用户点击保存按钮时,编辑器会下载该文件。我已经部分工作了:
I'm working on a text editor in pure Javascript. I'd like it so that when the user clicks the 'Save' button, the editor downloads the file. I've already got this partly working:
uriContent = "data:application/octet-stream," + encodeURIComponent(codeMirror.getValue());
newWindow=window.open(uriContent, 'filename.txt');
文件下载,但问题是该文件名为download。
The file downloads, but the problem is that the file is named 'download'.
问题:我怎样才能将文件名更改为我想要的任何内容,例如 filename.txt
?
Question: How could I change the name of the file to be anything I want, e.g filename.txt
?
推荐答案
用锚链接替换保存按钮并设置新的动态下载
属性。适用于Chrome和Firefox:
Replace your "Save" button with an anchor link and set the new download
attribute dynamically. Works in Chrome and Firefox:
var d = "ha";
$(this).attr("href", "data:image/png;base64,abcdefghijklmnop").attr("download", "file-" + d + ".png");
这是一个工作示例,名称设置为当前日期:
Here's a working example with the name set as the current date: http://jsfiddle.net/Qjvb3/
