如何提示另存为选项供用户使用chrome下载文件？

问题描述

我有一种方法可以下载文件，只要该方法按预期运行，我只是看到IE用户在浏览器中的差异可以选择另存为文件，但是在chrome中，它可以直接下载文件，我们如何拥有该功能在chrome中，因此用户可以在保存文件时使用另存为选项，以便为文件命名？

I have method that is downloading file whenever this method called it is working as expected, I just see difference in browser in IE user has option to save As file but in chrome it directly download the file , How can we have that feature in chrome so user can use Save as option while saving the file so they can name the file ?

ctrl.js

function deleteFile(filename){
    DitFactory.getFile(filename).then(function(response,$window){
        console.log('data for download', response);
        var data = JSON.stringify(response.data);
        var blob = new Blob([data], { type: 'text/plain;charset=utf-8' });
        FileSaver.saveAs(blob, 'server.log');
        socket.emit('stopRecording',$scope.filename);
    });
}

推荐答案

您要问的是'不可能的。

这是用户偏好设置

What you are asking isn't possible.
It's a user preference

ref：

唯一可以做的就是让用户在保存

The only thing you can do is letting the user rename server.log inside a input element or a window.prompt before saving

saveAs(blob, prompt('Filename?', 'server.log') || 'server.log');
