我建议使用下载属性而不是jQuery:

<a href="your_link" download> file_name </a>

这将下载您的文件，而不需要打开它。

如果您已经在使用jQuery，可以利用它生成一个较小的代码片段 jQuery版本的Andrew的回答:

var $idown;  // Keep it outside of the function, so it's initialized once.
downloadURL : function(url) {
  if ($idown) {
    $idown.attr('src',url);
  } else {
    $idown = $('<iframe>', { id:'idown', src:url }).hide().appendTo('body');
  }
},
//... How to use it:
downloadURL('http://whatever.com/file.pdf');

function downloadURI(uri, name) 
{
    var link = document.createElement("a");
    // If you don't know the name or want to use
    // the webserver default set name = ''
    link.setAttribute('download', name);
    link.href = uri;
    document.body.appendChild(link);
    link.click();
    link.remove();
}

检查您的目标浏览器是否能够顺利运行上面的代码片段:http://caniuse.com/#feat=download

Firefox和Chrome测试:

var link = document.createElement('a');
link.download = 'fileName.ext'
link.href = 'http://down.serv/file.ext';

// Because firefox not executing the .click() well
// We need to create mouse event initialization.
var clickEvent = document.createEvent("MouseEvent");
clickEvent.initEvent("click", true, true);

link.dispatchEvent(clickEvent);

这实际上是firefox的“chrome”方式解决方案(我没有在其他浏览器上测试过，所以请留下关于可编译性的评论)

也许只是让你的javascript打开一个只下载文件的页面，比如当你把一个下载链接拖到一个新选项卡:

Window.open("https://www.MyServer.
Org/downloads/ardiuno/WgiWho=?:8080")

打开窗口，打开一个自动关闭的下载页面。

let args = {"data":htmlData,"filename":exampleName}

创建HTMl文件并下载

window.downloadHTML = function(args) {
var data, filename, link;
var csv = args.data;
if (csv == null) return;
filename = args.filename || 'report.html';
data = 'data:text/html;charset=utf-8,' + encodeURIComponent(csv);
console.log(data);
link = document.createElement('a');
link.setAttribute('href', data);
link.setAttribute('download', filename);
document.body.appendChild(link);
link.click();
document.body.removeChild(link);}

创建并下载CSV文件

window.downloadCSV = function(args) {
var data, filename, link;
var csv = args.data;
if (csv == null) return;
filename = args.filename || 'report.csv';
if (!csv.match(/^data:text\/csv/i)) {
    csv = 'data:text/csv;charset=utf-8,' + csv;
}
data = encodeURI(csv);
link = document.createElement('a');
link.setAttribute('href', data);
link.setAttribute('download', filename);
document.body.appendChild(link);
link.click();
document.body.removeChild(link);

}
