[英]Trigger a browser download with JQuery
My goal is to let a user download a PDF from my server. 我的目标是让用户从我的服务器下载PDF。 The most common approach to this would be to simply have a link with a download attribute like so
最常见的方法是像这样简单地拥有一个带有下载属性的链接
<a href="http://mysource.pdf" download>click here</a>
The problem with this is that I cannot monitor the download or have a callback when it is finished. 这样做的问题是我无法监视下载或完成下载时出现回调。 The browser just hangs until the request is processed and suddenly pops up a download when it is done.
浏览器将一直挂起,直到处理完请求为止,并在完成后突然弹出下载。 So now I am getting pdf data from a server with AJAX and want to download the data via the browser.
因此,现在我正在使用AJAX从服务器获取pdf数据,并希望通过浏览器下载数据。
So I have something along the lines of 所以我有一些类似的东西
$.get("http://mysource.pdf", (data) ->
#need to somehow trigger a download with this data
)
I've been searching for a while to no avail. 我一直在寻找无济于事。 Any help is appreciated.
任何帮助表示赞赏。 Thanks!
谢谢!
--edit To clarify why this is not a duplicate, I am asking about triggering a download on data, not a local file. --edit为了弄清为什么它不是重复的,我询问触发数据下载,而不是本地文件下载。
$('a').click(function(event) {
event.preventDefault();
$.get("http://mysource.pdf", (data) ->
window.location.href = $(this).attr('href');
)
});
