jQuery download a zipfile from a button?
提问by FFish
Quite embarrassing how much time I spend trying to get to download a zipfile from a button....
很尴尬，我花了多少时间试图从按钮下载 zip 文件......
<button type='button' id='button-download'>download zipfile</button>
$("#button-download").live("click", function() {
$.get("http://localhost/admin/zip/002140.zip"); // doesn't work?
})
I need something bullet proof here, that's why I ask here, thanks.
我需要一些防弹的东西，这就是我在这里问的原因，谢谢。

Use a plain:
使用普通：
<a href="http://localhost/admin/zip/002140.zip" id="button-download">download zipfile</a>
link. Then it'll work fine (“bullet proof” even) without JavaScript available. It also offers more of the traditional affordances users might expect from a download link, such as right-click-save-as, or drag-and-drop.
关联。然后它会在没有 JavaScript 可用的情况下正常工作（甚至“防弹”）。它还提供了用户可能期望从下载链接获得的更多传统功能，例如右键单击另存为或拖放。
You can of course use CSS to make it look like a button instead of a link. But what it actuallyis, is a link. So that's how it should be marked up.
您当然可以使用 CSS 使其看起来像一个按钮而不是一个链接。但它实际上是一个链接。所以这就是它应该被标记的方式。

You should set the location.hrefproperty to cause navigation:
您应该设置该location.href属性以进行导航：
$("#button-download").live("click", function() {
location.href = "http://localhost/admin/zip/002140.zip";
});
You could also have a simple <a>element, styled as if it were a button, in that way even the users who have JavaScript disabled will be able to download the file.
你也可以有一个简单的<a>元素，样式就像一个按钮，这样即使禁用了 JavaScript 的用户也可以下载文件。

That is sending an AJAX request.
即发送 AJAX 请求。
I haven't tried this, but it should work in theory. If you try to go to a location of a file that is downloaded, it prompts you to download rather than take you to that page.
我没有试过这个，但理论上应该可以。如果您尝试转到已下载文件的某个位置，它会提示您下载而不是将您带到该页面。
<button type='button' id='button-download'>download zipfile</button>
$("#button-download").live("click", function() {
window.location = "http://localhost/admin/zip/002140.zip";
})

Bit late to the party but thought I'd share my solution as nobody else has.
参加聚会有点晚，但我想我会像其他人一样分享我的解决方案。
You can have the best of both worlds; a simple HTML link and a JS function, without losing the non-JS users.
你可以两全其美；一个简单的 HTML 链接和一个 JS 函数，不会丢失非 JS 用户。
<a id="download" href="http://www.example.com/download.zip">Download</a>
$("#download").on("click", function(e) {
// cancel the link's original functionality
e.preventDefault();
// do something before downloading
alert("Thanks for downloading!");
// download file
location.href = "http://www.example.com/download.zip";
});
