使用委托的单击按钮下载文件JQuery [英] Download file JQuery with delegated click button

问题描述

已解决:查看下面标记为已解决的答案.谢谢.

SOLVED: View the answer below marked SOLVED. Thanks.

我正在尝试从单击时由url指定的位置下载文件.我正在使用委托，但是单击按钮时，浏览器将导航到文件的位置并显示内容.我希望点击触发浏览器的下载对话框.

I am trying to download a file from location specified by url on click. I am using a delegate but when the button clicks the browser navigates to the location of the file and displays the contents. I want the click to trigger the browser's download dialog.

这是代码:

$('#left').delegate("a", "click", function(event){
    //alert("CLICKED");

    event.preventDefault();
    window.location.href = url;

});

有关此问题的所有帖子都说要使用"event.preventDefault();"但这对我不起作用.有人有什么建议吗?

All posts regarding this question says to use the "event.preventDefault();" but that does not work for me. Does anyone have any suggestions?

推荐答案

您可能需要更改服务器端(如果可以).

You may need to change the server side (if you are able to).

http响应必须包含标头:

The http response must contain the header:

Content-disposition: attachment; filename=fname.ext

因此，浏览器知道必须打开下载对话框.否则，浏览器将尝试打开/预览它.

So the browser knows that it must open the download dialog. Otherwise the browser will try to open/preview it.
