触发从javascript自动下载不适用于页面加载 [英] trigger an automatic download from javascript doesn't work on page load

问题描述

我使用了链接的下载属性来下载文件。但是，当我从另一个方法触发click事件时，它不会下载该文件。为什么会这样？我已检查是否触发了click事件。这是我对jsfiddle的测试 - http://jsfiddle.net/6Fkb5/1/

I have used the download attribute of a link to download a file. However, when I trigger the click event from another method, it doesn't download the file. Why is that so? I have checked that the click event is being triggered. Here's my test on jsfiddle - http://jsfiddle.net/6Fkb5/1/

<a href="#" download="https://www.dropbox.com/s/shd31hvnsn0fd0v/Getting%20Started.pdf" id="testdownload">Test Download</a>

var count=0;
$('#testdownload').on('click', function(){
    count++;
    $('#log').append('<li>Click triggered ' + count + ' times</li>');
});


$('#testdownload').trigger('click');

推荐答案

试试这个：

$('#testdownload').get(0).click();

编辑：只是为了澄清这将触发本机点击事件而不是jQuery。

Just to clarify this will trigger a native click event instead of jQuery's.
