javascript - 具有特定路径的文件浏览器

Question

我正在构建一个文件 uploader 。但我想从服务器上的文件夹上传，因此浏览器的路径被限制为

C:\wamp\www\JSSoundRecorder\上传

如何指定html输入文件中的路径？ html代码:

<button id="id">Open</button>
<input id="yourinputname" type="file" name="yourinputname" style="display: none;" />

jquery 代码:

$('#id').on('click', function() {
$('#yourinputname').trigger('click');
});

由于安全原因，这是不可能的，某些浏览器甚至不允许您知道本地文件的路径，更不用说设置它了。

Some browsers have a security feature that prevents javascript from knowing your file's local full path. It makes sense - as a client, you don't want the server to know your local machine's filesystem. It would be nice if all browsers did this. https://stackoverflow.com/a/4851614/1817690
