我有一个简单的HTML上传表单，我想指定一个默认的扩展名（例如* .drp）。我读过这样做的方式是通过输入标签的ACCEPT属性，但我不知道如何。
I have a simple HTML upload form, and I want to specify a default extension ("*.drp" for example). I've read that the way to do this is through the ACCEPT attribute of the input tag, but I don't know how exactly.
<form enctype="multipart/form-data" action="uploader.php" method="POST"> Upload DRP File: <input name="Upload Saved Replay" type="file" accept="*.drp"/><br /> <input type="submit" value="Upload File" /> </form>
EditI know validation is possible using javascript, but I would like the user to only see ".drp" files in his popup dialog. Also, I don't care much about server-side validation in this application.
For specific formats like yours ".drp ". You can directly pass that in accept=".drp" it will work for that.
<input name="Upload Saved Replay" type="file" accept=".drp" /> <br/>
