由于项目开发使用到jquery validate 在校验 上传文件的时候 发现 自带的校验功能丰富，且好用。但是有些MIME由于不经常使用不太方便查看所以在此做个记录
<body>
<form class="cmxform" id="fileForm" method="post" action="">
<fieldset>
<legend>选择指定类型的文件？</legend>
<p>
<label for="file1">选择一个纯文本文件（例如 *.txt）</label>
<input type="file" id="file1" name="file1" class="required" accept="text/plain" />
</p>
<p>
<label for="file2">选择任何图像文件</label>
<input type="file" id="file2" name="file2" class="required" accept="image/*"/>
</p>
<p>
<label for="file3">选择一个 PDF 或 EPS 文件</label>
<input type="file" id="file3" name="file3" class="required" accept="image/x-eps,application/pdf"/>
</p>
<p>
<label for="file4">选择任何音频或图像文件</label>
<input type="file" id="file4" name="file4" class="required" accept="image/*,audio/*"/>
</p>
<p>
<label for="file5">选择一个或多个纯文本文件（例如 *.txt）</label>
<input type="file" id="file5" name="file5" class="required" multiple accept="text/plain" />
</p>
<p>
<input class="submit" type="submit" value="提交"/>
</p>
</fieldset>
</form>
</body>
</html> 此例子参考w3cschool。
