input 添加 webkitdirectory 属性即可上传文件夹，使用 webkitRelativePath 获取到相对路径，截取字符串拿到文件名
<input type="file" onchange="selectFolder(event)" webkitdirectory /> |
<script type="text/javascript"> | |
function selectFolder(e) { | |
var theFiles = e.target.files; | |
var relativePath = theFiles[0].webkitRelativePath; | |
var folder = relativePath.split("/"); | |
alert(folder[0]); | |
} | |
</script> |
