正如@Stephen 提到的,您需要使用ajax 来创建文件夹。所以你可以有一个像这样的动作方法:
[HttpPost]
public JsonResult CreateDirectory()
{
//if location has folder called "Essential_Folder" it should allow to goto inside of this if condition
if (Directory.Exists(Server.MapPath("~/Content/Essential_Folder/")))
{
Directory.CreateDirectory(Server.MapPath(string.Format("~/Content/Essential_Folder/NewDir_{0}",
DateTime.Now.Millisecond)));
return Json("OK");
}
return Json("NO");
}
你的ajax调用应该是这样的:
<script type="text/javascript">
$('.btn').click(function() {
$.ajax({
url: "@Url.Action("CreateDirectory")",
type: "POST",
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (response) {
alert(response.responseText);
},
success: function (response) {
if (response === 'OK')
alert("Directory has been created");
else
alert("errro");
}
});
});
</script>
