asp.net mvc
前台代码：
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>TestUpload</title>
<script type="text/javascript" src="~/Scripts/jquery-1.10.2.min.js"></script>
</head>
<body>
<div>
<textarea id="txt"></textarea>
<form id="uploadForm" action="Upload/TestAjax" method="post" enctype="multipart/form-data">
<input id="File1" name="fileupload" accept="image/gif, image/jpeg" multiple="multiple" type="file" value="" />
<input id="btn" type="button" value="上传" />
</form>
</div>
</body>
</html>
<script type="text/javascript">
$(function () {
$("#btn").click(function () {
var formData = new FormData($("#uploadForm")[0]);
//var formData = $("#uploadForm");
$.ajax({
url: "/Upload/TestAjax",
data: formData,
type: "POST",
cache: false,
async: true,
contentType: false,
processData: false,
success: function (data) {
console.log(data);
},
error: function (data) {
console.log(data);
},
});
return false;
});
});
</script>
后台代码
public ActionResult TestUpload()
{
return View();
}
[HttpPost]
public ActionResult TestAjax()
{
if (Request.Files.Count > 0)
{
if (Request.Files.Count == 1)
{
HttpPostedFileBase file = Request.Files[0];
if (file.ContentLength > 0)
{
string title = string.Empty;
title = DateTime.Now.Ticks.ToString() + Path.GetExtension(file.FileName);
string path = "/upload/" + DateTime.Now.ToString("yyyyMMdd")+"/" + title;
path = System.Web.HttpContext.Current.Server.MapPath(path);
file.SaveAs(path);
return Json(new { status = true, url = path });
}
}
else
{
string[] urllist = new string[Request.Files.Count];
for (int i = 0; i < Request.Files.Count; i++)
{
HttpPostedFileBase file = Request.Files[i];
if (file.ContentLength > 0)
{
string title = string.Empty;
title = DateTime.Now.Ticks.ToString() +Path.GetExtension(file.FileName);
string path = "/upload/" + DateTime.Now.ToString("yyyyMMdd") + "/" + title;
path = System.Web.HttpContext.Current.Server.MapPath(path);
file.SaveAs(path);
urllist[i] = path;
}
}
return Json(new { status = true, url = urllist });
}
}
else
{
return Json(new { status = false, url = "", msg = "没有文件" });
}
return Json(new { status = false, url = "", msg = "" });
}
其实就是一个简单的ajax文件上传。我的要求是，执行成功不要刷新页面。
但是很奇怪的是，执行不成功时，代码不刷新，一旦执行成功就自动给我刷新了！！！跪求各位大大
