一、前端cshtml代码
<tr>
<td width="130" align="right">添加附件：</td>
@using (Html.BeginForm("FileUp", "Detail", FormMethod.Post, new { enctype = "multipart/form-data", id = "formFileUpload" }))
{ <td>
<input name="file" type="file" value="浏览..." id="uploadFile" style="display: none;" />
<input type="text" class="fj_nr" id="filePath" />
</td>
<td>
<input type="button" value="浏览..." class="fh_btn" id="btnSee">
<input type="submit" value="上传" class="fh_btn" id="btnUploadFile" />
</td>
}
</tr>
<tr id="attachMents">
</tr>
二、JS代码
(function () {
var replyJs = replyJs || {};
replyJs.unitls = (function () {
var controller = '/RenosData.Fax.Web/Detail';
var homeController = '/RenosData.Fax.Web/Home';
//传真回复
var replyFax = function () {
//浏览附件
$("#btnSee").bind("click", function (e) {
$("#uploadFile").click();
});
//上传附件
$("#uploadFile").bind("change", function (e) {
$("#filePath").val($("#uploadFile").val());
});
$("#btnUploadFile").click(function () {
addAttachment();
return false;
});
//删除传真附件
$("#btnDelAttach").live("click",function () {
$.ajax({
url: controller + '/DelAttachment',
type: 'post',
//dataType: 'json',
data: "{file:'" + $(this).attr("filename") + "'}",
contentType: 'application/json; charset=utf-8',
success: function (data) {
if (data.status == "success") {
$("#attachMents").empty();
} else {
alert(data.message);
}
},
error: function (err) {
alert(err.toString());
}
});
});
//发送传真
$("#btnSendFax").click(function () {
addFaxToDb("send");
});
};
//上传附件
var addAttachment = function () {
if (!$("#filePath").val()) {
alert("请选择需要上传的文件!");
return;
}
//function showRequest(formData, jqForm, options) {
// //alert('发送前');
// return true;
//}
//function showResponse(responseText, statusText) {
// //alert('发送后');
//}
//var options = {
// //target: '#outputdiv',
// beforeSubmit: showRequest,
// success: showResponse
//};
//$(this).ajaxSubmit(options);
$("#formFileUpload").ajaxSubmit({
dataType: 'json',
beforeSend: function (xhr) {
},
success: function (data) {
if (data) {
if (data.message == "success") {
$("#filePath").val("");
$("#attachMents").empty().append("<td width='130' align='right'>已上传附件：</td><td><label id='lblFileName'>" + data.fileOldName + "</label></td><td><input type='button' value='删除' class='fh_btn' id='btnDelAttach' filename='" + data.fileName + "' filesize='" + data.fileSize + "'></td>");
} else {
alert(data.message);
}
}
},
complete: function () {
}
});
return;
};
//传真状态：发送or保存
var back = function () {
window.history.go(-1);
};
return {
replyFax: replyFax,
};
}());
$(function () {
replyJs.unitls.replyFax();
});
})(jQuery);
三、Controller代码
/// <summary>
/// 添加附件
/// </summary>
/// <returns></returns>
[HttpPost]
public ActionResult FileUp()
{
HttpPostedFileBase uploadFile = Request.Files[];
var fax = new FaxModel();
if (uploadFile == null || uploadFile.ContentLength == )
{
fax = new FaxModel() { Message = "请选择上传附件！", Attachment = null };
return Json(new { message = fax.Message });
}
//if (uploadFile.ContentLength > 20971520)
//{
// fax = new FaxModel() { Message = "请上传20MB以内的附件！", Attachment = null };
// return View("NewFax", fax);
//}
try
{
var newFileName = Guid.NewGuid() + "_" + uploadFile.FileName; ;
string attachFilePath = WebConfig.Attachment;
if (!Directory.Exists(attachFilePath))
Directory.CreateDirectory(attachFilePath);
string filePath = Path.Combine(attachFilePath, newFileName);
uploadFile.SaveAs(filePath);
var attachment = new FileAttachmentModel()
{
FileName = newFileName,
FileLength = (uploadFile.ContentLength * 1.0 / ).ToString("0.00"),
FilePath = filePath,
FileOldName = uploadFile.FileName,
FileSize = uploadFile.ContentLength
};
fax = new FaxModel() { Attachment = attachment };
ViewBag.FaxMsg = uploadFile.FileName;
return Json(new { message = "success", fileOldName = attachment.FileOldName, fileSize = attachment.FileSize, fileName = attachment.FileName });
}
catch (Exception)
{
return Json(string.Empty);
}
}
附件删除
/// <summary>
/// 附件删除
/// </summary>
/// <param name="file"></param>
/// <returns></returns>
[HttpPost]
public ActionResult DelAttachment(string file)
{
try
{
string attachFilePath = WebConfig.Attachment;
string filePath = Path.Combine(attachFilePath, file);
if (System.IO.File.Exists(filePath))
{
System.IO.File.Delete(filePath);
return Json(new { status = "success" });
}
return Json(new { status = "false", message = "附件删除失败!" });
}
catch (Exception ex)
{
return Json(new { status = "false", message = "附件删除失败!" });
}
}
