最近项目中成绩管理的老师布置作业部分,涉及到了office文件的上传和预览。经过几番折腾,终于达到预期效果。
项目是基于MVC+EsayUI实现的,在此分享一下上传文件的代码:
View:
<script src="../../Scripts/MyScript/DatagridOperate.js" type="text/javascript"></script>
<div id="Priview" closed="true" class="easyui-dialog" style="width: 360px; height: auto; padding-top: 30px; padding-bottom: 30px; padding-left: 25px;"
buttons="#dlg-buttons" title="文件预览">
<form id="AddHomeWork" method="post" action="/TeaQueryHomework/AddHomeW">
<div id="upload" style="width: 300px; display: block; padding-bottom: 15px; padding-top: 15px;">
<input type="file" class="easyui-linkbutton" name="fileToUpload" id="fileToUpload"
multiple="multiple" onchange="fileSelected();" />
<a id="" class="easyui-linkbutton" href="#" data-options="plain:true,iconCls:‘icon-undo‘" style="margin-left: 5px;" onclick="uploadFile()">
<span>上传</span>
</a>
</div>
</form>
</div>
Controller上传文件方法:
[HttpPost]
[ValidateInput(false)]
public string UploadFile(HttpPostedFileBase[] fileToUpload)
{
#region 旧版
try
{
string FileUrl = string.Empty;
//TODDO:读取任何地方的路径
foreach (HttpPostedFileBase file in fileToUpload)
{
path = System.IO.Path.Combine(Server.MapPath("~/"), System.IO.Path.GetFileName(file.FileName));
//在path路径下保存文件
file.SaveAs(path );
}
}
catch (Exception e)
{
//
}
}
JS代码:
//选择上传文件
function fileSelected() {
var file = document.getElementById(‘fileToUpload‘).files[0];
var fileName = file.name;
var file_typename = fileName.substring(fileName.lastIndexOf(‘.‘), fileName.length);
if (file_typename == ‘.xls‘ || file_typename == ‘.xlsx‘ || file_typename == ‘.doc‘ || file_typename == ‘.docx‘) {//这里限定上传文件文件类型
if (file) {
$("#uploadFile").show();
var fileSize = 0;
if (file.size > 1024 * 1024)
fileSize = (Math.round(file.size * 100 / (1024 * 1024)) / 100).toString() + ‘MB‘;
else
fileSize = (Math.round(file.size * 100 / 1024) / 100).toString() + ‘KB‘;
document.getElementById(‘fileName‘).innerHTML = ‘文件名: ‘ + file.name;
document.getElementById(‘fileSize‘).innerHTML = ‘大小: ‘ + fileSize;
document.getElementById(‘fileType‘).innerHTML = ‘类型: ‘ + file.type;
}
}
else {
//当上传格式错误后,提示
$("#uploadFile").hide();
document.getElementById(‘fileName‘).innerHTML = "<span style=‘color:Red‘>错误提示:上传文件应该是.xls后缀而不应该是" + file_typename + ",请重新选择文件</span>"
document.getElementById(‘fileSize‘).innerHTML = "";
document.getElementById(‘fileType‘).innerHTML = "";
}
}
//上传文件的方法
function uploadFile() {
var fd = new FormData();
fd.append("fileToUpload", document.getElementById(‘fileToUpload‘).files[0]);
var xhr = new XMLHttpRequest();
xhr.upload.addEventListener("progress", uploadProgress, false); //上传进度
xhr.addEventListener("load", uploadComplete, false); //上传完成
xhr.addEventListener("error", uploadFailed, false); //上传出错
xhr.addEventListener("abort", uploadCanceled, false); //取消上传
xhr.addEventListener("success", uploadSuccess, false);//上传成功
xhr.open("POST", "/TeaQueryHomework/UploadFile"); //Controller里边UploadFile方法
xhr.send(fd);
}
//上传文件
function uploadProgress(evt) {
if (evt.lengthComputable) {
var percentComplete = Math.round(evt.loaded * 100 / evt.total);
$(‘#progressNumber‘).progressbar(‘setValue‘, percentComplete);
}
else {
document.getElementById(‘progressNumber‘).innerHTML = ‘无法计算‘;
}
}
//完成上传文件的操作
function uploadComplete(evt) {
/* 服务器返回数据*/
var message = evt.target.responseText;
}
//上传文件成功
function uploadSuccess(evt) {
/* 服务器返回数据*/
alert("上传成功.");
}
//上传文件失败
function uploadFailed(evt) {
alert("上传出错.");
}
//取消上传文件
function uploadCanceled(evt) {
alert("上传已由用户或浏览器取消删除连接.");
}
文件的上传由以上几行简单的代码就能搞定了,老师布置作业,将作业上传到服务器就完成了。下一篇博客将介绍上传文件的预览功能,未完待续~~~
