先引用 ajaxfileupload.js 没有自己去csdn下
接下来是HTML
<input type=”file” id=”file1″ name=”file” style=”display: none” accept=”image/x-png,image/gif,image/jpeg,image/bmp” multiple=”multiple” />
<button type=”button” class=”btn btn-info” id=”btnFile”><i class=”fa fa-cloud-upload”> 上传</i></button>
其中 accept 可以指定上传格式 multiple=”multiple” 此属性可进行多文件选择
JS部分
$(“#btnFile”).click(function () {
$(“#file1”).click();
})
$(“#file1”).change(function () {
if ($(“#file1”).val().length > 0) {
ajaxFileUpload();
}
else {
swal({ title: ‘请选择上传文件!’, text: ”, type: ‘info’ });
}
});
function ajaxFileUpload() {
$.ajaxFileUpload
(
{
url: ‘/FinancialReimbursement/FinancialReimbursement/Upload’, //用于文件上传的服务器端请求地址
type: ‘post’,
data: { Id: ‘123’, name: ‘add’ }, //此参数非常严谨,写错一个引号都不行
secureuri: false, //是否需要安全协议,一般设置为false
fileElementId: ‘file1’, //文件上传域的ID
dataType: ‘json’, //返回值类型 一般设置为json
success: function (data, status) //服务器成功响应处理函数
{
alert(“上传成功”);
},
error: function (data, status, e)//服务器响应失败处理函数
{
alert(e);
}
}
)
后台部分
public ActionResult Upload()
{
NameValueCollection nvc = System.Web.HttpContext.Current.Request.Form;
string type = nvc.Get(“name”);//获取参数
HttpFileCollection hfc = System.Web.HttpContext.Current.Request.Files;
if (hfc.Count > 0 )
{
#region 执行多个文件上传
for (int i = 0; i < hfc.Count; i++)
{
var FileNameArr = hfc[i].FileName.Split(‘.’);
string FileName = DateTime.Now.ToString(“yyyyMMddhhmmss”) + “_” + FileNameArr[0] + “.” + FileNameArr[1];
imgPath += “/AllFileUp/ForTheAttachment/” + FileName + “,”;
string imgP = “/AllFileUp/ForTheAttachment/” + FileName;
string PhysicalPath = Server.MapPath(imgP);
if (!Directory.Exists(Server.MapPath(“/AllFileUp/ForTheAttachment”)))//存放路径文件夹不存在就自动新建
{
Directory.CreateDirectory(Server.MapPath(“/AllFileUp/ForTheAttachment”));
}
hfc[i].SaveAs(PhysicalPath);
}
#endregion
}
return Json(new { count = hfc.Count});//返回保存文件的个数
}
写的很乱 第一次写 一点格式都没有 哈哈哈
