<div class="clearfix"></div>
</form>//提交表单
$("#f1").ajaxSubmit({
url: "/ImportAndCheck/ImportCompanyOperation/",
type: "post",
enctype: "multipart/form-data",
dataType: "html",
beforeSubmit: function () {
$(obj).val("保存中...").attr("disabled", true);
},
success: function (response) {
try {
data = JSON.parse(response);
if (data.code > 0) {
layer.msg(data.msg, { time: 1000 });
setTimeout(function () {
window.location.href = "/ImportAndCheck/ImportCompany?status=0";
}, 1000);
} else {
layer.msg(data.msg, { time: 1000 });
$(obj).val("保存").attr("disabled", false);
}
} catch (err) {
layer.msg("导入失败！", { time: 1000 });
$(obj).val("保存").attr("disabled", false);
}
},
error: function (XmlHttpRequest, textStatus, errorThrown) {
layer.msg("导入失败", { time: 1000 });
$(obj).val("保存").attr("disabled", false);
}
});
//服务端
HttpFileCollection files = System.Web.HttpContext.Current.Request.Files;
ReturnJsonCode jsonCode = new ReturnJsonCode();
if (files == null || files.Count == 0)
{
jsonCode.msg = "请选择上传的导入文件";
return jsonCode;
}
//验证文件类型
if (files != null && files.Count > 0)
{
HttpPostedFile file = null;
file = files[0];
//扩展名检查
string picext = System.IO.Path.GetExtension(file.FileName).ToLower();
if (picext != ".xls")
{
jsonCode.msg = "上传文件仅支持xls文档格式";
return jsonCode;
} DataTable db = ExcelToDataTable(file, file.FileName, 0);
