限制文件上传格式：
1、图片格式
accept="image/*"
仅限制gif png格式
accept="image/gif,image/png"
2、excel格式
//限制.xls文件
accept="application/vnd.ms-excel"
//限制.xlsx文件
accept="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"同时限制上传.xls、.xlsx文件
accept="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,application/vnd.ms-excel "
或
accept=".xls,.xlsx"
js部分
//批量导入
function BatchImport()
var form = new FormData(), fileInput = document.getElementById("fileInput");
form.append("file", fileInput.files[0]);
if (!attributeid)
layer.msg("请先选择导入部门！");
return;
layer.confirm('您确定要导入该文件吗？',
btn: ['确定', '取消'] //按钮
, function ()
$.ajax(
url: src + "/api/MailList/InsertPhone?attrid=" + attributeid,
type: "POST",
contentType: false,
processData: false,
data: form,
success: function (data)
if (data)
layer.msg("导入成功", icon: 1 );
fileInput.value = "";
setTimeout(() => loadUserlist(); , 1000);
,
error: function (msg)
console.log(msg)
)
, function ()
layer.close(50)
)
js部分限制上传文件类型
if (!['application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/vnd.ms-excel'].includes(fileInput.files[0].type))
layer.msg('只能上传.XLS|.XLSX格式的文件！', icon: 2 );
return;

完整版excel上传导入读写批量数据并将反馈结果写入远程exel中
思路：excel的读写借助于poi框架，在写入远程的时候，是不能直接写入的，本博主将传入的文件再次拉下来写到项目临时文件中，然后，在临时文件中写入，然后，以同样的名称路径覆盖掉远程的就可以了，稍微有点绕了，从远端获取文件，需要通过流来写到项目临时文件中，具体见下方代码，代码中有部分业务删减，该代码是在工作中运行通过的。模板是我们自己制定的，所以只适合已有模板。
