ajax模拟表单提交，后台使用npoi实现导入操作 方式二
页面代码：
<form id="form1" enctype="multipart/form-data">
<div style="float:right">
<button type="button" class="btn btn-primary" onclick="$('#fileUpload').click()" id="reviewFile">浏览</button>
<button class="btn btn-primary" type="button" style="margin-left:5px;height:30px;" id="dataExport">批量导入</button>
<input type="button" class="btn btn-primary" style="margin-left:5px;height:30px;" id="downLoad" value="下载模板">
</div>
<div style="float:right;margin-top:5px">
<input id="fileUpload" name="fileUpload" type="file" style="display:none" />
<input id="fileText" type="text" class="form-control" disabled />
</div>
<script>
$("#fileUpload").change(function () {
$("#fileText").val($(this).val());
})
</script>
</form>
js代码：
//导入excel数据
$("#dataExport").click(function () {
var formData = new FormData($('form')[0]);
$.ajax({
url: '/BaseInfoPage/GetAllDataFromExcel',
type: 'POST',
xhr: function () {
return $.ajaxSettings.xhr();
},
data: formData,
cache: false,
contentType: false,
processData: false,
success: function (data) {
if (data == "导入成功!") {
layer.msg(data, { icon: 1, time: 5000 }, function () {
location.reload(); //刷新父页面 第二个参数设置msg显示的时间长短
});
} else {
layer.msg(data, { icon: 0, time: 5000 }, function () {
