ajax回调函数中不能触发input[type='file']事件的解决方法

$.ajax({
url: "",
type: "get",
async: false,
success: function (data) {
if (data.isSuccess) {//存在未生效的数据
//提示是否删除，OK,删除，Cancel，
WindowConfirmDialog(DeleteAndActiveAllData, "There is data that does not take effect if the draft data will continue to be deleted,whether to continue?", "Confirm", "Continue", "Cancel");
} else {
e.preventDefault();
$("#importSupplierExcel").trigger('click');
}
}
});
