Попробуйте этот код
document.getElementById("upload").addEventListener("change", upload, false);
var out = "";
function upload(e) {
document.getElementById('csvForm').innerHTML = "";
var data = null;
var file = e.target.files[0];
var reader = new FileReader();
reader.readAsText(file);
reader.onload = function(event) {
var csvData = event.target.result;
var parsedCSV = d3.csv.parseRows(csvData);
parsedCSV.forEach(function(d, i) {
if (i == 0) return true; // skip the header
if (d.constructor === Array) {
createForm(d);
}
});
}
}
function createForm(csv) {
out += '<input value="' + csv[0] + '" name="date" type="hidden">';
out += '<input value="' + csv[1] + '" name="name" type="hidden">';
out += '<input value="' + csv[2] + '" name="in-time" type="hidden">';
out += '<input value="' + csv[3] + '" name="out-time" type="hidden">';
document.getElementById('csvForm').innerHTML = out;
document.getElementById('csvForm').setAttribute("formmethod", "post");
document.getElementById('csvForm').setAttribute("formaction", "testBrain.jsp");
out += '<br>';

Я использовал этот вопрос и изменил некоторые вещи, чтобы он работал . Вы можете просмотреть содержимое перед его отправкой, удалив "type = hidden" в createForm JS.
