Reorder CSV rows

I have this code which basically reads a CSV and should output a table where the CSV row content should be reordered!
Example :
fish;4;1;33
fish should be at 1 row column 4.
dog;5;2;66
dog should be at 2nd row column 5
The problem is that it doesn't print anything, neither at the console! Can you please show me where I am wrong? What modifications should I do?
My code:
function processFile() {
var fileSize = 0;
var theFile = document.getElementById("myFile").files[0];
if (theFile) {
var table = document.getElementById("myTable");
var headerLine = "";
var myReader = new FileReader();
myReader.onload = function(e) {
var content = myReader.result;
var lines = content.split("\r");
for (var i = 0; i <lines.length; i++)
{
document.write("<th>");
document.write(" ");
document.write("</th>");
}
for (var i = 0; i <lines.length; i++)
{
document.write("<tr>");
for (var j = 0; j <lines.length; j++)
{
document.write("<td>");
document.write(" ");
document.write("</td>");
}
document.write("</tr>");
}
function insertData(id, content) {
var dataRows = content.split("\r");
if (table) {
dataRows.forEach(function(s) {
var x = s.split(';');
table.rows[x[2]].cells[x[1]].textContent = x[0];
});
}
}
}
myReader.readAsText(theFile);
}
return false;
} //end

So, i did everything again for you with a big example.
I think you can handle it in your code, or take mine in the example.
Here are the main functions you can safely use in your case :
//for swapping values
function swap(arr, a, b){
var tmp = arr[a];
arr[a] = arr[b];
arr[b] = tmp;
return arr;
}
//for reorder lines a<=>b
function reorderLine(csvArray,a,b){
return swap(csvArray,a,b);
}
//for reorder one col values a<=>b
function reorderColumn(csvLine,a,b){
return swap(csvLine.split(";"),a,b).join(';');
}
// create a table with csv data
function csvArrayToTable(csvArray,selectorId){
var html = ["<table cellpadding='10' border='1'>"];
csvArray.map(function(lines){
html.push("<tr>");
var cols = lines.split(";");
html.push("<th>"+cols[0]+"</th>");
cols.shift();
cols.map(function(val){
html.push("<td>"+val+"</td>");
});
html.push("</tr>");
});
html.push("</table>");
document.getElementById(selectorId).innerHTML = html.join('');
}
And a working example you can use too, upload file is included (click on Run code snippet at the bottom of the post, and full page to test) :
//for swapping values
function swap(arr, a, b){
var tmp = arr[a];
arr[a] = arr[b];
arr[b] = tmp;
return arr;
}
//for reorder lines a<=>b
function reorderLine(csvArray,a,b){
console.log('reorderLine',csvArray,a,b);
return swap(csvArray,a,b);
}
//for reorder one col values a<=>b
function reorderColumn(csvLine,a,b){
console.log('reorderColumn',csvLine,a,b);
return swap(csvLine.split(";"),a,b).join(';');
}
// create a table with csv data
function csvArrayToTable(csvArray,selectorId){
var html = ["<table cellpadding='10' border='1'>"];
csvArray.map(function(lines){
html.push("<tr>");
var cols = lines.split(";");
html.push("<th>"+cols[0]+"</th>");
cols.shift();
cols.map(function(val){
html.push("<td>"+val+"</td>");
});
html.push("</tr>");
});
html.push("</table>");
document.getElementById(selectorId).innerHTML = html.join('');
}

Getting blank screen after running Google web app script

I am working on a check-in app though Google Sheets and want to make a search function that that takes a sport name as input in an HTML form and then returns information about the sport from the sheet in a HTML table. However, when I try to test the web app, nothing happens. How can I fix this?
Here is my code:
Index.html
<!DOCTYPE html>
<html>
<head>
<?!= HtmlService.createHtmlOutputFromFile('Stylesheet').getContent(); ?>
</head>
<body>
<fieldset id="tasks-panel">
<legend>Sports</legend>
<form name="sport-form" id="sport-form">
<label for="sport-name">Search a sport by name:</label>
<input type="text" name="sport-name" id="sport-name" />
<button onclick='addTable()' id='submit-button'>Press this</button>
</form>
<p>List of things:</p>
<div id="toggle" style="display:none"></div>
</fieldset>
<?!= HtmlService.createHtmlOutputFromFile('Javascript').getContent(); ?>
</body>
</html>
Javascript.html
<script>
function addTable() {
var sportInput = $('sport-name').value();
var columnNames = ["Names", "Times"];
var dataArray = google.script.run.getSportData(sportInput);
var myTable = document.createElement('table');
$('#divResults').append(myTable);
var y = document.createElement('tr');
myTable.appendChild(y);
for(var i = 0; i < columnNames.length; i++) {
var th = document.createElement('th'),
columns = document.createTextNode(columnNames[i]);
th.appendChild(columns);
y.appendChild(th);
}
for(var i = 0 ; i < dataArray.length ; i++) {
var row= dataArray[i];
var y2 = document.createElement('tr');
for(var j = 0 ; j < row.length ; j++) {
myTable.appendChild(y2);
var th2 = document.createElement('td');
var date2 = document.createTextNode(row[j]);
th2.appendChild(date2);
y2.appendChild(th2);
}
}
}
</script>
Code.gs
//Setting up global variables
var ss = SpreadsheetApp.openById("-spreadsheetID-");
var sheet = ss.getSheetByName("Sheet1");
var sportsFromSheet = sheet.getRange("D4:D12");
var namesFromSheet = sheet.getRange("B4:B12").getValues();
var timesFromSheet = sheet.getRange("A4:A12").getValues();
var NAMES = [];
var TIMES = [];
var OUTPUT = [];
//doGet function
function doGet() {
return HtmlService.createTemplateFromFile('Index').evaluate()
.setTitle('Check In Data')
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
}
//Gets both names and times of checked-in people
function getSportData(input) {
var sportInput = input;
getNamesInSport(sportInput);
getTimesInSport(sportInput);
OUTPUT = [
[NAMES],
[TIMES]
];
Logger.log(OUTPUT);
return OUTPUT;
}
//Puts the names of every person from an inputted sport into an array.
function getNamesInSport(input) {
var data = sportsFromSheet.getValues();
for (var i = 0; i < data.length; i++) {
if(data[i] == input){
NAMES.push(namesFromSheet[i][0]);
}
}
}
//Puts the times of every person from an inputted sport into an array.
function getTimesInSport(input){
var data = sportsFromSheet.getValues();
for (var i = 0; i < data.length; i ++) {
if(data[i] == input){
TIMES.push(timesFromSheet[i][0]);
}
}
}

JQuery id selectors must be prefixed with # so to grab the value from the the 'sport-name' input you'll need to select it using
var sportInput = $('#sport-name').val();
Additionally, as Robin comments above, if you want to use the JQuery library you'll need to load it, the code you've shown indicates you might not have done this?
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</head>
Although if this were the case you'd probably be seeing a '$ is not defined' error straight away.

how to add checkboxes in cells of first column of HTML table?

I am working on an app development which will read through my mailbox and list all the unread e-mails in a HTML table on my web-app upon click of a button. Below is the code which I have made while researching through google which solves for the purpose.
<!DOCTYPE html>
<html>
<body>
<button onclick="groupFunction()">Click me</button>
<table id="tblContents">
<tr onclick="tableClickTest()">
<th>Sender</th>
<th>Sent_Date</th>
<th>Received_By</th>
<th>Received_Date</th>
<th>Subject</th>
</tr>
</table>
<script>
function RowSelection()
{
var table = document.getElementById("tblContents");
if (table != null) {
for (var i = 0; i < table.rows.length; i++) {
for (var j = 0; j < table.rows[i].cells.length; j++)
table.rows[i].cells[j].onclick = function () {
tableText(this);
};
}
}
}
function tableText(tableCell) {
alert(tableCell.innerHTML);
}
function PopulateTable()
{
var objOutlook = new ActiveXObject("Outlook.Application");
var session = objOutlook.Session;
//alert(session.Folders.Count)
for(var folderCount = 1;folderCount <= session.Folders.Count; folderCount++)
{
var folder = session.Folders.Item(folderCount);
//alert(folder.Name)
if(folder.Name.indexOf("Premanshu.Basak#genpact.com")>=0)
{
for(var subFolCount = 1; subFolCount <= folder.Folders.Count; subFolCount++)
{
var sampleFolder = folder.Folders.Item(subFolCount);
//alert(sampleFolder.Name)
if(sampleFolder.Name.indexOf("test1")>=0)
{
for(var itmCount = 1; itmCount <= sampleFolder.Items.Count; itmCount++)
{
var itm = sampleFolder.Items.Item(itmCount);
if(!itm.UnRead)
continue;
var sentBy = itm.SenderName;
var sentDate = itm.SentOn;
var receivedBy = itm.ReceivedByName;
var receivedDate = itm.ReceivedTime;
var subject = itm.ConversationTopic;
// var contents = itm.Body;
var tbl = document.getElementById("tblContents");
if(tbl)
{
var tr = tbl.insertRow(tbl.rows.length);
// tr.onclick(tableClickTest())
if(tbl.rows.length%2 != 0)
tr.className = "alt";
var tdsentBy = tr.insertCell(0);
var tdsentDate = tr.insertCell(1);
var tdreceivedBy = tr.insertCell(2);
var tdreceivedDate = tr.insertCell(3);
var tdsubject = tr.insertCell(4);
// var tdcontents = tr.insertCell(5);
tdsentBy.innerHTML = sentBy;
tdsentDate.innerHTML = sentDate;
tdreceivedBy.innerHTML = receivedBy;
tdreceivedDate.innerHTML = receivedDate;
tdsubject.innerHTML = subject;
// tdcontents.innerHTML = contents;
}
//itm.UnRead = false;
}
break;
}
}
break;
}
}
return;
}
function groupFunction()
{
PopulateTable()
RowSelection()
}
</script>
</body>
</html>
The thing that I am now looking for and is unable to do is how do I add a checkbox in the first column in each row. Also upon checking this checkbox the entire row should get highlighted so that I can perform specific task on all the selected items.

As far as I have understood your code, your first column's data is being set as:
tdsentBy.innerHTML = sentBy;
So in the same line, you can add textbox as a string as:
var cbox = "<div class='select-box'>
<input type='checkbox' name='selectBox' class='select-row'>
</div?>"
tdsentBy.innerHTML = cbox + sentBy;
In this way, a checkbox will always be available in first column of every row.
Now in RowSelection function, to bind event you can do something like:
var checkBox = table.rows[i].cells[j].querySelector(".select-row");
checkBox.addEventListener("click",function(evt){
});

Refresh error loading local storage data

Sorry for being such a noob. I'm a student and I can't figure out what is wrong with my script. My code is a budget app where you enter values and it stores the info into local storage. It works when you calculate the expected and actual expenses, but when I refresh the page it adds a new row and with "undefined values". Any ideas?
<html>
<body onload="load()">

<input type="text" placeholder="Totals">
<input type="text" id="output-expected">
<input type="text" id="output-actual">
</div>
<button onclick="addRow()">Add New Row</button>
<input type="button" value="Save" onclick="save()" />
<input type="button" value="Add Expected" onclick="addExpectedTotals()" />
<input type="button" value="Add Actual" onclick="addActualTotals()" />
</div><!-- budget-list -->
</body>
</html>
<script>
/* BUDGET APP

How do I delete a record in my javascript to do list?
