Hello I am new to website development (started a couple of days ago).
I have some programming experience using Python and C#.
I have been trying to generate an HTML table using JS and apply it a Bootstrap css style.
I can't seem to get it to work.
What I get:
What I want:
I hope to get something that styles like this (simplified from: w3schools)
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Example</title>

<div class="container">
<h2>Basic Table</h2>
<p>The .table class adds basic styling (light padding and only horizontal dividers) to a table:</p>
<table class="table">
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Email</th>
</tr>
<tr>
<td>John</td>
<td>Doe</td>
<td>john#example.com</td>
</tr>
</table>
</div>
</body>
</html>
My html page looks like this:
<!DOCTYPE html>
<html>
<head>
<title>CSVParser</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<form onsubmit="return processFile();" action="#" name="myForm" id="aForm" method="POST">

<input type="submit" name="submitMe" value="Process File">
</form>
<table id="myTable" class="table"></table>
</div>
</body>
</html>
and the JS script is:
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 count = 0; count < lines.length; count++) {
var row = document.createElement("tr");
var rowContent = lines[count].split(",");
for (var i = 0; i < rowContent.length; i++) {
if (count == 0) {
var cellElement = document.createElement("th");
} else {
var cellElement = document.createElement("td");
}
var cellContent = document.createTextNode(rowContent[i]);
cellElement.appendChild(cellContent);
row.appendChild(cellElement);
}
myTable.appendChild(row);
}
}
myReader.readAsText(theFile);
}
return false;
}
The csv data file I load looks like this:

Beta,0.191220409,0.279946678,57.55254144
This is the generated HTML table from the JS:
<table id="myTable" class="table">

<th>TestB</th>
<th>TestC</th>
<th>TestD</th>
</tr>
<tr>
<td>Alpha</td>
<td>0.551608445</td>

</tr>
<tr>
<td>Beta</td>
<td>0.191220409</td>
<td>0.279946678</td>
<td>57.55254144</td>
</tr>
<tr>
<td></td>
</tr>
</table>
You are missing a <tbody> element around all the <tr> Elements. thats it. if you insert this additionally you are fine with your layout.
I've changed your code quite a bit but here is a working example:
<!DOCTYPE html>
<html>
<head>
<title>CSVParser</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<form action="#" name="myForm" id="aForm" method="POST">
<input type="file" id="myFile" name="myFile"><br>
<input type="button" name="submitMe" value="Process File" onclick="processFile();">
</form>
<table id="myTable" class="table"></table>
</div>
</body>
<script type="text/javascript">
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");
var tbody = document.createElement("tbody");
for (var count = 0; count < lines.length; count++) {
var row = document.createElement("tr");
var rowContent = lines[count].split(",");
for (var i = 0; i < rowContent.length; i++) {
if (count == 0) {
var cellElement = document.createElement("th");
} else {
var cellElement = document.createElement("td");
}
var cellContent = document.createTextNode(rowContent[i]);
cellElement.appendChild(cellContent);
row.appendChild(cellElement);
}
tbody.appendChild(row);
}
table.appendChild(tbody);
}
myReader.readAsText(theFile);
}
return false;
}
</script>
</html>
Working example without having to upload a file

</script>
</html>
ALSO! You are using myTable.appendChild(row); in your code although you've never initialized any myTable variable.
Load your js script just before the </body> end tag.
Now you are loading the JavaScript before the browser has read all your tags and by then it can't find the elements you are querying in your script.
<body>
<div class="container">
<form onsubmit="return processFile();" action="#" name="myForm" id="aForm" method="POST">
<input type="file" id="myFile" name="myFile"><br>
<input type="submit" name="submitMe" value="Process File">
</form>
<table id="myTable" class="table"></table>
</div>
<!-- Here's the difference -->
<script type="text/javascript" src="../scripts/csvToHtml.js"></script>
</body>
I am trying to use jQuery with firebase on the web and am building a quick table of users and tickets. The users and tickets are displaying properly, however they are iterated over twice, in that the table contains the same users and tickets twice. I am not sure what is happening.`
var users = ["Nick","Peter"];
var rows = "";
var number = 0;
//Sync all changes
dbRefAllUsers.on('value', function(snap) {
console.log("#Run",number+1);
jQuery.each(users, function(index,name){
console.log(name);
rows += "<tr><td>" + name + "</td><td>" + snap.child(name).child("tickets").val() + "</td></tr>";
console.log(rows);
});
$(rows).appendTo("#ticketTable tbody");
return head.innerText = JSON.stringify(snap.val(), null, 3);
});`

I get the information from the user from a form, and have a button that is clicked and fires off to save the values into variables.

Local Storage is your best bet.
// Save data to the current local store
localStorage.setItem("username", "John");

alert( "username = " + localStorage.getItem("username"));

I have a jsp which onload calls a js in which a table is created dynamically.
The situation is that I have never worked on jquery earlier, all I know is javascript.
I made two scenarios:
case one : when I create static table on the jsp page itself it works flawlessly.
case two : when I try to load the same table which is created by dynamic javascript it fails.
Case I Working code
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
<script src="../js/jquery.js"></script>
<script type="text/javascript" src="../js/createDynamicTable.js"></script>
<script type="text/javascript" src="../js/jquery.dataTables.js"></script>
<script>
$(document).ready(function() {
$('#testTable').dataTable();
});
</script>
</head>
<body>
<div id="tableDataDiv">
<table id="testTable">
<thead>
<th>h1</th>
<th>h2</th>
<th>h3</th>
</thead>
<tbody>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>4</td>
<td>5</td>
<td>6</td>
</tr>
<tr>
<td>7</td>
<td>8</td>
<td>9</td>
</tr>
</tbody>
</table>
</div>
</body>
</html>
Case II Not Working code
jsp code
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
<script src="../js/jquery.js"></script>
<script type="text/javascript" src="../js/createDynamicTable.js"></script>
<script type="text/javascript" src="../js/jquery.dataTables.js"></script>
<script>
$(document).ready(function() {
$('#testTable').dataTable();
});
</script>
</head>
<body onload="getTableData();">
<div id="tableDataDiv">
</div>
</body>
</html>
js code
function getTableData(){
var tableDataDivObj = document.getElementById("tableDataDiv");
var tableObj = document.createElement("table");
tableObj.id = 'testTable';
// header
var theadObj = document.createElement("thead");
var thObj = document.createElement("th");
thObj.innerHTML = 'h1';
theadObj.appendChild(thObj);
thObj = document.createElement("th");
thObj.innerHTML = 'h2';
theadObj.appendChild(thObj);
thObj = document.createElement("th");
thObj.innerHTML = 'h3';
theadObj.appendChild(thObj);
tableObj.appendChild(theadObj);
// body
var tbodyObj;
var trObj;
var tdObj;
tbodyObj = document.createElement("tbody");
var count = 1;
for(i = 0; i < 3; i++){
trObj = document.createElement("tr");
for(j = 0; j < 3; j++){
tdObj = document.createElement("td");
tdObj.innerHTML = count;
trObj.appendChild(tdObj);
count++;
}
tbodyObj.appendChild(trObj);
}
tableObj.appendChild(tbodyObj);
tableDataDivObj.appendChild(tableObj);
}
Once the table is created dynamically, we append it to the div on the jsp page.
Kindly suggest any modification, suggestions so that I can get this code work.
this is just an example I have created of my real application .
which involves complete mvc, where table data is retrived from the service methods and dao files. I am able to get the data into the table(I made sure after getting an alert on jsp page). I am not able to use datatable on the id of the table.
Thanks in advance!
When your dataTables initialization is run, the table doesn't exist yes. You can fix by moving the $('#testTable').dataTable(); after the table has been initialized.
$(tableObj).dataTable();
at the end of the getTableData function (which should be defined in your $(document).ready callback.
Yon can add datatable to your dynamically created table in javascript.Code is as follows:
<html>
<head>

function createTable(){
var myTableDiv = document.getElementById("box");
var table = document.createElement('TABLE');
table.id='tableId'
table.border='1';
var header = table.createTHead();
var row = header.insertRow(0);
var cell = row.insertCell(0);
var cell1 = row.insertCell(1);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(1);
cell.innerHTML = "<b>Name</b>";
cell1.innerHTML = "<b>Age</b>";
cell2.innerHTML = "<b>Email</b>";
cell3.innerHTML = "<b>address</b>";
var tableBody = document.createElement('TBODY');
table.appendChild(tableBody);
for (var i=0; i<3; i++){
var tr = document.createElement('TR');
tableBody.appendChild(tr);
for (var j=0; j<4; j++){
var td = document.createElement('TD');
td.width='75';
td.appendChild(document.createTextNode("Cell " + i + "," + j));
tr.appendChild(td);
}
}
myTableDiv.appendChild(table);
$("#tableId").dataTable();
}
</head>
<body>
<input type="button" onclick="createTable();" value="CreateTable" /></br>
<div id="box">
</div>
</body>
</html>
Please call jquery method once your table get created by dynamic javascript.
You can find example here how to create dynamically:
http://datatables.net/release-datatables/examples/data_sources/js_array.html
I have a table with 20 lines, and I wanted their rows to go up (skipping the first row line) after 1 minute the page has loaded.
Ex:
Initial
row1
row2
row3
First steo
row2
row3
row1
second state
row3
row1
row2
Final step
row1
row2
row3
I was doing something like this, but I don't know how to replace the content of the rows.
And if possible do it slowly (gradual would be great but now essencial)
function roll()
{
var oRows = document.getElementById('ultNot').getElementsByTagName('tr');
var iRowCount = oRows.length;
//repeat this iRowCount-1?
for (i=iRowCount; i=2;;i--){
var tempRow= oRows[i];
var origRow;
if (i=rowCount) {
origRow=oRows[1];
} else {
origRow=cRows[i-1];
}
var tempContent=origRow;
//replace the contents of the rows
}
}
thanks a lot for any help
Thanks Razvan, that did the trick. The whole code to do what I wanted (which is to roll the complete group of rows 1 time after 40 seconds):

There probably is a better way but this is all I could come up with until now :)
