table length in ajax table

var serial_no = 1;
if (response.length > 0) {
for (var count = 0; count < response.length; count++)
{
html += '<tr>';
html += '<td>' + response[count].id + '</td>';
html += '<td>€' + response[count].inkoopprijs + '</td>';
html += '<td>€' + response[count].verkoopprijs + '</td>';
html += '<td>' + response[count].producten + '</td>';
html += '<td><a href="../prijswijzigen.php?edit=' + response[count].id + '" class="edit_btn">Edit</td>';
html += '<td><a href="C_R_U_D.php?del=' + response[count].id + '" class="del_btn">Delete</td>';
html += '</tr>';
serial_no++;
}
} else {
html += '<tr><td colspan="3" class="text-center">No Data Found</td></tr>';
}
document.getElementById('post_data').innerHTML = html;
document.getElementById('total_data').innerHTML = response.length;
I have this for code for a data table, I made this to support a search function, but I can figure out how to set a table length. I want to set it to ten.

Dynamic Row addition to the Table

I want to add Array elements to the table.
Array elements are dynamic coming from the database. And i am creating the Row for adding the one row from the generated data and appending rowAfter to add the other array elements
Here is the code i have written -
var rowSpan = 0;
var rowSpan1 = 0;
for (element in data)
{
// get products into an array
var productsArray = data[element].products.split(',');
var QuantityArray = data[element].quantity.split(',');
var ChemistArray = data[element].Retailername.split(',');
var PobArray = data[element].Pob.split(',');
rowSpan = productsArray.length;
rowSpan1 = ChemistArray.length;
var row = '<tr>' +
'<td rowspan="'+rowSpan+'">' + data[element].date + '</td>'+
'<td rowspan="'+rowSpan+'">' + data[element].doctor_name + '</td>';
// loop through products array
var rowAfter = "";
for (var i = 0; i < rowSpan; i++) {
if(i == 0) {
row += '<td>' + productsArray[i] + '</td>';
row += '<td>' + QuantityArray[i] + '</td>';
} else {
rowAfter += '<tr><td>' + productsArray[i] + '</td><td>' + QuantityArray[i] + '</td>';
}
}
for (var k = 0; k < rowSpan1; k++) {
if(k == 0) {
row += '<td>' + ChemistArray[k] + '</td>';
row += '<td>' + PobArray[k] + '</td>';
} else {
rowAfter += '<td>' + ChemistArray[k] + '</td><td>' + PobArray[k] + '</td> </tr>';
}
}
row +=
'<td rowspan="'+rowSpan1+'">' + data[element].locations +'</td>'+
'<td rowspan="'+rowSpan1+'">' + data[element].area + '</td>'+
'</tr>';
$('#tbody').append(row+rowAfter);
So as per the code I can finely display ProductArray and Quantity Array
And But i am not able to display the Chemist array after one another.
In the above Image i want to display data( Kapila and Kripa below the Chemist column) Some where making issue with tr and td.
Any help would really appreciated.
Data is a JSON Response -
In my case, ChemistArray(Retailername in response) contains 4 names and POBArray 4 values.

You need to add an empty <td></td> as a "placeholder".
for (element in data) {
var productsArray = data[element].products.split(',');
var quantityArray = data[element].quantity.split(',');
var chemistArray = data[element].Retailername.split(',');
var pobArray = data[element].Pob.split(',');
// find the largest row number
var maxRows = Math.max(productsArray.length, quantityArray.length, chemistArray.length, pobArray.length);
var content = '';
var date = '<td rowspan="' + maxRows + '">' + data[element].date + '</td>';
var doctorName = '<td rowspan="' + maxRows + '">' + data[element].doctor_name + '</td>';
var locations = '<td rowspan="' + maxRows + '">' + data[element].locations + '</td>';
var area = '<td rowspan="' + maxRows + '">' + data[element].area + '</td>';
content += '<tr>' + date + doctorName;
for (var row = 0; row < maxRows; row++) {
// only add '<tr>' if row !== 0
// It's because for the first row, we already have an open <tr> tag
// from the line "content += '<tr>' + date + doctorName;"
if (row !== 0) {
content += '<tr>';
}
// the ternary operator is used to check whether there is items in the array
// if yes, insert the value between the <td></td> tag
// if not, just add an empty <td></td> to the content as a placeholder
content += '<td>' + (productsArray[row] ? productsArray[row] : '') + '</td>';
content += '<td>' + (quantityArray[row] ? quantityArray[row] : '') + '</td>';
content += '<td>' + (chemistArray[row] ? chemistArray[row] : '') + '</td>';
content += '<td>' + (pobArray[row] ? pobArray[row] : '') + '</td>';
// only add "locations + area + '</tr>'" if it is the first row
// because locations and area will span the whole column
if (row === 0) {
content += locations + area + '</tr>';
} else {
content += '</tr>';
}
}
$('#tbody').append(content);
}
content += '<td>' + (productsArray[row] ? productsArray[row] : '') + '</td>'; is just a short-hand for
content += '<td>';
if (productsArray[row]) {
content += productsArray[row];
} else {
content += '';
}
content += '</td>';
If there is item in the productsArray[row], let's say productsArray[0], which is 'Sinarest', then productsArray[row] would be truthy. Else, if there is no more products in the array, such as productsArray[3] will gives us undefined, which is a falsy value and the corresponding conditional will be ran.

How to recreate a table dynamically in javascript

I am creating a table dynamically in a return statement from ajax. But I see only one row of the table, although debugger shows data.length as 4. How do I correct the recreating of table?
// using ajax return to recreate a table
// ...
if (data.length > 0) {
for (var i = 0; i < data.length; i++) {
var $mytablerow = $(
'<table>' +
'<tbody>' +
'<tr>' +
'<td id="td' + data[i].Value + '" >' +
data[i].Text +
'</td>' +
'</tr>' +
'</tbody>' +
'</table>'
);
}
}
var $mylst = $("#Userslist");
$mylst.html($mytablerow);
// ....

using ajax return to recreate a table
...
if (data.length > 0)
{
var $mytablerow = '<table><tbody>';
for (var i = 0; i < data.length; i++)
{
$mytablerow += $(
'<tr>' +
'<td id="td' + data[i].Value + '" >' + data[i].Text + '</td>' +
'</tr>');
}
$mytablerow += '</tbody></table>';
}
var $mylst = $("#Userslist");
$mylst.html($mytablerow);
....

I think you should use a variable outside the loop. For example:
if(data.length > 0) {
var $myTable = '<table><tbody>';
for (var i = 0; i < data.length; i++) {
$myTable += '<tr><td id="td' + data[i].Value + '" >' + data[i].Text + '</td></tr>';
}
$myTable += '</tbody></table>';
}
var $mylst = $("#Userslist");
$mylst.html($myTable);

You have problem in your script. To fix this problem replace by this script:
if (data.length > 0)
{
var $mytablerows = '<table>' + '<tbody>';
for (var i = 0; i < data.length; i++) {
$mytablerows += '<tr>' +
'<td id="td' + data[i].Value + '" >' + data[i].Text + '</td>' +
'</tr>';
}
$mytablerows += '</tbody>' + '</table>';
var $mylst = $("#Userslist");
$mylst.html($mytablerows);
}

That looks like you are creating a single row table each iteration and then only adding the last table you create. You need to create the table stuff once and then iterate to create the rows.

Fill table in javascript with data from db

I have an html <table> that I need to fill with data from a database query. The query returns 10 rows and then sends the data to the method fill(data) to fill the table:
function getTopQ() {
alert("Get top Qs");
callServer('fill', 'checkConnection', false, 'SelectTopQues.php');
}
function fill(data) {
alert("ready to fill now");
$('#table').html('');
var search = '#table';
for (var i = 0; i < data.length; i++) {
$('#table').listview("refresh");
var Questions = data[i];
var str = '<td " ID="' + Questions[0] +
'" Question="' + Questions[1] +
'" UserID="' + Questions[2] +
'"CategoryId"' + '" SubCategoryId"' + '" DatePosted"' + '"';
str += '">'; //end li
str += '<a href="" data-transition="fade">';
str += Questions[1];
str += '</a>';
//str += '<span class="hiddenData">' + item[13] + '</span>';
str += '</td>';
$('#table').append(str);
$('#table').listview("refresh");
}
console.log(data);
console.log($('#table'));
$('#table').listview("refresh");
}

Javascript inserting data into HTML table

This is a rather simple question, I am having problems inserting data from Javascript into an HTML table.
Here is an excerpt of my JavaScript:
UPDATED - I got rid of the two loops and simplified it into one, however there is still a problem..
for (index = 0; index < enteredStrings.length; index++) {
output.innerHTML += "<td>" + enteredStrings[index] + "</td>"
+ "<td>" + enteredStringsTwo[index] + "</td>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}
And here is an except of my HTML page:
<table id="nameTable">
<tr>
<th>First</th><th>Last</th>
</tr>
Updated Picture:

Try this (edited):
var tableContent = '<tr>';
for (index = 0; index < enteredStrings.length; index++) {
tableContent += "<td>" + enteredStrings[index] + "</td>";
nameCounter++; // I don't know if this should be there,
// logically the counter should be incremented here as well?
total.innerHTML = "Total: " + nameCounter;
}
tableContent += '</tr><tr>';
for (index = 0; index < enteredStringsTwo.length; index++) {
tableContent += "<td>" + enteredStringsTwo[index] + "</td>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}
tableContent += '</tr>';
output.innerHTML += tableContent;
Edit2 (for updated question code):
var tableContent = '<tr>';
for (index = 0; index < enteredStrings.length; index++) {
tableContent += "<td>" + enteredStrings[index] + "</td>"
+ "<td>" + enteredStringsTwo[index] + "</td>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}
tableContent += '</tr>';
output.innerHTML += tableContent;
Edit3 (after looking at the code sent in email):
var tableContent = "";
for (index = 0; index < enteredStrings.length; index++) {
tableContent += "<tr><td>" + enteredStrings[index] + "</td>"
+ "<td>" + enteredStringsTwo[index] + "</td></tr>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}
output.innerHTML = tableContent;

instead of closing the td you are opening new ones
try
for (index = 0; index < enteredStrings.length; index++) {
output.innerHTML += "<td>" + enteredStrings[index] + "</td>";
total.innerHTML = "Total: " + nameCounter;
}
for (index = 0; index < enteredStringsTwo.length; index++) {
output.innerHTML += "<td>" + enteredStringsTwo[index] + "</td>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}
UPDATE:
you are appending the html to the table instead of the row.
in this case, the browser created a row for you automatically after the each td is appended.

With slight modifications in your code,
var outputTbl = document.getElementById('nameTable');
var output = document.createElement("tr");
outputTbl.appendChild(output);
for (index = 0; index < enteredStrings.length; index++) {
output.innerHTML += "<td>" + enteredStrings[index] + "</td>";
total.innerHTML = "Total: " + nameCounter;
}
for (index = 0; index < enteredStringsTwo.length; index++) {
output.innerHTML += "<td>" + enteredStringsTwo[index] + "</td>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}

If you need to add inner html code here.
<table id="nameTable" style="width:300px;">
<tr>
<th>First</th><th>Last</th>
</tr>
</table>
You can use Jnerator in this case.
If this is your data:
var data = [
{ first: 'Cole', last: 'Alan'},
{ first: 'Michael', last: 'Scott'}
]
You can add them to you table in next way:
for(var i=0; i<data.length; i++) {
var item = data[i];
var row = $j.tr({ child:[$j.td(item.first), $j.td(item.last)] });
nameTable.appendChild(row.dom());
}
nameTotal.innerHTML = 'Total: ' + data.length;
This is example.
