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.

Downloading CSV contents via Ajax and PHP

I am trying to download CSV contents via PHP script hosted on the server.
This is the jquery code that executes and creates a table:
$(document).ready(function() {
$("#btnSubmit").click(function(){
$.ajax({
type: 'GET',
url: 'http://mydomaincom/wp-content/uploads/get-csv.php',
data: null,
success: function(text) {
var fields = text.split(/\n/);
fields.pop(fields.length-1);
var headers = fields[0].split(','),
html = '<table>';
html += '<tr>';
for(var i = 0; i < headers.length; i += 1) {
html += '<th scope="col">' + headers[i] + '</th>';
}
html += '</tr>';
var data = fields.slice(1, fields.length);
for(var j = 0; j < data.length; j += 1) {
var dataFields = data[j].split(',');
html += '<tr>';
html += '<td>' + dataFields[0] + '</td>';
html += '<td>' + dataFields[1] + '</td>';
html += '<td>' + dataFields[2] + '</td>';
html += '</tr>';
}
html += '</table>';
$(html).appendTo('body');
}
});
});
});
Contents of get-csv.php file:
<?php
header('Content-Type: text/plain');
$csv = file_get_contents('http://mydomaincom/wp-content/uploads/csv-samples.csv');
echo $csv;
?>
Here is the code for button:
<!-- Begin Button -->
<div class="demo">
<input id = "btnSubmit" type="submit" value="Get It"/>
</div>
<!-- End Button -->
From browser:
I can access http://mydomaincom/wp-content/uploads/get-csv.php - no issues
I can access http://mysitecom/wp-content/uploads/csv-samples.csv - no issues
When I click on button nothing happens.
Thanks

Below I tried to put together a working snippet where you can possibly see how it works when it works ...
$(document).ready(function () {
$("#btnSubmit").click(function () {
$.ajax({
type: 'GET',
// url: 'http://mydomaincom/wp-content/uploads/get-csv.php',
// url: 'https://jsonplaceholder.typicode.com/users', // --> JSON
url: "https://data.cdc.gov/api/views/45um-c62r/rows.csv",
data: null,
success: function (text) {
var fields = text.split(/\n/);
fields.pop(fields.length - 1);
var headers = fields[0].split(','), html = '<table>';
html += '<tr>';
for (var i = 0; i < (headers.length,3); i += 1) {
html += '<th scope="col">' + headers[i] + '</th>';
}
html += '</tr>';
var data = fields.slice(1, fields.length);
for (var j = 0; j < data.length; j += 1) {
var dataFields = data[j].split(',');
html += '<tr>';
html += '<td>' + dataFields[0] + '</td>';
html += '<td>' + dataFields[1] + '</td>';
html += '<td>' + dataFields[2] + '</td>';
html += '</tr>';
}
html += '</table>';
$(html).appendTo('body');
}
});
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="btnSubmit">get data</button>
After looking around a bit further I did actually find some publicly available CSV data ("Rates of TBI-related Emergency Department Visits, Hospitalizations, and Deaths - United States, 2001 – 2010" from the U.S. Department of Health & Human Services) and I am now using that to demonstrate the AJAX process.
So, your code basically works. It could be simplified of course but that is not the point. I guess that the problems you encounter with your site are probably CORS-related.

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.

Ajax Data Display fetched from Database

I have a data coming from the database. And Displaying when the ajax function is called. I am able to display it. But, One of the variable is an array data and saved it using implode function. Data is like (a,b,c,d).
Data is displaying in the below format
data1 Data2 Data3 (a,b,c,d) Data5 and so on.
I want to explode the array data and print one below the another.
I should display it like
data1 data2 data3 a data5
b
c
d
Here is the code which i am written to get the data.
<script type="text/javascript">
$('#genreport').on('click',function(){
var Representativeid = document.getElementById("Representativeid").value;
var dateFrom = document.getElementById("dateFrom").value;
var dateTo = document.getElementById("dateTo").value;
var url = '{{URL::to('/admin/GenReport')}}';
$.ajax({
type : 'get',
url : url,
data : {Representativeid:Representativeid,dateFrom:dateFrom,dateTo:dateTo},
success:function(data){
console.log(data);
var $tabledata = $('#tbody');
$tabledata.empty();
for (element in data)
{
var row = '<tr>' +
'<td>' + data[element].date + '</td>'+
'<td>' + data[element].doctor_name + '</td>'+
'<td>' #foreach(explode(',', data[element].products ) as $product)
{{$product}}
#endforeach '</td>' +
'<td>' + data[element].quantity + '</td>'+
'<td>' + data[element].locations +'</td>'+
'<td>' + data[element].area + '</td>'+
'</tr>';
$('#tbody').append(row);
}
},
error:function(data)
{
alert('fail');
alert(data);
}
});
});
</script>
I am failing in the for-each logic. Please help me to display as i expected.

You cannot use a php function/code(server-side) in your javascript/jQuery code(client-side), as the php code will be parsed before the page is loaded. Instead you need to use javascript code.
First, you need to split the value into an array
var productsArray = data[element].products.split(',');
then you would need to get the array count (.length) to use a rowspan, so it doesn't break your table stucture
var rowSpan = productsArray.length;
....
'<td rowspan="'+rowSpan+'">' + data[element].date + '</td>'+
....
finally, you need to loop in javascript, not php, through the array. (note, because the i<0 <td>s go on subsequent rows, you need to add them after)
var rowAfter = "";
for (var i = 0; i < rowSpan; i++) {
if(i == 0) {
row += '<td>' + productsArray[i] + '</td>';
} else {
rowAfter += '<tr><td>' + productsArray[i] + '</td></tr>';
}
}
so it would look something like this -
for (element in data)
{
// get products into an array
var productsArray = data[element].products.split(',');
// get products array count
var rowSpan = productsArray.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>';
} else {
rowAfter += '<tr><td>' + productsArray[i] + '</td></tr>';
}
}
row +=
'<td rowspan="'+rowSpan+'">' + data[element].quantity + '</td>'+
'<td rowspan="'+rowSpan+'">' + data[element].locations +'</td>'+
'<td rowspan="'+rowSpan+'">' + data[element].area + '</td>'+
'</tr>';
// append both row and the <td>s in rowAfter
$('#tbody').append(row+rowAfter);
}

just add <tr><td> inside foreach.
Edit:
Also, take a look at this link. table inside a td

how to assign multiple values to a button when loading table using javascript and json

In the below code i have used a json array(pedingPLT) to load data to below html table. here each an every table data has got a single value. in a particular table data i have included an button.so is there any possibility to assign multiple values to the button (*********), i mean by using an array. kindly help me
function TSC_document_status_list_table_for_tsc_portal() {
var tableData;
$.post("model/tscAdminView.php", {action: 'TSC_document_status_list_table_for_tsc_portal'}, function (e) {
if (e === undefined || e.length === 0 || e === null) {
tableData = '<tr class="error"><td colspan="4"> No Data Found in database </td></tr>';
$('#TSC_document_status_list_table_for_tsc_portal tbody').html('').append(tableData);
} else {
$.each(e, function (index, pedingPLT) {
index++;
tableData += '<tr>';
tableData += '<td>' + index + '</td>';
tableData += '<td>' + pedingPLT.document_id + '</td>';
tableData += '<td>' + pedingPLT.tsc_accepted_Or_Created_date +'</td>';
tableData += '<td>' + pedingPLT.total_allocated_days + ' days' + '</td>';
tableData += '<td>' + pedingPLT.Expired_date + '</td>';
tableData += '<td> <button class="btn btn-sm btn-alt m-r-5 delete_selected_employee" value="' + ******** + '"><i class="fa fa-trash-o fa-lg"></i> </button>' + pedingPLT.total_quantity +'</td>';
tableData += '<td>' + pedingPLT.Completed_phone_list + '</td>';
tableData += '<td>' + pedingPLT.peding_phone_list + '</td>';
tableData += '</tr>';
});
//Load Json Data to Table
$('#TSC_document_status_list_table_for_tsc_portal tbody').html('').append(tableData);
}
}, "json");
}

The value attribute of button is of type "text" (source), so it's not possible to add multiple values to it.
That said, you are free to stringify a JSON-string in it as value, and parse it when you need it:
JSON.stringify()
(method documentation: JSON.stringify)

You can use data-value attribute in the button and put the json string in the data-value attribute.
function TSC_document_status_list_table_for_tsc_portal() {
var tableData;
$.post("model/tscAdminView.php", {action: 'TSC_document_status_list_table_for_tsc_portal'}, function (e) {
if (e === undefined || e.length === 0 || e === null) {
tableData = '<tr class="error"><td colspan="4"> No Data Found in database </td></tr>';
$('#TSC_document_status_list_table_for_tsc_portal tbody').html('').append(tableData);
} else {
$.each(e, function (index, pedingPLT) {
var button_data_value = '{"document_id" : pedingPLT.document_id , "total_days" : pedingPLT.total_allocated_days }';
index++;
tableData += '<tr>';
tableData += '<td>' + index + '</td>';
tableData += '<td>' + pedingPLT.document_id + '</td>';
tableData += '<td>' + pedingPLT.tsc_accepted_Or_Created_date +'</td>';
tableData += '<td>' + pedingPLT.total_allocated_days + ' days' + '</td>';
tableData += '<td>' + pedingPLT.Expired_date + '</td>';
tableData += '<td> <button class="btn btn-sm btn-alt m-r-5 delete_selected_employee" data-value= "'+JSON.Stringify(button_data_value)+'"><i class="fa fa-trash-o fa-lg"></i> </button>' + pedingPLT.total_quantity +'</td>';
tableData += '<td>' + pedingPLT.Completed_phone_list + '</td>';
tableData += '<td>' + pedingPLT.peding_phone_list + '</td>';
tableData += '</tr>';
});
//Load Json Data to Table
$('#TSC_document_status_list_table_for_tsc_portal tbody').html('').append(tableData);
}
}, "json");
}
