I trying to add to table search individual with Footer callback to sum currency but I can't write the correct code.

<table id="example">
<thead>

<th>Browser</th>
<th>Platform(s)</th>

<th>price</th>
</tr>
</tfoot>
<tfoot class='custo'>
<tr >
<th colspan=5 style=text-align:right>Total:</th>
<th></th>
</tr>
</tfoot>
<tbody>
<tr>
<td>Trident</td>

JS
/* add input text for table footer */
$('#example tfoot.footer th').each( function () {
var title = $(this).text();
$(this).html( '<input type=\"text\"/>' );
});
/* add the sum of currency */
var table = $('#example').DataTable({
// code for footerCallback goes here but its not working
'footerCallback': function ( row, data, start, end, display ) {
var api = this.api(), data;
var intVal = function ( i ) {
return typeof i === 'string' ?
i.replace(/[\R$,]/g, '')*1 :
typeof i === 'number' ?
i : 0;
};
total = api
.column( 5 )
.data()
.reduce( function (a, b) {
return intVal(a) + intVal(b);
}, 0 );
pageTotal = api
.column( 5, { page: 'current'} )
.data()
.reduce( function (a, b) {
return intVal(a) + intVal(b);
}, 0 );
$( api.column( 5 ).custo() ).html(
'$'+pageTotal +' ( $'+ total +' total)'
);
}
});
/* make the search indvidual when keyup change. */
table.columns().every( function () {
var that = this;
$( 'input', this.footer() ).on( 'keyup change', function () {
if ( that.search() !== this.value ) {
that
.search( this.value )
.draw();
}
});
});
Here the example without the sum currency: http://jsfiddle.net/minamagdy666/e88yrhaj/13/
the example that I want to use for sum currency on that link: enter link description here
Thanks
do this example :
const Table = $('#foo').DataTable({
. . . . . .,
. . . . . .,
drawCallback: function(){
Table.columns(5, {
page: 'current'
}).every(function() {
var sum = this
.data()
.reduce(function(a, b) {
var x = parseFloat(a) || 0;
var y = parseFloat(b) || 0;
return x + y;
}, 0);
console.log(sum);
$(this.footer()).html(sum);
});
}
});
in this case, the column is column number 5

I have a column for number, births and types. If I want to order by Number or Type form ASC or DESC it works perfectly but if I want to order by Birth it doesn't. Is like if I click on "Birth" column, it order by "Number" column I don't know very well what is happening, I have little experience with Javascript, I'm practicing.
let sortDirection = 1;
$(document).ready(() => {
$('th').each(function (columna) {
$(this).click(function () {
let registros = $('table').find('tbody > tr').get();
registros.sort(function (a, b) {
let valor1 = parseInt($(a).children('td').eq(columna).text().toUpperCase(), 16);
let valor2 = parseInt($(b).children('td').eq(columna).text().toUpperCase(), 16);
return valor1 < valor2 ? -1 : valor1 > valor2 ? 1 : 0
});
if (sortDirection === 1) registros.reverse();
sortDirection *= -1; // change direction
$.each(registros, function (indice, elemento) {
$('tbody').append(elemento);
});
});
});

I am having trouble getting multiselect to work properly with the filter function. If I remove multiple from $select, the function filter works properly, but adding multiple selection breaks it. Any suggestions or fix will be greatly appreciated, thank you!
The code I have below currently does not filter because of the multiple attribute, but removing it allows it to only do single selection + filtering.

$table.find('tbody tr').each(function () {
$(this).toggle($(this).find('td').toArray().every(td => {
let $td = $(td), fieldName = $td.attr('data-field-name');
if (fieldName != null) {

filterObj[fieldName].indexOf('all') >= 0 ||
filterObj[fieldName].indexOf($td.text()) >= 0;

return filterObj[fieldName] === null ||
filterObj[fieldName] === '' ||
filterObj[fieldName] === 'all' ||
filterObj[fieldName] === $td.text();

I have an HTML table that has some static data and some from MySQL. It is currently filtering properly, what I need help is adding the "yes" and "no" selections to the selection list. These are just test values, they are being read from MySQL. I am unable to figure out what values to insert here to add values from MySQL to the selection list. Any assistance will be appreciated! Thank you

Not showing yes and no options.
Your filtering logic and odd/even row coloring logic is called BEFORE the data returns from your ajax even though it appears AFTER on the page/code. This is how async methods work.
You need to call the header and coloring logic inside the drawTable() function after, of course, you are done drawing the table... like this:
function drawTable(data) {
for (var i = 0; i < data.length; i++) {
drawRow(data[i]);
}
$('#myTable').initRowClasses('odd', 'even');
$('.dropdown-header').tableFilterHeaders(filterText);
}
Make sure to remove the foloowing 2 lines of code:
$('#myTable').initRowClasses('odd', 'even');
$('.dropdown-header').tableFilterHeaders(filterText);
from your code, wherever elsewhere they appear. Leaving them will not break anything, it will just run multiple times unnecessary.
I have a table in html, I have set for each td an id that I will need to sort the table with a Jquery code.
Sorting works with the FireFox browser, but with Chrome it does not work ... do you know how to help me?
$(function() {
$(".table-user-th").click(function() {
var o = $(this).hasClass('asc') ? 'desc' : 'asc';
$('.table-user-th').removeClass('asc').removeClass('desc');
$(this).addClass(o);
var colIndex = $(this).prevAll().length;
var tbod = $(this).closest("table").find("tbody");
var rows = tbod.find("tr");
rows.sort(function(a, b) {
var A = $(a).find("td").eq(colIndex).attr('id');;
var B = $(b).find("td").eq(colIndex).attr('id');;
if (!isNaN(A)) A = Number(A);
if (!isNaN(B)) B = Number(B);
return o == 'asc' ? A > B : B > A;
});
$.each(rows, function(index, ele) {
tbod.append(ele);
});
});
});

It seems like there is no purpose of using ids here.
Actually the problem was in you sort function. It should return not just true/false but the numeric difference between two values. As usual it is return -1/0/1
So here I wrote comparator func that does just that. And depending on sort type I just multiply it on -1 or 1.
I've also refactored a little bit your code not to use classes or ids. Using jquery you can use data method that stores data on element by key/value.
$(function() {
function cmp(a,b) {return a < b ? 1 : a > b ? -1 : 0}
$(".sortable-table").on('click', 'th', function() {
var th = $(this);
var colIndex = th.data('column');
if(typeof colIndex === 'undefined') {
return;
}
var sortType = th.data('sort') === 'asc' ? 'desc' : 'asc';
th.data('sort', sortType);
var table = $(this).closest("table");
table.find('thead th').removeClass('asc desc');
th.addClass(sortType);
var tbody = table.find("tbody");
var rows = tbody.find("tr");
rows.sort(function(a, b) {
var A = $(a).find("td").eq(colIndex).text();
var B = $(b).find("td").eq(colIndex).text();
return cmp(A,B) * (sortType === 'asc' ? -1 : 1);
});
$.each(rows, function(index, ele) {
tbody.append(ele);
});
});
});

I'm trying to implement a footerCallback in DataTables that computes a conditional sum of each column, based on a cell that's in a different column in the same row. Here's a demo of my setup: https://jsfiddle.net/rantoun/552y9j90/13/
HTML:
<table id="table1">
<thead>
<tr>
<th>Fruit</th>
<th>sumCondition</th>
<th># Eaten</th>
<th># Remaining</th>
</tr>
</thead>
<tfoot>
<tr>
<th></th>
<th align="center">Count</th>
<th align="left"></th>
<th align="left"></th>
</tr>
</tfoot>
<tbody>
<tr>
<td>Apples</td>
<td>Use</td>
<td>3</td>
<td>8</td>
</tr>
<tr>
<td>Oranges</td>
<td>Use</td>
<td>6</td>
<td>5</td>
</tr>
<tr>
<td>Bananas</td>
<td>Ignore</td>
<td>2</td>
<td>9</td>
</tr>
</tbody>
</table>
jQuery:
$("#table1").DataTable({
"paging": false,
"searching": false,
"info": false,
"footerCallback": function ( row, data, start, end, display ) {
var columns = [2, 3];
var api = this.api();
_.each(columns, function(idx) {
var total = api
.column(idx)
.data()
.reduce(function (a, b) {
return parseInt(a) + parseInt(b);
}, 0)
$('tr:eq(0) th:eq('+idx+')', api.table().footer()).html(total);
})
}
});
Specifically, my goal is for the footerCallback to only sum the rows where "Ignore" is NOT in the Condition column. Hopefully this is clear and any help is appreciated.
I solved this by getting the current index of the summing value in the reduce function and then using the index to access the respective value in the condition cell. Below is the new jQuery code:
$('#table1').DataTable({
'paging': false,
'searching': false,
'info': false,
'footerCallback': function (row, data, start, end, display) {
var columns = [2, 3];
//console.log(data);
var api = this.api();
// Get sumCondition and put in array
_.each(columns, function (idx) {
var total = api
.column(idx)
.data()
.reduce(function (a, b) {
// Find index of current value for accessing sumCondition value in same row
var cur_index = api.column(idx).data().indexOf(b);
if (api.column(1).data()[cur_index] != 'Ignore') {
return parseInt(a) + parseInt(b);
} else {
return parseInt(a);
}
}, 0);
$('tr:eq(0) th:eq(' + idx + ')', api.table().footer()).html(total);
});
},
});
