How to create filter for each column of a table with jquery?

Navigation
1

Objective - It can be in jquery or vanilla javascript

I think, create dependent filters, that is. A filter B can only search filtered data by filter A. One example would be, if in column A I write c, column B can only search between d or f. If in such a case b is placed, nothing should happen since this data is not inside the filter A

Current Code

  • When I look for A in column one, and then I put D in column two, the table disappears obviously
  • I'm placing empty, because then I would need to export the filtered with excel (it will export what the table has in the sun) 

    • $(document).ready(function () {
        $('#inputUno').keyup(function () {
            $("#table td.col1:contains('" + $(this).val() + "')").parent().show();
            $("#table td.col1:not(:contains('" + $(this).val() + "'))").parent().empty();
        });
        $('#inputDos').keyup(function () {
            $("#table td.col2:contains('" + $(this).val() + "')").parent().show();
            $("#table td.col2:not(:contains('" + $(this).val() + "'))").parent().empty();
        });
    });
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
    <input type="text" id="inputUno"><input type="text" id="inputDos"><br>
    <table id="table" border='1'>
        <tr>
            <td class="col1" width='100px'>a</td>
            <td class="col2" width='100px'>b</td>
        </tr>
        <tr>
            <td class="col1" width='100px'>c</td>
            <td class="col2" width='100px'>d</td>
        </tr>
        <tr>
            <td class="col1" width='100px'>c</td>
            <td class="col2" width='100px'>f</td>
        </tr>
    </table>

    I think, humbly, that logic is wrong. For the following reasons:

  • The deletion of rows that do not comply should be done at the time of exporting the table and not before . Otherwise, if you modify the filters, the rows that you had previously fulfilled now do not exist anymore.

  • Let's think that you implemented the above and the rows are not deleted but they are marked to be deleted when exporting. Your filter should be a condition AND , but in the way you have set it, the following flow can occur:

    • You write a in the first input. Rows 2 and 3 are marked to delete.
    • You write d in the second input. Now row 1 is marked to eliminate (because its column 2 does not contain d ) but rows 2 and 3 are marked as if they met the filter. Basically, you just ignored filter 1 because you only checked compliance with filter 2. You can not detect this with your current approach because the row is deleted and it seems to be a AND filter, but in reality the last input you receive a keyup affects the entire table.

  • When exporting the table, it is not enough to make the td element empty. You should remove it completely. Maybe the export is working well, but in my view, a td gives rise to a row (in the excel) and each cell gives rise to a column. Ergo, your XLS can have blank rows. You should do a remove() instead of a empty() .

    • I leave you an implementation that I think best represents what you want to do:

    • Each time you write something in any of the two inputs, run the two checks. Mark with a class no_cumple the cells that do not comply (letters in red) and a class cumple (letters in green) those that comply. This way, you can distinguish exactly what the filter is doing.
    • For each row, those that contain at least one cell with that class are marked with the class fila_eliminar (red border). Only those that do not contain any cells that do not comply with the filters will be saved from the final butcher shop.

    With this approach, when exporting you put: 

    $('#table').find('.fila_eliminar').remove();

    Take a look at this snippet: 

    $(document).ready(function() {

  $('#inputUno, #inputDos').keyup(function() {
    var cont1 = $('#inputUno').val().trim(),
      cont2 = $('#inputDos').val().trim(),
      tabla = $('#table');

    tabla.find('td.col1:contains(' + cont1 + ')')
      .removeClass('no_cumple')
      .addClass('cumple');

    tabla.find('td.col2:contains(' + cont2 + ')')
      .removeClass('no_cumple')
      .addClass('cumple');


    tabla.find('td.col1:not(:contains(' + cont1 + '))')
      .addClass('no_cumple')
      .removeClass('cumple');


    tabla.find('td.col2:not(:contains(' + cont2 + '))')
      .addClass('no_cumple')
      .removeClass('cumple');

    tabla.find('tr').removeClass('fila_eliminar').find('.col3').text('se queda');
    tabla.find('tr .no_cumple').each(function() {
      $(this).parent().addClass('fila_eliminar').find('.col3').text('se borra');
    });

  });

});
    .no_cumple {
  color: red;
}

.cumple {
  color: green;
}

.fila_eliminar {
  border: 2px solid red;
}

.fila_eliminar .col3 {
  color: red;
  font-weight: bold;
}
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<table id="table" border='1'>
  <thead>
    <th>
      <input type="text" id="inputUno" placeholder="texto a filtrar">

      <td class="col2" width='100px'>f</td>
      <td class="col3" width='100px'>se queda</td>
    </tr>
  </tbody>
</table>

    Edit, reformulated objective:

    According to your reformulated objective, filter B only operates on the rows that survived filter A. In the solution that I put to you this is implicitly achieved because given a combination of A and B that discards all the rows, none qualifies for the export.

    But if you want the user to filter first for A and then for B, if in B you put something that just is not among the rows that survived, nothing happens. In this case the flow could be:

    • I use two <tbody> elements. The first contains the rows that do not comply and the second those that do. The filters move the rows from <tbody> to the other.
    • Filter B part deactivated
    • I put something in filter A, and some rows qualify
    • Filter B is unlocked
    • I put something in the filter B and
      • If some rows qualify, filter B is applied in conjunction with the A
      • If none qualify, filter B has no effect
      • If you empty filter B, filter A is applied again only
      • If you empty filter A, everything goes back to the beginning
    • At the time of export, I eliminate the <tbody> of those that do not comply. 

    $(document).ready(function() {


  $('#inputUno').keyup(function() {
    var cont1 = $('#inputUno').val().trim(),
      tabla = $('#table');


    tabla.find('td.col1:contains(' + cont1 + ')')
      .parent()
      .appendTo('#filas_cumplen');

    tabla.find('td.col1:not(:contains(' + cont1 + '))')
      .parent()
      .appendTo('#filas_no_cumplen');

    tabla.find('#filas_cumplen').find('.col3').text('se queda');
    tabla.find('#filas_no_cumplen').find('.col3').text('se borra');
    $('#inputDos').removeAttr('disabled').attr('placeholder', 'texto a filtrar').val('');

    if (cont1 === '') {
      $('#inputDos').val('').attr('disabled', true).attr('placeholder', 'debe llenar primer filtro')

    }
  });

  $('#inputDos').on('keyup', function() {
    var cont2 = $('#inputDos').val().trim(),
      tbody = $('#filas_cumplen'),
      tabla = $('#table');

    if (cont2 === '') {
      $('#inputUno').keyup();
      return;
    }
    var cumplen = tbody.find('td.col2:contains(' + cont2 + ')');
    if (cumplen.length === 0) {
      return;
    }
    tbody.find('td.col2:not(:contains(' + cont2 + '))')

    I present an alternative using Javascript Vanilla.

    It uses setAttribute and getAttribute, as well as querySelectorAll. Explain the functionality with comments in the code 

    window.onload = function () {
	//Se le da el attributo hiddenbyfilter a todas las filas de la tabla
	let rows = document.querySelectorAll("#table tr");
	for (let i=0; i < rows.length; i++) rows[i].setAttribute("hiddenByFilter", 0);
	
	//Se asigna la funcion de filtrado al evento keyup 
	let input_1 = document.querySelector("#inputUno");
	input_1.addEventListener("keyup", filter);
	
	let input_2 = document.querySelector("#inputDos");
	input_2.addEventListener("keyup", filter);

}

function filter () {
		//this -> corresponde al input en el cual se da el evento keyup
		//Valor del input
		let searchValue = this.value;
		//Listado de las filas de la tabla (tr)
		let rows = document.querySelectorAll("#table tr");
		//Indicador de que columna debe filtrar el input
		let filterForColumn = this.getAttribute("filterForColumn");

		for (let i=0; i < rows.length; i++){
			//Si la fila no tiene filtro o si el nuevo filtro tiene precedencia
			if (rows[i].getAttribute("hiddenByFilter") == 0 ||
					filterForColumn <= rows[i].getAttribute("hiddenByFilter")
			){
				//Se aplica filtro a la fila
				rows[i].setAttribute("hiddenByFilter", filterForColumn);
				//Se obtiene la celda (td)
				let cell = rows[i].querySelector("td:nth-child("+filterForColumn+")");
				//Si el texto de la celda es igual al buscado o si el valor buscado es vacio
				if (cell.innerText == searchValue || searchValue === "") {
					//Se quita el filtro de la fila
					rows[i].setAttribute("hiddenByFilter", 0);
				}
			}
		}		
}
    /*Muestra solo los que tengan el atributo hiddenbyfilter en 0*/
tr:not([hiddenByFilter="0"]) {
	display:none;
}
    <input type="text" id="inputUno" filterForColumn="1"><input type="text" id="inputDos" filterForColumn="2"><br>
<table id="table" border='1'>
		<tr>
				<td class="col1" width='100px'>a</td>
				<td class="col2" width='100px'>b</td>
		</tr>
		<tr>
				<td class="col1" width='100px'>c</td>
				<td class="col2" width='100px'>d</td>
		</tr>
		<tr>
				<td class="col1" width='100px'>c</td>
				<td class="col2" width='100px'>f</td>
		</tr>
</table>

    As you comment to require to remove from the DOM the results that do not match the search, you could alter the filter function by something similar to: 

    function filter () {
    let searchValue = this.value;
    let rows = document.querySelectorAll("#table tr");
    let filterForColumn = this.getAttribute("filterForColumn");

    for (let i=0; i < rows.length; i++){
        if (rows[i].getAttribute("hiddenByFilter") == 0){
            let cell = rows[i].querySelector("td:nth-child("+filterForColumn+")");
            if ( cell.innerText != searchValue ) {
                rows[i].remove();
            }
        }
    }   
}

    I hope it helps you.

    I recommend you use the DataTable library, which allows you to sort by column, pagination, is responsive and provides export to Csv, pdf, excel etc ..

    The example I have added allows you to write by column or in a general way 

    $(document).ready(function() {
    $('#example tfoot th').each( function () {
        var title = $(this).text();
        $(this).html( '<input type="text" placeholder="Buscar'+title+'" />' );
    } );
 
 
    var table = $('#example').DataTable({
"language": {
        search: 'Buscar:',
        "lengthMenu": "Mostrando _MENU_ registros por pagina",
        "zeroRecords": "Sin datos",
        "info": "Mostrando _PAGE_ de _PAGES_",
        "infoEmpty": "Sin registros",
        "infoFiltered": "(filtrados de _MAX_)",
paginate: {
    first: 'Primero',
    previous: 'Anterior',
    next: 'Siguiente',
    last: 'Último',
  }
    }
});
    table.columns().every( function () {
        var that = this;
 
        $( 'input', this.footer() ).on( 'keyup change', function () {
            if ( that.search() !== this.value ) {
                that
                    .search( this.value )
                    .draw();
            }
        } );
    } );
} );
    tfoot input {
        width: 100%;
        padding: 3px;
        box-sizing: border-box;
    }
