jQuery table sort

Question

I have a very simple HTML table with 4 columns:

Facility Name, Phone #, City, Specialty

I want the user to be able to sort by Faci

Answer 1

I came across this, and thought I'd throw in my 2 cents. Click on the column headers to sort ascending, and again to sort descending.

• Works in Chrome, Firefox, Opera AND IE(8)
• Only uses JQuery
• Does alpha and numeric sorting - ascending and descending

$('th').click(function(){
    var table = $(this).parents('table').eq(0)
    var rows = table.find('tr:gt(0)').toArray().sort(comparer($(this).index()))
    this.asc = !this.asc
    if (!this.asc){rows = rows.reverse()}
    for (var i = 0; i < rows.length; i++){table.append(rows[i])}
})
function comparer(index) {
    return function(a, b) {
        var valA = getCellValue(a, index), valB = getCellValue(b, index)
        return $.isNumeric(valA) && $.isNumeric(valB) ? valA - valB : valA.toString().localeCompare(valB)
    }
}
function getCellValue(row, index){ return $(row).children('td').eq(index).text() }

table, th, td {
    border: 1px solid black;
}
th {
    cursor: pointer;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
    <tr><th>Country</th><th>Date</th><th>Size</th></tr>
    <tr><td>France</td><td>2001-01-01</td><td>25</td></tr>
    <tr><td><a href=#>spain</a></td><td>2005-05-05</td><td></td></tr>
    <tr><td>Lebanon</td><td>2002-02-02</td><td>-17</td></tr>
    <tr><td>Argentina</td><td>2005-04-04</td><td>100</td></tr>
    <tr><td>USA</td><td></td><td>-6</td></tr>
</table>

My vote! jquery.sortElements.js and simple jquery
Very simple, very easy, thanks nandhp...

            $('th').live('click', function(){

            var th = $(this), thIndex = th.index(), var table = $(this).parent().parent();

                switch($(this).attr('inverse')){
                case 'false': inverse = true; break;
                case 'true:': inverse = false; break;
                default: inverse = false; break;
                }
            th.attr('inverse',inverse)

            table.find('td').filter(function(){
                return $(this).index() === thIndex;
            }).sortElements(function(a, b){
                return $.text([a]) > $.text([b]) ?
                    inverse ? -1 : 1
                    : inverse ? 1 : -1;
            }, function(){
                // parentNode is the element we want to move
                return this.parentNode; 
            });
            inverse = !inverse;     
            });

Dei uma melhorada do código
One cod better! Function for All tables in all Th in all time... Look it!

If you want to avoid all the bells and whistles then may I suggest this simple sortElements plugin. Usage:

var table = $('table');

$('.sortable th')
    .wrapInner('<span title="sort this column"/>')
    .each(function(){

        var th = $(this),
            thIndex = th.index(),
            inverse = false;

        th.click(function(){

            table.find('td').filter(function(){

                return $(this).index() === thIndex;

            }).sortElements(function(a, b){

                if( $.text([a]) == $.text([b]) )
                    return 0;

                return $.text([a]) > $.text([b]) ?
                    inverse ? -1 : 1
                    : inverse ? 1 : -1;

            }, function(){

                // parentNode is the element we want to move
                return this.parentNode; 

            });

            inverse = !inverse;

        });

    });

And a demo. (click the "city" and "facility" column-headers to sort)

Answer 4

You can use a jQuery plugin (breedjs) that provides sort, filter and pagination:

HTML:

<table>
  <thead>
    <tr>
      <th sort='name'>Name</th>
      <th>Phone</th>
      <th sort='city'>City</th>
      <th>Speciality</th>
    </tr>
  </thead>
  <tbody>
    <tr b-scope="people" b-loop="person in people">
      <td b-sort="name">{{person.name}}</td>
      <td>{{person.phone}}</td>
      <td b-sort="city">{{person.city}}</td>
      <td>{{person.speciality}}</td>
    </tr>
  </tbody>
</table>

JS:

$(function(){
  var data = {
    people: [
      {name: 'c', phone: 123, city: 'b', speciality: 'a'},
      {name: 'b', phone: 345, city: 'a', speciality: 'c'},
      {name: 'a', phone: 234, city: 'c', speciality: 'b'},
    ]
  };
  breed.run({
    scope: 'people',
    input: data
  });
  $("th[sort]").click(function(){
    breed.sort({
      scope: 'people',
      selector: $(this).attr('sort')
    });
  });
});

Answer 5

To the response of James I will only change the sorting function to make it more universal. This way it will sort text alphabetical and numbers like numbers.

if( $.text([a]) == $.text([b]) )
    return 0;
if(isNaN($.text([a])) && isNaN($.text([b]))){
    return $.text([a]) > $.text([b]) ? 
       inverse ? -1 : 1
       : inverse ? 1 : -1;
}
else{
    return parseInt($.text([a])) > parseInt($.text([b])) ? 
      inverse ? -1 : 1
      : inverse ? 1 : -1;
}

Answer 6

Another approach to sort HTML table. (based on W3.JS HTML Sort)

/* Facility Name */
$('#bioTable th:eq(0)').addClass("control-label pointer");
/* Phone # */
$('#bioTable th:eq(1)').addClass("not-allowed");
/* City */
$('#bioTable th:eq(2)').addClass("control-label pointer");
/* Specialty */
$('#bioTable th:eq(3)').addClass("not-allowed");


var collection = [{
  "FacilityName": "MinION",
  "Phone": "999-8888",
  "City": "France",
  "Specialty": "Genetic Prediction"
}, {
  "FacilityName": "GridION X5",
  "Phone": "999-8812",
  "City": "Singapore",
  "Specialty": "DNA Assembly"
}, {
  "FacilityName": "PromethION",
  "Phone": "929-8888",
  "City": "San Francisco",
  "Specialty": "DNA Testing"
}, {
  "FacilityName": "iSeq 100 System",
  "Phone": "999-8008",
  "City": "Christchurch",
  "Specialty": "gDNA-mRNA sequencing"
}]

$tbody = $("#bioTable").append('<tbody></tbody>');

for (var i = 0; i < collection.length; i++) {
  $tbody = $tbody.append('<tr class="item"><td>' + collection[i]["FacilityName"] + '</td><td>' + collection[i]["Phone"] + '</td><td>' + collection[i]["City"] + '</td><td>' + collection[i]["Specialty"] + '</td></tr>');
}

.control-label:after {
  content: "*";
  color: red;
}

.pointer {
  cursor: pointer;
}

.not-allowed {
  cursor: not-allowed;
}

<script src="https://www.w3schools.com/lib/w3.js"></script>
<link href="https://www.w3schools.com/w3css/4/w3.css" rel="stylesheet" />
<p>Click the <strong>table headers</strong> to sort the table accordingly:</p>

<table id="bioTable" class="w3-table-all">
  <thead>
    <tr>
      <th onclick="w3.sortHTML('#bioTable', '.item', 'td:nth-child(1)')">Facility Name</th>
      <th>Phone #</th>
      <th onclick="w3.sortHTML('#bioTable', '.item', 'td:nth-child(3)')">City</th>
      <th>Specialty</th>
    </tr>
  </thead>
</table>
