How can I duplicate a row in DataTables (jQuery DataTables plugin)? - javascript

I found out how to delete a row with this jQuery code. While clicking on a td with the class delete and a garbage icon.
HTML
<table id="foo" class="display" cellspacing="0" width="100%">
<tbody>
<tr>
<td>Foo1</td>
<td>Foo2</td>
<td>Foo3</td>
<td class="delete">IMAGE src here</td>
<td><img src="http://placehold.it/20x20"></td>
</tr>
</tbody>
JAVASCRIPT
$('#foo tbody').on( 'click', 'tr .delete', function () {
$(this).closest('tr').fadeOut("slow", function(){
$(this).remove();
})
} );
But I did not find anything about duplicating rows. I just want to click on a td with another icon in it and the row is duplicated below.

To duplicate a row, you'll need to copy all of its data into an array, then call row.add() to insert this data as a new row.
Something like:
<table id="foo" class="display" cellspacing="0" width="100%">
<tbody>
<tr>
<td>Foo1</td>
<td>Foo2</td>
<td>Foo3</td>
<td class="delete">IMAGE src here</td>
<td class="copy">IMAGE src here</td>
<td><img src="http://placehold.it/20x20"></td>
</tr>
</tbody>
$('#foo tbody').on( 'click', 'tr .copy', function () {
var row_data = [];
$(this).closest('tr').find('td').each(function() {
row_data.push($(this).text());
});
// you'll need a reference to your DataTable here
table.row.add(row_data).draw();
});
To get a reference to your DataTable, assign the result of the DataTable() method to a var.
$(document).ready(function() {
var table = $('#foo).DataTable( { "paging": false, "info": false });
// set up your event handlers, etc.
});
If you append a row with jQuery instead of DataTables method like row.add(), you'll lose the row when you sort or page the table.

Here's the jQuery that adds a row duplicate right underneath it, where DataTables is concerned. It has a caveat that this method may not retain any sorting or filtering set by the user.
$('#formtable tbody').on( 'click', 'button.btn-success', function () {
//destroy instance of DataTables
table.destroy(false);
//script assumes button is clicked on the line that needs to be duplicated
var btn = this;
//copy and insert row right below the original
var line = $(btn).parents('tr');
line.after(line.clone());
//since clone retains only input field values, but not dropdown selections,
//each dropdown value must be assigned individually
line.next().find("select.shape").val(line.find("select.shape").val());
line.next().find("select.material").val(line.find("select.material").val());
line.next().find("select.supplied").val(line.find("select.supplied").val());
//re-creating DataTables instance
//notice that "table" has no "var" in front - that's because it is pre-defined.
table = $('#formtable').DataTable({
"columnDefs": [ {
"searchable": false,
"orderable": false,
"targets": "_all"
} ],
"paging": false,
"info": false,
"ordering": true,
"searching": false,
"rowReorder": true
});
//"Index Column" values re-calculation
table.column(0).nodes().each( function (cell, i) {
cell.innerHTML = i+1;
});
});
Hope this helps.

Try this:
HTML
<table id="foo" class="display" cellspacing="0" width="100%">
<tbody>
<tr>
<td>Foo1</td>
<td>Foo2</td>
<td>Foo3</td>
<td class="delete">IMAGE src here</td>
<td class="duplicate"><img src="http://placehold.it/20x20"></td>
</tr>
</tbody>
</table>
SCRIPT
$('#foo tbody').on( 'click', 'tr .delete', function () {
$(this).closest('tr').fadeOut("slow", function(){
$(this).remove();
})
} );
$('#foo tbody').on( 'click', 'tr .duplicate', function () {
var myTr = $(this).closest('tr');
var clone = myTr.clone();
myTr.after(clone);
} );

Get element attribute with .each loop

I have a simple example table that has data attributes for every table row.
<table id="example">
<tr data-sample="1">
<th>Fox</th>
<th>Sam</th>
<th>Ted</th>
</tr>
<tr data-sample="2">
<td>Bill</td>
<td>Nick</td>
<td>Pal</td>
</tr>
<tr data-sample="3">
<td>El</td>
<td>Pal</td>
<td>Tea</td>
</tr>
</table>
I'm trying to get all data-sample attributes with the following code:
('#example tr').each(function () {
console.log(this.data('sample'));
});
JSfiddle
And I'm getting a "this.data is not a function" error. This gets me to the point that in .each jquery loop this returns a DOM element, not a function or whatever I can use a a selector (if I just print out this, I get a list of table rows and their children). Is there any way to get this as a selector? ('#example').children('tr') and ('#example').find('tr') give the same result.
Jquery syntax error
this not jquery object .Do with $(this).data('sample')
$('#example tr').each(function () {
console.log($(this).data('sample'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
I have a simple example table that has data-attributes for every table row.
<table id="example">

<tr data-sample="2">

<tr data-sample="3">

</tr>
</table>
Or do with attr()
$('#example tr').each(function () {
console.log($(this).attr('data-sample'));
});
There are two issue in you code:
1) you need to convert DOM object to jquery object for using with .data()
2) you are passing wrong property argument in .data(). it should be sample:
$('#example tr').each(function () {
console.log($(this).data('sample'));
});
There are 2 way to do this -
#1
$('#example tr').each(function () {
console.log($(this).data('sample'));
});
#2
$('#example tr').each(function () {
console.log($(this).attr('data-sample'));
});
Check this
$(document).ready(function(){
$('#example tr').each(function () {
console.log($(this).attr("data-sample"));
});
});
If you want to get row content use this
$('#example tr').each(function (i) {
alert($('#example tr[data-sample]')[i].innerText.split("\t"));
});

Adding select menu to multiple tables with jquery data tables pluglin

I've got two tables (table1,table2) that are structurally the same, but fed from different sources. Both tables share the class 'display' which I use to initialise the plugin for both tables. This works great for the most part, however the column filters select menu for table2 is duplicated on table1.
I've tried to fix this by using 'this' keyword to indicate a particular instance of the toolbar each of the filters need applying to, but not had much success.
The code that works is:
HTML:
<table id="table1" class="display table-striped table-borded table-hover" cellspacing="0" width="100%">
<thead>
<tr>
<th>Report Name</th>
<th>Year</th>
<th>Montly Snapshot</th>
</tr>
</thead>
<tfoot>
<tr>
<th>Date of Last Refresh --var from warehouse-- </th>
</tr>
</tfoot>
</table>
<table id="table2" class="display table-striped table-borded table-hover" cellspacing="0" width="100%">
<thead>
<tr>
<th>Report Name</th>
<th>Year</th>
<th>Montly Snapshot</th>
</tr>
</thead>
<tfoot>
<tr>
<th>Date of Last Refresh --var from warehouse-- </th>
</tr>
</tfoot>
</table>
JS:
//initialise data tables plugin and apply custom settings.
var reportstable = $('table.display').DataTable({
"sDom": '<"toolbar">Bfrtlp',
"searchCols": [
null, {
'sSearch': 'Current'
}
],
language: {
search: "_INPUT_",
searchPlaceholder: "Search for a Report..."
},
// create select form controls
initComplete: function() {
this.api().columns([1, 2]).every(function() {
var column = this;
var select = $('<select><option value=""></option></select>')
.appendTo($('.toolbar'))
.on('change', function() {
var val = $.fn.dataTable.util.escapeRegex(
$(this).val()
);
column
.search(val ? '^' + val + '$' : '', true, false)
.draw();
});
column.data().unique().sort().each(function(d, j) {
select.append('<option value="' + d + '">' + d + '</option>')
if ($('#info').css('display') == 'block') {
$("#reports_wrapper").css('display', 'none');
}
// add bootstrap classes and placeholder property to form controls to add style
$('.toolbar select').addClass('selectpicker');
$('.dt-button').addClass('btn btn-danger').removeClass('dt-button');
$('.toolbar select').attr('id', 'year');
$('#year').prop('title', 'Financial Year');
$("#year option:contains('Current')").remove();
$('.toolbar select:nth-of-type(2)').attr('id', 'month');
$('#month').prop('title', 'Monthy Snapshot');
$("#month option:contains('undefined')").remove();
});
});
},
// create clear filter button
buttons: [
{
text: 'Clear Filters',
action: function(e, dt, node, config) {
$('select').val('').selectpicker('refresh');
// set Current Year as default filter
reportstable
.search('')
.columns([1]).search('Current')
.columns([2]).search('')
.draw();
}
}
],
//hide specified columns
"columnDefs": [
{
"targets": [1],
"visible": false,
"searchable": true
}, {
"targets": [2],
"visible": false,
"searchable": true
}
]
});
I've updates your jsfiddle and created a new jsfiddle. It's now appending 2 select menus in both tables's wrapper div. I've found why it's appending 4 select menus instead of 2 on the table1's wrapper div. It's because of this code: .appendTo($('.toolbar')). When initComplete callback function is called for table1 there is only one div with class=toolbar, and when the initComplete callback function is called for table2 there is two div with class=toolbar, one in table1's wrapper div and one in table2's wrapper div. that's why on table2's initComplete callback function it append select menus to all divs with class=toolbar. We should rather append to the current table wrapper's div with class=toolbar.

Highlight some rows of my table in javascript

I need to highlight some rows of my table. This highlight is based on the rows present in my response object. This object can be as follow:
<table id="ListRequests" class="table table-striped">
<tbody>
<tr id="13955">
<td>JEAN DUPONT</td>
<td>ACLIMEX SPRL</td>
</tr>
</tbody>
</table>
Here is my javascript code:
var id = $("tbody tr", response).attr('id');
var cols = $('#' + id + ' td');
cols.effect("highlight", {}, 30000);
This works fine only if my response object contains only 1 row. Now I need to be able to highlight more than 1 rows at a time. So for example with the response object below:
<table id="ListRequests" class="table table-striped">
<tbody>
<tr id="13955">
<td>JEAN DUPONT</td>
<td>ACLIMEX SPRL</td>
</tr>
<tr id="13954">
<td>MIKE GIVER</td>
<td>ARGO INTERNATIONAL CORP</td>
</tr>
</tbody>
</table>
Any idea how to adapt my javascript code for that purpose ?
If you really want to do it the way you are doing it, than you need to use each
var trs = $("tbody tr", response);
trs.each( function () {
var id = this.id,
cols = $('#' + id + ' td');
cols.effect("highlight", {}, 30000);
});
Better off returning a JSON object with ids to select.
attr returns a single value, regardless how many elements are matched by the proceeding selector.
If you want to map every selected element to an ID and return array, you need map:
var ids = $("tbody tr", response).map(function (i, e) { return $(e).attr('id'); });
Once you have your list of IDs, you can iterate over that list, and highlight the matching rows in the DOM:
ids.forEach(function (id) {
var cols = $('#' + id + ' td');
cols.effect("highlight", {}, 30000);
});
Here is a working snippet.
The idea is to scrap the ids from the response you get by looping the tr nodes, from these ids build a css selector for the nodes you are interested in, and finally highlight all them.
function highlight(response){
// retrieve the ids from the response
var ids = $(response).find("tbody tr").map(function(){
// `this` will be the trs one after the other.
// `map` will put all returned values in an array.
return this.getAttribute("id");
}).get();
// build the css selector
var selector = "#" + ids.join(",#");
// highlight the corresponding nodes
$(selector).effect("highlight", {}, 30000);
}
// Call highlight with your response example.
highlight('<table id="ListRequests" class="table table-striped"><tbody><tr id="13955"><td>JEAN DUPONT</td><td>ACLIMEX SPRL</td></tr><tr id="13954"><td>MIKE GIVER</td><td>ARGO INTERNATIONAL CORP</td></tr></tbody></table>');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://code.jquery.com/ui/1.11.4/jquery-ui.min.js"></script>
<table id="ListRequests" class="table table-striped">
<tbody>
<tr id="13955">
<td>JEAN DUPONT</td>
<td>ACLIMEX SPRL</td>
</tr>
<tr id="13954">
<td>MIKE GIVER</td>
<td>ARGO INTERNATIONAL CORP</td>
</tr>
<tr id="1211">
<td>OTHER ONE</td>
<td>MUSN'T BE HIGHLIGHTED</td>
</tr>
</tbody>

How to update DataTables DOM?

I am using Datatables for a review system, An user can grade each item by clicking on stars(1 to 5).
<table cellpadding="0" cellspacing="0" border="0" class="table table-striped table-bordered" id="tabela-disciplinas-preferencia">
<thead>
<tr>
<th>Semestre</th>
<th>Curso</th>
<th>Disciplina</th>
<th>Nível de Interesse</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Engenharia de Software</td>
<td>Redes</td>
<td>
<div class="rating" valor="0">
<span valor="5">☆</span><span valor="4">☆</span><span valor="3">☆</span><span valor="2">☆</span><span valor="1">☆</span>
</div>
</td>
</tr>
....
</tbody>
</table>
My JS
$(document).ready(function() {
$('#tabela-disciplinas-preferencia').dataTable( {
"sPaginationType": "bootstrap"
} );
});
However when an user click to grade one item, I change valor attribute in rating div but datatables doesn't update their values internally.
Click rating event
$(document).ready(function() {
$('div.rating span').click(function(){
starR= new StarRating( $(this).parent());
starR.changeValue($(this).attr('valor'));
//Get TR Element
aPos = oTable.fnGetPosition( $(this).parent().parent().get(0) );
aData = oTable.fnGetData( aPos[0] );
//Get rating div
rating = aData[3];
aData[3] = $(rating).attr('valor', $(this).attr('valor'));
// ????
oTable.fnUpdate(aData[3]);
});
});
How can I update datatables DOM? I already got data and changed value but how can I update back to oTable?
Changing values and inserting back to aData already update oTable
$('div.rating span').click(function(){
starR= new StarRating($(this).parent());
starR.changeValue($(this).attr('valor'));
//update oTable row data
aPos = oTable.fnGetPosition( $(this).parent().parent().get(0) );
aData = oTable.fnGetData( aPos[0] );
aData[3] = $(aData[3]).attr('valor', starR.getValue());
});
That's solution I have found and seems working pretty well.
I know it's been a minute, but a simple alternative.
$('div.rating span').click(function () {
//Invalidate Row after DOM manipulation
var parentRow = $(this).closest('tr');
$('#your-table').DataTable().row(parentRow).invalidate().draw();
}
You can invalidate row(s) or column(s) that have been changed and the table will update itself. This method will keep search criteria intact.

Jquery Datatables - Make whole row a link

This maybe simple, but cant seem to figure it out. Using jquery datatables how can I make each row clickable to just link to a normal page? So if someone moused over any of the row the whole row will hightlight and be clickable and link to whatever url I would want it to link to when clicked.
I've use the fnDrawCallback parameter of the jQuery Datatables plugin to make it work. Here is my solution :
fnDrawCallback: function () {
$('#datatable tbody tr').click(function () {
// get position of the selected row
var position = table.fnGetPosition(this)
// value of the first column (can be hidden)
var id = table.fnGetData(position)[0]
// redirect
document.location.href = '?q=node/6?id=' + id
})
}
Hope this will help.
This did it for me using the row callback.
fnRowCallback: function(nRow, aData, iDisplayIndex, iDisplayIndexFull) {
responsiveHelper.createExpandIcon(nRow);
$(nRow).click(function() {
document.location.href = 'www.google.com';
});
},
$('#myTable').on( 'click', 'tbody tr', function () {
window.location.href = $(this).data('href');
});
where #myTable is the ID of the table, and you need put the href in the tr, like that:
<tr data-href="page.php?id=1">
<th>Student ID</th>
<th>Fullname</th>
<th>Email</th>
<th>Phone</th>
<th>Active</th>
</tr>
It's simple enough to do this with a vanilla <table>, but I don't see why this wouldn't work with a jQuery DataTables one either.
$('#myTableId').on('click', 'tbody > tr > td', function ()
{
// 'this' refers to the current <td>, if you need information out of it
window.open('http://example.com');
});
You'll probably want some hover event handling there as well, to give users visual feedback before they click a row.
You can also use the DataTables plugins api which allows you to create custom renderers.
Very cool: JS addon here
And using the fnDrawCallback
fnDrawCallback: function() {
this.rowlink();
},
You can do that to make row clickable :
<script type="text/javascript">
var oTable;
$(document).ready(function() {
oTable = $('#myTable').dataTable({
"ajax" : "getTable.json",
"fnInitComplete": function ( oSettings ) {
//On click in row, redirect to page Product of ID
$(oTable.fnGetNodes()).click( function () {
var iPos = oTable.fnGetPosition( this );
var aData = oSettings.aoData[ iPos ]._aData;
//redirect
document.location.href = "product?id=" + aData.id;
} );
},
"columns" : [ {
"data" : "id"
}, {
"data" : "date"
}, {
"data" : "status"
}]
});
});
</script>
<table id="myTable" class="display" cellspacing="0" width="100%">
<thead>
<tr>
<th>#</th>
<th>Date</th>
<th>Status</th>
</tr>
</thead>
<tbody></tbody>
</table>
I think it will be like that
$('#invoice-table').dataTable({
"fnRowCallback": function (nRow, aData, iDisplayIndex, iDisplayIndexFull) {
var slug = $(nRow).data("slug");
$(nRow).attr("href", "/invoices/" + slug + "/");
$(nRow).css( 'cursor', 'pointer' );
$(nRow).click(function(){
window.location = $(this).attr('href');
return false;
});
}
});
And the table row like that
<tr class="invoice_row" data-slug="{{ invoice.slug }}">
<td>{{ invoice.ref }}</td>
<td>{{ invoice.campaign.name }}</td>
<td>{{ invoice.due_date|date:'d-m-Y' }}</td>
<td>{{ invoice.cost }}</td>
<td>
<span class="label label-danger">Suspended</span>
</td>
</tr>
This worked fine with me
**I have used a simple solution for this. Add onclick on tr and you are done. Tested with jquery datatable **
<tr onclick="link(<?php echo $id; ?>)">
function link(id){
location.href = '<?php echo $url ?>'+'/'+id;
}
Recently I had to deal with clicking a row in datatables.
$(document).ready(function() {
$("#datatable tbody tr").live( 'click',function() {
window.open('http://www.example.com');
} );
} );
