How to loop through all rows in DataTables jQuery?

Question

I am using jquery plugin DataTables for building nice table

  var table = $(\'#example\').DataTable({
    \"data\": source
});

Answer 1

If you are using the legacy DataTables then you can get all the rows even the paginated ones, as shown below...

table.fnGetNodes(); // table is the datatables object.

So we can loop through the rows by using .each() method provided by jQuery.

jQuery(table.fnGetNodes()).each(function () {
// You can use `jQuery(this).` to access each row, and process it further.            
});

Answer 2

Datatables have an iterator for each row rows().every() with this referring to the context of the current row being iterated.

tableName.rows().every(function(){
    console.log(this.data());
});

Answer 3

for example, this data has three fields UserID, UserName and isActive and we want to show only active users The following code will return all the rows.

var data = $('#myDataTable').DataTable().rows.data();

We will print only active users

data.each(function (value, index) {
  if (value.isActive)
  {
     console.log(value.UserID);
     console.log(value.UserName);
  }
});

Answer 4

I finally found:

 var data = table.rows().data();
 data.each(function (value, index) {
     console.log(`For index ${index}, data value is ${value}`);
 });
