How to iterate columns in datatable using jQuery? [duplicate] - php

Question

I am using jquery plugin DataTables for building nice table
var table = $('#example').DataTable({
"data": source
});
I would like that make an each for all rows in table
Unfortunately this way may be out of date and does't work with new version (it launchs an error)
$(table.fnGetNodes()).each(function () {
});
And this way only works only for visibles rows (10 first rows because other rows are paginated)
table.each( function ( value, index ) {
console.log( 'Data in index: '+index+' is: '+value );
} );
Do you known how to loop to all rows please?

Answer 1

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

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

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.
});

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);
}
});
