javascript - jQuery .each best practice to format and send via ajax -

what best practice run .each , send value array via ajax.

 $( ".sortable li" ).each(function( index ) {       console.log($(this).data("trackid"));  }); 

this output in console window 11,2,45,23,4,31.

well use push method add id's array. i've posted array php , works well.

 var thearray = [];  $( ".sortable li" ).each(function( index ) {      thearray.push($(this).data("trackid"));  });   // send via ajax  $.post(url,{ids:thearray},function(response){      // code handle response  });
