Как переделать запросом JavaScript?

$('body').on('submit', '.aj-form', function() { 
 
    var url = $(this).attr('action'), 
        arrInfa = $(this).data('infa').split(/\s*,\s*/); 
    if(status_form == '0'){ 
      status_form = 1; 
      $.ajax({      	 
        url: url, 
      	type: 'POST', 
      	data: $(this).serialize(), 
      	dataType: 'script', 
      	beforeSend: function (){ 
      	  if(arrInfa[0]){ 
      	    var text_load = $(arrInfa[1]).html(); 
      	    $(arrInfa[1]).data('html',text_load).html(arrInfa[2]); 
      	  } 
      	}, 
        error: function (infa){status_form = 0;}, 
        success: function (infa){  
        	if(arrInfa[0]){ 
      	    var data_load = $(arrInfa[1]).data('html'); 
      	    $(arrInfa[1]).html(data_load); 
      	  } 
          status_form = 0; 
        } 
      }); 
    } 
     
    return false; 
 
  });
