jquery - Why does a button and a keypress with same function work different? -


i want achieve same result in keypress event "enter" works me on button , somehow keypress duplicates information based on number of times "enter" pressed.

first time shows information correctly , 2nd time doubled, 3rd time 3 times, etc...

$(document).on('keypress', '.dataa', function (event) {     if (event.which === 13) {         event.preventdefault();         save_data();     } });

and function works correctly if used on button:

function save_data() {     var final='';     var datas='';     var spans=$("body").find('#'+pruebaa).attr("data");     $(".dataa").each(function() {                if(!!$(this).val()){             datas+=$(this).val()+"-";         }     });     final=spans+datas;     $(".tabla").remove();     dlg.remove();     $("body").find('#'+pruebaa).attr("data",final); }

the problem seems data's part since part doubled 2nd time, tripled 3rd, etc...
