javascript - jQuery: Do I need both keyUp and change events? -


i have page 2 forms; each form has input text field;

the value found in input text of 1st form must same value found in input text of 2nd form;

when value chages, other input text field modifies value;

should use both onkeyup , onchange events?

if not, wich 1 right 1 use?

i asking because seams have 2 post requests, , think why.

   $('input.searchbox').keyup( function(){        $('input.txtfieldsearch').val($('input.searchbox').val());        listviewupdate();        $('input.txtfieldsearch').trigger("keyup");    });      $('input.txtfieldsearch').keyup( function(){        $('input.searchbox').val($('input.txtfieldsearch').val());        listviewupdate();     });     $('input.searchbox').change( function(){        $('input.txtfieldsearch').val($('input.searchbox').val());        listviewupdate();        $('input.txtfieldsearch').trigger("change");    });      $('input.txtfieldsearch').change( function(){        $('input.searchbox').val($('input.txtfieldsearch').val());        listviewupdate();     });

you can use $.on() function , attach multiples handlers.

$("#element").on('keyup change', function (){    // stuff... });
