jQuery function has to repeat to work -

-

i'm getting jquery , notice strange behavior in way of code executed. when execute function based on click action, function runs twice, first time "undefined" value click , second expected value. end result code "works" want understand i'm doing wrong causing unexpected behavior.

here's jquery code:

$(function() {  //$('#venue').buttonset().click(function(event, ui) { //$( '#venue' ).buttonset().live('click', function (event, ui) {    $('#venue').buttonset().unbind('click').bind('click', function(event, ui) {      var venuename = $("input[name='venue']:checked").val();      if (venuename == "venue2") {         alert("about deselect, venue: " + venuename);         $("#meallist option[value='dinner']").removeattr("selected");     } else {         alert("doing nothing, venue: " + venuename);     }   }); });

note 3 different ways of expressing click action @ top, derived jquery docs , previous answers on site. have same outcome. can try here:

thanks insight. i'm hoping it's simple newbie mistake.

you set click event on element containing inputs. if set directly on inputs works expected:

$('#venue').buttonset().find('input').click(function(event, ui) {
