How to count the number of options in select using jquery -

i want compare number of items in 2 select elements(html). tried using length property(with jquery) says both select element have number of option =1. populating both select elements dynamically. do?

      var $options=$("#test_select");      $options.empty();      $.each(t_test_list,function(index,value){     $options.append($("<option>").text(value).attr("value",value));      });       var numdate=$("#date_select").length; var numtest=$("#test_select").length; alert(numdate); alert(numtest); if(numdate!=numtest)     {     alert("the number of dates not match test cases!!!");     } 

try this:

change:

var numdate=$("#date_select").length; var numtest=$("#test_select").length; 

to:

var numdate=$("#date_select").children('option').length; var numtest=$("#test_select").children('option').length; 

you need options length children of select not select length.
