jquery - How to disable select based on other selected option? -

i have problem jquery function. want based on 1 selected option disable other select. in case, want disable select2 if option 1 select 1 chosen. use jquery function:

$(document).ready(function(e) { $('.select1').change(function(e) {     if ($('.select1').val()==1){         $('.select2').attr('disabled','disabled');     }     else{         $('.select2').removeattr('disabled');     } }) }); 

but works if first select option 2(or other option form select) , reselect option 1(i suppose because use of change function). how disable select2 when default select1 set option 1???

$(document).ready(function(e) {     if ($('.select1').val()==1){     $('.select2').attr('disabled','disabled'); } else{     $('.select2').removeattr('disabled'); } }) 

this wont work :/

it sounds want trigger 'change' event @ startup.

$('.select1').trigger('change'); 

so,

$(document).ready(function(e) {     $('.select1').change(function(e) {         if ($('.select1').val()==1){             $('.select2').attr('disabled','disabled');         }         else{             $('.select2').removeattr('disabled');         }     });     $('.select1').trigger('change'); });
