如果值等于或在jquery中选择，则追加选择选项

Question

I have 2 select tags. second is depend on the first one. It is working if I check by only value, but I also need to check if is selected.

if(el.val() === "LOCATIONS" || el.is(' option:selected') ){
 $("#status option").remove();
 $("#status").append("<option value=''>All Packages</option><option value=''>KL</option>");
}

I'm trying to make depended select dropdown. if I remove el.is('option:selected') it appends the options based on the chosen option of 1st select. but it should also append the options if any option is selected on the first dropdown

here is jsfiddle

Well it works even if you check one condition ie the value of selected option. But to pass two conditions you have to use && operator and instead of el.is('option:selected') , you can change this to ("el:selected"); as below,

 $(document).ready(function() { var a = $("#source > option:selected").val(); if(a == "REGIONAL"){ $("#status option").remove(); $("#status").append("<option value=''>All Packages</option><option value='Airports'>Airports</option>"); } $("#source").change(function() { var el = $(this); if((el.val() === "AUDIENCES SEGMENT") && ('el:selected')) { $("#status option").remove(); $("#status").append("<option value=''>All Packages</option><option value='Youth'>Youth</option><option value='Working Adults'>Working Adults</option><option value='Family'>Family</option><option value='Travellers'>Travellers</option>"); } else if((el.val() === "REGIONAL") && ('el:selected')) { $("#status option").remove(); $("#status").append("<option value=''>All Packages</option><option value='Airports'>Airports</option>"); } else if((el.val() === "LOCATIONS") && ('el:selected')) { $("#status option").remove(); $("#status").append("<option value=''>All Packages</option><option value=''>KL</option>"); } }); });
