[解決済み] Adding options to a <select> using jQuery?

Question

What's the easiest way to add an option to a dropdown using jQuery?

Will this work?

$("#mySelect").append('<option value=1>My option</option>');

How to solved?

This did NOT work in IE8 (yet did in FF):

$("#selectList").append(new Option("option text", "value"));

This DID work:

var o = new Option("option text", "value");
/// jquerify the DOM object 'o' so we can use the html method
$(o).html("option text");
$("#selectList").append(o);
