我如何使用for循環做出.append在<select>下拉

Question

這是我迄今爲止 我得到有關括號

var teachers = ['mrs ohara','mr decrenza','mrs poli']; 
$('#addteacher').on('click',function(){ 

     $('#home').hide(); 
     console.log(); 
     $('#home').append('<select id = "teacherdropdown"><option>heloo</option></select>'); 
     for (var i = 0;i++;i<teachers.length){ 
     $('#teacherdropdown').append("<option value = "+teachers[i]+">"+teachers[i]+"</option>"); 
     } 
})
