推荐答案

（'#Level'）。val （）;

('#Level').val();

.ajax（{
url：'/ Trainees / FillDept'，
type：GET，
dataType：JSON ，
数据：{Level：levelId}，
成功：函数（离开）{

.ajax({ url: '/Trainees/FillDept', type: "GET", dataType: "JSON", data: { Level: levelId }, success: function (depart) {

（＃Department）。html（）; //在添加新列表之前清除

("#Department").html(""); // clear before appending new list
