$.post("Employee_jobquery.action", {

"job.departmentId" : departmentId

}, function(obj) {

var list = eval(obj);//转格式

for (var i = 0; i < list.length; i++) { 

var html = "<option value="+list[i].id+">"+list[i].name + "</option>";

$("#job").append(html);//添加下拉项

}

}, "json");

 

1.根据getDepartmentId获得list_jobs

2.List<Object> list = new ArrayList<Object>();

for (Job j : list_jobs) {

       Map<String, Object>temp = new HashMap<String, Object>();

       temp.put("id",j.getId());

       temp.put("name", j.getName());

       list.add(temp);

}

JSONArray json = new JSONArray();

json.addAll(list);

out.print(json.toString());

return null;
