jQuery实现标签子元素的添加和赋值方法

<div>
<span>科室:</span>
<select class="dept-name-show" style="width: 70%;">
</select>
</div>

<script>
$(function () {
var dname = $(".dept-name-show").eq(0);//选定<select>标签
var url = "${pagecontext.request.contextpath}/getdepts.do";//请求路径
$(".dept-name-show").click(function () {
$.get(
url,
function (res) {
var len = res.length;
var op = dname.children().length;
if (op < len) {
var pp = "<option></option>";
for (var i = 0; i < len; i++) {
dname.append(pp);
dname.children().eq(i).text(res[i].name);
}
}
}
)
})
})
</script>

list<dept> deptlist=null;
@requestmapping(value = "/getdepts",method = {requestmethod.get})
public void getdepts(httpservletresponse response) throws ioexception {
response.setcharacterencoding("utf-8");
response.setcontenttype("text/json;charset=utf-8");
if (deptlist == null){
deptlist = deptservice.findalldepts();
}else {
string res=json.tojsonstring(deptlist);
response.getwriter().write(res);
}
}
