html代码：

填报部门：

JS代码：

/*获取下拉菜单*/

function showSel(){

$.ajax({

"type" : 'get',

"url": 地址,

"dataType" : "json",

"success" : function(data) {

var depart_list = data.data;

var opts = "";

for( var depart_index = 0 ; depart_index < depart_list.length; depart_index++ ){

var depart = depart_list[depart_index];

opts += ""+显示的名称.name+"";

}

// 查询界面

$("#addid").append(opts);

$("#addid").selectpicker("refresh");

}

});

}

这样就可以了。
