如何使用jquery 取下拉框中的值

代码如下
function fillTypeInfo(items, typeobj, typename) {
var contents = new Array();
contents.push({value: "", title: "请选择"});
for(var prop in items){
contents.push({value: items[prop]["id"], title: "" + items[prop]["dicCode"] + "--" + items[prop]["dicName"]});
}

    typeobj.select({
        title: "请选择",
        contents: contents
    }).on('change',function(){
        typename.val($(this).getValue());
    });
}

生成的htm如下
