多个分组树分别实现单选jq+angular

$scope.seletedGroup=[];
var $li=$("#departmentsContainer>ol>li");
$.each($li,function(index,obj){
    var radios= $(obj).find("input[type='radio']");
    $.each(radios,function(i,obj2){
        if(obj2.checked){
            var genderChecked=obj2.value;
            ($scope.seletedGroup).push(genderChecked);
            console.log(genderChecked);
        }
    });
});
