怎么遍历div，获取选中的

[oLuRenJia123]

我想遍历div， 需要知道哪些已经选中， 选中后会加上addClass('checked');  想通过hasClass('checked') 来知道哪些选中了

<div class="office-time-con office-time-slot" id="timeSoltCon">
                <div class="office-time-item slot_" data-time="1574632800">06:00</div>
                <div class="office-time-item slot_" data-time="1574634600">06:30</div>
                <div class="office-time-item slot_" data-time="1574636400">07:00</div>
                <div class="office-time-item slot_" data-time="1574638200">07:30</div>
                <div class="office-time-item slot_ disable" data-time="1574640000">08:00</div>
                <div class="office-time-item slot_ disable" data-time="1574641800">08:30</div>
                <div class="office-time-item slot_ disable" data-time="1574643600">09:00</div>
                <div class="office-time-item slot_ disable" data-time="1574645400">09:30</div>
                <div class="office-time-item slot_" data-time="1574647200">10:00</div>
                <div class="office-time-item slot_" data-time="1574649000">10:30</div>
                <div class="office-time-item slot_" data-time="1574650800">11:00</div>
                <div class="office-time-item slot_" data-time="1574652600">11:30</div>
                <div class="office-time-item slot_" data-time="1574654400">12:00</div>
                <div class="office-time-item slot_" data-time="1574656200">12:30</div>
                <div class="office-time-item slot_" data-time="1574658000">13:00</div>
            </div>
