angularjs – ng-focus和ng-blur对select DOM不起作用

<div ng-app ng-init="focus=false;blur=false;active=false"> 
<select ng-focus="focus=true;blur=false;" ng-blur="blur=true;focus=false;">
    <option>sdasdsa</option>
    <option>dsadsads</option>
</select>
    <input type="text" ng-class="{ myFocus: focus,myBlur: blur }">
</div>

    <br>
         <br>
              <br>
                   <br>

<div class="search-input" ng-init="focus=false;blur=false;active=false">
    <input type="text" ng-class="{ myFocus: focus,myBlur: blur }">
            <div class="selects">
              <div class="icon fluid select">
                <i  ng-class="{'large svg guests icon':rooms==2,'large svg guest icon':rooms==1,'active':{{focus}}}"></i>
                <label ng-click="closeCalendar()">
                  <select ng-model="rooms" name="rooms" class="fluid" name="rooms" focus-parent selecter required ng-focus="focus=true;blur=false;" ng-blur="blur=true;focus=false;">
                      <option value="1">Einzelzimmer</option>
                      <option value="2">Doppelzimmer</option>
                  </select>
                </label>
              </div>
            </div>
          </div>
