angularJs使用ng-repeat遍历后选中某一个的方法

 <div>  <button ng-repeat="t in deptName" class="deptDiv"    ng-class="{'deptDivOnclick':selected==t.name}"    ng-click="showDeptEmps(t.name )">{{ t.name }}  </button> </div>

 $scope.showDeptEmps = function (dName) {    $scope.selected = dName; //设置点击按钮背景颜色   };

$scope.deptName = [{name;"部门1"}，{name;"部门2"}，{name;"部门3"}，{name;"部门4"}]；

.deptDiv {   margin: 10px;   width: 30%;   font-size: 27px;   background-color: #A1CF6D;   color: white;   padding-top: 10px;   padding-bottom: 10px;   padding-left: 20px;   padding-right: 20px;  }  .deptDivOnclick {   background-color: #008000;  }
