//方法一，借用ng-init实现<select ng-model="mySelect" ng-init="mySelect=0"><option value="0"></option><option value="1"></option><option value="2"></option></select>//方法二，借用ng-selected实现,但是此方法实现后model里面默认是没有值的哦<select ng-model="mySelect"><option value="0" ng-selected="0"></option><option value="1"></option><option value="2"></option></select>
