[] 重置表单class ng-dirty

1.Form表单和input输入框都要有name

<form class="form-inline" name="userForm">        <div class="form-group" >            <label>姓名：</label>            <input type="text" class="form-control" name="userName" ng-blur="clearDirty()" ng-model="query.userName" placeholder="姓名"/>        </div>

2.JS里

$scope.clearDirty=function () {        if($scope.query.userName==''){            $(this)[0].userForm.$setPristine()            $(this)[0].userForm.$setUntouched()        }    }
