-.html

<input type="text" ng-focus="display = false" ng-blur="display = true" ng-init="display = true"> <p ng-show="display">aaa</p>  

如上述代码，focus/blur可以正常控制p标签的显示与隐藏

-.html

<input type="text" ng-focus="display = false" ng-blur="hide()" ng-init="display = true"> <p ng-show="display">aaa</p> 

-controller.js

$scope.hide = function (){     $scope.display = true; };  

上述代码只要focus input，display一直为false， 求解。
