问题 I'm creating a navigation bar in AngularJS. I am showing and hiding the submenu 'div.farm-links' on mouseover and mouseleave respectively on 'div.menu-links'.

What is the difference between ng-if and ng-show/ng-hide

问题 I\'m trying to understand the difference between ng-if and ng-show / ng-hide , but they look the same to me. Is there a difference that I should keep in mind choosing to use one or the other? 回答1: ngIf The ngIf directive removes or recreates a portion of the DOM tree based on an expression.
