Ionic 2 prevent hardware back button default

由 佐手、 提交于 2019-11-27 07:21:58
问题 How can I prevent default navigation when pressing hardware back button? I've tried registerBackButtonAction , but then it overwrites behavior of back button in every page which I don't want. This didn't help either. document.addEventListener("backbutton", (event) => { event.preventDefault(); }, false); 回答1: As you can see in Ionic docs registerBackButtonAction returns a function: A function that, when called, will unregister its back button action. So you can use that function to restore the

由 China☆狼群 提交于 2019-11-27 05:45:35
问题 I need to display side menu items according to the role of the user. so I check in app.html if the page (role) is equal to logged in role.
