Example of how to implement the function of hiding the return key in Uniapp

In Uniapp, many pages will need to hide the return key. This requirement may be because we don’t want users to return at will in certain scenarios, or because we have customized return operations in the page. However, many developers don't know how to implement this requirement. This article will explain how to hide the back key in Uniapp.

Method 1: Page level control

In Uniapp, each page can have its ownuni-configconfiguration file. In this file, we can perform various configurations on the page, including whether to display the return key. The following is a simple example:

{ "navigationBarTitleText": "我的页面", "navigationBarBackgroundColor": "#ffffff", "navigationBarTextStyle": "black", "enablePullDownRefresh": true, "disableScroll": true, "disableSwipeBack": true // 隐藏返回键 }

In the above code, we added adisableSwipeBackattribute inuni-configand set it totrue, you can realize the function of hiding the return key. It should be noted that this method is for each page. If we need to hide the return key in multiple pages, we need to configure it in the respectiveuni-configfiles.

Method 2: Global configuration

If we need to hide the return key in the entire application, we can use theApp.vuefile for global configuration. In theApp.vuefile, we can also use theuni.setNavigationBar({})method to configure the navigation bar. The following is an example:

In the above code, in theonLaunchmethod, we use theuni.setNavigationBarmethod to configure the navigation bar andThe backButtonHiddenproperty is set totrueto achieve the effect of hiding the return key. It should be noted that this method is global and will affect the navigation bar of the entire application.

Method Three: Manual Control

In addition to the above two methods, we can also hide the return key through manual control. In this way, we need to listen to the return event in the page and control it manually. Here is an example:

In the above code, we listen to theonBackPressevent in the page and prevent the default return event in this event, thereby achieving the effect of hiding the return key. It should be noted that in this method, we need to manually control each page.

Through the above three methods, we can easily implement the function of hiding the return key in Uniapp. The choice needs to be based on specific scenarios.
