How to solve the problem of mobile keyboard blocking input box in Vue development

With the popularity of mobile devices, more and more web applications are widely used on mobile phones. However, during development, we often encounter a very common problem, that is, the keyboard on the mobile phone blocks the input box. When the user uses the input box to input, if the keyboard blocks the input box, it will cause inconvenience and trouble to the user. How to solve this problem in Vue development? Below, I'll introduce a few solutions.

Option 1: Use the vue-keyboard-viewport plug-in

vue-keyboard-viewport is a plug-in specially developed for Vue. It can solve the problem of the mobile phone keyboard blocking the input box. The plugin automatically adjusts the page layout to accommodate the appearance and disappearance of the keyboard. Using this plug-in is very simple. You only need to install the plug-in in the Vue project, introduce and use it in the input box component that needs to solve the keyboard occlusion problem. By calling the methods provided by the plug-in, the position and size of the input box can be dynamically changed to ensure that it is not blocked by the keyboard.

Option 2: Manually monitor the appearance and disappearance events of the keyboard

If you do not want to use a third-party plug-in, you can also solve the problem by manually monitoring the appearance and disappearance events of the keyboard. In the Vue component, you can use the life cycle hook functions created and destroyed provided by Vue to listen to the keyboard's appearance and disappearance events respectively. When the keyboard appears, you can move the input box up by changing the style of the component or scrolling the page to ensure that it is not blocked by the keyboard; when the keyboard disappears, restore the original position of the input box. This method requires monitoring and processing keyboard events, which is relatively complicated. But in situations where no suitable plugin is available, this is a viable solution.

Option 3: Use the scrollIntoView method of CSS

The scrollIntoView method of CSS can scroll the specified element into the visible area. This method can be used to solve the problem of the keyboard blocking the input box. In specific use, when the input box gains focus, this method can be called to scroll the input box to the visible area and ensure that it is not blocked by the keyboard. When the keyboard disappears, scroll the page back to its original position. This method is very simple, but there is a prerequisite that the container where the input box is located must be scrollable, otherwise this method cannot be used.

To sum up, in Vue development, the following solutions can be used to solve the problem of the mobile phone keyboard blocking the input box: using the vue-keyboard-viewport plug-in, manually monitoring the appearance and disappearance of the keyboard, using CSS scrollIntoView method. Which option to choose depends on the actual needs of the project, functional complexity, and time constraints. It should be noted that in actual development, we should try our best to consider user experience and effects, and choose the most suitable solution based on the actual situation to improve the ease of use and user satisfaction of the application.
