How to close the soft keyboard in uniapp

When developing mobile applications, we often need users to enter information in input boxes. However, in some cases, soft keyboards often affect the user experience of the application. When using the uniapp framework, we often need to turn off the soft keyboard to facilitate the use of the application. In this article, we will explore how to turn off the soft keyboard in uniapp.

In uniapp, we can use the native method to close the soft keyboard. One way is to click anywhere outside the input box. This will cause the keyboard to be hidden and the input box to lose focus. However, this approach may result in data loss or a poor user experience if the user accidentally clicks on another area on the page.

Another method is to hide the soft keyboard through JavaScript code. In uniapp, we can use the following code to close the soft keyboard:

document.activeElement.blur();

This line of code will cause the currently activated element to lose focus and close the soft keyboard. However, when the user performs other actions in the application, the code may not work properly, causing the keyboard to not close.

In uniapp, we can also use third-party plug-ins to realize the function of closing the soft keyboard. One of the commonly used plugins is vue-touch-keyboard. This plugin allows developers to control when the keyboard should be turned on or off. To use this plug-in, you need to add the following dependencies to the project:

npm i vue-touch-keyboard --save

Add the initial state of the keyboard in the Vue component:

data () {
  return {
    keyboardVisible: false 
  }
}

Then, when we need to open the keyboard, we can use the following code to open the keyboard :

this.keyboardVisible = true

Similarly, when we need to close the keyboard, we can use the following code:

this.keyboardVisible = false

This plugin allows publishing and subscribing events on the keyboard through a given event listener to enable and Disable the keyboard.

// 启用键盘
this.$touchkeyboard.emit('show')
// 关闭键盘
this.$touchkeyboard.emit('hide')
//订阅键盘隐藏事件
this.$touchkeyboard.on('hide', () => {
   // 在这里编写代码
})

In short, turning off the soft keyboard is an important step in Uniapp application development and can improve the user experience. In this article, we explore three ways to turn off the soft keyboard: natively, using JavaScript, and using a third-party plugin. We can choose the method that best suits us according to the needs of the project to implement the function of closing the soft keyboard.
